using random in an array

i am trying to set up an array of positions. on these positions random object should spawn. after aobject spawned on one of these positions, the posiiton should be removed from the array, so that no other object spawns on the same position. how can i achieve this?

this is what i got so far, but the objects keep spawning on the same position…-


Maybe im crazy but im pretty sure this aint UEFN

oh yes thanks, wrong forum
