Get a gun off a wall

2 scripts:

GunHolder.js

//Attach to a empty, create a working collider for the empty //Parent the gun to the empty and set it as the currentGun of the empty //Tag it as "WeaponHolder" var gun : GameObject;

SwapGun.js

//Attach it to a empty, create a working trigger, parent it to your player private var touchedWeaponHolder : GunHolder; var currentGun : GameObject;

 function OnTriggerEnter( other : Collider ) {
     if( other.gameObject.CompareTag("WeaponHolder") ) {
        touchedWeaponHolder = other.gameObject.GetComponent("GunHolder");
     }
 }

 function OnTriggerExit( other : Collider ) {
     if( other.gameObject.CompareTag("WeaponHolder") ) {
        touchedWeaponHolder = null;
     }
 }

 function OnGUI() {
    //Change display depends on touchedWeaponHolder
 }

 function Update {
     if( Input.GetKeyDown(KeyCode.2) && touchedWeaponHolder ) {
        //(Incomplete Code) You can do 2 different t$$anonymous$$ngs here:

        // - Grab new gun, and keep your old gun in the inventory
        Keep(currentGun);
        currentGun = gunHolder.gun ;
        Destroy( gunHolder.gameObject );

        // - Swap new gun with old gun
        GameObject temp = currentGun;
        currentGun = gunHolder.gun ;
        gunHolder.gun = temp;

        //You can put the change-gun codes here or in the GunHolder.js, up to you
     }    
 }
