Check if Mouse is on the buttons
Hello there! I'm making main menu when the mouse is on the buttons over screen a image will apears over right. I making the menu code only for gain experinece. I knew how to check if mouse is over a object using OnMouseOver, but how I can check if it's over/not over from start_button, creditos_button and quit_button function?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MainMenu : MonoBehaviour
{
public Texture title;
public Texture background_texture;
public Texture Start_texture;
public Texture Credits_texture;
public Texture Quit_texture;
void OnGUI()
{
background_box();
start_button();
credits_button();
quit_button();
}
void start_button()
{
GUI.Button(new Rect(Screen.height / 2 - 10, Screen.width / 2 - 30, 85, 25), "Start Game");
}
void credits_button()
{
GUI.Button(new Rect(Screen.height / 2 - 10, Screen.width / 2 + 5, 85, 25), "Credits");
}
void quit_button()
{
GUI.Button(new Rect(Screen.height / 2 - 10, Screen.width / 2 + 40, 85, 25), "Quit Game");
}
void background_box()
{
GUI.Box(new Rect(Screen.height / 2 - 40, Screen.width / 2 - 38, 150, 115), "");
}
void OnMouseOver()
{
}
}
-Store the rectangles you used to create those buttons.
-Then, in Update or OnGUI (not OnMouseOver), you can use https://docs.unity3d.com/ScriptReference/Input-mousePosition.html to get the position of the mouse.
-Compare the mouse position with each of those button Rects, to see if it contains the mouse position. (https://docs.unity3d.com/ScriptReference/Rect.Contains.html)
(the reason you don't use OnMouseOver, is because you want to detect a mouseover of those buttons, NOT a mouseover the monobehavior object itself.)
So I store this way, and I need to do next is just using mouseposition?
void start_button()
{
Rect start = new Rect(Screen.height / 2 - 10, Screen.width / 2 - 30, 85, 25), "Start Game");
GUI.Button(start);
}
Something like this I'd think... (untested)
if(start.Contains(Input.mousePosition) )
{
Debug.Log("mouse is over start button");
}
I'm receiving error CS0103: The name `iniciar' does not exist in the current context I'm try to call the function, but the ".Contains" cannot acess it.
void start_button()
{
Rect iniciar = new Rect(Screen.height / 2 - 10, Screen.width / 2 - 30, 85, 25);
GUI.Button(iniciar, "");
}
void Update ()
{
start_button();
if (iniciar.Contains(Input.mousePosition))
{
Debug.Log("mouse is over start button");
}
}
you can create a gameObject how follows the mouse position and create triggers for the button and OnTriggerEnter the mouse is over the buttons simple and briant
