Category:LSL Integer/bit mask

bit_mask is a subtype of bit_field

↳ bit_field is a subtype of integer.

The functions and constants in this category all take or return a bit_mask parameter. Events in this category expose a bit_mask parameter.

The big difference between a bit_mask and a bit_field is that a bit_mask is usually the bits you want to manipulate in the bit_field.

Values

bit_mask values are often made up of one or more of the following special values:

Flags		Description
VEHICLE_FLAG_NO_DEFLECTION_UP	0x001	This flag prevents linear deflection parallel to world z-axis. This is useful for preventing ground vehicles with large linear deflection, like  bumper cars, from climbing their linear deflection into the sky.
VEHICLE_FLAG_LIMIT_ROLL_ONLY	0x002	For vehicles with vertical attractor that want to be able to climb/dive, for instance, airplanes that want to use the banking feature.
VEHICLE_FLAG_HOVER_WATER_ONLY	0x004	Ignore terrain height when hovering.
VEHICLE_FLAG_HOVER_TERRAIN_ONLY	0x008	Ignore water height when hovering.
VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT	0x010	Hover at global height instead of height above ground or water.
VEHICLE_FLAG_HOVER_UP_ONLY	0x020	Hover doesn't push down. Use this flag for hovering vehicles that should be able to jump above their hover height.
VEHICLE_FLAG_LIMIT_MOTOR_UP	0x040	Prevents ground vehicles from motoring into the sky. This flag has a subtle effect when used with conjunction with banking: the strength of the banking will decay when the vehicle no longer experiences collisions. The decay timescale is the same as VEHICLE_BANKING_TIMESCALE. This is to help prevent ground vehicles from steering when they are in mid jump.
VEHICLE_FLAG_MOUSELOOK_STEER	0x080	Steer the vehicle using the mouse. Use this flag to make the angular motor try to make the vehicle turn such that its local x-axis points in the same direction as the client-side camera.
VEHICLE_FLAG_MOUSELOOK_BANK	0x100	Same as above, but relies on banking. It remaps left-right motions of the client camera (also known as "yaw") to rotations about the vehicle's local x-axis.
VEHICLE_FLAG_CAMERA_DECOUPLED	0x200	Makes mouselook camera rotate independently of the vehicle. By default the client mouselook camera will rotate about with the vehicle, however when this flag is set the camera direction is independent of the vehicle's rotation.
VEHICLE_FLAG_BLOCK_INTERFERENCE	0x400	Prevents attachments worn by the vehicle's passengers from pushing the vehicle via llPushObject and similar functions.
