hi man,as i told you before make tow separated models as doors and attach them this actions:

action door1_act()
{
while(!ball){wait(1);}
var box_move=0;
while(1)
{
if(vec_dist(me.x,player.x)<150 && box_move<500)
{
box_move+=10;
c_move(me,vector(0,-20*time_step,0),nullvector,GLIDE | IGNORE_PASSABLE);
}
if(vec_dist(me.x,player.x)>150 && box_move>0)
{
box_move-=10;
c_move(me,vector(0,20*time_step,0),nullvector,GLIDE | IGNORE_PASSABLE);
}
wait(1);
}
}
action door2_act()
{
while(!ball){wait(1);}
var box_move=0;
while(1)
{
if(vec_dist(me.x,player.x)<200 && box_move<500)
{
box_move+=10;
c_move(me,vector(0,20*time_step,0),nullvector,GLIDE | IGNORE_PASSABLE);
}
if(vec_dist(me.x,player.x)>200 && box_move>0)
{
box_move-=10;
c_move(me,vector(0,-20*time_step,0),nullvector,GLIDE | IGNORE_PASSABLE);
}
wait(1);
}
}

Like this it crashes, changed player to ball because my player is the ball
And when I started first time, nothing happended... But I'll try it, thakns!

of course it will crashes.

don't forget change word(player)to (ball) in you'r script.
or simply keep it like this and put in you'r ball's action:
player=me.

Thanks Guy, thought I can be clever enough to now use c:move but sometimes if you are too clever you become like a NOOB. Like I was

Okay thanks, works of course
