i’m working to create the first level in ue4, but i tried already to implement this on the udk back in 2011 without good results, that’s why i’m asking for tips to do this. i will post news when the level is done.
You could always add a trigger above a broken brick, that moves the enemy down and freezes them in some way.
Or like Akuma said, change the visibility of the brick and remove collisions from it (possibly adding a small invisibly brick at the bottom, to stop the enemies falls all the way through).
Not sure to what extent you want to recreate it though. Do you want it to look like UE4 physics, or the original fall handling?
