Hello,
 
I have been working on a 2D Platformer and I am at the point where I want to add mobile controls for the phone. I am new to unity so I need some help.
 
Here is what I have:
  •      The basic gameplay is waves of aliens come from above and you have to shoot them. The aming is right now controlled by the mouse. The gun follows the mouse
  •      basic movement is controlled with the arrow keys and space bar
  •      I also have the Unity standard assets in my project as well
Here is what I want:
  •      I want to have 2 joysticks one that controls the movement of the player and one that controls the aming and shooting
  •      For shooting I want to be already shooting when you place your finger on the joystick
 
If someone could please help me with it. Tell me what to add and stuff like that would be really appreciated!!
 
Here are some of my scripts:
 
PlayerController:
          
using System;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;
 
namespace UnityStandardAssets._2D
{
    [RequireComponent(typeof (PlatformerCharacter2D))]
    public class Platformer2DUserControl : MonoBehaviour
    {
        private PlatformerCharacter2D m_Character;
        private bool m_Jump;
 
 
        private void Awake()
        {
            m_Character = GetComponent<PlatformerCharacter2D>();
        }
 
 
        private void Update()
        {
            if (!m_Jump)
            {
                // Read the jump input in Update so button presses aren't missed.
                m_Jump = CrossPlatformInputManager.GetButtonDown("Jump");
            }
        }
 
 
        private void FixedUpdate()
        {
            // Read the inputs.
            bool crouch = Input.GetKey(KeyCode.LeftControl);
            float h = CrossPlatformInputManager.GetAxis("Horizontal");
            // Pass all parameters to the character control script.
            m_Character.Move(h, crouch, m_Jump);
            m_Jump = false;
        }
    }
}
