Problem with keyboard/events

General Discussion
#1

Hello, I’m new to panda3d and I’m trying to move an object with the keyboard, I don’t see any problem with my code compared to the examples, but it just won’t work. I get the following error:

self.accept( 'arrow_left' , x_minus )
AttributeError: MyApp instance has no attribute 'accept'
:task(error): Exception occurred in PythonTask eventManager

here is my code:

def x_plus():
	cursor.setX(cursor.getX() + 0.1)
	
def x_minus():
	cursor.setX(cursor.getX() - 0.1)
	
def y_plus():
	cursor.setY(cursor.getY() + 0.1)

def y_minus():
	cursor.setY(cursor.getY() - 0.1)


class MyApp():
    def __init__(self):  
	
        # Load Models
        cursor = loader.loadModel("app/models/cursor")
        cursor.reparentTo(render)

        # Set Position, Scale and Orientation
        cursor.setScale(0.05)
        cursor.setPos(0,0,1.15)

        self.accept( 'arrow_left' , x_minus )
        self.accept( 'arrow_right' , x_plus )
        self.accept( 'arrow_up' , y_plus )
        self.accept( 'arrow_down' , y_minus )

Thanks in advance for your help!

You forgot to inherit from DirectObject.

from direct.showbase.DirectObject import DirectObject
(...)
class MyApp(DirectObject):
(...)
