I don't even remember making that complicated string.
Here is something using that to grab the name from the Instance variable, and then use that same number to set the frame number of a spawned sprite.
edit: to those wondering what it is without downloading, it's still one event, just more actions and a global variable to hold the random choice for more uses. It still uses the instance for the list of loots, which match up to the frames of the loot sprite.
I suppose I could have made each Loot an animation and named each animation to match the name, and called them by name, but I didn't think of that until writing this.
