it's strange, i haven't ever done it before.
If a want to create an action that in the first 30 seconds move the object along his x and in the after 20 along z and x, and then in the after 30 seconds roteate etc etc.
How can i do?
create a while like
while(1){
c++;}
while c < 100 move
while c > 100 && < 220 roteate

But it havent the right time.

var t = 0;
while (t < 30)
{
move along x;
t += time_step * 16;
wait(1);
}

while (t < 50)
{
move along z,x;
t += time_step * 16;
wait(1);
}

while (t < 80)
{
rotate;
t += time_step * 16;
wait(1);
}

Hope you get the idea...
