Yeah, I played around with it and came up with something. It's odd, but now it works how I need it to. I want my Adventure engine to have as good of a drag and drop object/actor library as it can get.

Really looking forward to it.

How's come I can do this:
Code: Select all
enemySet.goomba = {}

function enemySet.goomba:setup(v)
  ...
end
But I can't do this:
Code: Select all
enemySet["goomba"] = {}

function enemySet["goomba"]:setup(v)
  ...
end

Yeah, I've come across that many times; Lua syntax doesn't allow it for some reason.

Lua is about speed. I think the parser could be changed to support this type of grammar, but it wouldn't bring any benefit (you could use alternative ways), and it would slow down the parsing phase.

You could try this:

Code: Select all

enemySet["goomba"] = {}

enemySet["goomba"].setup=function(self, v)
  ...
end

I think it is because the function blah () ... end form uses an identifier rather than an expression. a.b and a:b are simply special cases. Like miko said, that way it is probably faster.

Yeah I'd say that's it.
