I have a script called PlayerCharacter to control a player on a Unity 2D platform. It is perfect, it works as usual.
using UnityEngine; using System.Collections; using System.Collections.Generic; [RequireComponent(typeof (Rigidbody2D))] [RequireComponent(typeof(BoxCollider2D))] public class PlayerCharacter : MonoBehaviour { public float speed = 1.0f; public string axisName = "Horizontal"; private Animator anim; public string jumpButton = "Fire1"; public float jumpPower = 10.0f; public float minJumpDelay = 0.5f; public Transform[] groundChecks; private float jumpTime = 0.0f; private Transform currentPlatform = null; private Vector3 lastPlatformPosition = Vector3.zero; private Vector3 currentPlatformDelta = Vector3.zero; // Use this for initialization void Start () { anim = gameObject.GetComponent<Animator>(); } // Update is called once per frame void Update () { //Left and right movement anim.SetFloat("Speed", Mathf.Abs(Input.GetAxis(axisName))); if(Input.GetAxis(axisName) < 0) { Vector3 newScale = transform.localScale; newScale.x = -1.0f; transform.localScale = newScale; Debug.Log("Move to left"); } else if(Input.GetAxis(axisName) > 0) { Vector3 newScale = transform.localScale; newScale.x = 1.0f; transform.localScale = newScale; Debug.Log ("Move to Right"); } transform.position += transform.right*Input.GetAxis(axisName)*speed*Time.deltaTime; //Jump logic bool grounded = false; foreach(Transform groundCheck in groundChecks) { grounded |= Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground")); } anim.SetBool("Grounded", grounded); if(jumpTime > 0) { jumpTime -= Time.deltaTime; } if(Input.GetButton("jumpButton") && anim.GetBool("Grounded") ) { anim.SetBool("Jump",true); rigidbody2D.AddForce(transform.up*jumpPower); jumpTime = minJumpDelay; } if(anim.GetBool("Grounded") && jumpTime <= 0) { anim.SetBool("Jump",false); } //Moving platform logic //Check what platform we are on List<Transform> platforms = new List<Transform>(); bool onSamePlatform = false; foreach(Transform groundCheck in groundChecks) { RaycastHit2D hit = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground")); if(hit.transform != null) { platforms.Add(hit.transform); if(currentPlatform == hit.transform) { onSamePlatform = true; } } } if(!onSamePlatform) { foreach(Transform platform in platforms) { currentPlatform = platform; lastPlatformPosition = currentPlatform.position; } } } void LateUpdate() { if(currentPlatform != null) { //Determine how far platform has moved currentPlatformDelta = currentPlatform.position - lastPlatformPosition; lastPlatformPosition = currentPlatform.position; } if(currentPlatform != null) { //Move with the platform transform.position += currentPlatformDelta; } } }
The problem occurs when I try to change the script with a touch controller. I searched Google many times and modified the script as I could, and yet it does not give me any result (by the way, I'm new to Unity). Then I found a tutorial from the site about creating a touch controller with GUI graphics ( TouchControls ). I think the study guide is easy to learn. Here is the script
using UnityEngine; using System.Collections; [RequireComponent(typeof (Rigidbody2D))] [RequireComponent(typeof(BoxCollider2D))] public class TouchControls : MonoBehaviour { // GUI textures public GUITexture guiLeft; public GUITexture guiRight; public GUITexture guiJump; private Animator anim; // Movement variables public float moveSpeed = 5f; public float jumpForce = 50f; public float maxJumpVelocity = 2f; // Movement flags private bool moveLeft, moveRight, doJump = false; void Start () { anim = gameObject.GetComponent<Animator>(); } // Update is called once per frame void Update () { // Check to see if the screen is being touched if (Input.touchCount > 0) { // Get the touch info Touch t = Input.GetTouch(0); // Did the touch action just begin? if (t.phase == TouchPhase.Began) { // Are we touching the left arrow? if (guiLeft.HitTest(t.position, Camera.main)) { Debug.Log("Touching Left Control"); moveLeft = true; } // Are we touching the right arrow? if (guiRight.HitTest(t.position, Camera.main)) { Debug.Log("Touching Right Control"); moveRight = true; } // Are we touching the jump button? if (guiJump.HitTest(t.position, Camera.main)) { Debug.Log("Touching Jump Control"); doJump = true; } } // Did the touch end? if (t.phase == TouchPhase.Ended) { // Stop all movement doJump = moveLeft = moveRight = false; } } // Is the left mouse button down? if (Input.GetMouseButtonDown(0)) { // Are we clicking the left arrow? if (guiLeft.HitTest(Input.mousePosition, Camera.main)) { Debug.Log("Touching Left Control"); moveLeft = true; } // Are we clicking the right arrow? if (guiRight.HitTest(Input.mousePosition, Camera.main)) { Debug.Log("Touching Right Control"); moveRight = true; } // Are we clicking the jump button? if (guiJump.HitTest(Input.mousePosition, Camera.main)) { Debug.Log("Touching Jump Control"); doJump = true; } } if (Input.GetMouseButtonUp(0)) { // Stop all movement on left mouse button up doJump = moveLeft = moveRight = false; } } void FixedUpdate() { //anim.SetFloat("Speed", Mathf.Abs); // Set velocity based on our movement flags. if (moveLeft) { rigidbody2D.velocity = -Vector2.right * moveSpeed; } if (moveRight) { rigidbody2D.velocity = Vector2.right * moveSpeed; } if (doJump) { // If we have not reached the maximum jump velocity, keep applying force. if (rigidbody2D.velocity.y < maxJumpVelocity) { rigidbody2D.AddForce(Vector2.up * jumpForce); } else { // Otherwise stop jumping doJump = false; } } } }
But I don’t know how to implement the script from the tutorial ( TouchControls ) and assign it to the player control of the script ( PlayerCharacter ). How can I combine both scenarios so that the player can control it using the touch control?
