Physics Pushable Bouncy Ball

Apply an impulse to an object to set it in motion. This happens in conjunction with an event. Requires click-listener and physics.

One physics feature is applying an impulse to an object to set it in motion. This happens in conjunction with an event. As an example, here we are setting object bounce_ball to respond to mousedown messages with an impulse with a certain force.

Additional Python properties are available in the PhysxForcePushable API Reference.

The following source code was mirrored from the arena-py physx_force_pushable.py example.

from arena import *

scene = Scene(host="arenaxr.org", scene="example")

@scene.run_once
def make_bounce_ball():
    # First, enable physics in the scene, and default scene bounding plane and cylinder.
    opt_obj = Object(
        object_id="scene-options",
        persist=True,
    )
    opt_obj.type = "scene-options"
    opt_obj.data["scene-options"] = {"physics": {"enabled": True, "useDefaultScene": True}}
    scene.add_object(opt_obj)

    # Next, create an object with physx-body to obey physics, and allow clicks to push it.
    bounce_ball = Sphere(
        persist=True,
        object_id="bounce_ball",
        radius=0.25,
        position=(0, 4, -1),
        material=Material(color="#ab1717"),
        click_listener=ClickListener(enabled=True, bubble=True),
