Secondlife functions like ll.GetObjectDetails , ll.SetLinkPrimitiveParams , ll.ParticleSystem that take lists as arguments require integer and booleans inside them to be converted to a userdata integer object. This is extremely cumbersome for basic use. An example ll.ParticleSystem({ integer(0), integer(bit32.bor(0x100,0x400,0x008)), integer(9), integer(0x01), integer(17), 1.0, integer(1), vector(0.8,0.0,0.0) }) It would be great if luau could be setup to allow for the use of normal number types and booleans. Like this ll.ParticleSystem({ 0, bit32.bor(0x100,0x400,0x008), 9, 0x01, 17, 1.0, 1, vector(0.8,0.0,0.0) }) Correctly "cast" constants would improve this somewhat, but still leaves allot to be desired. For now I have made myself a function to "auto cast" these for me, but that is sub optimal at best... function table2FuncList(tab) for k,v in pairs(tab) do if type(v) == "number" and math.round(v) == v then tab[k] = integer(v) elseif type(v) == "boolean" then tab[k] = integer(v and 1 or 0) end end return tab end
