I have a box with 4 walls in the centre of the screen.
Inside the box i have 10 marbles.
I have applied physics to all marbles. The walls are set to unmoveable.
I can move the marbles with the mouse as I enabled Drag & Drop on the marbles and they react great. however if i apply a large impulse or move the mouse a lot, the marbles PASS THROUGH the walls.
I wand to make the walls HARD and IMPENETRABLE. What physics attributes should I apply to the walls?
Thanks a lot
