code:
  
ACTION terrain {
// Hier das ganze notwendige Zeug
WHILE(1) {
if(vec_dist(my.x,camera.x) > 1000) { my.invisible = on; }
wait(1);
}
}
Vielleicht solltest du statt der 1000 eine Variable nehmen, dann kannst du das "dynamisch" schalten...

Perhaps this post will get me points for originality at least.
