OnControllerColliderHit -> GetComponent on collided object not working

Questions & Answers
1

I have been researching this for 6 hours. Slept on it, another 2 hours and still no luck. I have never felt so defeated; this problem has to be something so simple and stupid! Here’s the skinny:

I have a player GO that is a modified CharacterController (“Player”). It is the parent of a small sphere GO that has a SphereCollider on it (“Weapon”). Any time I try to collect the Enemy script from collisions, I pop 3 generic errors.

I am testing collisions against a Cube primitive that has a BoxCollider and a Rigidbody (“Enemy”). It also contains a script (Enemy.cs) with the basic badguy functions.

Codewise on the Player (parent, CharacterController):

 private Enemy enemy;
 void OnControllerColliderHit(ControllerColliderHit hit) {
		if (hit.gameObject.tag == "Enemy") {
        	enemy = hit.gameObject.GetComponent(Enemy);
			enemy.TakeDamage(25);
		}
     }

I have also tried:

void OnControllerColliderHit(ControllerColliderHit hit) {
       hit.gameObject.GetComponent(Enemy).TakeDamage(25);
     }

Throws these errors on the line where I try to GetComponent():

  • Error CS0119: Expression denotes a
    type', where a variable’, value' or method group’ was expected
  • Error CS1502: The best overloaded
    method match for
    `UnityEngine.GameObject.GetComponent(System.Type)’
    has some invalid arguments
  • Error CS1503: Argument #1' cannot convert object’ expression to type
    `System.Type’

I get the same errors also trying OnCollisionEnter() attached to the Weapon GO. I learned that the Parent GO has to handle collisions for its children, which led to dropping the OnControllerColliderHit() onto the Player.

Thanks for taking the time to read this. I appreciate any help you can offer. I’m thinking about just not worrying about collisions between the Player and anyone else, un-childing (bastarding?) the Weapon GO and then just enabling it around the player during its animation so it can handle its own collisions.

You need to GetComponent(typeof(Type)). It’s weird, yes.

You can also GetComponent< type >.

In unityscript, GetComponent(Type) works fine because it’s overall a very lazy language. I mean you don’t even have to explicitly cast every single set of digits to float! xD
