Android Touch Game Menu

Hey
I've made a 2d game but it starts directly when I open it on android
I want it to show a menu screen that shows
Play and Exit Buttons with the logo over them
I've searched alot but I found scripts that only works on PC and never worked on android touch screens


Help pleaase

 

Use Input.GetTouch. That'll tell you where on the screen the user has touched. If that is inside a GUITexture then the button has been pressed.

 

how to use touch here ?

if(GUI.Button(Rect(55, 100, 180, 40), "Start game")) {
var script = GetComponent("MainMenuScript");
script.enabled = false;

}

 

I'm not an Android expert, but your code "just works" on an iOS device. What happens/doesn't happen on your Android?

 

Tiny slice of how I do it:

Code (CSharp):

1. if (MOBILE == false) { hit = Physics2D.Raycast (Camera.main.ScreenToWorldPoint (Input.mousePosition), Vector2.zero); }
2.         else                { hit = Physics2D.Raycast (Camera.main.ScreenToWorldPoint (Input.GetTouch(0).position), Vector2.zero);}
3.  
4.         if (hit.collider) { // THIS is how you null-check a raycast's collider!
5.  
6. //Do stuff.
7.  
8. }

How it works: I heard OnGUI calls are horrible for a mobile game's performance. The info may be inaccurate or outdated, but just in case, I made my buttons sprites with colliders instead.

Raycasting to a worldpoint like that will check anything on the camera that gets clicked or touched, provided it has a collider on it. (If you're going mobile only, GetTouch(0)'s what you're gonna want.) I don't have an iOS device to test this on, but it works like a charm on Android.

 

Well I'm pretty sure Input.GetMouseButtonDown(0) which checks for left mouse click, works with mobile as well, as the first touch.

I don't recommend using it if you're going to use multitouch later on, because it does some weird things (it uses the average position between all touches I think). But for single touch it works well.

But regarding Input.GetTouch functionality... you should also need to know about Input.touchCount, which checks the amount of touches currently pressed on the screen... it's zero when you're not touching the screen, and it's 1 or more, depending how many fingers you're pressing on the screen.

So what you do is make a for loop to retrieve all touches.

for (var i = 0; i < Input.touchCount; ++i) {
var thisTouch : Touch = Input.GetTouch(i);
}

So in that for loop you can access what's going on with the screen touches, by retrieving the info within the Touch variable.
If you want to know, for example, the position of the touch, you access it within the Touch variables.

for (var i = 0; i < Input.touchCount; ++i) {
var thisTouch : Touch = Input.GetTouch(i);
var touchPosition : Vector2 = thisTouch.position;
}

The touch position was stored in the variable touchPosition, and you can use it to do a Camera.mainScreenToWorldPoint, as Kawaburd said.

 

Thanks All for Help

Am not actually that experienced person in those things so can someone give me a clear tutorial please??
And the last Gui button I used worked with pc mouse but didn't even show on Android like it starts the game directly

 

Those examples are as simple as they nearly can be. I suggest you start by visiting the top bar Learn section and continue with scripting tutorials. When you master them you can adapt the code in your own needs.
