Hello,

I don´t understand why these erros are comming up. Is the last code line.

–>(39,49): error CS0119: Expression denotes a type', where a variable’, value' or method group’ was expected

–>(39,31): error CS1502: The best overloaded method match for `UnityEngine.GUI.HorizontalSlider(UnityEngine.Rect, float, float, float)’ has some invalid arguments

–>(39,31): error CS1503: Argument #1' cannot convert object’ expression to type `UnityEngine.Rect’

I am a newbie, so please answer with some explanation and code or I will not understand, thank you.

using UnityEngine;
using System.Collections;

public class BotonesMenu : MonoBehaviour {

	public float puntMax;
	float velChange;


	// Use this for initialization
	void Start () {
		puntMax = 2000.0f;
	}
	
	// Update is called once per frame
	void Update () {
		
	}
	
	void OnGUI () {
		// Make a background box
		GUI.Box(new Rect(Screen.width/2 - 150,10,300,300), "Menu");
		
		// Make the first button. If it is pressed, Application.Loadlevel (1) will be executed
		if(GUI.Button(new Rect(Screen.width/2 - 40,40,80,20), "1 jugador")) {
			Application.LoadLevel("PrimerEscenario-GuardadoManualmente");
		}
		
		// Make the second button.
		if(GUI.Button(new Rect(Screen.width/2 - 40,70,80,20), "2 jugadores")) {
			Application.LoadLevel(2);
		}

		GUI.Label (new Rect (Screen.width / 2 - 30, 120, 60, 20), "Opciones");

		GUI.Label (new Rect (Screen.width / 2 - 90, 150, 180, 30), "Puntuacion para ganar: "+puntMax);


		puntMax = GUI.HorizontalSlider (Rect(Screen.width / 2 - 100, 175, 200, 10), puntMax, 0, 50000);
	}
}

You should change :

puntMax = GUI.HorizontalSlider (Rect(Screen.width / 2 - 100, 175, 200, 10), puntMax, 0, 50000);

To this :

puntMax = GUI.HorizontalSlider (new Rect(Screen.width / 2 - 100, 175, 200, 10), puntMax, 0, 50000);

you should put “new” before Rect in c#
