Toggling Gui Visiblity

#1

//in default.binds.cs
function toggleFirstPerson(%val)
{
   if (%val)
   {
      $firstPerson = !$firstPerson;
   }
}

moveMap.bind(keyboard, tab, toggleFirstPerson);

This function is defined in your default.binds.cs script. I'm sure the $firstPerson variable is linked into the actual engine code, and it checks that value when its time to render a new frame.

Anyhow, I'd just stick a function right below the change in $firstPerson

I also highly suggest you dont set something to be "awake" or "asleep" manually like that, do something a little less obtrusive. Take a look at how the player list is turned on/off

function PlayerListGui::toggle(%this)
{
   if (%this.isAwake())
      Canvas.popDialog(%this);
   else
      Canvas.pushDialog(%this);
}

Hope this helps,
Jared

#2 Yes Jared... that is a great help!

Slowly but surely, this is starting to make sense. As you can probably tell from my coding "style" I am actually a C programmer who is "force feeding" myself C++! LOL

Thanks for your help.

#3 Okay, I am getting some pretty weird results. I have tried this several different ways, but the end result is this:

When I call Canvas.pushDialog(DashPanel); the image blows up to the size of the screen, and then won't return to normal when I call Canvas.popDialog(DashPanel)!

I don't get it?!

#4 If you are going to use Canvas.pushDialog(); and Canvas.popDialog(); make sure that the GUI element you are specifying is a clear full screen element, and the GUI object you want to show is placed where you want it to be.

Another method to do the above that would work would be to use the .add method.

function YourGUI::toggle(%this)
{
if (%this.isAwake())
Canvas.getContent.Add(%this);
else
Canvas.getContent.Remove(%this);
}

#5 AHA!

I looked through the Torque Scripting reference, but found no details on the Canvas.pop/push functions.

Now it makes sense! Can't wait to get home and 'fix' it! =D

Thanks Harold. You da' man!

#6 I guess the best explanation is that pushDialog pushes a new GUI "SCREEN" onto the Canvas stack, and popDialog pops the GUI "SCREEN" off of the stack.

You can then use canvas.getContent(); to check what specific "dialogs" are currently being displayed and based on that decide on an action to perform.


add and remove work a bit different.

Add will add a GUI "ELEMENT" to a SCREEN regardless of if it is on the canvas stack or not.

remove will remove a GUI "ELEMENT" from a screen regardless of if it is on the canvas stack or not.

#7 Yikes! I thought I had this figured out, but apprently I need someone to hold my hand and walk me through. I am just not getting it.

First of all, in playGui.cs I have defined the following function as Harold suggested:

function  DashPanel::dashToggle(%this)
{
   if (%this.isAwake())
      Canvas.getContent.Add(%this);
   else
      Canvas.getContent.Remove(%this);
}

Then in default.bind.cs, I modified toggleFirstPerson as follows:

function toggleFirstPerson(%val)
{
   if (%val)
   {
      $firstPerson = !$firstPerson;
   }
   
   DashPanel.dashToggle(); //this is the only change
}

Okay, to qualify this, I have tried a number of different approaches, but nothing seems to work.

I verified that the function was being called during the camera toggle... experimented with the pop and pushDialog some more... but that is less memory efficient than I like. ;)

I apologize if my questioning seems ignorant... it IS! ;)

If someone would be willing to walk me through this step by step I'd be forever greatful. I am having a h*ll of a time wrapping my head around this engine!

#8 canvas.getContent().add
canvas.getContent().remove

You need the () after getContent.

#9 ROFLMAO!!!!

I am SUCH an idiot! Thanks Harold... it works beautifully! I REALLY appreciate your help. =)

#10 Hi all,

I'm having some troubles (Torque newbie you see :) so was just testing out the toggle dialog on the Loadinggui one from the examples.

I've setup my key bind stuff in default.bind.cs
moveMap.bind( keyboard, 0, JamboToggleOptions );

And have the proc (also in default.bind.cs)
function JamboToggleOptions()
{
LoadingGui.toggle();
}


Also... in 'loadinggui.cs'

function LoadingGui::toggle(%this)
{
if (%this.isAwake())
{ Canvas.getContent().Add(%this);
}
else
{ Canvas.getContent().Remove(%this);
}
}


However Im getting the following error?
Set::remove Object "LoadingGui" does not exist in set

But if goto the console and type:
Canvas.getContent().Add(LoadingGui); works.

Very (very) stuck and any help would be most appreachiated.

Thanks in advance.
Jamie
