Scripting Issues
1

I made this script. When I click down it goes to the next word.(makes it black) The problem is it only lets me go down one word before it stops working. I guess I don’t understand tasks a lot. :cry:

		wp.setTitle('Talking Guy')

		base.win.requestProperties(wp)
		
		self.image = OnscreenImage(image = 'title.png', pos = (0, 0, 0), scale = (1.5, 1, 1))
		self.image.setTransparency(TransparencyAttrib.MAlpha)
		
		FSM.FSM.__init__(self,'avatarFSM')

Thanks for taking the time to read this and Im pretty sure the error is pretty easy.

your code doesnt really make sense. you have a task (a task is called every frame) which changes the selection according to the last key you pressed, however you do not handle every possible case that can occur.

this is more like you want it to work, however it’s not handling the up-keys. also you could just change the color of the onscreentext’s, not destroying/creating them on every keypress:

run()

also you are inheriting from finite state machine, but you are not using it.
