Draco18s Posted November 9, 2013 Share Posted November 9, 2013 Code is a bit messy, but essentially I'm waiting for an event, then calling readyTickHandler(). It waits a specified number of ticks (renderDelay) before performing the render. This is to allow time for the world to load. However, due to the delay, I do not want to render from the player's location after the delay, but rather from their original location and orientation. Here's the problem: Even though I'm setting the temporary entity's orientation, it's being ignored when the render happens, it's treated as always 0, regardless of its actual value. If I use the actual player as the temporary agent, then it gets rendered with the correct orientation values (that is, where the player is looking at the time). What do I need to change in order for the temporary entity to make it render correctly? public void readyTickHandler(World w, EntityPlayer pl) { world = w; p = new EntityRenderNode(world); world.spawnEntityInWorld(p); p.posX = pl.posX; p.posY = pl.posY; p.posZ = pl.posZ; p.rotationPitch = 0; p.rotationYaw = pl.rotationYaw; System.out.println("Yaw: " + pl.rotationYaw); renderDelay = 20*30; } @Override public void tickEnd(EnumSet<TickType> type, Object... tickData) { if(renderDelay > 0) { renderDelay--; } if(renderDelay == 0) { renderDelay = -1; System.out.println("Render Yaw: " + p.rotationYaw); //this is the function that handles the rendering. int[] data = renderWorldToTexture(p, 0.01F); //now we save the data. ByteArrayOutputStream bt = new ByteArrayOutputStream(); DataOutputStream out = new DataOutputStream(bt); try { //omitted for irrelevancy. } catch (IOException ex) { } //remove the temporary entity p.attackEntityFrom(DamageSource.outOfWorld, 100); } } private final int[] renderWorldToTexture(EntityLivingBase player, float renderTime) { GameSettings settings = mc.gameSettings; // dont want to access these fields every time EntityRenderer entityRenderer = mc.entityRenderer; RenderGlobal renderGlobalBackup = mc.renderGlobal; EntityLivingBase viewportBackup = mc.renderViewEntity; int heightBackup = mc.displayHeight; int widthBackup = mc.displayWidth; int thirdPersonBackup = settings.thirdPersonView; boolean hideGuiBackup = settings.hideGUI; int particleBackup = mc.gameSettings.particleSetting; mc.gameSettings.particleSetting = 2; int width = 128; int height = 128; mc.renderGlobal = mc.renderGlobal; mc.renderViewEntity = player; mc.displayHeight = height; mc.displayWidth = width; settings.thirdPersonView = 0; settings.hideGUI = true; int fps = EntityRenderer.performanceToFps(mc.gameSettings.limitFramerate); if (settings.limitFramerate == 0) { entityRenderer.renderWorld(renderTime, 0L); } else { entityRenderer.renderWorld(renderTime, (1000000000 / fps)); } int k = width * height; int[] dataarray = new int[k]; IntBuffer databuffer = BufferUtils.createIntBuffer(k); GL11.glPixelStorei(GL11.GL_PACK_ALIGNMENT, 1); GL11.glPixelStorei(GL11.GL_UNPACK_ALIGNMENT, 1); databuffer.clear(); GL11.glReadPixels(0, 0, width, height, GL12.GL_BGRA, GL12.GL_UNSIGNED_INT_8_8_8_8_REV, databuffer); databuffer.get(dataarray); reconfigureArray(dataarray, width, height); settings.thirdPersonView = thirdPersonBackup; settings.hideGUI = hideGuiBackup; mc.displayHeight = heightBackup; mc.displayWidth = widthBackup; mc.renderGlobal = renderGlobalBackup; mc.renderViewEntity = viewportBackup; mc.gameSettings.particleSetting = particleBackup; return dataarray; } //I actually have no idea what purpose this function serves, but Vanilla uses it with screenshots. private void reconfigureArray(int[] dataarray, int width, int height) { int[] aint1 = new int[width]; int k = height / 2; for (int l = 0; l < k; ++l) { System.arraycopy(dataarray, l * width, aint1, 0, width); System.arraycopy(dataarray, (height - 1 - l) * width, dataarray, l * width, width); System.arraycopy(aint1, 0, dataarray, (height - 1 - l) * width, width); } } Quote Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.

TheGreyGhost Posted November 10, 2013 Share Posted November 10, 2013 Hi Beats me! Have you tried looking in EntityRenderer.orientCamera() to see if you can figure it out using breakpoints? I also notice an interesting setting this.mc.gameSettings.debugCamEnable which might get you the control you need? -TGG Quote Link to comment Share on other sites More sharing options...
Draco18s Posted November 10, 2013 Author Share Posted November 10, 2013 I figured it out yesterday, pure guess. The rendered YAW is based on entity.rotationYawHead.
