Scripting Issues
1

So now i have an image, a wordwrapped text that loads 2 lines at a time on the image, after u press Enter, and unloads everything after the final line was displayed.
Its almost done, only one thing: how can i make the text appear slowly like here:
youtube.com/watch?v=FGsfYfySBUI
just an example.
I use this to display the text:
text.setText(var)

Create a task that adds one letter to the text every few milliseconds.

I thought of tasks…

        timestep = 0.1  # seconds
        taskMgr.doMethodLater(timestep, self.addLetters, "add letters")

            self.onscreendisplay.setText(self.temp)
