I'm stuck

So... I tried several tutorials, even purchased paid courses. I'm stuck.

Good things first: I found a YT channel where a slavic genius explains better practices and it helped me finally find out what was causing Lvl005 to become so sluggish. Long story short: too many functions with very poorly implemented logic overwhelmed the memory.

Long rant: delay nodes + embedded replicated logic + no logic for failed interactions when 2 alternative keys open the same door would cause the 2nd key to get stuck in a loop trying to open a door that was already open. All of this overwhelmed the memory becuase in level 5 there are 20 pickups, 5 teleporters, 8 doors with 5 keys, all of those executing failed logic in a loop whilst constantly stopping each 0.2 seconds with the delay nodes.

Current state: Drone enemy AI is barely working as intended, I made a change in the pickups and now the logic is busted so they will activate whether the player or the enemy passes on top of them, so I need to change the logic again so it only interacts with Player but that means coming back to "Cast to BP_FirstPersonCharacter" which is horribly taxing for memory even in this small scale of a game because each pickup has a replicated First Person Character logic embeded into them always loaded in memory even if the pickups only uses the collission detect component.

Conclussion: I'll keep at it but Imma be a dad soon and I'm working a lot lately so I don't have that much time as I would like to, but is a hobby and I enjoy it so I'll get there eventually.
