Simulating Social Force
Mar 17th, 2010, 2:50am  
Hello,

I need to write a program that simulates people movement and I need help. I want to generate several groups of people who will be given different targets. That bit I can do. However, there is another requirement and that is that they cant collide with each other and have to avoid walls and I have no idea how to do that. Please point me in the right direction.

Thanks,

I think this topic belongs into the program rather the syntax section, but one of the modorators will take care, I'd guess....

Anyway: Start out with the "collision" examples of the reference, which should give you an idea of how you can check the "collision" of spheres (or circles) with each other by testing that their minimum distance is not smaller than twice their radius.
For "general" walls it is a little bit more  complicated. If they are only horizontal or vertical, you can check the according coordinates (x or y) rather easy (again check that the position is at least "radius" away).
