Legacy GM Filter out image_indexes within an object

[CinnaBrynn]

So, i'm creating a list that contains 5 image_indexes of an object's sprite_index so I can filter them out from the rest. Is there a way to do that within an object?

You're already doing it in an object. What exactly are you asking for? lol

The sprite that is attached to the object has 28 images. I have written code that allows me to choose up to 5 images of my choice to put into a ds_list. My issue is, how do I only display the 5 images that I chose from the list.

Instead of having the object draw itself, you'll want to draw with code, and keep track of image_index yourself.
Suppose you have this in the Create event:

current_image = 0;

myList = ds_list_create();
ds_list_add(myList, 0, 3, 5, 8, 17);

You could now do something like this in the Draw event:

current_image+=1;
if( current_image >= ds_list_size(myList) ){
     current_image = 0;
}

draw_sprite( sprite_index, myList[| current_image], x, y);

That code loops from zero up to the size of the list, and uses the numbers in the list as the sub images to draw.

Of course, this will cause the animation to play 1 frame per step, too. If you want it slower, you'll have to accommodate for speed, too. Simple method:

current_image+=numberSmallerThanOne;
if( current_image >= ds_list_size(myList) ){
     current_image = 0;
}

draw_sprite( sprite_index, myList[| floor(current_image)], x, y);

I've incremented the current image by a fractional amount, so it takes more than one step to go up by 1.... and then used the floor() function to round it off when drawing.

That makes sense! Thank you!!
