I'm experimenting with muzzle flash sprites.
I have this script now:

Code:

---

function muzzle(){
	var tmpx = random(0.3)+0.5;
	muzzle_pan.scale_x = tmpx;
	muzzle_pan.scale_y = tmpx;
	muzzle_pan.pos_x = (screen_size.x - bmap_width(muzzle_pan.bmap))/2; 
	muzzle_pan.pos_y = (screen_size.y - bmap_height(muzzle_pan.bmap))/2;
	muzzle_pan.flags = VISIBLE | OVERLAY;
	wait(-0.05);
	muzzle_pan.flags = 0;
}

---

I also have a center screen screen script, the 2 longer lines of coding.
But the center screen script doesn't work on my random resize script, hoe can I make it so that the muzzle always displays in the center?

That's the exact same formula I use to put a crosshair in the center of the screen, and mine works fine. What's going wrong, specifically?

EDIT: oops, saw it right after I posted...Try this:
Code:

---

muzzle_pan.pos_x = (screen_size.x - bmap_width(muzzle_pan.bmap) * tmpx) / 2;
muzzle_pan.pos_y = (screen_size.y - bmap_height(muzzle_pan.bmap) * tmpx) / 2;

---

bmap_width and _height always give the size of the original image, not the scaled panel.

Thank you very much.
Working fine now.

Another question, is there also a script to find out the width in pixels off a Text panel, so I can center text panels on screen?

Actually, with texts you don't need to know the width; the CENTER_X and CENTER_Y flags do this for you. Just make sure pos_x and pos_y are in the center of the screen (screen_size.x / 2, screen_size.y / 2).
