Inheritance from multiple classes

marcelojunior

Sorry for my english.

I need to extend from multiple classes.
I've created a classe named animate (animate = Core.class())
And i have to extend these in other classes like: mesh = Core.class(Mesh, animate).
This is to use the animate methods.

Thanks. (:

i will, for now, implementing all the methods in all classes

As far as I know, Gideros not support multiple inheritance.
Use aggregation instead of inheritance or try this http://www.lua.org/pil/16.3.html

Would it help you if animate class was already inheriting from Mesh?
as:

animate = Core.class(Mesh) mesh = Core.class(animate)

asakharov: I tried to use this example, but without success.

ar2rsawseen: up would work, but the classes that going to extend the animate are: sprite, mesh and bitmap, then it would not work.

Mash and Bitmaps - inherits from Sprite.
So, maybe you just want a Sprite interface to implement the animation?
If so, then you can write:

Animation = Core.class()   function Animation:init(spriteObject) self.Object = spriteObject ... end   funtion Animation:MakeWonderfulEffect() --operations with self.Object as a Sprite object ..... end   .......   local test1 = Mesh.new(...) local test2 = Bitmap.new(...) local test3 = Sprite.new(...) loca animation1 = Animation.new(test1) loca animation2 = Animation.new(test2) loca animation3 = Animation.new(test3)   animation1:MakeWonderfulEffect() animation2:MakeWonderfulEffect() animation3:MakeWonderfulEffect()

Yah, I really liked this example \o/

I abstracted some gideros classes/methods to make more easy to use.
Example:

mesh = Core.class(Mesh) -- some methods to abstract Mesh class   local background = mesh.new() background:addVertice(0, 0) -- addVertice() make the relation with the Mesh directly background:addVertice(0, 100) background:addVertice(100, 100) background:addVertice(0, 0)

With your example, i will implement the animation, transformation etc.. classes, for Bitmap, Sprite, Shape, Mesh, and methods like addVertice for example can be used in Shape or Mesh classes, its amazing \o/

thanks asakharov and ar2rsawseen for Help.
