hi calewell !
if you use a random for generating the index of the array you read, it will randomize number and often returns the same index, that s why you have actor spawning on the same spawn.what you can do is creating an array of bool, synced to you array of spawner, and set the bool to 1 when the spawn is “occupied” :
for exemple , set the bool array [3] to 1 if spawner 4 is already occupied
and then randomize with the reamining free indexes to spawn next actor.
fell free to download my project here :
i use this method to spawn the bonuses and to prevent to have 2 bonuses at the same point
