Physics.Raycast

… wow, they named their raycast something besides raycast? ._.

No,like this photo.[10378-qq截图20130424140443.png|10378] The positions of object A and Camera B are known, how to get C point position?

 –

raycast. -_- Ray ray = new Ray(); ray.origin = A; ray.direction = B - A; RaycastHit hit = new RaycastHit(); if ( Physics.Raycast(ray, out hit) ) { C = hit.point; } You might need to use "Layer Masks" to make the ray only be able to hit the ground.
