for the particles, I have the code somewhere...

(note: you need at least commercial for the streak effect to work)

Code:

---

function delete_line()
{
	if(my.alpha < my.skill_a && my.skill_c == 0)
	{
		my.alpha + = 20*time_step;
	}
	else
	{
		my.skill_c = 1;
		my.alpha - = 2*time_step;
	}
}

function line_red()
{
	my.bmap = red_line;
	my.move = off;			//important!
	my.streak = on;
	my.alpha = 0;
	my.bright = on;
	my.transparent = on;
	my.size = .75;
	my.skill_a = 7;
	my.function = delete_line;
}


//careful: the vectors you pass to this function have to be global vectors...
function draw_red_line(&vectorfrom,&vectorto)
{
	vec_diff(temp,vectorto,vectorfrom);
	effect(red_line,1,vectorfrom,temp);
}

Hope it helps...
