Actuator

Connect world and body, then set force/torque at full command. command is a synchronized scalar from -1 to1; input, AI or other Zero components can write it. For a vehicle, one actuator can apply forward thrust and another yaw torque. Choose body space to follow the chassis orientation, or world space for fixed directions. Set command0 to release or active=false to disable. Multiple actuators sum in deterministic entity-id order without overwriting Body.force/torque.

Commands are sampled at each World request boundary (up to four fixed steps). They feed the existing Skate solver and do not move transforms directly or add a rider. Input-device bindings stay in normal Zero input components; this asset does not assume keyboard keys, a game genre or a multiplayer transport.
