So…this is my current project, can anybody help me make it so that if 1 person is playing the other characters don’t appear, and that the entity ai will make it move randomly Without phasing through walls, then if it comes in a radius of one the player it start chasing them for like 20 seconds maybe…but It should work for 1 player, 2 players, 3 players, or 4 players thank you!
