Register early Ceiling hits before the real hit.

Im making a simple Mario platformer with real physics.
I want to be able to see if Mario will collide with a specific object immediately when Mario is jumping
since I know Marios jump path. (parabel function).

I don't want to use simple collision/trigger handling to solve this problem since colliders will be disabled / enabled depending on if Mario will hit a specific object. And Im guessing its better to calculate if Mario will hit the roof One time instead of checking every frame. (can be between 15-40 frames before the hit really occur.)

But in short I want to be able to know if Mario will have a future hit in the ceiling given that I know start velocity,acceleration, mass ,position as well as the specific object position. Would be very happy if code is shared as well!!

 

Would be great if a moderator could move this problem to the Physics forum
