Hello,

I am trying to use the method rayTraceBlocks to see if my block can see the bottom of the world, however after approximately 11 Blocks of height (I say approximately as the distance has changed from time to time) the detected collision shifts 1 Block to the center of the world. If my block were for example at the position x: 4 y: 77 z: 0 the collision would be detected at x: 3 y: 55 z: 0 shifting 1 Block in the direction of the world center.

This is the Code of my raycast (-100 is just a test value):

Spoiler

@Override
	public void update() {
		if(!world.isRemote) {
		RayTraceResult result = world.rayTraceBlocks(new Vec3d(pos.getX()+0.5, pos.getY()-1, pos.getZ()+0.5), new Vec3d(0, -100, 0), true, true, true);
		if(result!=null) {
		BlockPos bpos = result.getBlockPos();
		System.out.println("Blockpos: "+bpos.getX()+" "+bpos.getY()+" "+bpos.getZ()+" from: "+pos.getX()+" "+pos.getY()+" "+pos.getZ());
		}
		}
	}

 

 

Thank you for your help!

Why not just use a loop going down towards zero or a mutable Block pos?

I have used that for another block, I just wanted to try using raycasts once, however maybe it isn't the right application.
How performance heavy are raycasts compared to just checking the blocks one by one ?

Extremely, just compare the code in the method that you’re calling to a simple  loop

Well okay then I'll just use the loop. Thank you very much!
