2D mobile: Need my character to rotate Z axis towards touch position
Hi, I'm new to Unity, programming and stuff. My math understanding is very basic.
I have created code ( some taken from tutorials, some made by me ) that creates a virtual joystick.
The virtual joystick works like this: It stores the initial touch location ( TouchPhase.Began ) and calculates the direction where the user is moving or has moved the finger ( TouchPhase.Moved, TouchPhase.Stationary ) relative to the initial touch location.
It then moves the GameObject accordingly.
Now, I need to rotate the GameObject so that it faces the direction of the touch relative to the initial touch location.
This is the code I have for the Joystick. It works nice, feel free to use it if you need it, but please help me figure out this rotation issue.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class InvisibleMovingJoystick : MonoBehaviour
{
public GameObject phage;
public float speed = 1.0f;
private bool touchStart = false;
Vector2 pointA;
Vector2 pointB;
// Update is called once per frame
void Update()
{
if(Input.touchCount == 1)
{
Touch touch = Input.GetTouch(0);
if (touch.phase == TouchPhase.Began)
{
//I'm taking the screen coordinates instead of the world coordinates of the touch
//So that even if the camera moves, which it does following the character
//The initial position will never change
pointA = touch.position;
}
if (touch.phase == TouchPhase.Moved || touch.phase == TouchPhase.Stationary)
{
pointB = touch.position;
touchStart = true;
}
else
{
touchStart = false;
}
}
}
private void FixedUpdate()
{
if(touchStart == true)
{
Vector2 offset = pointB - pointA;
Vector2 direction = Vector2.ClampMagnitude(offset, 1.0f);
moveCharacter(direction * 1);
//rotateCharacter();
}
}
void moveCharacter(Vector2 direction)
{
phage.transform.Translate(direction * speed * Time.deltaTime);
}
void rotateCharacter()
{
//pls help
}
}
