How Do You Select A Game Object By Using the Left Mouse Button?
Hey everyone I am trying to make a game but one of the main parts to it is selecting game objects with the left mouse button. I was wondering if anyone knew the java script to allow you to click on a game object and the game object change color or something as a result. Also just to mention I have very little experience with this and have done little to no coding/scripting or whatever it is called. I have checked google and the results I have found have been of little help due to my inexperience. Also does anyone know how to make this work for prefab or instantiated objects too? Any help is appreciated.
I dont use javascript. But a good tip is to try raycasting. You could easily get the gameobject by doing so. :)

Does anybody read the docs? http://docs.unity3d.com/Documentation/ScriptReference/RaycastHit-collider.html
Im certain it is but im new to this and have practically no idea what most of it means, but thank you for the help none the less.
A common method is to use Raycast in a camera script, and change the hit object properties - like this:
var hitTransform: Transform; // transform of currently selected object
function Update(){
if (Input.GetMouseButtonDown(0)){ // if left mouse pressed...
// create ray passing through the mouse pointer:
var ray = camera.ScreenPointToRay(Input.mousePosition);
var hit: RaycastHit;
if (Physics.Raycast(ray, hit)){ // if something was hit...
hitTransform = hit.transform; // get a reference to its transform
//
// and do whatever you want with this object here
//
}
}
}
The variable hitTransform holds the transform of the last object clicked.
Okay thank you so much this is exactly what I needed.
I have an issue though because the object I want to select is going to be a prefab and this works fine for selecting a game objects but how can I select prefabs individually in this method?
Well, prefab selection is editor script stuff: you must save your script in Assets/Editor and use the Editor classes - there's a Selection class that lists all selected objects. I played too little with Editor scripts, but suppose that you don't have to worry about the selection code - just inspect the Selection class to know which objects are selected.
