is there a way to have enemys randomly spawn on camra view like how pokemon go randomly spawns pokemons on camra view plus it needs to be diffrent and get rewards from it.
pls help answer my question or give a comment of what you think
Hi there,
yep there is always a way, just the matter of time it takes based on preparation and XP.
The easiest way to communicate the solution to you would be a full sample of your game that would explain you how to implement it. I think you understand what you are asking for 
In this case you are good with watching UE tutorials to learn how to spawn actors and how to randomize vectors
So if you enter the UE dungeon to fight your Level3 boss idea we can provide you with the weapons to farm XP to level you up, instead of spending our time to hunt down the boss for you
For XP farming some short, compact, non exhausting clips from UE channel (no need to watch all of them but the more the better):
Your Level2 Boss: Fun with Blueprints : Spawning Dynamic Objects
Then you should be prepared for your Level3 boss (core basics of your idea). And if not, everyone is happy to help in here if you allow us to offer more precise answers by more precise technical questions (particularly with screenshots )
happy fighting, Marooney
