# This tutorial is intended as a initial panda scripting lesson going over
|
|
# display initialization, loading models, placing objects, and the scene graph.
|
|
#
|
|
# Step 2: After initializing panda, we define a class called World. We put
|
|
# all of our code in a class to provide a convenient way to keep track of
|
|
# all of the variables our project will use, and in later tutorials to handle
|
|
# keyboard input.
|
|
# The code contained in the __init__ method is executed when we instantiate
|
|
# the class (at the end of this file). Inside __init__ we will first change
|
|
# the background color of the window. We then disable the mouse-based camera
|
|
# control and set the camera position.
|
|
|
|
# Initialize Panda and create a window

|
|
# instead of the default grey

|
# By default, the mouse controls the camera. Often, we disable that so that
|
|
# the camera can be placed manually (if we don't do this, our placement
|
|
# commands will be overridden by the mouse control)

# Now that our class is defined, we create an instance of it.
