Scenes in ARENA-py

Scenes give ARENA-py programs access to an ARENA scene. It provides an interface to add/update objects, run animations, and many more!

Scene Access

To get access to a scene in the ARENA, create a Scene object. Make sure you have proper permissions to access it!

scene = Scene(host="arenaxr.org", scene="example")
# scene = Arena(host="arenaxr.org", scene="example") works too

Arguments

host: Base ARENA URL.

realm: ARENA realm name.

scene: ARENA scene name.

namespace: ARENA namespace. Default value is ARENA username.

debug: If True, print authentication debug information and every published message. Ignore this parameter.

network_latency_interval: Interval (in ms) to run network graph latency update. Default value is 10000 (10 secs). Ignore this parameter.

Callbacks

See Scene Callbacks.

Access to Persisted Objects

To get access to Objects in the persist database, you can use get_persisted_obj.

@scene.run_once
def main():
    obj = scene.get_persisted_obj(object_id)
    print(obj) # obj should be an object in persist with persist=True

You can also just do:

@scene.run_once
def main():
    obj = scene.all_objects[object_id]
    print(obj) # obj should be an object in persist with persist=True
