Hi there I have this code in java:

@script RequireComponent( CharacterController )

if (useJoypad)
{
var joypos : Vector3 = Vector3(0,0, 0 );
Instantiate(JoystickPrefab, joypos, Quaternion.identity);
}

}

private var targetPosition:Vector3;

function Update () {

var movement = thisTransform.TransformDirection( Vector3( moveJoystick.position.x, moveJoystick.position.y, 0 ) );

// We only want horizontal movement

movement.Normalize();

// Horizontal
if (transform.position.x <= -6.5f)
transform.position = new Vector3(-6.5f, transform.position.y, transform.position.z);

}

// clamp acceleration vector to unit sphere
if (dir.sqrMagnitude > 1)
dir.Normalize();

// Make it move 10 meters per second instead of 10 meters per frame…
dir *= Time.deltaTime;

// Move object
transform.Translate (dir * speed);
}//iphone accelerometer END

//iphone touch/mouse START
if (useTouch)
{

for (var touch : iPhoneTouch in iPhoneInput.touches)

}

}//iphone touch/mouse END

//iphone joypad START

var characterVelocity = character.velocity;

var absJoyPos = Vector2( Mathf.Abs( moveJoystick.position.x ),Mathf.Abs( moveJoystick.position.y ) );

character.Move( movement );
}//iphone accelerometer END

if ((iPhoneInput.orientation == iPhoneOrientation.LandscapeLeft) (iPhoneSettings.screenOrientation != iPhoneScreenOrientation.LandscapeLeft))

And I translated the code in C sharp like this with no errors:

but I am getting a freeze screen when I start the app on my iphone. I think my code is badly ported to C sharp in this declaration part :

/JAVA - >/ var moveJoystick : Joypad;
/C sharp - >/ public Joystick moveJoystick; // it doesn’t let me put my joystick prefab on the editor like I do in java
// But in the java code I have no Transform or GameObject in this part, so what to do?

and in here I made this quick fix that I looked at google and didn’t find anything in start function:

cam = gameObject.FindWithTag(“MainCamera”).GetComponent(“Camera”); // JAVA
Camera cam = (Camera)gameObject.GetComponent(“Camera”); //C sharp quick fix???

So I let the code here and if you guys find it worth for an iphone Game controller please give me a hand on the C sharp that I need to take variables from another cs file , because i am pretty sure that it’s almost virtually impossible to take variables from C to java to use them globally…er ia mean publicly!

Any hints here? :expressionless:

FIXED I forgot to put my Joystick.cs and change my joypad.js on my joystickprefab and drag it and drop it on the editor!!

4

The code was fixed but my penelope joystick is not working anymore?
Why…on the unity + iOS pro it was working? And I haven’t touched anymore the code until I’bought the iOS basic. Is something wrong with my code?

Fixed the code and discovered that if you put create a GameObject variable and a script variable and in the editor if you drag and drop the same gameobject(the joystick) to both, the penelope joystick will stop working.The point is I was trying to instantiate the joystick and also use the script with the same gameobject and you can´t do this, so I fixed it creating another gameobject to spawn the joystick ( and other control types ) and with the first gameobject I used only the script variable + drag and drop with the editor( the joystick gameobject with the penelope script modified ). FIXED!!

I’m glad that’s over.

In the future, you can use tags to make your pasted code legible, and ideally only paste the parts that are giving you errors. In this case, the two lines you quoted at the very end of your second post were enough to see major errors.
