Problem trying ShadowDemo.py

[system]

Hello,

perhaps someone can help me out.
I put the ShadowDemo.py code into my file for a scene to test Shadows.
All I do then is creating an instance of the Shadowcaster-class:
Shadow = ShadowCaster(myLight,myFloor)

When I run the scene, i get the error message:
ParasiteBuffer instance has no attribute getChannel

I have no idea what went wrong, since the buffer is created in the ShadowCaster-class:
self.buffer = base.win.makeTextureBuffer(‘shadowBuffer’, self.texXSize, self.texYSize)

Btw Panda is configured to OpenGL

the Code of ShadowCaster

class ShadowCaster:
texXSize = 256
texYSize = 256

def __init__(self, lightPath, objectPath):
    self.lightPath = lightPath
    self.objectPath = objectPath
    self.groundPath = None

    # Create an offscreen buffer to render the view of the avatar
    # into a texture.
    self.buffer = base.win.makeTextureBuffer(
        'shadowBuffer', self.texXSize, self.texYSize)

    # The background of this buffer--and the border of the
    # texture--is pure white.
    clearColor = VBase4(1, 1, 1, 1)
    self.buffer.setClearColor(clearColor)
    self.tex = self.buffer.getTexture()
    self.tex.setBorderColor(clearColor)
    self.tex.setWrapu(Texture.WMBorderColor)
    self.tex.setWrapv(Texture.WMBorderColor)

    # Set up a display region on this buffer, and create a camera.
    layer = self.buffer.getChannel(0).makeLayer()

The version of ShadowDemo.py you are looking at has unfortunately suffered from bit rot–it’s using an old Panda3D interface that has since been changed. Sorry about that!

Please make the following modification. Change lines 42 and 43 of ShadowDemo.py from the following two lines:

        layer = self.buffer.getChannel(0).makeLayer()
        dr = layer.makeDisplayRegion()

To this single line:

        dr = self.buffer.makeDisplayRegion()

How do you use this?
