How to detect mouse click on GUITexture in unity

Question

I am trying to add controls through mouse in place of keyboard in the game. I added 4 movement keys and 1 fire button through the GUI texture in unity. In the game there is already a player controller which controls the player through keyboard strokes

I didnt get, how to make the player move if the direction button (GUITexture) is clicked

Button Script

using UnityEngine; using System.Collections;

public class RightButton : MonoBehaviour {

public Texture2D bgTexture;
public Texture2D airBarTexture;
public int iconWidth = 32;
public Vector2 airOffset = new Vector2(10, 10);


void start(){
    }

void OnGUI(){
    int percent = 100;

    DrawMeter (airOffset.x, airOffset.y, airBarTexture, bgTexture, percent);
}

void DrawMeter(float x, float y, Texture2D texture, Texture2D background, float percent){
    var bgW = background.width;
    var bgH = background.height;

    GUI.DrawTexture (new Rect (x, y, bgW, bgH), background);

    var nW = ((bgW - iconWidth) * percent) + iconWidth;

    GUI.BeginGroup (new Rect (x, y, nW, bgH));
    GUI.DrawTexture (new Rect (0, 0, bgW, bgH), texture);
    GUI.EndGroup ();


}

}

I am unable to add the GUI Button in place of GUI.DrawTexture, its giving invalid argument error and so i am unable to add how to check the button is clicked or not

Thanks

GUITexture is part of the legacy GUI system. An example of how to get this to work as a button is here.

using UnityEngine;
using System.Collections;

public class RightButton : MonoBehaviour {

    public Texture bgTexture;
    public Texture airBarTexture;
    public int iconWidth = 32;
    public Vector2 airOffset = new Vector2(10, 10);


    void start(){
    }

    void OnGUI(){
        int percent = 100;

        DrawMeter (airOffset.x, airOffset.y, airBarTexture, bgTexture, percent);
    }

    void DrawMeter(float x, float y, Texture texture, Texture background, float percent){
        var bgW = background.width;
        var bgH = background.height;

        if (GUI.Button (new Rect (x, y, bgW, bgH), background)){
            // Handle button click event here
        }

        var nW = ((bgW - iconWidth) * percent) + iconWidth;

        GUI.BeginGroup (new Rect (x, y, nW, bgH));
        GUI.DrawTexture (new Rect (0, 0, bgW, bgH), texture);
        GUI.EndGroup ();
    }
}
