Hello all, I am making a small MOBA game in which the main player attacks enemy with a fireball and enemy health decreases.
The problem I am facing is that when I am throwing fireballs, the main player's health is also decreasing. I have added collider on both fireball and player, and on enemy have called OnCollisionEnter() on player script as I am changing the tag of other player to 'Enemy' once both are in network.
I tried to shift spawn point ahead of the player but still this is the issue. You can see the script, this script is used across the network.
