Well you need to find your two points in the world to draw your box. I would probable setup a plane with a collider that represents your ground and raycast from your mouseposition using the camera to ray function ( on phone so can’t look up docs ). Then store the raycast hit point into a vector3 on mouse down then while the mouse is down update you box to draw in world space from your starting vector3 to your current mouse position hit point. Once you define that area all you have to do is determine which Targets are in that area.

Hope that helps.


find mouseposition using raycast
