Script Problem

Unity Engine
1

I’m trying to do a tic tac toe game.In the code i put three variables

var x:GameObject;
var ball:GameObject;
var choice:GameObject;

When it will instantiate,it instantiate choice var:

var part=Instantiate(choice,transform.position,transform.rotation);

I create a OnGui function with two buttons to tweak between x or ball:

function OnGUI()
{
if (GUI.Button (Rect (10,75,50,50), "X")) {
		choise=x;
	}
	if (GUI.Button (Rect (10,10,50,50), "Ball")) {
		choise=ball;
	}
}

But this code doesn’t works:( Where is the problem?
Full Code

var x:GameObject;
var ball:GameObject;
var choice:GameObject;
var inserted=false;
function OnMouseDown()
{
put();
}
function put()
{
if(inserted==false)
{
var part=Instantiate(choice,transform.position,transform.rotation);
inserted=true;
}
}

function OnGUI()
{
if (GUI.Button (Rect (10,75,50,50), "X")) {
		choise=x;
	}
	if (GUI.Button (Rect (10,10,50,50), "Ball")) {
		choise=ball;
	}
}

Sorry for my bad English:(

what error are you getting ?

try this one :

var x:GameObject;
var ball:GameObject;
var choice:GameObject;
var inserted=false;
//function OnMouseDown()
//{
//put();
//}
function put()
{
if(inserted==false)
{
var part=Instantiate(choice,transform.position,transform.rotation);
inserted=true;
}
}

function OnGUI()
{
if (GUI.Button (Rect (10,75,50,50), "X")) {
		choise=x;
                put();
	}
	if (GUI.Button (Rect (10,10,50,50), "Ball")) {
		choise=ball;
                put();
	}
}

Oh no this boolean is here because x or ball can be only inserted one time in each part

i’m not sure what you mean but you can also do this :

var x:GameObject;
var ball:GameObject;
var choice:GameObject;
var inserted=false;

function put(obj:GameObject)
{
	if(inserted==false)
	{
		var part=Instantiate(obj,transform.position,transform.rotation);
		inserted=true;
	}
}

function OnGUI()
{
	if (GUI.Button (Rect (10,75,50,50), "X")) {
                put(x);
	}
	if (GUI.Button (Rect (10,10,50,50), "Ball")) {
                put(ball);
	}
}

But if I want to make the instatiate by mouse?I try this but doesn’t work:

var x:GameObject;
var ball:GameObject;
var choice:GameObject;
var inserted=false;

function OnMouseDown(obj:GameObject)
{
if(inserted==false)
	{
		var part=Instantiate(obj,transform.position,transform.rotation);
		inserted=true;
	}
};

function OnGUI()
{
	if (GUI.Button (Rect (10,75,50,50), "X")) {
                OnMouseDown(x);
	}
	if (GUI.Button (Rect (10,10,50,50), "Ball")) {
                OnMouseDown(ball);
	}
}

your combining onMouseDown with Ongui, somehow i think that would give issues. i don’t know which one would get executed first. But again, what error are you getting ?
Also this last script you posted will never work. The onMouseDown is expecting a gameobject input.

This error appear:

Failed to call function OnMouseDown of class Game
Calling function OnMouseDown with no parameters but the function requires 1.
UnityEngine.SendMouseEvents:smile:oSendMouseEvents()

You can’t declare OnMouseDown with a parameter. The error arises because Unity internally tries to call it without any parameters but your version of the function expects a GameObject to be passed.
