Joystick para Android/IOS en C# Unity3D
Buenas, hoy os comparto un script para hacer un Joystick en C#. Es un port de un script que ya viene en Unity3D y que podéis encontrar en Standard Asset Mobile, este Script estaba en javascript y bueno, lo pasé a C#. Espero que a alguien le sea útil.
using UnityEngine;

// PORT DE Joystick.js A Joystick.cs
//Nicolás Sánchez Baile
// Joystick creates a movable joystick (via GUITexture) that
// handles touch input, taps, and phases. Dead zones can control
// where the joystick input gets picked up and can be normalized.
//
// Optionally, you can enable the touchPad property from the editor
// to treat this Joystick as a TouchPad. A TouchPad allows the finger
// to touch down at any point and it tracks the movement relatively
// without moving the graphic

Saludos ;)
Me funcionó a la perfección gracias.
ResponderEliminarGracias, me funciona muy bien. Mi problema ahora es que mi nave se sale de la pantalla tanto en el eje x como vertical y estoy tratando de limitar la pantalla para impedir que la nave la sobrepase. En un foro me han comentado que esto lo puedo hacer con mathf clamp, y he visto ejemplos de su implementación pero ninguno para joystick y lo intento pero algo debo estar mal :( Sabes como puedo solucionarlo?
ResponderEliminarGracias de antemano.
Ya he podido lograrlo ,llevo dos días con esto xD Voy a dejar el código que he utilizado por si a alguien le puede venir bien, si no te importa.
ResponderEliminarUn saludo.

}
private void Clamp()

if (clampWidth)

_newPosition.x = Mathf.Clamp (_newPosition.x,_lowerLeftCorner.x,_upperRightCorner.x);
}
if (clampHeight)

}
if (clampWidth ||clampHeight)

}
Me parece una gran idea porque seguro que más gente se ha encontrado con este problema. Un saludo!
