Given a point and a polygon, check if the point is inside or outside the polygon using the ray-casting algorithm.. A pseudocode can be simply: count ← 0 foreach side in polygon: if ray_intersects_segment(P,side) then count ← count + 1 if is_odd(count) then return inside else return outside Where the function ray_intersects_segment return true if the horizontal ray starting from the point P . Alright sorry guys for spamming this post, but I finished up the raycasting method, you can get it here on pastebin because it is 316 lines queryTriggerInteraction: Specifies whether this query should hit Triggers. Int32. If the Ray hits any collider or a physics object like a Rigidbody, we can fetch information about the Hit object. To learn more, see our tips on writing great answers.
