# PRIM_SCRIPTED_SIT_ONLY

*LSL constant*

```lsl
integer PRIM_SCRIPTED_SIT_ONLY = 40;
```

Constant groups: [PrimParam](/constants/groups/PrimParam/), [PrimParamGet](/constants/groups/PrimParamGet/)

Agents may only be seated on this prim using [llSitOnLink](/functions/llSitOnLink/). Attempts to do a manual sit will fail. This flag applies even outside of an experience enabled region.

If any prim in a linkset has `PRIM_SCRIPTED_SIT_ONLY` set and no other prim in the linkset has a sit target then an avatar cannot manually sit on the object.

If some other prim in the linkset does have a sit target (that is not filled or marked `PRIM_SCRIPTED_SIT_ONLY`), the agent can sit on that prim.
