Hey,
I just thought I’d share this little tidbit. I don’t know whether you use an Object Orientated approach to your Corona Development, but if you do, neatly fitting display objects into any hierarchy you use can be a pain, particularly if you try to follow the model set out in Programming in Lua.
I figured I’d sit down and figure out an approach which would allow me to create a custom display group in much the same way I’d create any other object in Lua. A bit of headscratching later, and this is want I came up with
So here’s an example of how I’ve managed to create a custom display group:
CustomClass={}
function CustomClass:new()
o=display.newGroup()
local metatable=getmetatable(o)
local index=metatable.\_\_index
metatable.\_\_index= function (table,key)
if CustomClass[key] then
return CustomClass[key]
end
return index(table,key)
end
return o
end
function CustomClass:newFunction()
end
Usually a constructor function which creates a new group and defines new function on it would be a lot simpler to understand (and probably insulate you more from changes to the SDK), but this approach is a lot more consistent, and I think, will make inheritance cleaner to implement.
Let me know what you think! [import]uid: 11757 topic_id: 21470 reply_id: 321470[/import]
