Give lua a simple means for NULL_KEY evaluating as false

planned

WolfGang Senizen

LSL

key sitter = llAvatarOnSitTarget( );
if(sitter) {
    // Do stuff
}

This is probably one of the most used "hack" / "hidden features" of lsl.

Would be amazing if lua could have it too

Lua

Maybe something like this

local sitter = ll.AvatarOnSitTarget()
if sitter.isValid() then
    -- Do stuff
end

Good point! We're adding a

uuid_val.istruthy

(all lowercase is convention in Lua builtins, apparently) to mimic what LSL would do in the if (uuid) {...} case. We're also going to start setting our UUID constants like

NULL_KEY

as actual

uuid

instances to make it less annoying to compare them.
