Hello,

 

I already asked this question a while ago for 1.15, but I think I can ask more specificially now. 

I want to implement a falling star similar to the one in the LegendGear mod. So it's basically a ProjectileItemEntity falling from the sky but overlayed with a spinning, color changing star-shaped texture.

I already implemented the entity and it works fine, but I struggle with the renderer. I looked at the SpriteRenderer to get some information on how to use MatrixStacks and so on and this is what I currently have:

	@Override
	public void render(ShootingStarEntity entity, float f1, float f2, MatrixStack stack, IRenderTypeBuffer buffer, int i1) {
		super.render(entity, f1, f2, stack, buffer, i1);
		IVertexBuilder builder = buffer.getBuffer(RenderType.getCutout());
		if(!entity.collidedVertically) {
		}else {
			stack.push();
			stack.rotate(this.renderManager.getCameraOrientation());
			stack.rotate(Vector3f.YP.rotationDegrees(180.0F));
	    		this.itemRenderer.renderItem(entity.getItem(), ItemCameraTransforms.TransformType.GROUND, i1, 0, stack, buffer);
	    		stack.pop();
		}
	}

(The renderItem call has currently no further use)
And this code is, as far as I got it basically used to make the ProjectileItemEntity (e.g. snowball) appear and look at the player.

My texture for the overlay is just a white, star-shaped texture with some transperancy.

I hope someone can give me a hint on how to overlay a texture and how to rotate and color it. I found many methods in many classes, but I don't know which to use here.

 

Thank you in advance and stay healthy

If this is a texture for an item (as it seems to be), you could easily animate it using an mcmeta and change the colors within the texture itself or using ColorHandlerEvent$Item. If that's the case, then you would just need to register the factory with the SpriteRenderer instead of recreating it. If you wish to stay on your line of thinking, you will most likely have to reconstruct the ItemRenderer methods with some additional parameters in the correct RenderType.

Not exactly. The texture for the item shall be handled as always and then I want to add a layer with another texture with the things mentioned above. 

But I guess the things you told me should help, so I'm going to try it. Thank you for now - I write again, if I have more problems

To clarify what I mean:
