[JS]Utiliser Joystick

[Waerin]

Bonjour, pour mon script de véhicule, j'utilisais accéléromètre ( on pivote le téléphone pour bouger et ça avance tout seul) mais je ne trouve pas cela pratique, je préfère le traditionnel joystick qui est biebn plus pratique. Mais je n'arrive pas à modifier le script afin d'utiliser des josticks merci d'avance .

Mon code de véhicule à partir d'un tuto pour pc que j'ai modifié pour le mobile

Code : Tout sélectionner

var FrontLeftWheel : WheelCollider;
var FrontRightWheel : WheelCollider;


var GearRatio : float[];
var CurrentGear : int = 0;


var EngineTorque : float = 600.0;
var MaxEngineRPM : float = 3000.0;
var MinEngineRPM : float = 1000.0;
private var EngineRPM : float = 0.0;



function Start () {
	
	rigidbody.centerOfMass.y = -1.5;
}

function Update () {
	
	
	rigidbody.drag = rigidbody.velocity.magnitude / 250;
	
	
	EngineRPM = (FrontLeftWheel.rpm + FrontRightWheel.rpm)/2 * GearRatio[CurrentGear];
	ShiftGears();

	
	audio.pitch = Mathf.Abs(EngineRPM / MaxEngineRPM) + 1.0 ;
	.
	if ( audio.pitch > 2.0 ) {
		audio.pitch = 2.0;
	}

	
	FrontLeftWheel.motorTorque = EngineTorque / GearRatio[CurrentGear] *  Input.acceleration.x;
	FrontRightWheel.motorTorque = EngineTorque / GearRatio[CurrentGear] *  Input.acceleration.y;
		
	// les accéléromètres .
	FrontLeftWheel.steerAngle = 10 *  Input.acceleration.x;
	FrontRightWheel.steerAngle = 10 *  Input.acceleration.y;
}

function ShiftGears() {
	
	if ( EngineRPM >= MaxEngineRPM ) {
		var AppropriateGear : int = CurrentGear;
		
		for ( var i = 0; i < GearRatio.length; i ++ ) {
			if ( FrontLeftWheel.rpm * GearRatio[i] < MaxEngineRPM ) {
				AppropriateGear = i;
				break;
			}
		}
		
		CurrentGear = AppropriateGear;
	}
	
	if ( EngineRPM <= MinEngineRPM ) {
		AppropriateGear = CurrentGear;
		
		for ( var j = GearRatio.length-1; j >= 0; j -- ) {
			if ( FrontLeftWheel.rpm * GearRatio[j] > MinEngineRPM ) {
				AppropriateGear = j;
				break;
			}
		}
		
		CurrentGear = AppropriateGear;
	}
}

Merci d'avance

Il faut remplacer Input.acceleration par les valeurs retournés par ton joystick.

Je ne comprends pas comment faire , pourrais vous me donner un exemple ?

Tu peux trouver des codes pour joystick sur google, dans les tutos de Unity, sur unify, ...

Je compte utiliser celui fourni avec Unity
