Spawning Actors from an Array Causes a Crash

Got it. I needed to use SpawnActorDeferred instead of SpawnActor. Not really sure why. I think it’s because I construct the Actors elsewhere, before spawning, but idk where. Whatever…

Correct code:

void AEnShips::mySpawn(int x, int y, FVector pos, int size)
{
	if (size == 1)
		swarm[x][y] = ()->SpawnActorDeferred<ASmallEnemyShip>(ASmallEnemyShip::StaticClass(), FTransform(pos), nullptr, nullptr, ESpawnActorCollisionHandlingMethod::Undefined);
	else if (size == 2)
		swarm[x][y] = ()->SpawnActorDeferred<AMedEnemyShip>(AMedEnemyShip::StaticClass(), FTransform(pos), nullptr, nullptr, ESpawnActorCollisionHandlingMethod::Undefined);
	else if (size == 3)
		swarm[x][y] = ()->SpawnActorDeferred<ABigEnemyShip>(ABigEnemyShip::StaticClass(), FTransform(pos), nullptr, nullptr, ESpawnActorCollisionHandlingMethod::Undefined);
	else
		swarm[x][y] = ()->SpawnActorDeferred<AEnemyShip>(AEnemyShip::StaticClass(), FTransform(pos), nullptr, nullptr, ESpawnActorCollisionHandlingMethod::Undefined);
	if (swarm[x][y]){
		swarm[x][y]->x = x;
		swarm[x][y]->y = y;
		swarm[x][y]->SetActorLocation(pos);
	}
}
