  • Push back rectangle where collision happens

    - by Tifa
    I have a tile collision on a game I am creating but the problem is once a collision happens for example a collision happens in right side my sprite cant move to up and bottom :( thats because i set the speed to 0. I thinks its wrong. here is my code: int startX, startY, endX, endY; float pushx = 0,pushy = 0; // move player if(Gdx.input.isKeyPressed(Input.Keys.LEFT)){ dx=-1; currentWalk = leftWalk; } if(Gdx.input.isKeyPressed(Input.Keys.RIGHT)){ dx=1; currentWalk = rightWalk; } if(Gdx.input.isKeyPressed(Input.Keys.DOWN)){ dy=-1; currentWalk = downWalk; } if(Gdx.input.isKeyPressed(Input.Keys.UP)){ dy=1; currentWalk = upWalk; } sr.setProjectionMatrix(camera.combined); sr.begin(ShapeRenderer.ShapeType.Line); Rectangle koalaRect = rectPool.obtain(); koalaRect.set(player.getX(), player.getY(), pw, ph /2 ); float oldX = player.getX(), oldY = player.getY(); // THIS LINE WAS ADDED player.setXY(player.getX() + dx * Gdx.graphics.getDeltaTime() * 4f, player.getY() + dy * Gdx.graphics.getDeltaTime() * 4f); // THIS LINE WAS MOVED HERE FROM DOWN BELOW if(dx> 0) { startX = endX = (int)(player.getX() + pw); } else { startX = endX = (int)(player.getX() ); } startY = (int)(player.getY()); endY = (int)(player.getY() + ph); getTiles(startX, startY, endX, endY, tiles); for(Rectangle tile: tiles) { sr.rect(tile.x,tile.y,tile.getWidth(),tile.getHeight()); if(koalaRect.overlaps(tile)) { //dx = 0; player.setX(oldX); // THIS LINE CHANGED Gdx.app.log("x","hit " + player.getX() + " " + oldX); break; } } if(dy > 0) { startY = endY = (int)(player.getY() + ph ); } else { startY = endY = (int)(player.getY() ); } startX = (int)(player.getX()); endX = (int)(player.getX() + pw); getTiles(startX, startY, endX, endY, tiles); for(Rectangle tile: tiles) { if(koalaRect.overlaps(tile)) { //dy = 0; player.setY(oldY); // THIS LINE CHANGED //Gdx.app.log("y","hit" + player.getY() + " " + oldY); break; } } sr.rect(koalaRect.x,koalaRect.y,koalaRect.getWidth(),koalaRect.getHeight() / 2); sr.setColor(Color.GREEN); sr.end(); I want to push back the sprite when a collision happens but i have no idea how :D pls help

  • Adding interactive graphical elements to text-based browser game with HTML5

    - by st9
    I'm re-writing an old virtual world/browser based game. It is text and HTML form based with some static graphics. The client is HTML and JS. I want to introduce some interactive graphical elements to certain parts of the game, for example a 'customise character' page, with hooks to server side and local data storage. I want to use HTML5/JS, what is the best approach to designing the web-site? For example could I use Boilerplate and then embed these interactive elements in the page? Thanks

  • Brightness Crash and Fan issues in 12.04.1

    - by S.A. McIntosh
    I would just like to state beforehand that I am a total novice in using Ubuntu when it comes to the more complex issues. So I thought it would be best to finally come here and ask for help before being re-directed or closed out for a solution. I have already looked high and low on this board for one but nothing came up for my particular case, so I might as well take a shot asking for the first time here. This is what I have at the moment: -Dell Insprion 1764 w/ 64-bit Intel i5 Core -Dual Boot: Windows 7/Ubuntu 12.04.1 32-bit (from 12.04 install) -Unity shell -Linux kernel: 3.2.0-32 generic-pae ...and this is my fglrxinfo: OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 5000 Series OpenGL version string: 4.2.11627 Compatibility Profile Context The one issue I have with using Ubuntu is brightness. With the driver in every time I use the slider in the brightness and lock settings or use the keyboard function, it freezes, goes black and comes up with a scrambled colors page like this in the video. So I have looked all over this board and the web for answers looking for a solution that might have an answer. This is what I have done so far to fix this: -First Solution: Looking around, I found this small fix using terminal: sudo gedit /etc/rc.local followed by adding this into "rc.local" echo # > /sys/class/backlight/acpi_video0/brightness This works rarely with the graphics driver still in and I often get lucky say during restart but reboot would only snap back the brightness at max. -Second Solution Simply remove the graphics driver while leaving the solution of first behind. This solves the issue but results in having the monitor flicker and flash at startup which in itself is not a problem to me but maybe not so good for monitor health. Also it causes the fan to speed up throughout the session and render any program that needs the driver useless. -Third Solution This is the most obvious. Just simply use the brightness on AMD Catalyst Control Center software that came with the driver, and I can say that it's form of brightness is HORRIBLE compared to the actual settings. Which leads up to where I am now, back to the driver to stop the fan speed-up and seems that the only solution to the brightness crash is to use the keyboard-controlled brightness at the login screen NOT the desktop if I want the issued effect but will just snap at max bright again if I restart. Fan speed problem is dealt with but now run the risk of crashing my computer if I so much touch the brightness settings. Speaking of which I found this on launchpad and it seems that the issue has been going far since June of 2012. Any help, redirect link or reference would be greatly appreciated. Thank you.

  • Accidentally deleted /etc/X11/xorg.conf.original, and now log in no longer works

    - by Cester Nilap
    I accidentally deleted xorg.conf.original-0; xorg.conf.fglrx xorg.conf.fglrx-0-1, after I tried to install fglrx drivers on the graphics card, which in fact worked on 13.04 and now as I went to 13.10 has not worked. Now I can just switch to a new TTY with: Ctrl + Alt + F2 I found this which is for nVidia cards TO install the fglrx drivers for graphic card I used this tutorial Is there any possibility that I can recover, replace, rebuilb that xorg.conf.original-0, and if exists any possibility where I could start from.

  • How to implement a simple bullet trajectory

    - by AirieFenix
    I searched and searched and although it's a fair simple question, I don't find the proper answer but general ideas (which I already have). I have a top-down game and I want to implement a gun which shoots bullets that follow a simple path (no physics nor change of trajectory, just go from A to B thing). a: vector of the position of the gun/player. b: vector of the mouse position (cross-hair). w: the vector of the bullet's trajectory. So, w=b-a. And the position of the bullet = [x=x0+speed*time*normalized w.x , y=y0+speed*time * normalized w.y]. I have the constructor: public Shot(int shipX, int shipY, int mouseX, int mouseY) { //I get mouse with Gdx.input.getX()/getY() ... this.shotTime = TimeUtils.millis(); this.posX = shipX; this.posY = shipY; //I used aVector = aVector.nor() here before but for some reason didn't work float tmp = (float) (Math.pow(mouseX-shipX, 2) + Math.pow(mouseY-shipY, 2)); tmp = (float) Math.sqrt(Math.abs(tmp)); this.vecX = (mouseX-shipX)/tmp; this.vecY = (mouseY-shipY)/tmp; } And here I update the position and draw the shot: public void drawShot(SpriteBatch batch) { this.lifeTime = TimeUtils.millis() - this.shotTime; //position = positionBefore + v*t this.posX = this.posX + this.vecX*this.lifeTime*speed*Gdx.graphics.getDeltaTime(); this.posY = this.posY + this.vecY*this.lifeTime*speed*Gdx.graphics.getDeltaTime(); ... } Now, the behavior of the bullet seems very awkward, not going exactly where my mouse is (it's like the mouse is 30px off) and with a random speed. I know I probably need to open the old algebra book from college but I'd like somebody says if I'm in the right direction (or points me to it); if it's a calculation problem, a code problem or both. Also, is it possible that Gdx.input.getX() gives me non-precise position? Because when I draw the cross-hair it also draws off the cursor position. Sorry for the long post and sorry if it's a very basic question. Thanks!

  • Game Review: God of Light

    Luckily I came across this title at a very early stage. If I remember correctly, I took notice of God of Light on Twitter right on the weekend it has been published on the Play Store. "Sit back and become immersed into the world of God of Light, the game that rethinks the physics puzzle genre with its unique environment exploration gameplay, amazing graphics and exclusive soundtrack created by electronic music icon UNKLE. Join cute game mascot, Shiny, on his way to saving the universe from the impending darkness. Play through a variety of exciting game worlds and dozens of levels with mind-blowing puzzles. Your goal is to explore game levels, seek for game objects that reflect, split, combine, paint, bend and teleport rays of light energy to activate the Sources of Life and bring light back to the universe." Mastering the various reflection items in God of Light is very easy to learn and new elements are introduced during the game. Amazing puzzle game Here's the initial review I posted on the Play Store: "Great change in puzzles Fantastic and refreshing concept of puzzle solving. The effects and the music match very well, putting the player in the right mood to game. Get enlightened and grow your skills until you are a true God of Light." And it remains true, even after completing the first realm completely. Similar to Quell it took me only a couple of hours during the evening to complete all levels in the available three realms, unfortunately. God of Light currently consists of 75 levels, well it's 25 in each realm to be precise, and the challenges are increasing. Compared to the iOS version from the AppStore, God of Light is available for free on Android - at least the first realm (25 levels). Unlocking the other two remaining realms is done through an in-app purchase. The visual appearance, the sound effects and the background music provided by UNKLE makes God of Light a superb package for any puzzle gamer. Whether it is simply reflecting light over multiple mirrors, or later on bending the rays of light with black holes, or using prisms to either split, enforce, or colourise your beam, God of Light is great fun and offers a good amount of joy. Check out the following screenshots for some impressions. God of Light: Astonishing graphics and visual appeal throughout the game God of Light - Introduction to the game during the first levels. New light items are introduced at each stage during the game play God of Light: Increasing complexity and puzzle fun Hopefully, Playmous is going to provide more astonishing looking realms and interesting gimmicks in future versions.

  • Help, i cant reference my vars!

    - by SystemNetworks
    I have a sub-class(let's call it sub) and it contains all the function of an object in my game. In my main class(Let's call it main), i connect my sub to main. (Example sub Code: s = new sub(); Then I put my sub function at the update method. Code: s.myFunc(); Becuase in my sub, i have booleans, integers, float and more. The problem is that I don't want to connect my main class to use my main's int, booleans and others. If i connect it, it will have a stack overflow. This is what I put in my sub: Code: package javagame; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.Input; import org.newdawn.slick.state.StateBasedGame; public class Armory { package javagame; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.Input; import org.newdawn.slick.state.StateBasedGame; public class Store { public Integer wood; public Float probePositionX; public Float probePositionY; public Boolean StoreOn; public Boolean darkBought; public Integer money; public Integer darkEnergy; public Integer lifeLeft; public Integer powerLeft; public void darkStores(GameContainer gc, StateBasedGame sbg, GameContainer gc2) { Input input1 = gc.getInput(); //Player need wood to enter(200) If not there will be an error. if(wood>=200) { //Enter Store! if(input1.isKeyDown(Input.KEY_Q)) { //Player must be in this cord! if((probePositionX>393 && probePositionX<555) && (probePositionY< 271 && probePositionY>171)) { //The Store is On StoreOn=true; } } } } } In my main (update function) I put: Code: s.darkBought = darkBought; s.darkEnergy = darkEnergy; s.lifeLeft = lifeLeft; s.money = money; s.powerLeft = powerLeft; s.probePositionX = probePositionX; s.probePositionY = probePositionY; s.StoreOn = StoreOn; s.wood = wood; s.darkStores(gc, sbg, gc); The problem is when I go to the place, and I press q, nothing shows up. It should show another image. Is there anything wrong???

  • Turning on collision crashes game

    - by MomentumGaming
    I am getting a null pointer excecption to both my sprite and level. I am working on my mob class, and when I try to move him and the move function is called, the game crashes after checking collision with a null pointer excecption. Taking out the one line that actually checks if the tile located in front of it fixes the problem. Also, if i keep collision ON but don't move the position of the mob (the spider) the game works fine. I will have collision, and the spider appears on the screen, only problem is, getting it to move causes this nasty error that i just can't fix. true Exception in thread "Display" java.lang.NullPointerException at com.apcompsci.game.entity.mob.Mob.collision(Mob.java:67) at com.apcompsci.game.entity.mob.Mob.move(Mob.java:38) at com.apcompsci.game.entity.mob.spider.update(spider.java:58) at com.apcompsci.game.level.Level.update(Level.java:55) at com.apcompsci.game.Game.update(Game.java:128) at com.apcompsci.game.Game.run(Game.java:106) at java.lang.Thread.run(Unknown Source) Here is my renderMob mehtod: public void renderMob(int xp,int yp,Sprite sprite,int flip) { xp -= xOffset; yp-=yOffset; for(int y = 0; y<32; y++) { int ya = y + yp; int ys = y; if(flip == 2||flip == 3)ys = 31-y; for(int x = 0; x<32; x++) { int xa = x + xp; int xs = x; if(flip == 1||flip == 3)xs = 31-x; if(xa < -32 || xa >=width || ya<0||ya>=height) break; if(xa<0) xa =0; int col = sprite.pixels[xs+ys*32]; if(col!= 0x000000) pixels[xa+ya*width] = col; } } } My spider class which determines the sprite and where I control movement, also rendering the spider onto the screen, when I increment ya to move the sprite, I get the crash, but without ya++, it runs flawlessly with a spider sprite on screen: package com.apcompsci.game.entity.mob; import com.apcompsci.game.entity.mob.Mob.Direction; import com.apcompsci.game.graphics.Screen; import com.apcompsci.game.graphics.Sprite; import com.apcompsci.game.level.Level; public class spider extends Mob{ Direction dir; private Sprite sprite; private boolean walking; public spider(int x, int y) { this.x = x <<4; this.y = y <<4; sprite = sprite.spider_forward; } public void update() { int xa = 0, ya = 0; ya++; if(ya<0) { sprite = sprite.spider_forward; dir = Direction.UP; } if(ya>0) { sprite = sprite.spider_back; dir = Direction.DOWN; } if(xa<0) { sprite = sprite.spider_side; dir = Direction.LEFT; } if(xa>0) { sprite = sprite.spider_side; dir = Direction.LEFT; } if(xa!= 0 || ya!= 0) { System.out.println("true"); move(xa,ya); walking = true; } else{ walking = false; } } public void render(Screen screen) { screen.renderMob(x, y, sprite, 0); } } This is th mob class that contains the move() method that is called in the spider class above. This move method calls the collision method. tile and sprite comes up null in the debugger: package com.apcompsci.game.entity.mob; import java.util.ArrayList; import java.util.List; import com.apcompsci.game.entity.Entity; import com.apcompsci.game.entity.projectile.DemiGodProjectile; import com.apcompsci.game.entity.projectile.Projectile; import com.apcompsci.game.graphics.Sprite; public class Mob extends Entity{ protected Sprite sprite; protected boolean moving = false; protected enum Direction { UP,DOWN,LEFT,RIGHT } protected Direction dir; public void move(int xa,int ya) { if(xa != 0 && ya != 0) { move(xa,0); move(0,ya); return; } if(xa>0) dir = Direction.RIGHT; if(xa<0) dir = Direction.LEFT; if(ya>0)dir = Direction.DOWN; if(ya<0)dir = Direction.UP; if(!collision(xa,ya)){ x+= xa; y+=ya; } } public void update() { } public void shoot(int x, int y, double dir) { //dir = Math.toDegrees(dir); Projectile p = new DemiGodProjectile(x, y,dir); level.addProjectile(p); } public boolean collision(int xa,int ya) { boolean solid = false; for(int c = 0; c<4; c++) { int xt = ((x+xa) + c % 2 * 14 - 8 )/16; int yt = ((y+ya) + c / 2 * 12 +3 )/16; if(level.getTile(xt, yt).solid()) solid = true; } return solid; } public void render() { } } Finally, here is the method in which i call the add() method for the spider to add it to the level: protected void loadLevel(String path) { try{ BufferedImage image = ImageIO.read(SpawnLevel.class.getResource(path)); int w = width =image.getWidth(); int h = height = image.getHeight(); tiles = new int[w*h]; image.getRGB(0, 0, w,h, tiles,0, w); } catch(IOException e){ e.printStackTrace(); System.out.println("Exception! Could not load level file!"); } add(new spider(20,45)); } I don't think i need to include the level class but just in case, I have provided a gistHub link for better context. It contains all of the full classes listed above , plus my entity class and maybe another. Thanks for the help if you decide to do so, much appreciated! Also, please tell me if i'm in the wrong section of stackeoverflow, i figured that since this is the gamign section that it belonged but debugging code normally goes into the general section.

  • MPEG-2 playback inconsistent

    - by DustByte
    Many years ago I gave up on Linux because video playback was choppy. Now I'm back, and video playback is still playing up... I have two MPEG files: good.mpg bad.mpg. Here is some information about the two files, using avprobe: My machine is Intel Core 2 Duo E8400 @ 3.00GHz x 2, 64-bit. I do not know what graphics card I have. I run Ubuntu 12.04. So far I have had no problems with YouTube and playback of various video files, including playback of the file good.mpg, included in the avprobe snapshot above. However, the file bad.mpg gives me headache! The file bad.mpg is produced by a respectable "Old-video-tapes-to-DVD" company. I converted over 10 Video-8 tapes to MPEG through them, and today I collected my hard drive containing the MPEG files. Unfortunately I have problem watching them! Here are some details: Using Totem Movie Player 3.0.1 works well for several seconds, then it gets choppy and the playback is not at all smooth. Also the player easily freezes for a while when trying to jump to another position in the file. Most strangely though, the total time is shown as 0:42 (42 seconds) instead of the true 00:39:11: The VLC media player is doing a better job. It shows the correct total length, but as soon as I jump in the video to a new position, it stalls. Playback also stalls after 30 seconds if I press play and leave it. Using Handbrake and choosing bad.mpg as the source, gives me: There is only one title to choose, and it is 6 min 53 seconds. I would have guessed the full 39 minutes of the video should have shown. Lastly, putting the file bad.mpg in Dropbox and viewing it on my iPad with the Dropbox app seems fine (disregard the lack of easy jumping forward due to real-time encoding when streaming it). My question is simple: What is going on?! Why do I have problem to play the MPEG-2 files I just paid good money for (the issue with bad.mpg applies to all files I had encoded)? Is it an issue with my particular Linux machine? The graphics card? But why has everything worked fine so far, and why does not the good.mpg file cause any problems?

  • What precautions should I take when moving a hard drive from one computer to another?

    - by Colin Dean
    I'm planning to move a hard drive from one server machine to another. The hard drive is an IDE drive. The motherboards are different, as are the memory and such. In this instance, graphics isn't a problem because this is just Ubuntu Server. Are there any precautions I should take, or steps I can do beforehand, in order to make this go as smoothly as possible? I've of course already backed up /home directories and configurations in /etc and /var.

  • Preferred way to render text in OpenGL

    - by dukeofgaming
    Hi, I'm about tu pick up computer graphics once again for an university project. For a previous project I used a library called ftgl that didn't leave me quite satisfied as it felt kind of heavy (I tried all rendering techniques, text rendering didn't scale very well). My question is, is there a good and efficient library for this?, if not, what would be the way to implement fast but nice looking text?. Some intended uses are: Floating object/character labels Dialogues Menus HUD Regards and thanks in advance. EDIT: Preferrably that it can load fonts

I want to install Ubuntu on my laptop but whenever I put the Ubuntu live CD in it and boot to it, the screen shows the Ubuntu logo and the four little dots then after about a minute or two the screen goes black. I can tell the screen is still on but it doesn't have anything on it. I'm beginning to wonder if its a driver problem but I can't really install the drivers when I cant even get Ubuntu to show anything except a loading screen. I've already tried using 12.04 and 12.10 and all the others down to Ubuntu 10. none of them worked. All the other versions don't even show the Ubuntu logo. I'd prefer to have Ubuntu 13.04 on it if its possible but I haven't had any luck finding a solution. I've also tried using WUBI installer in Windows 7 but all that did was make my computer slower for windows and it does the same with the screen when i boot it to Ubuntu. I'm trying to use Ubuntu alongside Windows 7. I cant find any solution on Google. It wont load anything and I know that there is a program called grub on Ubuntu that I used on my desktop computer when it had graphics trouble but the trouble with my desktop was minor things like the screen would flash and then show weird patterns on the screen. But I can't find anything on what to do with the HP laptop. Please help. I use this laptop a lot for games on Windows 7 and I just want to use Ubuntu for when I take my laptop to school and for school stuff. Edit: I just tried booting it in nomodeset and some other things and still didn't work. It did boot up but now when it goes to install alongside windows it crashes and says Ubuntu is forcing reboot or something like that Also, this question is different from the black screen at boot issue because when I do use nomodeset on my computer and select install Ubuntu it will go as far as the screen where you can choose to replace Windows or run alongside Windows. Then after I click continue it ejects the live CD and turns off my computer without installing anything. The error message it shows when it ejects the disk says signal 15, shutting down - modem manager [1675]: <info> Caught nm-dispatcher.action: Caught signal 15, shutting down... *Deconfiguring network interfaces... Please remove installation media and close the tray (if any) then press ENTER *Deactivating swap... *Stopping remaining crypto disks... *stopping early crypto disks... unmount: /run/lock: not mounted unmount: /run/shm: not mounted

  • Screen resolution is too low with open source drivers on Ubuntu 12.10

    - by Chintan Parikh
    I'm on an AMD graphics card. When I use the open source xserver-xorg-video-radeon driver, Gnome shell works fine but my screen resolution can't be set higher than 1024x768. However, when I'm on the closed source fglrx drivers, the screen resolution works fine, but gnome shell doesn't (it goes to gnome classic for some reason). Does anyone know how I can either get gnome shell to work with fglrx, or how I can set my screen resolution with xserver-xorg-video-radeon?
