can you group functions? so that they remain in a scene

hi all,

is there a way to group together functions into a group (ie different levels have different functions that shouldnt trigger outside their respective levels( so that they dont run into the next level)

Not sure what you mean, but the easiest way is to put them into a table - OO-style:

[lua]game = {
level_1 = {},
level_2 = {},
level_3 = {}
}

function game.level_1:myFunction_1()
– CODE
end

function game.level_1:myFunction_2()
– CODE
end

function game.level_2:myFunction_1()
– CODE
end[/lua]

Also, you could also use more “logical” ways to write this:

[lua]game = {
functions = {},
curlevel = 1
}

function game.functions[1]:myFunction_1()
– CODE
end

function game.functions[1]:myFunction_2()
– CODE
end

function game.functions[2]:myFunction_1()
– CODE
end

– at some point, when you need them:

local funcs = game.functions[game.curlevel] – selects the current functions set

funcs:myFunction_1() – uses function 1[/lua]

This latter example also allows you to use same function names across different “levels”… if structure is similar, you can copy/paste most of the code from the first level! :slight_smile: [import]uid: 5750 topic_id: 3812 reply_id: 11582[/import]
