GUI.RepeatButtonUP

Unity Engine
1

This is insane @_@ I tried everything but i could not get what i want.

I wan to make a script that when i press my GUI.RepeatButton, it will send a command of true and when i release it will send a command of false.

how come there is no such thing as GUI.RepeatButtonDown, GUI.RepeatButton, and GUI.RepeatButtonUp just like the Input.mouseButton?

GUI commands have to go inside the OnGUI function/method. However, you shouldn’t put any actual scripts inside OnGUI, because it will be called multiple times a frame.

What would you could do is something like this (this is in C#):

public Texture2D buttonTexture;     // assign the texture in the Inspector panel
bool isPressed = false;

// Update is called once a frame (which can mean up to 60 times a second, depending on frame-rate)
void Update()
{
    if (isPressed == true)
   {
       // add your extra code here
   }
}

void OnGUI()
{
   // this creates the RepeatButton in the centre of the screen. I think isPressed will remain true as long as it is pressed.
   if(GUI.RepeatButton(new Rect(Screen.width / 2 - 50, Screen.height/2 - 50, 100, 100), buttonTexture) )
      isPressed = true;
}

thanks Philip for your time :slight_smile: but after pressing the GUI.RepeatButton, your isPressed statement always runs true. how will you make this false after releasing your GUI.RepeatButton?

I thought it would become false when the button was released - something I should probably check later. A quick work-around is to add a line into the OnGUI loop to reset isPressed to false afterwards, as follows:

void OnGUI()
{
   if (GUI.RepeatButton(...) ) // leave the button details out for now
   {
        isPressed = true;
   }
   isPressed = false;
}

The problem is, that line will be called multiple times a second, so I’m hoping somebody comes along with something that’s more optimised.

I think this will always returns false since the last statement the OnGUI will read is the isPressed = false.

maybe this will do

void OnGUI()

{
isPressed = false;

if (GUI.RepeatButton(…) ) // leave the button details out for now

{

isPressed = true;

}

}

but the main problem is that the isPressed = false; is always read twice per frame, this will add another calculation in the game.
Why can’t they just not create a GUI.Button just like Input.GetMouseButtonUp?

Yeah, you need to have an “else” clause in the “if” statement.

Alternatively, you could just use “isPressed = GUI.RepeatButton(…);” and it’ll do the same.
