Legacy GM [SOLVED] irandom() issues in Create Event

[TheRBZ]

I've made an obj_tree which can choose a variation out of 4 different sprites (so the object doesn't look repeated) but when I try my code, all trees are the same type.
I can confirm that this is not an issue with the sprite_index applying to all instances* because every time I run the game they are of a variation '0'.

Why is my irandom(3) function always outputting 0?
Yes, the sprites it can choose from are different.

*instances are put in the room manually, only for testing so using the create event per instance won't cut it

Spoiler: Code

randomize();

image_xscale = 2;
image_yscale = 2;

var type = 1;
var variation = irandom(3);

sprite_index = "sprite_tree_big_type"+string(type)+"_"+string(variation);

Resource IDs are not strings, stop treating them like one.

Use asset_get_index() to convert that string name back into a sprite ID, then set sprite_index to it.

sprite_index = asset_get_index("sprite_tree_big_type"+string(type)+"_"+string(variation));

never mind..

asset_get_index

I had no idea that was in gm these days, is it new for gms1 or gms2?

guess it's time to go through the manual again...

Fixed! Thank you.

asset_get_index() has been in GMS 1.x for at least 3-4 years, and in GMS 2.x from day one.
