The title really explains it all. I want to see if a position is in the view of the camera. (Please take FOV into account)
Use WorldToScreenPoint.
Description: Takes a 3D world point and returns the following: A Vector3 where the X/Y components map the position in screen coordinates the worldPoint maps to, and the Z component maps how far away from the screen plane the 3d position is (positive if in front of camera, negative if behind). A boolean which is true if the point is visible on the screen or not.
The last part is what you're looking for.
