I am trying to draw an image for every bullet left in my magazine variable. I tried to use the action_draw_life_images function, but I don't know the syntax. Nor do I know if I am able to input a different variable other than lives. I would be very thankful for any help resolving this.

just do this:

if var  = 5
  draw_sprite(bullet,0,x,y)
if var  = 4
  draw_sprite(bullet,1,x,y)
if var  = 3
  draw_sprite(bullet,2,x,y)
if var  = 2
  draw_sprite(bullet,3,x,y)
if var  = 1
  draw_sprite(bullet,4,x,y)
if var  = 0
  draw_sprite(bullet,5,x,y)

Then with the button you use to shoot with:

var -= 1

Thank you, this did work, but is there any better way that takes up less memory. Such as some sort of function I can use?

Oh...sorry. Try this:

draw_sprite(bullet,var,x,y)

then just use the same code for the button

Oh...sorry. Try this:

draw_sprite(bullet,var,x,y)

Nope, this didn't work. Oh well, I'll just do it the long way. Thank you very much for helping me.

no prob

I just had a really good idea. Maybe I could try and do an assignment operator and just be like for every instance in the variable add 1, then add a multiplyer for how many pixels I want in between.

[Popcorn123]

you can try

[trivettz]

you can try

I found something about for statements on oracle's website and used that. The code ended up being:

for (pixel = 0;
pixel<global.clip;
pixel += 1)
{
draw_sprite(sprite1,-1,8+(pixel*8),64)
}

Oh! I forgot to mention that it worked.
