... plus additional parameters

MoKaLux

I have a question please
I found how to use ... in a function, my question is can we pass additional params?
For example I have my base class:

LF_Dynamic_Character_Base = Core.class(Sprite) function LF_Dynamic_Character_Base:init( xworld, xspritesheet, xname, xcols, xrows, xscalex, xscaley, xanchorx, xanchory, xoffsetx, xoffsety, xdensity, xrestitution, xfriction, xBIT, xCOLBIT, xNAME)

Then I can do this:

LF_Dynamic_Player = Core.class(LF_Dynamic_Character_Base)   function LF_Dynamic_Player:init(...)

But this doesn't work with additional parameters:

LF_Dynamic_Bat = Core.class(LF_Dynamic_Character_Base)   function LF_Dynamic_Bat:init(..., xposx, xposy, xmove)

Thank you for your help.

Yloinks, that is a lot! When you have so many options it is generally better to pass them as a table..

local options = { xworld = myWorld, xspritesheet = someSpriteSheet, xname = 'abc', xcols = 0, xrows = 0, xscalex = 0, xscaley = 0, xanchorx = 0, xanchory = 0, xoffsetx = 0, xoffsety = 0, xdensity = 0, xrestitution = 0, xfriction = 0, xBIT = 0, xCOLBIT = 0, xNAM = 0, }   LF_Dynamic_Character_Base(options)

hello there antix

I do as you showed but not in this case.

I build my levels based on Tiled (as you told me before )

-- *************** -- PLAYER & OTHERS -- *************** if objectName == "player" then self.player = LF_Dynamic_Player.new( xworld, "gfx/player/caverman_97x71.png", "player", 6, 7, 1, 1, nil, nil, 0, -5, 1, nil, nil, G_BITPLAYER, playercollisions, G_PLAYER) self.player.body:setPosition(object.x, object.y) self.mg:addChild(self.player) elseif objectName:sub(1,3) == "bat" then local nme01 if objectName == "bat01" then nme01 = LF_Dynamic_Bat.new(xworld, "gfx/nmes/sprite-sheet-121x89.png", objectName, 5, 4, 1, 1, nil, nil, nil, nil, 1, nil, nil, G_BITENEMY, nmecollisions, G_ENEMY01, object.x, object.y, 1) -- *** EXTRA PARAMS TO BAT *** end nme01.body:setPosition(object.x, object.y) nme01:joint(object.x, object.y) self.mg:addChild(nme01) xworld.bats[nme01] = nme01.body

The bat enemy has some extra params which I'd like to incorporate using (..., extra1, extra2). Is this possible?

?

local Foo = Core.class(Sprite)   function Foo:init(a,b) self.a = a self.b = b end   local Bar = Core.class(Foo, function(c,d,...) return ... end) --< "..." must be at the end   function Bar:init(c,d) self.c = c self.d = d end   local foo = Foo.new(1,2) print(foo.a, foo.b) --< 1, 2 local bar = Bar.new(3,4, 1,2) --< 1, 2, 3, 4 print(bar.a, bar.b, bar.c, bar.d)
