Modding Discussion Need a bit of help with Lua

So I am trying to make an animation(frames) on the object play when you hit the craft or smelt button. One problem, I dont know how to program with lua(only a small basic idea) so I was hoping someone could help.


I took this from the beacon files
but it is simmilar to what I need

function onInteraction(args)
(NOTE: I don't want it on interaction(assuming that's when you hit e on the obj)
if not (no Idea what to put here) () then
object.setAnimationState("beaconState", "idle")
else
object.setAnimationState("beaconState", "active")
end
end


(no Idea what this stuff is)
function hasCapability(capability)
return false
end
