 The method will create, return and spawn an actor into the world. The actor will need an available blueprint to be created and a transform (location and rotation). It can also be attached to a parent with a certain attachment type.  
     - **Parameters:**
         - `blueprint` (_[carla.ActorBlueprint](#carla.ActorBlueprint)_) - The reference from which the actor will be created.  
         - `transform` (_[carla.Transform](#carla.Transform)_) - Contains the location and orientation the actor will be spawned with.  
         - `attach_to` (_[carla.Actor](#carla.Actor)_) - The parent object that the spawned actor will follow around.  
-        - `attachment` (_[carla.AttachmentType](#carla.AttachmentType)_) - Determines how fixed and rigorous should be the changes in position according to its parent object.  
+        - `attachment_type` (_[carla.AttachmentType](#carla.AttachmentType)_) - Determines how fixed and rigorous should be the changes in position according to its parent object.  
     - **Return:** _[carla.Actor](#carla.Actor)_

 This method is used in [__synchronous__ mode](https://[carla.readthedocs.io](#carla.readthedocs.io)/en/latest/adv_synchrony_timestep/), when the server waits for a client tick before computing the next frame. This method will send the tick, and give way to the server. It returns the ID of the new frame computed by the server.
