I’ve worked tons with Handles and Debug and Gizmos for debug lines in the Scene view, but for this project, I’d like to have it display a grid of lines for me to play stuff in the game editor.
What’s the best way to do this, or the best set of functions to use?
I have to say, the “best way” for the fewest headaches would be to get your hands on Vectrosity from the Asset Store. For the price, you just cannot beat it.
Alternatives are using OpenGL directly, creating a Mesh at run-time, or using the Line Renderer class.
