@Maxxx thanks for rep!
I want them to get through to each other, but able to detect when bodyA comes into bodyB’s position. how could I do that?
sorry my english so bad
Joseph beat me to it - and he’s right. A sensor detects collisions but doesn’t act on them - so setting the IsSensor property to true, and the bitmasks so that they will collide, will give you what you’re after.
