  • How can I apply different actions to different parts of a 2D character?

    - by Praveen Sharath
    I am developing a 2D platform game in Java. The player has a gun in his hand every time. He needs to walk and shoot with the gun(arrow keys for walk and X key to shoot). The walk cycle takes 6 frames and i am able to import the sprite sheet and animate the sequence when I press arrow key. But i need to add the gun motion. The player holds the gun upwards and when X key is pressed he brings it straight and shoots. How to implement the walk + shoot action?

  • iOS : Creating a 3D Compass

    Originally posted here: iOS : Creating a 3D Compass Hi everybody, Quite new in this forum.Posted the same question in stackoverflow and there some people suggested to shift it here, so that I can get a quick help from more specialists in this regard.

That is when you touch it by 3 fingers and try to move your fingers upward the cover keeps moving with your fingers and after certain distance it gets opened.Once you pull it down using 3 fingers again, it gets closed.I can not attach an image here as I don't have that much reputation. So I request you to check the original question at stack overflow that I linked at top. Is it possible using core animations and CALayers? Or would I have to use OpenGL ES? Please someone help me out, I am badly in need of it.And I need to complete it asap!

  • Ubuntu 12.04.3 64 bit with Nemo 2.0.x no thumbnails

    - by Dr. Szrapnel
    I have strange problem with thumbnails in my Ubuntu machine. I was using Ubuntu with Cinnamon 1.8 from stable ppa and it was good but then Cinnamon 2.0 came out with some broken packages uploaded to stable ppa nad things gone wrong... Anyway after few updates Cinnamon started to work normaly except Nemo - there are no thumbnails at all, only icons. I heve tried purging /.cache/thumbnails and .thumbnails folders but this doesn't work. Next I have changed permissions for those folders - that didn't helped either. Then I've set Nemo as default file manager and desktop handler but with no result. What is weird - when I start Nautilus and open some folder with images then close it and open same folder with Nemo thumbnails appears but when I clean thumbnails directories there are no thumbnails again. It would be great if someone have some solution for this annoying Nemo behavior because I really don't want to resign from Cinnamon. p.s. I have set preview options in Nemo for Always and no bigger files than 4GB so that is not the case.

  • Toon shader with Texture. Can this be optimized?

    - by Alex
    I am quite new to OpenGL, I have managed after long trial and error to integrate Nehe's Cel-Shading rendering with my Model loaders, and have them drawn using the Toon shade and outline AND their original texture at the same time. The result is actually a very nice Cel Shading effect of the model texture, but it is havling the speed of the program, it's quite very slow even with just 3 models on screen... Since the result was kind of hacked together, I am thinking that maybe I am performing some extra steps or extra rendering tasks that maybe are not needed, and are slowing down the game? Something unnecessary that maybe you guys could spot? Both MD2 and 3DS loader have an InitToon() function called upon creation to load the shader initToon(){ int i; // Looping Variable ( NEW ) char Line[255]; // Storage For 255 Characters ( NEW ) float shaderData[32][3]; // Storate For The 96 Shader Values ( NEW ) FILE *In = fopen ("Shader.txt", "r"); // Open The Shader File ( NEW ) if (In) // Check To See If The File Opened ( NEW ) { for (i = 0; i < 32; i++) // Loop Though The 32 Greyscale Values ( NEW ) { if (feof (In)) // Check For The End Of The File ( NEW ) break; fgets (Line, 255, In); // Get The Current Line ( NEW ) shaderData[i][0] = shaderData[i][1] = shaderData[i][2] = float(atof (Line)); // Copy Over The Value ( NEW ) } fclose (In); // Close The File ( NEW ) } else return false; // It Went Horribly Horribly Wrong ( NEW ) glGenTextures (1, &shaderTexture[0]); // Get A Free Texture ID ( NEW ) glBindTexture (GL_TEXTURE_1D, shaderTexture[0]); // Bind This Texture.

  • Regulating how much to draw based on how much was drawn last frame.

    - by Mike Howard
    I have a 3D game world on an iPhone (limited graphics speed), and I'm already regulating whether I draw each shape on the screen based on it's size and distance from the camera. Something like... if (how_big_it_looks_from_the_camera > constant) then draw What I want to do now is also take into account how many shapes are being drawn, so that in busier areas of the game world I can draw less than I otherwise would. I tried to do this by dividing how_big_it_looks by the number of shapes that were drawn last frame (well, the square root of this but I'm simplifying - the problem is the same). if (how_big_it_looks / shapes_drawn > constant2) then draw But the check happens at the level of objects which represent many drawn shapes, and if an object containing many shapes is switched on, it increases shapes_drawn lots and switches itself back off the next frame. It flickers on and off. I tried keeping a kind of weighted average of previous values, by each frame doing something like shapes_drawn_recently = 0.9 * shapes_drawn_recently + 0.1 * shapes_just_drawn, but of course it only slows the flickering down because of the nature of the feedback loop. Is there a good way of solving this? My project is in Objective-C, but a general algorithm or pseudo-code is good too. Thanks.

  • 14.04 LTS, 32-bit, Software Updater error "Failed to download repository information: Check your internet connection"

    - by Lucas W
    There isn't much to say about this one: when I run Software Updater, I get the above error message. That can't be good. Interestingly, when I click on "Settings..." and then close the settings dialogue that pops up, all of a sudden Software Updater successfully finds updates and installs them. I thought I should bring this to the attention of the Ubuntu community. sudo apt-get update returns the following: W: Failed to fetch http://ppa.launchpad.net/deluge-team/ppa/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. I have screen captures, but I don't have enough reputation points to post them.

  • How To Smoothly Animate From One Camera Position To Another

    - by www.Sillitoy.com
    The Question is basically self explanatory. I have a scene with many cameras and I'd like to smoothly switch from one to another. I am not looking for a cross fade effect but more to a camera moving and rotating the view in order to reach the next camera point of view and so on. To this end I have tried the following code: firstCamera.transform.position.x = Mathf.Lerp(firstCamera.transform.position.x, nextCamer.transform.position.x,Time.deltaTime*smooth); firstCamera.transform.position.y = Mathf.Lerp(firstCamera.transform.position.y, nextCamera.transform.position.y,Time.deltaTime*smooth); firstCamera.transform.position.z = Mathf.Lerp(firstCamera.transform.position.z, nextCamera.transform.position.z,Time.deltaTime*smooth); firstCamera.transform.rotation.x = Mathf.Lerp(firstCamera.transform.rotation.x, nextCamera.transform.rotation.x,Time.deltaTime*smooth); firstCamera.transform.rotation.z = Mathf.Lerp(firstCamera.transform.rotation.z, nextCamera.transform.rotation.z,Time.deltaTime*smooth); firstCamera.transform.rotation.y = Mathf.Lerp(firstCamera.transform.rotation.y, nextCamera.transform.rotation.y,Time.deltaTime*smooth); But the result is actually not that good.

  • Android Game Development problem with Speed = Distance / Time

    I have been coding speed for an object. I have made it so the object will move from one end of the screen to another at a speed depending on the screen size, at the monemt I have made it so it will take one second to pass the screen. So i have worked out the speed in code but when I go to assign the speed it tells me to force close and i do not understand why. Here is the code: MainGame Code: @Override protected void onDraw(Canvas canvas) { setBlockSpeed(getWidth()); } private int blockSpeed; private void setBlockSpeed(int screenWidth){ Log.d(TAG, "screenWidth " + screenWidth); blockSpeed = screenWidth / 100; // 100 is the FPS.. i want it to take 1 second to pass the screen Math.round(blockSpeed); // to make it a whole number block.speed = blockSpeed; // this is line 318!! if i put eg block.speed = 8; it still tells me to force close } Block.java Code: public int speed; public void draw(Canvas canvas) { canvas.drawBitmap(bitmap, x - (bitmap.getWidth() / 2), y - (bitmap.getHeight() / 2), null); if(dontmove == 0){ this.x -= speed; // if it was eg this.x -= 18; it would not have an error } } The exception 06-08 13:22:34.315: E/AndroidRuntime(2801): FATAL EXCEPTION: Thread-11 06-08 13:22:34.315: E/AndroidRuntime(2801): java.lang.NullPointerException 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainGame.setBlockSpeed(MainGame.java:318) 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainGame.onDraw(MainGame.java:351) 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainThread.run(MainThread.java:64)

  • Exporting an animated FBX to XNA? (in 3DS Max)

    - by Itamar Marom
    I'm now working on an XNA 3D game, and I want to add animated models in it. I came across this example. I see there is one FBX file and a few texture files in the content project, and that in the code you can choose which "take" to play. In this code it is "Take_001". Please tell me: When I create and animate my own 3D model in 3DS Max (2012, since I was told it's only possible in this version), how can I define those takes? plus, are any configurations need to be made when exporting FBX from 3DS Max to XNA? Thank you.

  • Splitting a texture atlas into seperate images

    - by bigtunacan
    I'm doing a port of an existing game and the designer no longer has all of the original art; he only has the resulting texture atlases he used when developing for iPad. The tool I'm using won't support these files so I need to break them back out into separate PNG files. I'm hoping someone knows of a software tool that does this. PC software would be preferred in this case, but Mac would suffice.

  • XNA Skinned Model - Keyframe.Bone out of range exception

    - by idlackage
    I'm getting an IndexOutOfRangeException on this line of AnimationPlayer.cs: boneTransforms[keyframe.Bone] = keyframe.Transform; I don't get what it's really referring to. The error happens when keyframe.Bone is 14, but I have no idea what that's supposed to mean. The 14th bone of my model? What would that even be? I read this thread, but nothing there seemed to work. I don't have many bones, stray edges/verts, unassigned verts, unparented/non-root bones, or bones with dots in the name. What else can I be missing? Thank you for any help!

All tanks will have a bone called Body and a bone called Turret, and then names like Cannon0 and PickupGun for where the shots will be fired from that are attached to the Turret bone. Is there some way to find the absolute end position of a bone that I choose by name?

  • Dynamic model interactions

    - by Richard
    I am just curious as to how in many games (namely games like arkham asylum/city, manhunt, hitman) do they make it so that your character can "grab" a character in front of you and do stuff to them. I know this may sound very confusing but for an example go to youtube and search "hitman executions", and the first video is an example of what i'm asking. Basically I'm wondering how they make your model dynamically interact with whatever other model you come across, so in hitman when you come up behind some one with the fibre wire you strangle the other character or if you have the anesthetic you come up behind some person and put your hand over there mouth while they struggle and slowly go to the floor where you lay them down. I am confused as to whether it was animated to use two models using specific bone/skeletal identifiers, if it is just two completely separate animations that are played at the correct time to make it look like they are actually interacting or something else all together. I am not an animator so i assume most of what i just said is not right but i hope that some one can understand what i mean and provide an answer. PS) I am a programmer and I am in the process of building a hitmanesque game, just because i love that style of game and I want to increase my skills on something fun, so if you do know what i'm talking about have some examples with involving both models and programming (i use c++ and mainly Ogre3D at the moment but i am getting into unity and XNA) i would greatly appreciate it. Thanks.

  • Tips and Tools for creating Spritesheet animations

    - by Spooks
    I am looking for a tool that I can use to create sprite sheet easily. Right now I am using Illustrator, but I can never get the center of the character in the exact position, so it looks like it is moving around(even though its always in one place), while being loop through the sprite sheet. Is there any better tools that I can be using? Also what kind of tips would you give for working with a sprite sheet? Should I create each part of the character in individual layers (left arm, right arm, body, etc.) or everything at once? any other tips would also be helpful! thank you

With little game development experience (albeit having graphical skills and some programming knowledge) a group currently working on a game used to explain permaculture through interaction would like to create a simple concept game. Is there a specific engine or set of tools we could used to achieve this? Being able to make it an (online) multiplayer game would be much preferred. Thank you in advance for your input.

  • I have installed ubuntu into my windows 7 64 bit, i am having problems with boot

    - by noob
    I have a problem I have not found any solution to, I am not so familiar with ubuntu commands or ubuntu in general. My problem started when I chose in windows 7 settings/ bootloader settings as ubuntu default, and it boots straight into grub, and in grub if I choose windows, it goes to the loader for half a sec, and goes straight back to grub. So I have disabled my windows 7 completely. And I have not found any way to boot back to windows, so I could go to settings and set it to windows... My only option seems to be re-installing the whole Windows 7...thus loosing all my saved games etc... I am fine using ubuntu for basic needs, but I am getting desperate here...

  • Thunderbird keeps crashing Ubuntu 12.04 64 bit

    - by maurizio ribera d'alcala'
    I have been using Thunderbird for years under different versions of Ubuntu, including 12.04 since its release. From a couple of days it keeps crashing after a few seconds after start. I tried to reinstall it creating a new profile and copying the old mail, file by file. After one day of normal functioning it started again to crash. Mozilla is receiving the crash reports. Following is the content of the last one: Add-ons: [email protected]:15.0,[email protected]:0.3.11,[email protected]:0.9.3,[email protected]:3.4.1,[email protected]:15.0,[email protected]:0.5.1,{b4447f60-db9c-11da-a94d-0800200c9a66}:0.9.1,{972ce4c6-7e08-4474-a285-3208198ce6fd}:15.0 BuildID: 20120827103657 CrashTime: 1347200254 EMCheckCompatibility: true Email: [email protected] FramePoisonBase: 7ffffffff0dea000 FramePoisonSize: 4096 InstallTime: 1346431480 Notes: OpenGL: Tungsten Graphics, Inc -- Mesa DRI Intel(R) Sandybridge Mobile -- 3.0 Mesa 8.0.2 -- texture_from_pixmap ProductID: {3550f703-e582-4d05-9a08-453d09bdfdc6} ProductName: Thunderbird ReleaseChannel: release SecondsSinceLastCrash: 1109 StartupTime: 1347200242 Theme: classic/1.0 Throttleable: 1 Vendor: Version: 15.0 I started Thunderbird in safe mode and tested all the add-ons. Apparently is the 'Unity Launcher Integration' that creates the problem. I say apparently because I want two wait for two-three days to be sure TB returns to its regular functioning. Is this a bug? can it be solved

  • No monitor output after fresh install of 11.10 64-bit

    - by James
    I have a machine with a Nvidia 8600GT graphics card and a CRT monitor. Previously, I have only used Windows on it, and the graphics card seems to be working correctly in Windows 7. I booted up and installed Ubuntu 11.10 amd64 from the LiveCD and the whole process worked perfectly. When I tried to boot off the hard disk for the first time, the output to the monitor switched off during the splash screen, and this happens consistently. I can ctrl-alt-f2, so I tried an apt-get upgrade, which didn't help; nor did apt-get install nvidia-current. There is nothing that looks relevant in dmesg. Booting with the nomodeset option has no effect. Following the answers in this similar thread, I tried apt-get purge nvidia-173. Both startx and service lightdm start just say the service is already running. Does anyone know how to find out what the problem is? I was wondering if it is just that Ubuntu is trying to use a resolution that the monitor doesn't support, but I can't find out how to change that from the command line.
