Este código faz mover o texto ao pressionar certas teclas do mouse ou teclado:

from direct.gui.OnscreenText import OnscreenText
from direct.showbase.DirectObject import DirectObject

texto = OnscreenText("arrow_left - esquerda\narrow_right - direita\nmouse1 - cima\nmouse2 - baixo\na (pressionar) - direita e cima\na (soltar) - centralizar")

	global x
	global y
	x -= 0.01
	texto.setPos(x, y)

	global x
	global y
	x += 0.01
	texto.setPos(x, y)

	global x
	global y
	y += 0.01
	texto.setPos(x, y)

	global x

	global y
