Print X, Y on Mouse Click

If that’s a plane in the 3d scene you want the mouse pointer to collide with then there’s this great snippet by rdb, that I use all the time:

Super-fast mouse ray collisions with ground plane

I was shocked to learn that many users do not know about the existence of many useful mathematical classes and functions that Panda provides. Thus, many users use Panda’s collision system if they want to detect where a mouse ray hit a ground plane (for point-n-click movement in a 2d world) etc etc. Thus, I quickly threw this snippet together that shows how to use the Plane class to calculate the intersection point with a mouse line. Super-fast. (Note that there are many more uses to this.) fro…
