DiabolicaTrix Posted August 10, 2016 Share Posted August 10, 2016 Hi, I'm trying to make a transparent block with an item inside. I want the item to have the same animation as a dropped item. I made the model and a tesr for it so I can render the item but I have no clue how do what I want. I tried looking into the TileEntityItemStackRenderer class to see how they are rendering the items on the ground (I believe it's the right class) and the only thing I found is this line: else if (block != Blocks.CHEST) net.minecraftforge.client.ForgeHooksClient.renderTileItem(itemStackIn.getItem(), itemStackIn.getMetadata()); So I went into the ForgeHooksClient class and found the above function but I couldn't find where the render is done. An image of the block: My classes: Block: package com.wartimepvp.blocks; import com.wartimepvp.tileentities.BlockShowcaseTileEntity; import net.minecraft.block.Block; import net.minecraft.block.BlockContainer; import net.minecraft.block.material.Material; import net.minecraft.block.state.IBlockState; import net.minecraft.creativetab.CreativeTabs; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.BlockRenderLayer; import net.minecraft.util.EnumBlockRenderType; import net.minecraft.world.World; import net.minecraftforge.fml.relauncher.Side; import net.minecraftforge.fml.relauncher.SideOnly; public class BlockShowcase extends BlockContainer { public BlockShowcase(Material material) { super(material); this.setResistance(5.0F); this.setHardness(1.0F); this.setCreativeTab(CreativeTabs.BUILDING_BLOCKS); } @SideOnly(Side.CLIENT) public BlockRenderLayer getBlockLayer() { return BlockRenderLayer.CUTOUT; } @Override public boolean isOpaqueCube(IBlockState state) { return false; } @Override public EnumBlockRenderType getRenderType(IBlockState state) { return EnumBlockRenderType.MODEL; } public boolean isFullCube(IBlockState state) { return true; } @Override public TileEntity createNewTileEntity(World worldIn, int meta) { return new BlockShowcaseTileEntity(); } } TileEntitySpecialRenderer: package com.wartimepvp.tesr; import net.minecraft.client.renderer.GlStateManager; import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer; import net.minecraft.tileentity.TileEntity; public class BlockShowcaseTileEntitySpecialRenderer extends TileEntitySpecialRenderer { @Override public void renderTileEntityAt(TileEntity te, double x, double y, double z, float partialTicks, int destroyStage) { GlStateManager.pushMatrix(); GlStateManager.translate(x, y + 0.2, z); GlStateManager.popMatrix(); } } Quote Link to comment Share on other sites More sharing options...

DiabolicaTrix Posted August 10, 2016 Author Share Posted August 10, 2016 I would you do that? I created a new instance of EntityItem but how do I render it? I never did this before, sorry if it seems obvious to you. EntityItem item; public BlockShowcaseTileEntitySpecialRenderer() { item = new EntityItem(Minecraft.getMinecraft().theWorld, 0, 0, 0, new ItemStack(Items.APPLE)); } @Override public void renderTileEntityAt(TileEntity te, double x, double y, double z, float partialTicks, int destroyStage) { item.setPosition(x + 0.5, y + 0.1, z + 0.5); GlStateManager.pushMatrix(); GlStateManager.popMatrix(); } Quote Link to comment Share on other sites More sharing options...

DiabolicaTrix Posted August 10, 2016 Author Share Posted August 10, 2016 Ok so I looked at the RenderEntityItem class and tried to make something from this. What it looks like: Tesr: public class BlockShowcaseTileEntitySpecialRenderer extends TileEntitySpecialRenderer { private EntityItem item; private final Random random = new Random(); public BlockShowcaseTileEntitySpecialRenderer() { item = new EntityItem(Minecraft.getMinecraft().theWorld, 0, 0, 0, new ItemStack(Items.APPLE)); } @Override public void renderTileEntityAt(TileEntity te, double x, double y, double z, float partialTicks, int destroyStage) { boolean flag = false; if (this.bindEntityTexture(item)) { Minecraft.getMinecraft().getRenderManager().renderEngine.getTexture(this.getEntityTexture(item)).setBlurMipmap(false, false); flag = true; } GlStateManager.enableRescaleNormal(); GlStateManager.alphaFunc(516, 0.1F); GlStateManager.enableBlend(); RenderHelper.enableStandardItemLighting(); GlStateManager.tryBlendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ZERO); GlStateManager.pushMatrix(); IBakedModel ibakedmodel = Minecraft.getMinecraft().getRenderItem().getItemModelWithOverrides(new ItemStack(Items.APPLE), te.getWorld(), (EntityLivingBase)null); int j = this.transformModelCount(item, x, y, z, partialTicks, ibakedmodel); boolean flag1 = ibakedmodel.isGui3d(); if (!flag1) { float f3 = -0.0F * (float)(j - 1) * 0.5F; float f4 = -0.0F * (float)(j - 1) * 0.5F; float f5 = -0.09375F * (float)(j - 1) * 0.5F; GlStateManager.translate(f3, f4, f5); } for (int k = 0; k < j; ++k) { if (flag1) { GlStateManager.pushMatrix(); if (k > 0) { float f7 = (this.random.nextFloat() * 2.0F - 1.0F) * 0.15F; float f9 = (this.random.nextFloat() * 2.0F - 1.0F) * 0.15F; float f6 = (this.random.nextFloat() * 2.0F - 1.0F) * 0.15F; GlStateManager.translate(shouldSpreadItems() ? f7 : 0, shouldSpreadItems() ? f9 : 0, f6); } ibakedmodel = net.minecraftforge.client.ForgeHooksClient.handleCameraTransforms(ibakedmodel, ItemCameraTransforms.TransformType.GROUND, false); Minecraft.getMinecraft().getRenderItem().renderItem(new ItemStack(Items.APPLE), ibakedmodel); GlStateManager.popMatrix(); } else { GlStateManager.pushMatrix(); if (k > 0) { float f8 = (this.random.nextFloat() * 2.0F - 1.0F) * 0.15F * 0.5F; float f10 = (this.random.nextFloat() * 2.0F - 1.0F) * 0.15F * 0.5F; GlStateManager.translate(f8, f10, 0.0F); } ibakedmodel = net.minecraftforge.client.ForgeHooksClient.handleCameraTransforms(ibakedmodel, ItemCameraTransforms.TransformType.GROUND, false); Minecraft.getMinecraft().getRenderItem().renderItem(new ItemStack(Items.APPLE), ibakedmodel); GlStateManager.popMatrix(); GlStateManager.translate(0.0F, 0.0F, 0.09375F); } } GlStateManager.popMatrix(); GlStateManager.disableRescaleNormal(); GlStateManager.disableBlend(); this.bindEntityTexture(item); if (flag) { Minecraft.getMinecraft().renderEngine.getTexture(this.getEntityTexture(item)).restoreLastBlurMipmap(); } } protected boolean bindEntityTexture(EntityItem entity) { ResourceLocation resourcelocation = this.getEntityTexture(entity); if (resourcelocation == null) { return false; } else { this.bindTexture(resourcelocation); return true; } } protected ResourceLocation getEntityTexture(EntityItem entity) { return TextureMap.LOCATION_BLOCKS_TEXTURE; } private int transformModelCount(EntityItem itemIn, double p_177077_2_, double p_177077_4_, double p_177077_6_, float p_177077_8_, IBakedModel p_177077_9_) { ItemStack itemstack = itemIn.getEntityItem(); Item item = itemstack.getItem(); if (item == null) { return 0; } else { boolean flag = p_177077_9_.isGui3d(); int i = 1; float f = 0.25F; float f1 = shouldBob() ? MathHelper.sin(((float)itemIn.getAge() + p_177077_8_) / 10.0F + itemIn.hoverStart) * 0.1F + 0.1F : 0; float f2 = p_177077_9_.getItemCameraTransforms().getTransform(ItemCameraTransforms.TransformType.GROUND).scale.y; GlStateManager.translate((float)p_177077_2_, (float)p_177077_4_ + f1 + 0.25F * f2, (float)p_177077_6_); if (flag || Minecraft.getMinecraft().getRenderManager().options != null) { float f3 = (((float)itemIn.getAge() + p_177077_8_) / 20.0F + itemIn.hoverStart) * (180F / (float)Math.PI); GlStateManager.rotate(f3, 0.0F, 1.0F, 0.0F); } GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F); return i; } } public boolean shouldSpreadItems() { return true; } public boolean shouldBob() { return true; } } Even if the apple is dark, we can see that the texture is applied. Also, I can't show you with a picture but the apple is shaking a bit. It looks like it's trying to rotate but due to the fact that the function is called every tick, the position is reset. I should be able to fix this by myself but I'm going to need help to fix the color of the apple as I don't even know where to look. Quote Link to comment Share on other sites More sharing options...
Animefan8888 Posted August 10, 2016 Share Posted August 10, 2016 Re position the spot where you are rendering to center on the block(doubles/floats), and disable the lighting in GL11 or enable which ever works.

DiabolicaTrix Posted August 10, 2016 Author Share Posted August 10, 2016 Ok, so I tried to look into the RenderEntityItem to see how they animate the entity but I couldn't find anything about the animation. Now, my item is rendering in the block but the problem is that it's shacking. It looks like the item is trying to animate but the position is reset every tick so I guess the animation is achieved by modifying the x y z but I couldn't find where the doRender function is called.

Animefan8888 Posted August 10, 2016 Share Posted August 10, 2016 What are you trying to animate exactly the rotation or the up and down motion. Because the rotation is messing with the yaw/pitch, and the up and down can be handled using the motionY. And don't set the position every tick when you create it is when you should set it.

DiabolicaTrix Posted August 10, 2016 Author Share Posted August 10, 2016 I'm trying to make the same animation as a dropped item, I used the exact same code as in the RenderEntityItem but the item is not spinning up and down, it's shacking like I showed you in the video. I'm trying to find a way to fix this. Quote Link to comment Share on other sites More sharing options...
Animefan8888 Posted August 10, 2016 Share Posted August 10, 2016 The render code doesn't handle the yaw/pitch changes or the motion changes it grabs those from the EntityItem. Create the EntityItem in your TileEntity and call EntityItem.update in your TE's update method.

DiabolicaTrix Posted August 11, 2016 Author Share Posted August 11, 2016 So I tried to copy the update method of the EntityItem class and modify it to adapt it to my needs. I also tried to only set the position once but it didn't work, the item is following me and I don't even know why it does. I don't understand why the item is attached to the player but whatever. Also, I don't know if it's related but I can't take screenshots anymore, I'm getting an error: [20:31:54] [Client thread/ERROR]: ########## GL ERROR ########## [20:31:54] [Client thread/ERROR]: @ Pre render [20:31:54] [Client thread/ERROR]: 1282: Invalid operation My code: private EntityItem item; private final Random random = new Random(); private boolean first = true; public BlockShowcaseTileEntitySpecialRenderer() { item = new EntityItem(Minecraft.getMinecraft().theWorld, 0, 0, 0, new ItemStack(Items.BAKED_POTATO)); } public void update() { if (item.getEntityItem() == null) { item.setDead(); } else { item.prevPosX = item.posX; item.prevPosY = item.posY; item.prevPosZ = item.posZ; if (!item.hasNoGravity()) { item.motionY -= 0.03999999910593033D; } float f = 0.98F; if (item.onGround) { f = item.worldObj.getBlockState(new BlockPos(MathHelper.floor_double(item.posX), MathHelper.floor_double(item.getEntityBoundingBox().minY) - 1, MathHelper.floor_double(item.posZ))).getBlock().slipperiness * 0.98F; } item.motionX *= (double)f; item.motionY *= 0.9800000190734863D; item.motionZ *= (double)f; if (item.onGround) { item.motionY *= -0.5D; } } } @Override public void renderTileEntityAt(TileEntity te, double x, double y, double z, float partialTicks, int destroyStage) { ItemStack itemstack = new ItemStack(Items.BAKED_POTATO); if(first) { item.setPosition(x, y, z); first = false; } x = item.posX; y = item.posY; z = item.posZ; z += 0.5; y += 0.0; z += 0.5; int i; if (itemstack != null && itemstack.getItem() != null) { i = Item.getIdFromItem(itemstack.getItem()) + itemstack.getMetadata(); } else { i = 187; } this.random.setSeed((long)i); boolean flag = false; if (this.bindEntityTexture(item)) { Minecraft.getMinecraft().getRenderManager().renderEngine.getTexture(this.getEntityTexture(item)).setBlurMipmap(false, false); flag = true; } GlStateManager.enableRescaleNormal(); GlStateManager.alphaFunc(516, 0.1F); GlStateManager.enableBlend(); RenderHelper.enableStandardItemLighting(); GlStateManager.tryBlendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA,GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE,GlStateManager.DestFactor.ZERO); GlStateManager.pushMatrix(); IBakedModel ibakedmodel = Minecraft.getMinecraft().getRenderItem().getItemModelWithOverrides(new ItemStack(Items.BAKED_POTATO), te.getWorld(), (EntityLivingBase) null); int j = this.transformModelCount(item, x, y, z, partialTicks, ibakedmodel); boolean flag1 = ibakedmodel.isGui3d(); if (!flag1) { float f3 = -0.0F * (float)(j - 1) * 0.5F; float f4 = -0.0F * (float)(j - 1) * 0.5F; float f5 = -0.09375F * (float)(j - 1) * 0.5F; GlStateManager.translate(f3, f4, f5); } if (flag1) { GlStateManager.pushMatrix(); ibakedmodel = net.minecraftforge.client.ForgeHooksClient.handleCameraTransforms(ibakedmodel,ItemCameraTransforms.TransformType.GROUND, false); Minecraft.getMinecraft().getRenderItem().renderItem(new ItemStack(Items.BAKED_POTATO), ibakedmodel); GlStateManager.popMatrix(); } else { GlStateManager.pushMatrix(); ibakedmodel = net.minecraftforge.client.ForgeHooksClient.handleCameraTransforms(ibakedmodel,ItemCameraTransforms.TransformType.GROUND, false); Minecraft.getMinecraft().getRenderItem().renderItem(new ItemStack(Items.BAKED_POTATO), ibakedmodel); GlStateManager.popMatrix(); GlStateManager.translate(0.0F, 0.0F, 0.09375F); } GlStateManager.popMatrix(); GlStateManager.disableRescaleNormal(); GlStateManager.disableBlend(); this.bindEntityTexture(item); if (flag) { Minecraft.getMinecraft().renderEngine.getTexture(this.getEntityTexture(item)).restoreLastBlurMipmap(); } this.update(); } protected boolean bindEntityTexture(EntityItem entity) { ResourceLocation resourcelocation = this.getEntityTexture(entity); if (resourcelocation == null) { return false; } else { this.bindTexture(resourcelocation); return true; } } protected ResourceLocation getEntityTexture(EntityItem entity) { return TextureMap.LOCATION_BLOCKS_TEXTURE; } private int transformModelCount(EntityItem itemIn, double p_177077_2_, double p_177077_4_, double p_177077_6_, float p_177077_8_, IBakedModel p_177077_9_) { ItemStack itemstack = itemIn.getEntityItem(); Item item = itemstack.getItem(); if (item == null) { return 0; } else { boolean flag = p_177077_9_.isGui3d(); int i = 1; float f = 0.25F; float f1 = shouldBob() ?

MathHelper.sin(((float) itemIn.getAge() + p_177077_8_) / 10.0F + itemIn.hoverStart) * 0.1F + 0.1F : 0; float f2 = p_177077_9_.getItemCameraTransforms().getTransform(ItemCameraTransforms.TransformType.GROUND).scale.y; GlStateManager.translate((float) p_177077_2_, (float) p_177077_4_ + f1 + 0.25F * f2, (float) p_177077_6_); if (flag || Minecraft.getMinecraft().getRenderManager().options != null) { float f3 = (((float) itemIn.getAge() + p_177077_8_) / 20.0F + itemIn.hoverStart) * (180F / (float) Math.PI); GlStateManager.rotate(f3, 0.0F, 1.0F, 0.0F); } GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F); return i; } } public boolean shouldSpreadItems() { return true; } public boolean shouldBob() { return true; } } Tile Entity: public class BlockShowcaseTileEntity extends TileEntity implements ITickable { public EntityItem item; public BlockShowcaseTileEntity() { item = new EntityItem(Minecraft.getMinecraft().theWorld, this.pos.getX(), this.pos.getY(), this.pos.getZ(), new ItemStack(Items.BAKED_POTATO)); } @Override public void update() { if (item.getEntityItem() == null) { item.setDead(); } else { item.prevPosX = item.posX; item.prevPosY = item.posY; item.prevPosZ = item.posZ; if (!item.hasNoGravity()) { item.motionY -= 0.03999999910593033D; } float f = 0.98F; if (item.onGround) { f = item.worldObj.getBlockState(new BlockPos(MathHelper.floor_double(item.posX), MathHelper.floor_double(item.getEntityBoundingBox().minY) - 1, MathHelper.floor_double(item.posZ))).getBlock().slipperiness * 0.98F; } item.motionX *= (double)f; item.motionY *= 0.9800000190734863D; item.motionZ *= (double)f; if (item.onGround) { item.motionY *= -0.5D; } } } } EDIT: Thanks to everyone, I finally found out why the item wasn't moving: the render uses the age of the item to animate it but the age of my item wasn't updating so I just created a int and I add 1 every tick.
