Hello everyone, for the last one month nearly I am trying to make my project suitable for multitouch. So far it’s working only as a single touch and what I am looking for is when I am trying to go forward I also want to rotate the camera with another finger.
Also I am having a second issue with the current version, the code that I am using at the moment works fine in Unity application but when I try to build it as a project (lexe file) and try to run it. It’s not detecting any touches.
Does anyone have solutions for this ? Cheers
Here’s the code I am using at the moment ;
using UnityEngine;
using System.Collections;
public class Control : MonoBehaviour {
public bool kJoystikEnabled = true;
public float kJoystickSpeed = 0.5f;
public bool kInverse = false;
public float kMovementSpeed = 10;
//public GUITexture BtnArrow;
//GameObject av = GameObject.Find("3rd Person Controller/AV");

int leftFingerId = -1;
int rightFingerId = -1;
Vector2 leftFingerStartPoint;
Vector2 leftFingerCurrentPoint;

Vector2 rightFingerCurrentPoint;
Vector2 rightFingerLastPoint;
bool isRotating;
bool isMovingToTarget = false;
Vector3 targetPoint;
Rect joystickRect;
private GameObject av;
void MoveFromJoystick()
{
isMovingToTarget = false;
Vector2 offset = leftFingerCurrentPoint - leftFingerStartPoint;
if (offset.magnitude > 10)
offset = offset.normalized * 10;
characterController.SimpleMove(kJoystickSpeed * ownTransform.TransformDirection(new Vector3(offset.x, 0, offset.y)));
}
void MoveToTarget()
{
if(!av) {
Vector3 difference = targetPoint - ownTransform.position;
//av.SendMessage("Walk","");
characterController.SimpleMove(difference.normalized * kMovementSpeed);
//av.SendMessage("Stand","");
Vector3 horizontalDifference = new Vector3(difference.x, 0, difference.z);
if (horizontalDifference.magnitude < 0.1f)
isMovingToTarget = false;
}
}
void SetTarget(Vector2 screenPos)
{

{
targetPoint = hit.point;

}
}
