Hi,
When i have my mousecursor at the screen. I can use the direction to send a trace. But how can i determine if my line cuts a plane?

For this specific situation:


Iam looking at my surface made out of different cubes(atm).
Now i need to calculate which cube is below my cursor to select it. Since i might consider using a single mesh later, i cannot use something like SHOOT. i need to calculate the point where my cursor trace hits the same plane as my surface.
Bets ist, if its entity independend.

Maybe someone has an idea?

EDIT: since all of my blocks are aligned on my grid, i just need the global position to calculate the required block.
