Question by cotterdev · Jun 09, 2021 at 11:52 PM · instantiate terrain

How to restrict where gameobjects can be instantiated on terrain?

I am building a tower defense game. How can I limit where the user can place turrets? In the attached photo, I would like to allow the placement of turrets on the edge of the path but no where else.

I thought about putting a collider along the path, but I plan on making a another level with a winding path. Putting a collider on a winding path would be quite cumbersome. Any ideas on how to make this work? alt text
