I am trying to write a game, and I need some of the objects to avoid
other objects. I didn't want to use a complicated pathfinder, so I am
just using Obstacle Avoidance. I have a problem with my script so
that if the moving object has to go around an obstacle and in doing
so goes around the very top of the obstacle (they are all circles),
it gets stuck. The problem is that it uses the angle to the
destination and the angle to the center of the obstacle to compare,
and sometimes one of the angles are > 270 and the other is < 90, and
it goes the wrong direction. I have posted the stack and you can just
throw this in the message box:
go stack URL "http://revcompgeek.googlepages.com/obstacleAvoidance.rev";
Just right click somewhere and the mover will try to go there.
The code that needs to be changed is in the mover graphic, on the
line that says
if obstangle < tangle then
