hello,
I tried a lot around and I'm not able to solve this problems.
The first one is a little function that _should_ spawn entities in one line from one position to another one.

Code:

---

unction felsSpitzen(VECTOR* startPos,VECTOR* endPos)
{
	VECTOR tempPos;
	VECTOR addPos;
	vec_set(addPos,endPos);
	vec_sub(addPos,startPos);
	vec_normalize(addPos,50);
	vec_set(tempPos,startPos);
	while(vec_dist(tempPos,endPos)>25)
	{
		ent_create("felsen.mdl",tempPos,felsMoveOut);
		vec_add(tempPos,addPos);
		wait(-random(0.05));
	}
}

---

it spawns them correctly, but it don't stop spawning them, if they reached the end-position.If i comment out the wait() everything works property.

My second problem is, that a function(main) I use to check if a key is pressed is closed if I call another function.
I left out all unimportant parts. If I comment out the ent_remove everything works fine.
Code:

function flash_func()
{
	set(my,BRIGHT | TRANSLUCENT);
	my.alpha = 100;
	while(my.alpha>0)
	{
		my.alpha -= 7*time_step;
		wait(1);
	}
	ent_remove(me);
}

function spawn_flash(VECTOR* position)
{
	me = ent_create("lightning2.tga",position,flash_func);
}

int main()
{
	[...]
	while(1)
	{
		if(key_l)
		{
			spawn_flash(nullvector);
			while(key_l){wait(1);}
		}
		wait(1);
	}
	return 0;
}
