How to do in c-script?
I've made this:
Code:

---

 Action Spawn2
{	
	my.push=1;
	my.polygon=on;
		while(my)
	{

			you=ent_create(bullet,vector(my.x-40,my.y,my.z),shoot_you);
			you.passable=off;
			wait (3);
	}
	wait(1);
} 

---

Code:

---

Function Shoot_you
{	
...
...
	
   while(my && Player)
	{	
		c_move(me,vector(shoot_speed*time_step,0,0),nullvector,Ignore_Push );
	}

}

---

But tha game crash(black screen), I don't understand where the error is.
Someone can tell me what script should I use?

Something like: if player is near 200 quants to enemy, the enemy create a bullet.

To create enemy bullet when player is come close enough :
Code:

---

var shoot_speed = 5;
var pushValue;

function shoot_you()
{
   pushValue += 0.1;      // prevent bullet hit each other
   my.push = pushValue;   // reset it if reached certain value
   my.skill1 = 100;       // bullet life
   while(my.skill1 > 0)
   {
      c_move(my,vector(shoot_speed*time_step,0,0),nullvector,Ignore_Push);
      my.skill1 -= 1 * time_step;
      wait(1);
   }
   ent_remove(my);
}

Action Spawn2 // enemy action
{
   c_setminmax(my);
   while(player==NULL) {wait(1);}
   while(my)     
   {
       if (vec_dist(player.x,my.x) < 50)
       {
          you = ent_create(bullet,vector(my.x-40,my.y,my.z),shoot_you);
          you.pan = my.pan;
       }
       wait(-0.5);
   }
}

Just an example.

It give me an error, when player die, the engine tell me : empy poiner in Spawn2.
why?

Try modify the following code :

Change while(my) to while(player != NULL)

EDIT

If it still doesn't work, please post your player codes.
