9,844 PointsWhere to place trigger?
In a game where you will be interactive with many different game objects like NPCS, Trees, Walls and Enemies. Why put a trigger on each of them where you can just place on the player and have the code in place. Or is the fact the code would be in place that is bad practice because it decreases readability?

Treehouse TeacherHi Ranvir,
Anything that interacts with physics needs, at the very least, a physics collider component (such as a sphere collider, box collider, and so forth). This includes the player character and anything you expect them to collide with. If a wall or a tree doesn't have a collider, then the collider on the player character won't know if an intersection has occurred.
While it's possible to use the 3D mesh to detect collisions, this is extremely computationally expensive. It's far better to make primitive approximations (like boxes and spheres) that can be calculated quickly by the phyiscs engine. Hopefully that makes sense!
