I have a bunch of AI units that follow a main charecter around, however in doig so they all eventually line up on each other makeing them appear to be olny one object.. which in turn looks bad. I have tried a number of ways to fix this and it won't work. I eaven took the collision code from the fps turorial and eaven that diden't work. would some one please help me.

There is an RPG Engine in yoyogames by Yal which has the solution of your problem. It is basically an RPG engine but it has the AI that you want.

One way would be to make them be able to collide into each other, like solid objects

I did on way, when they follow the hero, use the mp_potential_step function:

mp_potential_step(x,y,stepsize,checkall)

x,y - the coordinates to move towards. to follo w an object: object_name.x, object_name.y
stepsize i thnk it's like the speed
checkall - true/false. if true it will try and avoid all objects, false will only check for solid objects.



You can put true, or make all your AI solid and put true for checkall.

This is just one way to do it :P
