managed to attach the sprite to the desired vertex, and i get the angle (had to correct it gith -90, as you said grimber).
however the sprite's centre is attached to the vertex, but I need the middle of the left edge to be attached.. help me please.
Code:

---

//entities
entity* podL;
entity* podR;
entity* lightning;

//vars and vecs
var vec_pos1[3]; //left pod
var vec_pos2[3]; //right pod
var vec_direction[3]; //from left to right
var lightangle[3];
var dist;

//actions
action pod1{
	podL=my;
	my.material=poddy;
	my.transparent=off;
}

action pod2{
	podR=my;
	my.material=poddy;
	my.transparent=off;
}

action sprite{
	proc_late();
	lightning=my;
	my.bright=on;
	while(1){
	my.frame += 2*TIME_STEP;
	my.frame %= 55;
	vec_for_vertex (vec_pos1,podL,1220);
	vec_for_vertex (vec_pos2,podR,1219);
	dist=vec_dist (vec_pos1, vec_pos2);
	vec_set (vec_direction, vec_pos1);
	vec_sub (vec_direction, vec_pos2);
	vec_to_angle (lightangle, vec_direction);
	my.x = vec_pos1.x; //--->what to add here?<---
	my.y = vec_pos1.y;
	my.z = vec_pos1.z;
	my.pan=(lightangle.pan +90);
	my.tilt=lightangle.tilt;
	my.roll=-lightangle.tilt;
	wait(1);
}
}

---

PS: the angle values just work as posted, dunno why it is that way...

maybe try
Code:

---

my.x = (vec_pos1.x+vec_pos2.x)/2;
my.y = (vec_pos1.y+vec_pos2.y)/2;
my.z = (vec_pos1.z+vec_pos2.z)/2;

great, thanks! a shame, we had this in maths classes half a year ago, and i could not remember it... thanks anyway!

"proof" ^^ (just look at the lightning; pods are without mats settings, looks pretty like nothing, but stay tuned, i will add some gr8 normal maps)

oops! hehe i totaly forgot they moved the origin point of sprites ( im still use to the older way where it was centered alogn the bottem edge

looks ok though with Filipe's fix
( you could use vec_lerp as it does the same thing in one line)

vec_lerp(sprite.x,vertex1.x,vertex2.x,0.5);

hope to see in in action sometime soon

Oh don;t forget, if your pod is moving then you will have to run all these things in a loop, since everything is moving the sprite has to keep up:)

Code:

---

function slim_saber_func()
{
	proc_late();
	my.scale_x = 0.5;
	my.scale_y = 0.5;
	my.scale_x = 0.5;
	my.flare = off;
	my.transparent = on;
	my.bright = on;
	my.passable = on;
	my.alpha = 100;
	vec_for_vertex (pos01 ,slim_core_ent, saber_vec01);
	vec_for_vertex (pos02 ,slim_core_ent, saber_vec02);
	vec_to_angle (my.pan, pos02);
	my.x = (pos01.x+pos02.x)/2;
	my.y = (pos01.y+pos02.y)/2;
	my.z = (pos01.z+pos02.z)/2;
	while(my.alpha > 0)
	{
		my.alpha -= 80 *time;
		wait(1);
	}
	ent_remove(me);
}

how would i fix this to pan toward the second vector?
also how could i do collision?

can anyone help?
