GUI display weapon name you are looking at
Hello. I don't always ask questions on Unity Answers, but when I do, I need help REAL bad.
I have a First Person Shooter game made with FPS Kit 2 from [ArmedUnity.][1] When the player looks at a gun (using the Raycast Physics function) I want the GUI on the main camera to show the weapon name along with the price (I have not started that yet). Here is what I have so far:
// WeaponIndex.JS //
public var weaponPrice : int;
public var setWeapon : int; // Weapon Index
public var weaponName : String;
function Update () {
weaponName = gameObject.name;
}
This script (WeaponIndex.JS) is attached to every pickup weapon, and each weapon has a certain index (setWeapon). Then I have a weapon manager script attached to the main camera with the GUI stuff. Here is the onGUI function:
/**

var weaponsInUse : GameObject[]; // used weapons, among which you can switch.
var weaponsInGame : GameObject[]; // all weapons, which could be used in game
var worldModels : Rigidbody[]; // just a prefab which could be instantiated when you drop weapon
var hit : RaycastHit;
var distance : float = 2.0;
var layerMaskWeapon : LayerMask;
var layerMaskAmmo : LayerMask;
var dropPosition : Transform;
var weapIndex : WeaponIndex;
var switchWeaponTime : float = 0.5;

So as you (should) see, not all of the script is on there. What I would like is for the script to recognize what weapon the Raycast is looking at and display the weapon's name and price. The problem is, right now the GUI only displays the Weapon with the first Weapon Index number (which is the Sniper, 1). Sorry if this is too long and belongs in the forums, but this is urgent!

All I see here is a line that would display "notes" and "textFromPickupScript" neither of which are shown in this code. How are they set, or is that your question?
@getyour411 +getyour411 I put in the entire script. please help!
I could give you the unityproject so you can review everything. I am just completely stuck.
Does this bit of code
if (Physics.Raycast (position, direction, hit, distance, layer$$anonymous$$askWeapon.value)){
//Debug.Log(hit.collider.gameObject.weapIndex.weaponPrice);
weaponName = hit.collider.gameObject.name;
work - were you able to get the Raycast to send the weapon name to debug.log? If not, do you have your guns on the layer selected with layer$$anonymous$$askWeapon layer
For first question - No it doesn't. I have a feeling the problem has to do with the Raycast hit getting the GameObject's script. But I think youre onto something on the second question. I guess you suppose I am not on the layer$$anonymous$$askWeapon layer when I look at it?
