The wolf BP, make an int in there. Set it to 0 for the first wolf. That wolf will save location in index 0 of the location array, and 0 of the health array.
Same for 1, and 2 etc.
If you have already put the wolves in the level, just set the ID on each wolf.
If you’re spawning wolves, you need to get each one an ID as you spawn it, and it will put itself in the right location, with the correct health.
