Simple script addition. I just noticed today that when using llSetPrimitiveParams() that the only rotation option is PRIM_ROTATION, however this behaves identically to llGetRot() which means that local rotations won't work in it. The suggestion therefore is to simply add a PRIM_LOCALROT (or similarly named) parameter in so that we can do batch updates using local rotations. For example, on a child prim the following code: llSetPrimitiveParams([PRIM_POSITION, localPos, PRIM_LOCALROT, localRot]); Would be the equivalent of: llSetPos(localPos); llSetLocalRot(localRot); However it can be done in a single step this way. This would of course need to work with related primitive parameter functions.
