(Added first proposal) |
(Changed the wording about the "local" parameter. It should be possible to set the COG for child prims in a linked set as well as for root prims to simplify construction of machinery with moving parts.) |

Summary
Function: llSetCOG( vector cog, integer local );Overrides the automatic, volume based, computation of the prim's center of gravity. All rotations will instead be made around the given point. This includes llSetRot, llSetLocalRot, llTargetOmega as well as physics evaluation. In addition, the handles in edit mode will be positioned at the specified point.
| • vector | cog | – | position of the prim's center of gravity | |
| • integer | local | – | boolean, if TRUE cog is relative to the local coordinate system, if FALSE cog is relative to the parent coordinate system. If the prim is a single prim or the root prim in a linked set, that means the region coordinate system. |
Caveats
Expression error: Unexpected > operator.((TODO: Why is there an error here?))
Examples
Notes
A way to reset the COG back to the automatic computation might be useful as well.
