Weapon PickUp

Unity Engine

Hi. I’m having trouble with weapon pick up .I made so far when i collide with weapon collider it shows GUI , and it gets WeaponIndex from that picked up weapon , and adds it to this script.But it won’t work i don’t know why.

  1. It won’t detect collision
  2. How to add weapon number from weapon that i picked up to my pick up script.

Script is :
PickUP

var ShowGUI : boolean = false;
var PickUpE : Texture2D;
var script :  WeaponIndex;
var Index : int = 0;
var curWeapon : int = 0;

//******1)*******
//It won't detect collision between Character and weapon
 
function OnCollisionEnter (collide : Collider) {
	if(collide.gameObject.tag == "Weapons")
	{    
                //*****2)******
                //How to add WpIndex number to Index number that i have in this script

		script.GetComponent("WeaponIndex").WpIndex = Index;
		ShowGUI = true;

	}
}

function OnCollisionExit(isExitCollide : Collision)
{
	ShowGUI = false;
}

function OnGUI()
{
	if(ShowGUI)
	{
		GUI.DrawTexture(Rect(85,30,100,20), PickUpE);
	}
}

I used simple for Weapon Index.

WeaponIndex

//Weapon Number
var WpIndex : int = 0;

Anybody knows how to solve this.
Thanx for your time and help.

Hey! Code doesn’t make much sense to me.
1.What object is it attached to?
2.Why don’t you make any reference to the actual WeaponIndex?

when you say

var script :  WeaponIndex;

and then

script.GetComponent("WeaponIndex").WpIndex = Index;

aren’t you getting the same component you’re refering to?

If I were you, I’d reference the var script to the weaponindex script of the player, and then change it’s value. Bear in mind it’s a reference value, so it’s not copied but pointed to when you do this:
[CODE
script = GetComponent(“WeaponIndex”);
script.WpIndex = Index;
[/CODE]

This would be using your actual code. I think there are less convoluted ways of doing this :).

Happy coding!

from the help page for OnCollisionEnter

You don’t mention either the weapon or the char having a rigidbody…

Hi, thanks for reply.
I attached(WeaponPickUp Script) to my Player (Capsule) which has Character Controller . And the weapon that i want to collide with has rigidbody (Use Gravity checked , Is Kinematic unchecked).
I’m sorry if i didn’t make it more clearly
You see i wanted when my character hits Gun(That has Rigidbody) it gets that weapons index number.So i can use that number to activate(disabled) weapon. Something like :

if(curWeapon == 1)
{
MainWep = WpIndex;
}
if (WpIndex == 1 )
{
Weapon1 = True;
AllOtherWp = false;
}

Or if you know a better way to pick up weapons.
Something like that i don’t really know i just made it.
I hope it’s more understanding

Thanx for time
