Deep Notes

This function is roughly equivalent to the following: <lsl> float maxAbs(vector a){ return llListStatistics(LIST_STAT_MAX, [llFabs(a.x), llFabs(a.y), llFabs(a.z)]); }

integer ScaleByFactor(float scale) { if(scale == 0) return ERR_MALFORMED_PARAMS;

integer prims = llGetNumberOfPrims(); vector root = llGetScale() * scale; if(maxAbs(root) > 64) return ERR_MALFORMED_PARAMS; list set = [PRIM_LINK_TARGET, prims > 1, PRIM_SIZE, root];

if(prims > 1) { list get = []; int count = prims; do { get += [PRIM_LINK_TARGET, count, PRIM_POS_LOCAL, PRIM_SIZE]; } while(--count); get = llGetPrimitiveParams(get); count = 0; do { vector size = llList2Vector(get, ++count) * scale; vector pos = llList2Vector(get, ++count) * scale; if(maxAbs(size) > 64
