Hi all,
I’m having a problem that I cant solve for literally days. I have a bullet with a script that when it collides with an enemy with the tag “Enemy”, it should get the DealDamage from that gameobject (the enemy) with the EnemyHealth script.
I’ve done this before in the past but when im doing the same thing now, I keeps giving me a “NullReferenceException: Object reference not set to an instance of an object” error. I think it should mean that it cannot locate the script that its searching but its not there… but it is? Its giving me a headache!
Please help me 
It gives me the error on line 38.
