Colored Glowing Effect on ItemStacks (on Ground)

[badner]

Hi,

I am trying to create a Mod which can show "Ghost-Items" in the world and cover them with a colored glowing effect. NOTICE: clientside only!

 

Here you can see how the "Ghost-Items" are generated: 

 

ghostEntity = new EntityItem(mc.player.getEntityWorld(), 0, 70, 0, new ItemStack(Blocks.COBBLESTONE));

 

To render the Ghost-Items, I created a custom renderer which can render the Ghost-Item at a specific location in the world: (based on RenderEntityItem.class)

 

public void doRender(EntityItem entity, double xPos, double yPos, double zPos, float entityYaw, float partialTicks) {
		
		ItemStack itemstack = entity.getItem();
		
		// Noetig damit Item keine Defaulttextur bekommt
		bindEntityTexture(entity);

		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 = itemRenderer.getItemModelWithOverrides(itemstack, entity.world, (EntityLivingBase) null);
		
		boolean forceGlowing = true;
		
		if (forceGlowing) { // FORCE ENTITY GLOWING
			GlStateManager.enableColorMaterial();
			GlStateManager.enableOutlineMode(this.getTeamColor(entity));
		}
		
		Minecraft mc = Minecraft.getMinecraft();
		float playerX = (float) (mc.player.lastTickPosX + (mc.player.posX - mc.player.lastTickPosX) * partialTicks);
		float playerY = (float) (mc.player.lastTickPosY + (mc.player.posY - mc.player.lastTickPosY) * partialTicks);
		float playerZ = (float) (mc.player.lastTickPosZ + (mc.player.posZ - mc.player.lastTickPosZ) * partialTicks);

		float dx = (float) (xPos - playerX);
		float dy = (float) (yPos - playerY);
		float dz = (float) (zPos - playerZ);
		GlStateManager.translate(dx, dy, dz);

		// Groesse aendern! wenn auskommentiert, wird voller Block gerendert
		ibakedmodel.getItemCameraTransforms().applyTransform(ItemCameraTransforms.TransformType.GROUND);
		// Item Rendern
		itemRenderer.renderItem(itemstack, ibakedmodel);
		
		if (forceGlowing) { // FORCE ENTITY GLOWING
			GlStateManager.disableOutlineMode();
			GlStateManager.disableColorMaterial();
		}
		
		GlStateManager.popMatrix();
		GlStateManager.disableRescaleNormal();
		GlStateManager.disableBlend();
    }

 

To add the colored glowing effect, I created a custom team and added the Ghost-Item

 

			Scoreboard scoreboard = mc.player.getWorldScoreboard();
			if(scoreboard != null){
				if(scoreboard.getTeam("Test1") == null){
					System.out.println("create Team");
					scoreboard.createTeam("Test1");
					scoreboard.getTeam("Test1").setColor(TextFormatting.GOLD);
					ghostEntity = new EntityItem(mc.player.getEntityWorld(), 0, 70, 0, new ItemStack(Blocks.COBBLESTONE));
					ghostEntity.setGlowing(true);
					scoreboard.addPlayerToTeam(ghostEntity.getCachedUniqueIdString(), "Test1");
				}
			}

 

The problem is, that if the glowing effect is enabled, the whole Ghost-Item is rendered white.

 

Picture 1: Ghost-Item at a specific location in the world without glowing effect: CLICK

 

Picture 2: Ghost-Item at a specific location in the world with glowing effect: CLICK

 

How can I fix this? The teamcolor is e.g GOLD.

 

Thank you for your help.
