making a wire loop game ,
i have been struggling all day to make the collision between the ring and the loop work , please can anyone do a test file and show it to others so we learn more about collision , thanks .
btw : what is the difference between collision and touch in the game engine ? , i know about the material and property thing , but is one more precise or something, i have never used touch before !!
help please .
You need to set some sort of bounds, otherwise the default is box, which won’t work.
I set the ring to a dynamic object with damping all the way up. I changed its bounds type to triangle mesh, and set gravity to none.
I added a property to the wire named “loop”, and added a collision sensor that detects when it touches the loop. It ends the object and adds an overlay scene. I’ve attached the file.
Also, I applied scale and rotation to both objects, otherwise the collision would be messed up also. (ctrl+a)
To be honest, I don’t know the difference between touch and collision either. I’ve always used collision, but I don’t know why.
