Had trouble googling if this code exist, I need to reference a sprite but a specific point of it.
So my attempt was:
image_index = spr_unit_form1(x+14,y+5); but this is an error, what is the proper way to write this?
(google wasn't helpful)

Image index sets the instances Sprite to be on that image of the Sprite. So setting it to 0 sets the instance to the first image of that sprite. What exactly are you trying to do with this specific point?

well, I was trying out a round-about way to do unit formation. Make a sprite(dots) of how I want the unit to look, then take each soldier and have them AI-path there way to the points.(wasn't sure how to reference pixels in code) There's probably a hundred better ways to go about this, I'm just trying things cause as long as I've used GM, I only vaguely understand how things work.

You could do it with ASCII art.
Create a string like this:
Code:
formation =
"..#..#..#..#.."  +
".............."   +
"#..#..#..#..#."
And then use the string functions to determine what goes where depending on what character is where.

It should be far more efficient, both on CPU and ram.
