Legacy GM (Solved) Is there a way to count the number of sprites in a game?

[jb skaggs]

How would I go about counting the number of sprites in a game and then sort them into groups?

lets say I have 500 sprites- but I need to find out how many are floor sprites versus weapon sprites?

i'd assume I would name the sprites:

sprite_floor0
sprite_floor1
sprite_weapon0
sprite_weapon1 etc

1: how does one get the total number of sprites?
2: What would be the best way to store and group the list? As a ds_list?

Thanks
JB

Look in your project folder in windows. Also there is a program out there somewhere (google it) called GMPal.exe which can tell you stuff like this as well as give you some nice search and replace features.

Thanks for the response, but I not sure I made my self clear.

The reason I ask, is I want to be able to dynamically create objects based on the number of sprites, and the number will change as the sprites are loaded or deleted/

I didnt read whole text and I miss understand you so if you read it my frst post ignore it. I would make obj_counter and in it I would put variables sprite_1 , sprite_2. In the objects that have sprite_1 in create I would put obj_counter.sprite_1 += 1 (so every time there is object with sprite_1 obj_counter will know it) and also I would put in on places in code where it changes sprite or die obj_counter.sprite_1 -= 1 . So if you need variable that needs to know how much are sprites of that tipe you just write what_ever_your_var_is_named = obj_counter.sprite_1 . I hope you get it

Yes, via asset_get_index and sprite_exists.

var run = true;
var i = 0;
while (run) {
   var ind = asset_get_index("spr_weapon" + string(i));
   if (sprite_exists(ind)) {
      ds_list_add(weapons, ind);
   }
   else {
      run = false;
   }
   i += 1;
}

As for getting the number of sprites, use ds_list_size.

@Ragarnak -- isn't that only going to work as long as sprite index 0 is a weapon?
He'll probably need to grab all sprites, then go through separating out ones named spr_weapon

I don't see why that would happen. Since he's going to name his sprite this way:

spr_weapon0
spr_weapon1
spr_weapon2
......
spr_weapon99

...I form a string by combining `spr_weapon` with a number (starting at 0), then use asset_get_index to get its index. If such a sprite exists, its index is returned, so sprite_exists returns true and the index is added to the list. If it doesn't exist, -1 is returned which causes sprite_exists to return false, thus setting run to false as well and the while statement ends. If it doesn't end, i is incremented and the process repeats itself. But I might be missing something, so let me know why you think of it that way.

He'll probably need to grab all sprites, then go through separating out ones named spr_weapon

Yes, that's an option too. Possibly the best choice if he decides to use clear names for the sprites, such as `spr_weapon_knife` and `spr_weapon_gun`. He could use sprite_get_name with string_copy for each index, then compare it with `spr_weapon`.

Hey you guys are angels! Thanks for the help! I'll try it and see when I get home from work.

It worked like a charm
