So recently I downloaded this level used for a level contest a while back. Looked pretty fun, as it was Super Mario Bros 2 themed so it brought back a lot of fun memories. Anyways, further in the level, you come to a spot where there are three phantos above you and a platform with a key below them. If you don't know what a phanto is, click on this link:
When I grabbed the key, one of them started moving like the ones on the real game, followed me and chased me, was able to go through blocks, and deal damage. I am very sure that it was not a re-textured flying Koopa as you could not kill it.
Tried to recreate what I saw with the movements in the Events layer and whatnot, but absolutely nothing. Is there some sort of checkbox that I have to mark to activate it or how was the level creator able to mimic the flying with minimal event movements?
If this is already a discussion I apologize, but it's been bugging me for a while now and I haven't found any related topics.
