Can be used several times while a playback is in curse. - **Parameters:** - `time_factor` (_float_) – A value of 1.0 means normal time factor. A value < 1.0 means slow motion (for example 0.5 is half speed) A value > 1.0 means fast motion (for example 2.0 is double speed). - **apply_batch**(**self**, **commands**) This function executes the whole list of commands on a single simulation step. For example, to set autopilot on some actors, we could use: [sample_code](10c5f6a482/PythonAPI/examples/spawn_npc.py (L126)) We don't have control about the response of each command. If we need that, we can use apply_batch_sync(). - **Parameters:** - `commands` (_list_) – A list of commands to execute in batch. Each command has a different number of parameters. Currently, we can use these [commands](#command.ApplyAngularVelocity): SpawnActor DestroyActor ApplyVehicleControl ApplyWalkerControl ApplyTransform ApplyVelocity AplyAngularVelocity ApplyImpulse SetSimulatePhysics SetAutopilot. - **apply_batch_sync**(**self**, **commands**) This function executes the whole list of commands on a single simulation step, blocks until the commands are executed, and returns a list of [`command.Response`](#command.Response) that can be used to determine whether a single command succeeded or not.
