a2dTopLeft, a2dTopRight, a2dBottomLeft, a2dBottomRight equivalent for base.pixel2d?

Correct me if I misunderstood, but I guess your answer is to keep repositioning the pixel2d child node to the position of a2dTopLeft, etc every frame in a Task?

Yes, you are 99% right, but you have written more text on the forum than the code required for this task.

from direct.showbase.ShowBase import ShowBase
from panda3d.core import NodePath

class MyApp(ShowBase):

    def __init__(self):
        ShowBase.__init__(self)

        self.old_size = (0, 0)

        self.center = NodePath("center")
        self.center.reparent_to(pixel2d)

        self.p2dTopRight = NodePath("p2dTopRight")
        self.p2dTopRight.reparent_to(pixel2d)
        
        self.p2dTopLeft = NodePath("p2dTopLeft")
        self.p2dTopLeft.reparent_to(pixel2d)


        smiley = loader.load_model("smiley.egg")
        smiley.set_scale(20)
        smiley.reparent_to(self.p2dTopLeft)

        smiley = loader.load_model("smiley.egg")
        smiley.set_scale(20)
        smiley.reparent_to(self.p2dTopRight)

        smiley = loader.load_model("smiley.egg")
        smiley.set_scale(20)
        smiley.reparent_to(self.center)

        taskMgr.add(self.update, 'update')

    def update(self, task):
        size = (base.win.get_x_size(), base.win.get_y_size())
        if size != self.old_size:
            self.center.set_pos(int(base.win.get_x_size()/2), 0, -int(base.win.get_y_size()/2))
            self.p2dTopRight.set_pos(base.win.get_x_size(), 0, 0)
        self.old_size = size
        return task.cont

app = MyApp()
app.run()

But do not forget the panda is used on mini computers. And too much ShowBase functionality is unnecessary there. For example, I now use this method of creating an application.

Using Panda3D without "direct"

This is a minimal sample program showing how to open a window and render a model without using ShowBase, or indeed, any part of the direct module. This may be useful for certain low-level usage of Panda where ShowBase would just get in the way, or just for better understanding Panda under the hood. from panda3d.core import * engine = GraphicsEngine.get_global_ptr() pipe = GraphicsPipeSelection.get_global_ptr().make_default_pipe() # Open a window with requested properties fb_prop = FrameBuffe…

I got a bonus that the window opens instantly, no need to wait until the ShowBase window is initialized. In some cases, the user was able to increase the rendering speed to the buffer by simply abandoning ShowBase. Although before that he tried to enable multithreaded rendering, but stumbled over bugs. So the question is moot, adding a bunch of functionality and tasks to the already large ShowBase.
