Ah, a beginner. K, well, collision in alice is known to be (very bad). We have created several collision programs all over the threads to help with your games. If you want to do the simple but not very reliable way of collisions that alice has. Make an event thats a while something is true. Select the world object and go to functions in the list of options on the bottom left. You should find near the top a button that says, "if "object" is within --meters" or something like that. Drag that in the "true" section of the event for the while something is true and set a distance. then in the begin, during, and end section, say what you want to do. Depending on how fast your going of how far your going to move backward. Always set the duration to "0 seconds" for most reliable collisions. Experiment a little with the speeds and you can change the collision camera move back speed or what ever object is moving. Hope i helped, and questions please ask.

This is brilliant! Do you mind if I use this in my project, it is the only collision detector that will work.
