I've a sort of problem with wait and a while loop
Code:

---

while(my)
	{
		my.x -= 3* time;  
		  if (my.x < -3600)
       {
             my.y += 10*time_step;
             if (my.tilt <= 15){
             my.tilt += 5*time_step;
             }
             ent_create(bullet1,vector(my.x-20,my.y,my.z),move_bullet1);
             wait(10);
       }
       wait (1);
	}

---

This is a ship, it moves and when is .x is smaller than -3600 start fire and move towards y.
Cause of the wait the ship doesn't move quikly.
I've tryed to divide the while loop and create 2 different, but that's the same thing.

how to do?

Kind of strange function,
but the main thing you should change is to never use wait(10);
this waits 10 frames, and not a specific time, use the negative number like wait(-0.1); or so
for time in seconds. (is like sleep() function)

var fps_max=120; //limiting the framerate an fast computers

...

while(my)
{
my.x -= 3* time;
if (my.x < -3600)
{
my.y += 10*time_step;
if (my.tilt <= 15){
my.tilt += 5*time_step;
}
ent_create(bullet1,vector(my.x-20,my.y,my.z),move_bullet1);
wait(-1); //or another value, that is not framerate dependent
}
wait (1);
}

ah, I see, but the problem isn't this.
Cause the wait is in the while and must be after the ent_create(a bullet for 2 seconds for example), the ship moves like: +10 stop +10 stop.
Sorry my bad english, I can't explane myself better.

var tempa;
while(my)
{
my.x -= 3* time;
if (my.x < -3600)
{
my.y += 10*time_step;
if (my.tilt <= 15){
my.tilt += 5*time_step;
}
int(tempa);
if(tempa == 8)
{
ent_create(bullet1,vector(my.x-20,my.y,my.z),move_bullet1);
}
tempa += 1;
tempa %=9;//must be one higher then the one in the if(tempa,enz.
}
wait (1);
}

change tempa the red parts for longer ore shorter

Thx a lot!
It work, but I don't understand how.
There are a var int, and...
°A°

the int cuts evthing after "," so 33,23 woulde be 33 dont know if its necery
tempa += 1; ads 1 every frame
tempa %= 9; if(tempa == 9) tempa = 0
