  • Sun & Moon Movement

    - by Thomas Mosey
    I'm creating a 2D HTML5 Canvas Game and am stuck on how to go about animating my Sun & Moon. The current setup is basically setting the moon at -1024 on the X-axis and the sun at 0 and animating them at 1 pixel a second. My canvas width is 1024 pixels and whenever the sun/moons X position crosses over the width of the canvas, it's X position is then set to -1024 to repeat the animation. What I am trying to do is get it to sync up with my day/night cycles. Each day is 10000 ticks long (A tick being added every frame) with Day/Night being 50% each (5000 ticks each). What I am trying to calculate is what I'll need to add to the X position of each per frame to get the sun from an X of 0 to 1024 after 5000 ticks/frames. Any help is appreciated.

  • How can I restrict a group to reading only two particular folders with Windows Server?

    - by Lord Torgamus
    I have a group of users on Windows Server 2003 who need to be able to read the contents of two directories but not be able to access anything else on the server (including read-only access). One of the directories is K:\projectFour\config — and the other is similarly formatted — so it would be okay for group members to be able to list the contents of K:\ and K:\projectFour\ but not actually read anything in those directories. I've found several resources via SF/Google, including how to restrict individual folders/drives and how to allow users to only run specific executables, but that information ultimately didn't solve my issue. Sorry if this is a really simple thing to do, I'm usually a developer and don't know the first thing about servers or group policies. Finally, I should mention that this isn't a fully concrete question, as it will be implemented eventually but I don't personally have a copy of Windows Server 2003 to test with right now.

  • Many sources of movement in an entity system

    - by Sticky
    I'm fairly new to the idea of entity systems, having read a bunch of stuff (most usefully, this great blog and this answer). Though I'm having a little trouble understanding how something as simple as being able to manipualate the position of an object by an undefined number of sources. That is, I have my entity, which has a position component. I then have some event in the game which tells this entity to move a given distance, in a given time. These events can happen at any time, and will have different values for position and time. The result is that they'd be compounded together. In a traditional OO solution, I'd have some sort of MoveBy class, that contains the distance/time, and an array of those inside my game object class. Each frame, I'd iterate through all the MoveBy, and apply it to the position. If a MoveBy has reached its finish time, remove it from the array. With the entity system, I'm a little confused as how I should replicate this sort of behavior. If there were just one of these at a time, instead of being able to compound them together, it'd be fairly straightforward (I believe) and look something like this: PositionComponent containing x, y MoveByComponent containing x, y, time Entity which has both a PositionComponent and a MoveByComponent MoveBySystem that looks for an entity with both these components, and adds the value of MoveByComponent to the PositionComponent. When the time is reached, it removes the component from that entity. I'm a bit confused as to how I'd do the same thing with many move by's. My initial thoughts are that I would have: PositionComponent, MoveByComponent the same as above MoveByCollectionComponent which contains an array of MoveByComponents MoveByCollectionSystem that looks for an entity with a PositionComponent and a MoveByCollectionComponent, iterating through the MoveByComponents inside it, applying/removing as necessary. I guess this is a more general problem, of having many of the same component, and wanting a corresponding system to act on each one. My entities contain their components inside a hash of component type - component, so strictly have only 1 component of a particular type per entity. Is this the right way to be looking at this? Should an entity only ever have one component of a given type at all times?

  • Adjusting the rate of movement of different objects on the same timer

    - by theUg
    I have a series of objects moving along the straight lines. I want to implement slight changes of velocity of each of the object. Constraint is existing model of animation. I am new to this, and not sure if it is the best way to accommodate varying speeds, but what do I know? It is a Java application that repaints the panel every time the timer expires. Timer is set via swing.Timer object that is set by timer delay constant. Every time the game is stepped objects’ coordinates advanced by an increment constant. Most of the objects are of the same class. Is there fairly easy way to refactor existing system to allow changing velocity for an individual object? Is there some obvious common solution I am not aware about? Idea I am having right now is to set timer delay fairly small, and only move objects every so many cycles of animation so that the apparent speed can be adjusted by varying how often they get moved. But that seems fairly involved, and I do not think it is the most elegant solution in terms of performance what with repainting the whole frame every 3-5 milliseconds. Can it be done by advancing the objects so many (varying) times during the certain interval (let’s say 35ms for something like 28fps), and use repaint() method to redraw just individual object? Do I need to mess with pausing animation for smoothness at higher redraw rates? Is it common practise to check for collision at larger step interval, but draw animation a lot more frequently?

  • Group traffic shaping with traffic control?

    - by mmcbro
    I'm trying to limit the output bandwidth generated by an application with linux tc. This application sends me the source port of the request that I use has a filter to limit each user at a given downloadspeed. I feel that my setup could be managed way better if I had a better knowledge of linux tc. At the application level users are categorized as members of a group, each group have a limited bandwidth. Example : Members of group A : 512kbit/s Members of group B : 1Mbit/s Members of group C : 2Mbit/s When a user connects to the application, it retrieves the source port to the origin of the request from the user and sends me the source port and the bandwidth at which the user must be limited depending on group to which it belongs. With these informations I must add the appropriate rules so that the user (the source port in reality) is limited to the right bandwidth. If the user that connect isn't a member of any group it should be limited at a default bandwidth speed. I'm actually managing this by using a self made daemon that add or remove rules from when it receive a request from the application. With my little knowledge of tc I'm not able to limit other users (ones that aren't in a group, all others in fact) at a default speed and my configuration seems awful to me. Here is the base of my tc qdisc and classes : tc qdisc add dev eth0 root handle 1: htb tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbps ceil 125mbps To classify a user at a given speed I have to add one subclass and then associate one filter to it : # a member of group A tc class add dev eth0 parent 1:1 classid 1:11 htb rate 512kbps ceil 512kbps # tts associated filter to match his source port tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 50001 flowid 1:11 # a member of group A again tc class add dev eth0 parent 1:1 classid 1:12 htb rate 512kbps ceil 512kbps # tts associated filter to match his source port tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 61524 flowid 1:12 # a member of group B again tc class add dev eth0 parent 1:1 classid 1:13 htb rate 1000kbps ceil 1000kbps # tts associated filter to match his source port tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 57200 flowid 1:13 I already know that a source port could be the same if its coming from a different IP address the thing is the application is behind a proxy so I don't have to manage any IP address in that situation. I would like to know how to manage the fact that for all other users (request/source port, whatever you name it) could be limited at a given speed each. I mean that each connection should be able to use at max 100kbit/s for example, not a shared 100kbit/s. I also would like to know if there is a way to simplify my rules. I don't know if it is possible to use only one class per group and associate multiple filters to the same class so each users could be handled by one class and not one class per user. I appreciate any advice, thanks.

  • How to control an actor movement in UDK

    - by Mikalichov
    This might be very basic, but I couldn't find something relevant to what I need (see below). I am working on a very basic thing: a 3D environment with some buildings, and actors walking inside it. It looks like following: I mainly want to manage to have one actor standing around, idling, and another walking around the area. Right now, this is done through matinee + skeletal mesh groups, and forcing a looped animation on the actors: But I realize this is super caveman-level. So I've build an AnimTree, linking the idling and directional animations to the corresponding nodes. But then, I'm stuck. I added the AnimTree in the actors properties, but nothing happens. I've tried MoveToActor, but no success - is there a thing to set to allow an actor to move? Also, I place the actors on the map manually (they are supposed to be unique), should I spawn them instead? Every tutorial I find explains how to use an AnimTree for the player character, which is not what I want. I need a way to move the actors. I tried to look for AI tutorials, but only found UT3 bots-modifications, which is not what I need either. Since I have so much trouble finding how to do this through Kismet, I'm starting to suspect this has to be done through scripting/coding, but I would like to be sure there is no way to do it through Kismet before going that route. Every bit of answer about how to tell an actor something along the lines of "go in that direction as much as you can, then when you hit a wall turn 45° and continue" would be awesome. I'll be happy to move/edit the question if there is any problem with it

  • IPS Package Groups

    - by Alan_Solaris_RE
    IPS group packages consist solely of dependencies on other packages that make up a logical grouping of software. These are similar to, but not the equivalent of, Solaris 10 metaclusters. The main difference is that metaclusters are nested subsets ranging from a minimal install to nearly all packages on the media. Group packages have no such hierarchy. They can overlap other groups, or be completely disjoint sets. A group dependency is set this way in an IPS package manifest file: depend fmri=full/pkg/name type=group Current Solaris Groups Solaris currently has 4 system groups defined. These are used for different types of installation, and are included in the xml manifest files used by the various Solaris installers: Package Name Summary Description Default Installation For:  group/system/solaris-desktop Oracle Solaris Desktop Provides an Oracle Solaris desktop environment Live Media  group/system/solaris-large-server Oracle Solaris Large Server Provides an Oracle Solaris large server environment Text Installer  group/system/solaris-small-server Oracle Solaris Small Server Provides a useful command-line Oracle Solaris environment  Zones  group/system/solaris-auto-install  Oracle Solaris Automated Installer Client  Provides an Oracle Solaris Automated Installer client  Automated Installer There are also several "feature" groups such as AMP and GNU Developer Tools. These are provided for convenience, but are not used directly by any installers. Retrieving Group Package Information A listing of all current groups can be found with the command: pkg info -r group/* A listing of all the packages in a group can be obtained with: pkg contents -o fmri -H -rt depend -a type=group groupname An example: $ pkg contents -o fmri -H -rt depend -a type=group solaris-desktop archiver/gnu-tar audio/audio-utilities codec/flac codec/libtheora codec/ogg-vorbis codec/speex communication/im/pidgin etc. You can determine which package group is currently installed on your system: $ pkg list group/system/\* Output would look like: NAME (PUBLISHER) VERSION IFO group/system/solaris-desktop 0.5.11-0.175.0.0.0.0.0 i-- Note that there are not version numbers associated with a group package dependency. The package version that best fits the system will be used, based on other dependencies such as what is listed in incorporation files. Installing a Group To Install a group, simple use the group package name as you would any other package: $ pkg install solaris-small-server  If you want to exclude a package from installing, you can use the --reject flag: $ pkg install --reject audio/audio-utilities solaris-desktop Creating Your Own Group To create your own group package, you can follow the pkg(5) documentation on how to create a package, and use this action for each package that is part of your group:   depend fmri=full/pkg/name type=group

  • Mobile: Physics and movement actions

    - by meganegora
    I've been using spritekit for a while for a few small games. One thing I've noticed is that spritekit is the first game framework I've used that allows me to apply move actions to physics bodies. (without anything screwing up at least.) Are there any cross platform game frameworks I can use that allow move actions on physics bodies? Not impulses. I've used cocos2d in the past and when I tried ccmoveby on physics bodies the simulation would get totally confused. I rather not use cocos2d anyway. I'm asking because I want to make cross platform games and spritekit is iOS only.

  • Explaining Asteroids Movement code

  • Player Movement DirectX

    - by SullY
    I'm reading on a Book that's about Gamedevelopment with C++ and DirectX 9. There is something that interrests me: It says that playermovements are increasing with the power of the CPU. Becouse a faster CPU will move the player with every frame ( better CPU = better FPS ) To bypass it, it says you have just to multiplicate time*movementfactor . I'd like to know is there an another way to bypass it ?

  • Korea&rsquo;s Anti Abortion / Pro Life Movement

    - by Randy Walker
    The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

  • Set primary group of file or directory on Samba share from Windows

    - by Hubert Kario
    Short version: I have such situation on a Samba share: $ ls -lha total 12K drwxr-xr-x 3 hka Domain Users 4.0K Jan 11 17:07 . drwxrwxrwt 19 root root 4.0K Jan 11 17:06 .. drwxr-xr-x 2 hka Domain Users 4.0K Jan 11 17:07 dir A -rw-r--r-- 1 hka Domain Users 0 Jan 11 17:07 file A How am I able to change this to following using only Windows SMB/CIFS client (using 3rd party applications is OK) $ ls -lha total 12K drwxr-xr-x 3 hka Domain Users 4.0K Jan 11 17:07 . drwxrwxrwt 19 root root 4.0K Jan 11 17:06 .. drwxr-xr-x 2 hka ntpoweruser 4.0K Jan 11 17:07 dir A -rw-r--r-- 1 hka ntpoweruser 0 Jan 11 17:07 file A Rationale and background info I'm using POSIX ACLs on Samba shares. Together with acl group control for Samba, it allows me to delegate management of permissions to different users based on group membership. Thing is, when I create a new file on a Samba share, I'm unable to set its primary group (the one that grants permission to change its permissions). It's being set to my primary group (Domain Users) or group set using force group option in smb.conf share definition. Removing all groups in windows except the one I want to become the new primary group doesn't work. I can change it using chgrp group folder/ as regular user though shell, but it's suboptimal (not all users are *nix users). Trying to set new owner to group from Windows file permission window makes the Samba to return permission denied with following log entry: [2012/01/05 21:13:03.349734, 3] smbd/nttrans.c:1899(call_nt_transact_set_security_desc) call_nt_transact_set_security_desc: file = projects/project A/New folder, sent 0x1 [2012/01/05 21:13:03.349774, 3] smbd/posix_acls.c:1208(unpack_nt_owners) unpack_nt_owners: unable to validate owner sid for S-1-5-21-4526631811-884521863-452487935-11025 [2012/01/05 21:13:03.349804, 3] smbd/error.c:80(error_packet_set) error packet at smbd/nttrans.c(1909) cmd=160 (SMBnttrans) NT_STATUS_INVALID_OWNER The SID is correct and belongs to group I specified in GUI.

  • Cocos-2D asteroids style movement (iOS)

    - by bwheeler96
    So I have a CCSprite subclass, well call this Spaceship. Spaceship needs to move on a loop, until I say othersise by calling a method. The method should look something like - (void)moveForeverAtVelocity { // method logic } The class Spaceship has two relevant iVars, resetPosition and targetPosition, the target is where we are headed, the reset is where we set to when we've hit our target. If they are both off-screen this creates a permanent looping effect. So for the logic, I have tried several things, such as CCMoveTo *move = [CCMoveTo actionWithDuration:2 position:ccp(100, 100)]; CCCallBlockN *repeat = [CCCallBlockN actionWithBlock: ^(CCNode *node) { [self moveForeverAtVelocity]; }]; [self runAction:[CCSequence actions: move, repeat, nil]]; self.position = self.resetPosition; recursively calling the moveForeverAtVelocity method. This is psuedo-code, so its not perfect. I have hard-coded some of the values for the sake of simplicity. Enough garble: The problem I am having, how can I make a method that loops forever, but can be called and reset at will. I'm running into issues with creating multiple instances of this method. If you can offer any assistance with creating this effect, that would be appreciated.

  • Restrict movement within a radius

    - by Phil
    I asked a similar question recently but now I think I know more about what I really want to know. I can answer my own question if I get to understand this bit. I have a situation where a sprite's center point needs to be constrained within a certain boundary in 2d space. The boundary is circular so the sprite is constrained within a radius. This radius is defined as a distance from the center of a certain point. I know the position of the center point and I can track the center position of the sprite. This is the code to detect the distance: float distance = Vector2.Distance(centerPosition, spritePosition)); if (distance > allowedDistance) { } The positions can be wherever on the grid, they are not described as in between -1 or 1. So basically the detecting code works, it only prints when the sprite is outside of it's boundary I just don't know what to do when it oversteps. Please explain any math used as I really want to understand what you're thinking to be able to elaborate on it myself.

    I have an arraylist of entites that I want to move randomly. No matter what I do, they won't move. Here is my female class: import java.awt.Graphics2D; import java.awt.Image; import java.awt.Rectangle; import java.util.Random; import javax.swing.ImageIcon; public class Female extends Entity { static int femaleX = 0; static int femaleY = 0; double walkSpeed = .1f; Random rand = new Random(); int random; int dir; Player player; public Female(int posX, int posY) { super(posX, posY); } public void update() { posX += femaleX; posY += femaleY; } public void draw(Graphics2D g2d) { g2d.drawImage(getFemaleImg(), posX, posY, null); if (Player.showBounds == true) { g2d.draw(getBounds()); } } public Image getFemaleImg() { ImageIcon ic = new ImageIcon("res/female.png"); return ic.getImage(); } public Rectangle getBounds() { return new Rectangle(posX, posY, getFemaleImg().getHeight(null), getFemaleImg().getWidth(null)); } public void moveFemale() { random = rand.nextInt(3); System.out.println(random); if (random == 0) { dir = 0; posX -= (int) walkSpeed; } } } And here is how I update the female class in the main class: public void actionPerformed(ActionEvent ae) { player.update(); for(int i = 0; i < females.size(); i++){ Female tempFemale = females.get(i); tempFemale.update(); } repaint(); } If I do something like this(in the female update method): public void update() { posX += femaleX; posY += femaleY; posX -= walkSpeed; } The characters move with no problem. Why is this?

  • SDL Bullet Movement

    - by Code Assasssin
    I'm currently working on my first space shooter, and I'm in the process of making my ship shoot some bullets/lasers. Unfortunately, I'm having a hard time getting the bullets to fly vertically. I'm a total noob when it comes to this so you might have a hard time understanding my code :/ // Position Bullet Function projectilex = x + 17; projectiley = y + -20; if(keystates[SDLK_SPACE]) { alive = true; } And here's my show function if(alive) { if(frame == 2) { frame = 0; } apply_surface(projectilex,projectiley,ShootStuff,screen,&lazers[frame]); frame++; projectiley + 1; } I'm trying to get the bullet to fly vertically... and I have no clue how to do that. I've tried messing with the y coordinate but that makes things worse. The laser/bullet just follows the ship :( How would I get it to fire at the starting position and keep going in a vertical line without it following the ship? int main( int argc, char* args[] ) { Player p; Timer fps; bool quit = false; if( init() == false ) { return 1; } //Load the files if( load_files() == false ) { return 1; } clip[ 0 ].x = 0; clip[ 0 ].y = 0; clip[ 0 ].w = 30; clip[ 0 ].h = 36; clip[ 1 ].x = 31; clip[ 1 ].y = 0; clip[ 1 ].w = 39; clip[ 1 ].h = 36; clip[ 2 ].x = 71; clip[ 2 ].y = 0; clip[ 2 ].w = 29; clip[ 2 ].h = 36; lazers [ 0 ].x = 0; lazers [ 0 ].y = 0; lazers [ 0 ].w = 3; lazers [ 0 ].h = 9; lazers [ 1 ].x = 5; lazers [ 1 ].y = 0; lazers [ 1 ].w = 3; lazers [ 1 ].h = 7; while( quit == false ) { fps.start(); //While there's an event to handle while( SDL_PollEvent( &event ) ) { p.handle_input(); //If a key was pressed //If the user has Xed out the window if( event.type == SDL_QUIT ) { //Quit the program quit = true; } } //Scroll background bgX -= 8; //If the background has gone too far if( bgX <= -GameBackground->w ) { //Reset the offset bgX = 0; } p.move(); apply_surface( bgX, bgY,GameBackground, screen ); apply_surface( bgX + GameBackground->w, bgY, GameBackground, screen ); apply_surface(0,0, FullHealthBar,screen); p.shoot(); p.show(); //Apply the message //Update the screen if( SDL_Flip( screen ) == -1 ) { return 1; } SDL_Flip(GameBackground); if( fps.get_ticks() < 1000 / FRAMES_PER_SECOND ) { SDL_Delay( ( 1000 / FRAMES_PER_SECOND ) - fps.get_ticks() ); } } //Clean up clean_up(); return 0; }

  • How do I use Group Policy on a domain to delete Temporary Internet Files?

    - by Muhammad Ali
    I have a domain controller running on Windows 2008 Server R2 and users login to application servers on which Windows 2003 Server SP2 is installed. I have applied a Group Policy to clean temporary internet files on exit i.e to delete all temporary internet files when users close the browser. But the group policy doesn't seem to work as user profile size keeps on increasing and the major space is occupied by temporary internet files therefore increasing the disk usage. How can i enforce automatic deletion of temporary internet files?

    Hi there I'm a developer looking at introducing ClickOnce deployment for an internal .NET Winforms application that will be distributed via the corporate network. Currently the product roll out and updates are handled by Group Policy however I would like to control the updates via ClickOnce deployment now. What I would like to know is, how should I initially roll out the package to make sure that all users have got it. Can I use a combination of Group Policy (the roll out) and then rely on the ClickOnce deployment model for any further updates?

    I had a problem with a Win2k8 Domain Controller and had to restart it. It restarted with no issues and reached the "PRESS CTRL + DEL TO LOGON" screen. And so I did a usual logon with an administrative domain account and it started to apply group policy. It processed mapped drive and some other stuff before it reach printer policy and then it got stuck for more than an hour. What is the proper way to troubleshoot or abort applying group policy?

  • Extrapolation breaks collision detection

    - by user22241
    Before applying extrapolation to my sprite's movement, my collision worked perfectly. However, after applying extrapolation to my sprite's movement (to smooth things out), the collision no longer works. This is how things worked before extrapolation: However, after I implement my extrapolation, the collision routine breaks. I am assuming this is because it is acting upon the new coordinate that has been produced by the extrapolation routine (which is situated in my render call ). After I apply my extrapolation How to correct this behaviour? I've tried puting an extra collision check just after extrapolation - this does seem to clear up a lot of the problems but I've ruled this out because putting logic into my rendering is out of the question. I've also tried making a copy of the spritesX position, extrapolating that and drawing using that rather than the original, thus leaving the original intact for the logic to pick up on - this seems a better option, but it still produces some weird effects when colliding with walls. I'm pretty sure this also isn't the correct way to deal with this. I've found a couple of similar questions on here but the answers haven't helped me. This is my extrapolation code: public void onDrawFrame(GL10 gl) { //Set/Re-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip){ SceneManager.getInstance().getCurrentScene().updateLogic(); nextGameTick+=skipTicks; timeCorrection += (1000d/ticksPerSecond) % 1; nextGameTick+=timeCorrection; timeCorrection %=1; loops++; tics++; } extrapolation = (float)(System.currentTimeMillis() + skipTicks - nextGameTick) / (float)skipTicks; render(extrapolation); } Applying extrapolation render(float extrapolation){ //This example shows extrapolation for X axis only. Y position (spriteScreenY is assumed to be valid) extrapolatedPosX = spriteGridX+(SpriteXVelocity*dt)*extrapolation; spriteScreenPosX = extrapolationPosX * screenWidth; drawSprite(spriteScreenX, spriteScreenY); } Edit As I mentioned above, I have tried making a copy of the sprite's coordinates specifically to draw with.... this has it's own problems. Firstly, regardless of the copying, when the sprite is moving, it's super-smooth, when it stops, it's wobbling slightly left/right - as it's still extrapolating it's position based on the time. Is this normal behavior and can we 'turn it off' when the sprite stops? I've tried having flags for left / right and only extrapolating if either of these is enabled. I've also tried copying the last and current positions to see if there is any difference. However, as far as collision goes, these don't help. If the user is pressing say, the right button and the sprite is moving right, when it hits a wall, if the user continues to hold the right button down, the sprite will keep animating to the right, while being stopped by the wall (therefore not actually moving), however because the right flag is still set and also because the collision routine is constantly moving the sprite out of the wall, it still appear to the code (not the player) that the sprite is still moving, and therefore extrapolation continues. So what the player would see, is the sprite 'static' (yes, it's animating, but it's not actually moving across the screen), and every now and then it shakes violently as the extrapolation attempts to do it's thing....... Hope this help

  • XNA 2D Board game - trouble with the cursor

    - by Adorjan
    I just have started making a simple 2D board game using XNA, but I got stuck at the movement of the cursor. This is my problem: I have a 10x10 table on with I should use a cursor to navigate. I simply made that table with the spriteBatch.Draw() function because I couldn't do it on another way. So here is what I did with the cursor: public override void LoadContent() { ... mutato.Position = new Vector2(X, Y); //X=103, Y=107; mutato.Sebesseg = 45; ... mutato.Initialize(content.Load<Texture2D>("cursor"),mutato.Position,mutato.Sebesseg); ... } public override void HandleInput(InputState input) { if (input == null) throw new ArgumentNullException("input"); // Look up inputs for the active player profile. int playerIndex = (int)ControllingPlayer.Value; KeyboardState keyboardState = input.CurrentKeyboardStates[playerIndex]; if (input.IsPauseGame(ControllingPlayer) || gamePadDisconnected) { ScreenManager.AddScreen(new PauseMenuScreen(), ControllingPlayer); } else { // Otherwise move the player position. if (keyboardState.IsKeyDown(Keys.Down)) { Y = (int)mutato.Position.Y + mutato.Move; } if (keyboardState.IsKeyDown(Keys.Up)) { Y = (int)mutato.Position.Y - mutato.Move; } if (keyboardState.IsKeyDown(Keys.Left)) { X = (int)mutato.Position.X - mutato.Move; } if (keyboardState.IsKeyDown(Keys.Right)) { X = (int)mutato.Position.X + mutato.Move; } } } public override void Draw(GameTime gameTime) { mutato.Draw(spriteBatch); } Here's the cursor's (mutato) class: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; namespace Battleship.Components { class Cursor { public Texture2D Cursortexture; public Vector2 Position; public int Move; public void Initialize(Texture2D texture, Vector2 position,int move) { Cursortexture = texture; Position = position; Move = move; } public void Update() { } public void Draw(SpriteBatch spriteBatch) { spriteBatch.Draw(Cursortexture, Position, Color.White); } } } And here is a part of the InputState class where I think I should change something: public bool IsNewKeyPress(Keys key, PlayerIndex? controllingPlayer, out PlayerIndex playerIndex) { if (controllingPlayer.HasValue) { // Read input from the specified player. playerIndex = controllingPlayer.Value; int i = (int)playerIndex; return (CurrentKeyboardStates[i].IsKeyDown(key) && LastKeyboardStates[i].IsKeyUp(key)); } } If I leave the movement operation like this it doesn't have any sense: X = (int)mutato.Position.X - mutato.Move; However if I modify it to this: X = (int)mutato.Position.X--; it moves smoothly. Instead of this I need to move the cursor by fields (45 pixels), but I don't have any idea how to manage it.
