Title: Help with tween and touch
Post by: Dreeka on June 18, 2012, 11:14:34 AM

Hey,

I am experimenting with NGUI, and I have two issues.

First, I am trying to create a virtual button. If the button is held down, the player should move forward, and if the button is released, the player should stop.

I have tried it in the following way:

1.     function OnPress ()
2.     {
3.         pController.goUp = true;
4.     }
5.      
6.     function OnRelease()
7.     {
8.         pController.goUp = false;
9.     }

Secondly, I want my buttons to work in the following way:
When I click on the button, the tween effects should play from start to finish. But instead, if I release th button, the tween effects stops as well. To counter this, I have created a custom script:

1.     function OnClick()
2.     {
3.         tweenColor.enabled = true;
4.         tweenScale.enabled = true;
5.        
6.         yield WaitForSeconds(0.4);
7.        
8.         tweenColor.enabled = false;
9.         tweenScale.enabled = false;
10.        
11.         label.color = Color.white;
12.         this.transform.localScale   = Vector3(1, 1, 1);
13.     }

But with this script, the tweens start to "break" after a few clicks.

Is there any solutions for my problems?

Thanks!

There is no "OnRelease". OnPress() function has a boolean flag indicating whether the button was pressed or released, like so:

C# version:

1. void OnPress (bool isPressed)

Thanks!

I was able to get it working in the following way:

1. var pController : PlayerController;
2. var isPressedG : boolean = false;
3.  
4. function OnPress (isPressed : boolean)
5. {
6.         isPressedG = isPressed;
7.         //print (isPressedG);
8. }
9.  
10. function Update ()
11. {
12.      pController.goUp = isPressedG;
13. }

Any thought on the other issue?

UITweener (base class for all tweens) has a method to play them:

1. UITweener.Play(bool forward);

I don't suggest enabling/disabling components yourself.
