# VEHICLE_FLAG_HOVER_TERRAIN_ONLY

*LSL constant*

```lsl
integer VEHICLE_FLAG_HOVER_TERRAIN_ONLY = 0x8;
```

Constant groups: [VehicleFlag](/constants/groups/VehicleFlag/)

Makes the vehicle float over land.

If you wanted to make a boat you should set the [VEHICLE_FLAG_HOVER_WATER_ONLY](/constants/VEHICLE_FLAG_HOVER_WATER_ONLY/) flag, or if you wanted to drive a hover tank under water you would use the [VEHICLE_FLAG_HOVER_TERRAIN_ONLY](/constants/VEHICLE_FLAG_HOVER_TERRAIN_ONLY/) flag instead. Finally, if you wanted to make a submarine or a balloon you would use the [VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT](/constants/VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT/).

The vehicle flags are independent of each other and that setting two contradictory flags will have undefined behavior. The flags are set using the script call [llSetVehicleFlags](/functions/llSetVehicleFlags/).

### Constants

|

| Flags |  | Description |
| --- | --- | --- |
| [VEHICLE_FLAG_NO_DEFLECTION_UP](/constants/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](https://en.wikipedia.org/wiki/Bumper_car), from climbing their linear deflection into the sky. |
| [VEHICLE_FLAG_LIMIT_ROLL_ONLY](/constants/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](/constants/VEHICLE_FLAG_HOVER_WATER_ONLY/) | 0x004 | Ignore terrain height when hovering. |
| [VEHICLE_FLAG_HOVER_TERRAIN_ONLY](/constants/VEHICLE_FLAG_HOVER_TERRAIN_ONLY/) | 0x008 | Ignore water height when hovering. |
| [VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT](/constants/VEHICLE_FLAG_HOVER_GLOBAL_HEIGHT/) | 0x010 | Hover at global height instead of height above ground or water. |
| [VEHICLE_FLAG_HOVER_UP_ONLY](/constants/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](/constants/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](/constants/VEHICLE_BANKING_TIMESCALE/). This is to help prevent ground vehicles from steering when they are in mid jump. |
| [VEHICLE_FLAG_MOUSELOOK_STEER](/constants/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](/constants/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](/constants/VEHICLE_FLAG_CAMERA_DECOUPLED/) | 0x200 | Makes [mouselook](https://wiki.secondlife.com/wiki/mouselook) [camera](/categories/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](/constants/VEHICLE_FLAG_BLOCK_INTERFERENCE/) | 0x400 | Prevents attachments worn by the vehicle's passengers from pushing the vehicle via [llPushObject](/functions/llPushObject/) and similar functions. |
