I spawn several BP_Wall. It cointains wall mesh, and box overlap all with standard collisions.
Afterwards i spawn BP_Door. It contains another wall mesh, and a box overlap all with standard collisions.
Upon spawn of BP_Door, i have a custom event triggered.
BP_Door(Box → Get Overlapping Actors(Filter Out BP_Wall)) set in a For Each Loop → Destroy actors (Exec comes from Loop Body, and Target is linked in Array Element)
When this runs, only one BP_Wall is removed (2 is overlapping)
but if i before the For Each Loop, runs a ForLoop from 0 to 1, it removes both Walls.
I had this same problem. You MUST save the output of Get Overlapping Actors into a new array and then loop through that new array if you want deterministic results. The foreach actually grabs a new array from a new Get Overlapping Actors call each time through the loop, but increments through the index as if the array were the same as the one it started with.
