How to move 2D Gameobjects using GUITextures?

Questions & Answers

Hi guys,

I’m trying to implement simple buttons to move my 2D character around the screen, and make him able to use any of the available functions in my PlayerControl script. I have my keyboard controls all set and done, but I don’t know how to implement some touch features. I have some GUITexture GameObjects set up, however, I don’t know how to hook up the code so that the touch buttons may communicate with my PlayerControl script.

How may I achieve this?

This is what my PlayerControl script looks like:

using UnityEngine;
using System.Collections;

public class PlayerControl : MonoBehaviour
{
		public float moveSpeed = 4f;
		public float jumpSpeed = 200f;
		public bool grounded, interact = false;
		public Transform lineStart, lineEnd, groundedEnd, destination;
		float jumpTime, jumpDelay = .5f;
		bool jumped;
		Animator anim;
		RaycastHit2D interaction;

		void Start ()
		{
				anim = GetComponent<Animator> ();
		}

		// Update is called once per frame
		void Update ()
		{
				Movement ();
				Raycasting ();
		}

		// Movement script
		void Movement ()
		{

				anim.SetFloat ("speed", Mathf.Abs (Input.GetAxis ("Horizontal")));
				anim.SetFloat ("falling", Mathf.Abs (rigidbody2D.velocity.y));

				//move right
				if (Input.GetAxisRaw ("Horizontal") > 0) {
						transform.Translate (Vector2.right * moveSpeed * Time.deltaTime);
						transform.eulerAngles = new Vector2 (0, 0); //rotate character
				}

				//move left
				if (Input.GetAxisRaw ("Horizontal") < 0) {
						transform.Translate (Vector2.right * moveSpeed * Time.deltaTime);
						transform.eulerAngles = new Vector2 (0, 180); //rotate character
				}
				
				//jump if grounded
				if (Input.GetKeyDown (KeyCode.Space) && grounded == true) {
						rigidbody2D.AddForce (Vector2.up * jumpSpeed);
						jumpTime = jumpDelay;
						anim.SetTrigger ("jump");
						jumped = true;
				}

				jumpTime -= Time.deltaTime;
				if (jumpTime <= 0 && grounded && jumped) {
						anim.SetTrigger ("landing");
						jumped = false;
						anim.SetTrigger ("ground");
				}

				if (Input.GetKeyDown (KeyCode.E) && interact == true) {
						transform.position = destination.position;
				}
		}

		//raycasting for interacts and jumping
		void Raycasting ()
		{
				Debug.DrawLine (lineStart.position, lineEnd.position, Color.green);
				Debug.DrawLine (this.transform.position, groundedEnd.position, Color.green);

				grounded = Physics2D.Linecast (this.transform.position, groundedEnd.position, 1 << LayerMask.NameToLayer ("Ground"));

				if (Physics2D.Linecast (lineStart.position, lineEnd.position, 1 << LayerMask.NameToLayer ("Princess"))) {
						interaction = Physics2D.Linecast (lineStart.position, lineEnd.position, 1 << LayerMask.NameToLayer ("Princess"));
						interact = true;
				} else {
						interact = false; 
				}
		}
}

At first glance your script is fine. Don’t use GUITexture for things that move tho. They’re made for static things like… GUIs. I don’t think their position changes anything.

Use planes, and put your textures on those instead.

Sorry guys, I figured it out.

I can show the fixes I did to make it work if anyone wants.
