if you want to keep your current way of handling the walking mechanic, you need to add a few things.
- you also need to accept the arrow_up-repeat event to catch the respective event multiple times if the button is held down.
- you need to check if the walk animation is playing inside the Move function and only start it if it’s not.
- instead of play you need to use the loop function
- as it’s now looping indefinitely, you need to accept the arrow_up-up event to catch the event when the player releases the up arrow again
- add another function for the event caught in 4. in which you simply call self.pandaActor.stop() to stop the animations currently playing on it.
here’s how it would look like in the end:
from direct.showbase.ShowBase import ShowBase
from direct.actor.Actor import Actor
from direct.showbase import DirectObject
from direct.task import Task
class MyApp(ShowBase):
def __init__(self):
ShowBase.__init__(self)
# Load the environment model.
self.environ = self.loader.loadModel("environment")
self.environ.reparentTo(self.render)
# We do not have a skybox, so we will just use a sky blue background color
self.setBackgroundColor(0.53, 0.80, 0.92, 1)
self.pandaActor = Actor("models/panda-model",
{"walk": "models/panda-walk4"})
self.pandaActor.setScale(0.005, 0.005, 0.005)
self.pandaActor.reparentTo(self.render)
self.accept("arrow_up", self.Move)
self.accept("arrow_up-repeat", self.Move)
self.accept("arrow_up-up", self.stopMove)
self.accept("arrow_right", self.Move2)
self.taskMgr.add(self.camera_task, "camera")
def Move(self):
self.pandaActor.setY(self.pandaActor, -200)
self.pandaActor.setPlayRate(2, "walk")
walk = self.pandaActor.getAnimControl("walk")
if not walk.isPlaying():
self.pandaActor.loop("walk")
def stopMove(self):
self.pandaActor.stop("walk")
def Move2(self):
self.pandaActor.setH(self.pandaActor, -90)
def camera_task(self, task):
self.camera.setPos(self.pandaActor.getX(), self.pandaActor.getY() + 15, 3)
self.camera.lookAt(self.pandaActor)
return Task.cont
app = MyApp()
app.run()
Though, note, that this will result in a little pause between the initial down press of the button and the repeat event.
Also, note, that this is not really the typical way of handling this kind of things. Usually you’d use tasks, like you already did for your camera task, in which you check whether keys are pressed down and handle them in your code accordingly. I’ll show you how your code could be changed to use tasks as a more elegant alternative for the forward movement. I’ve left the rotation in the old way as in this case it would be the simpler way if you want a full 90° rotation each key press and not a partial rotation as long as the key is held down.
