Dynamic Text with DirectLabel?

Scripting Issues
1

Hello everyone. Sorry in advance for the long post. I am fairly new to Panda, some friends and I have just started learning it. My goal right now is to try and figure out part of the GUI functions, and make a menu.

So far I have a multi-level menu structure, and haven’t run into any real issues. What I was wanting to know though is if it’s possible to have dynamic text as part of a DirectLabel. I already have this working with OnscreenText. However, I was hoping to get it working with DirectLabel because I prefer the visual options available through it, and also just want to know if it’s possible.

What I am trying to do is simply display the value of a slider next to it.

Here is a snippet from my menu with the working OnscreenText:

        self.psRedValue = OnscreenText(parent = self.psmRedSlider,
                                       font = self.menuFont,
                                       fg = (0, 0, 0, 1),
                                       bg = (1, 1, 0.4, 1),
                                       scale = 0.18,
                                       pos = (1.3, 0, 0),
                                       mayChange = True)
        
        taskMgr.add(self.PSSliderValueTask, 'PSSliderValueTask')

def PSSliderValueTask(self, task):
        self.psRedValue.setText(str(int(self.psmRedSlider['value'] * 100)))
        return task.cont

And here is the snippet of my attempt with DirectLabel (I also tried using text_mayChange = True):

        self.psRedValue = DirectLabel(parent = self.psmRedSlider,
                                      text_font = self.menuFont,
                                      text_fg = (0, 0, 0, 1),
                                      frameSize = (-0.7, 0.7, -0.5, 0.7),
                                      frameColor = (1, 1, 0.4, 1),
                                      scale = 0.18,
                                      pos = (self.psmRedSlider, 1.3, 0, 0),
                                      textMayChange = 1)
        
        taskMgr.add(self.PSSliderValueTask, 'PSSliderValueTask')

def PSSliderValueTask(self, task):
        self.psRedValue(text = (str(int(self.psmRedSlider['value'] * 100))))
        return task.cont

The error I am getting is:

I also tried using DirectLabel with the setText command and recieved this error instead.

I tried searcing on the forums but couldn’t find anything related to this. So I’m not sure if I’m stuck using OnscreenText or if someone can point out a way to get this working with DirectLabel.

I only have some basic scripting experience from making some very simple game mods, so any help would be appreciated.

self.psRedValue["text"] = "your text here"

From the manual:

panda3d.org/manual/index.php/DirectGUI – scroll down beneath the keywords table.

It’s probably a little unintuitive to use dictionary notation for such stuff, but you’ll get used to it quickly, it doesn’t make that much of a difference most of the time.

Man, can’t believe I missed that, I read it only a few days ago. Thank you very much, it is working perfectly now.

Well I somehow doubt this will be the last simple question I end up asking on here. I’ll definitely try double checking every related part of the manual beforehand next time though.

Thank you again.
