Question by brawler93 · Apr 14, 2019 at 01:17 PM · unity 2dpathfindingdrawingnodes

How to draw a filled rectangle through script

Im trying to make a A* pathfinder for a maze. Im doing this with nodes(each square in the maze is a node). Now for debugging reasons I want to give certain notes different colors.

I want to do something like.

Why don't you just make a quad prefab and scale it to size. Have a couple of materials that have different colors and apply the material based on the color you need every case? Just an alternative that I think might save some time here.

Was thinking about that aswell yes. Might be the way to go since it only for debugging anyway. thx

Have a look at the OnDrawGizmos callback as well as the Gizmos class. If you're working in the X-y plane you could use Gizmos.DrawGUITexture. If you work on different axes it's probably simpler to just use Gizmos.DrawCube.
