Show Canvas when button is clicked, Unity 5.2.3

[Francesco_Mesiano]

Hi guys, I wanted to ask you a question about how I can activate and deactivate a canvas component using a button. I have this code:

public GameObject[] optionPanels; 

	public void openPanel(GameObject selectPanel)
	{
		foreach(GameObject opPanel in optionPanels)
		{
			opPanel.SetActive(false);
		}
		
		selectPanel.SetActive(true);
	}

But I do not know how to turn it off when I click on the button again, help!

public GameObject optionPanels;
private bool panelsState ;
private bool panelOpen ;

// Specify this function in the `OnClick` callback of your button
public void TogglePanel(GameObject selectPanel)
{
	if( panelOpen )
		ClosePanel();
	else
		OpenPanel( selectPanel );
}

public void OpenPanel(GameObject selectPanel)
{
	if( panelsState == null )
		panelsState = new bool[optionsPanels.Length];
		
	for( int i = 0 ; i < optionsPanels.Length ; ++i )
	{
	    // Save the current state of the panels
		panelsState _= optionsPanels*.activeSelf;*_

_ optionsPanels*.SetActive(false);
}*_

* selectPanel.SetActive(true);*
* panelOpen = true ;*
}
public void ClosePanel()
{
if( panelsState != null )
{
* for( int i = 0 ; i < optionsPanels.Length ; ++i )*
* {*
optionsPanels_.SetActive(panelsState*);
}
}
panelOpen = false ;
}*_
