I am instantiating new enemies in waves for the player to battle. After 7 enemies have been defeated, all enemies Instantiated detect a collision with the Main Character's sword even when there is none. How can I stop this? I have checked to make sure that they are not accidentally colliding with the sword, and they aren't, yet Unity is detecting a collision between the two objects.
Are you sure it isn't another object that gives the collision, like the floor or the enemies own weapon? Try adding some debug to find out what the colliding object is exactly.
