OnMouse menu

Question

I have an idea for a menu where when you click on a button a bunch of other buttons appears:

 private void OnMouseOver()
     {
         if (Input.GetMouseButtonDown(0) && !EventSystem.current.IsPointerOverGameObject())
         {
             //Do stuff
         } 
     }

But I want it so that if you click again outside of the buttons the menu closes. I've tried:

 private void OnMouseExit()
         {
             if (Input.GetMouseButtonDown(0))
             {
                 //Do stuff
             } 
         }

But this doesn't work as it only registers when the mouse leaves the object and nothing else.

I think you need to store a state somewhere. This can be done simply with a bool:

 bool isMouseOver = false;
 
 void OnMouseEnter()
 {
     isMouseOver = true;
 }
 void OnMouseExit()
 {
     isMouseOver = false;
 }
 void Update()
 {
     if(!isMouseOver)
     {
         //Mouse is ooff the object
     }
 }

Yes I tried this but there are two problems with this:

void Update() { if(Input.Get$$anonymous$$ouseButtonDown(0) && !is$$anonymous$$ouseOver) { Debug.Log("d"); } }

The first problem is that eventhough I click once the Log message shows up 2-3 times in the console. I don't know why this is. The second problem is that if I try to disable the buttons like this: void Update() { if(Input.Get$$anonymous$$ouseButtonDown(0) && !is$$anonymous$$ouseOver) { //Disable menu buttons } }

Then they never appear. I don't think there's any way to do this using On$$anonymous$$ouseExit at all.

The function Get$$anonymous$$ouseButtonDown() should return true during the first frame that the button is pressed. If you are getting multiple log messages, maybe you have more than one instance?? I would really have to see more of your logic to see what’s happening here. There will certainly be a reasonable explanation to why you aren’t getting the expected results

I'll post my logic below.

     private void On$$anonymous$$ouseExit()
         {
             is$$anonymous$$ouseOver = false;
         }
     
     private void On$$anonymous$$ouseOver()
         {
     if (Input.Get$$anonymous$$ouseButtonDown(0) && !EventSystem.current.IsPointerOverGameObject())
             {
                 is$$anonymous$$ouseOver = true;
                 //Enable buttons
             }
             else if (Input.Get$$anonymous$$ouseButtonDown(0) && !is$$anonymous$$ouseOver)
             {
                 //Disable buttons
             }
     }

I converted your answer to a comment because it’s clearly not an answer. This logic doesn’t seem to make much sense. I think this should be more or less what is needed.

 private void On$$anonymous$$ouseEnter()
 {
     is$$anonymous$$ouseOver = true;
 }
 private void On$$anonymous$$ouseExit()
 {
     is$$anonymous$$ouseOver = false;
 }
      
 private void Update()
 {
      if (Input.Get$$anonymous$$ouseButtonDown(0))
      {
          if(is$$anonymous$$ouseOver && !button.gameObject.activeInHierarchy)
          {
                 //Enable buttons
          }
          else if(!is$$anonymous$$ouseOver && button.gameObject.activeInHierarchy)
          {
                  //Disable buttons
          }
      }
 }

 else if (!is$$anonymous$$ouseOver && EventSystem.current.IsPointerOverGameObject())
             {
                 //Disable buttons
             }
 
 This is the part that doesn't activate.
