Pass Enum To Function Parameter

Question

Hello,

On one script I have a enum variable, and I want to send the enum in a SendMessage as a parameter to another script, like so:

Weapon Object

 // ----- Weapon Pickup ----- \\
 enum selectWeapon {Gun, LargeGun}
 var typeOfPickup : selectWeapon;
 
 function OnCollisionEnter(hit : Collision){
    hit.collider.SendMessageUpwards("changeWeapon", typeOfPickup, SendMessageOptions.DontRequireReceiver);
 }

And on my player

 // ----- Player / Receiver ----- \\
 function changeWeapon(weapon : ???) {
    if(currentWeapon == weapon.Gun){
       //do something
     }

}

Any ideas how I can do this?

Thanks

I tried to make a parameter of type _try(enum) and also int both worked for me. the below is the code. casting it to int would definitely work. Also i remember enum not working properly for if loops on another sciprts (in unity script), so used to follow casting to int method.

   public class enumChecker : MonoBehaviour {
     
     _try obj=_try.blah;
     // Use this for initialization
     void Start () {
         haha ((int)obj);
     }
     
     // Update is called once per frame
     void Update () {
     
     }
     
     void haha(int  temp)
     {
         print((_try)temp);
     }
     
 }
 
 
 public enum _try
     
 {
     lol,
     meh,
     blah,
     rofl,
     lmao
     
 }

You should be able to use selectWeapon as the type, as far as I can see. Is that not working?
