Hi

I'm trying to highlight a chunk with a client side mod but I don't understand how can I do

I know NEI already done something similar when you press F7, it show where mob can spawn but I don't understand its code.

 

Could you help me ?

What event should I use ?

Thanks

Using NEI, if you press F9 it will highlight chunks.

I've successfully used RenderWorldLastEvent and then used the tessellator to draw a wire frame or similar.  You just need to draw relative to the player's position i.e. EntityPlayer.getPosition(partialTick);

 

So - if the player is at x = 23.5, and the chunk you want to render is from x = 64 to 80, then your wireframe renders from x = 40.5 to 56.5

 

You will need to understand how to register Forge Events and how to use the Tessellator.  Do you know how to use those?
