示例1: ParentSafetyAdjust

// modify targpos directly to aim short of dangerous bodies

frame = frame->GetParent()->GetNonRotFrame(); // check next frame down
}
if (!body) return false;
// aim for zero velocity at surface of that body
// still along path to target

}示例2: l_space_spawn_ship_near
/*
* Function: SpawnShipNear
*
* Create a ship and place it in space near the given <Body>.
*
* > ship = Space.SpawnShip(type, body, min, max, hyperspace)
*
* Parameters:
*
* type - the name of the ship
*
* body - the <Body> near which the ship should be spawned
*
* min - minimum distance from the body to place the ship, in Km
*
* max - maximum distance to place the ship
*
* hyperspace - optional table containing hyperspace entry information. If
* this is provided the ship will not spawn directly. Instead,
* a hyperspace cloud will be created that the ship will exit
* from. The table contains two elements, a <SystemPath> for
* the system the ship is travelling from, and the due
* date/time that the ship should emerge from the cloud.
*
* Return:
*
* ship - a <Ship> object for the new ship
*
* Example:
*
* > -- spawn a ship 10km from the player
* > local ship = Ship.SpawnNear("viper_police_craft", Game.player, 10, 10)
*
* Availability:
*
* alpha 10
*
* Status:
*
* experimental
