Selecting a game object through the screen

I want to to have a script where i want to make a target. I need to select it through the screen by clicking on the object through a script on my main person and not the other guy I have a collider on thing I'm trying to select.

 

You need to raycast to your target, the result of which will return your targets gameobject.

 

ok im trying this script but it is giving me errors and not even picking up unless my guy is facing him

if(Input.GetMouseButton(0)){
Vector3 fwd = transform.TransformDirection(Vector3.forward);
if (Physics.Raycast(Camera.current.transform.position, fwd, 100))
print("There is something in front of the object!");
Debug.DrawRay(Camera.current.transform.position, fwd, Color.white,0.01f);
}

 

just to let you know this camera doesn't really rotate like a fps but instead its a 3rd person camera

 

I use this to select objects:

Code (csharp):

1.  
2. Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
3. RaycastHit hit;
4. if (Physics.Raycast(ray, out hit, 1000))
5.        {
6.            GameController.selection = hit.transform.gameObject;
7.            print(GameController.selection);
8.            cam.target = hit.transform;
9.        }
10.  

Hope it helps.

 

where does the GameController come from?

 

Ignore camecontroller, that's particular to his project... your target is hit.transform.object, so use it however you like.

 

ok i tried doing what you've said but still nothing works for me. This has got to be one of the most confusing things I've done so far.

 

Hi Chippy,

Could you use the OnMouseDown function, something like this? First make a small script like this, call it something like "PickTarget" and attach it to the object you want to be the target (which has to have a collider, like a cube for example).

Code (csharp):

1. var targetPicked : String;
2.  
3. function OnMouseDown () {
4.     targetPicked = "target picked";
5. }

Then add something like this to your main person script:

Code (csharp):

1. private var makeTarget : GameObject;
2. private var foundTarget : String;
3.  
4. function Start () {
5.     makeTarget = GameObject.Find("target");
6. }
7.  
8. function Update () {
9.     foundTarget = makeTarget.GetComponent(PickTarget).targetPicked;
10.     Debug.Log (foundTarget);
11.    
12. }

This works by referencing the small script you added to the target object from within the Main Person script by first finding it,

Code (csharp):

1. makeTarget = GameObject.Find("target");
2. }

and then referencing the variable "targetPicked" you made in that little script.

Code (csharp):

1. foundTarget = makeTarget.GetComponent(PickTarget).targetPicked;
