[quote:3ko3zuxj]I read that C2 loads required images/objects only when the Layout is loaded.
I guess this means that C2 doesn't load every image in the whole project but, just images from current layout.
You can load images at runtime using load image from URL which might be a bit misleading when actually you can load images from your project files using "DesertGroundTile.png" for example but, it seems you cannot specify the path. If you are using NodeWebkit and want to load textures from files externally you can use "NodeWebkit.AppFolder&"Textures/Desert/GroundTile.png". And of course you can also load them from URL.
Just note that if you are using Sprite object you cannot create frames at runtime (at least not at the moment) but, something I've been using is to make tiny 2x2 frames where those images can be loaded. If you have predefined amount of different tile types you should't have to do this.
[quote:3ko3zuxj]Can I create a common Platform Sprite and have each Level images grouped under various Animations?
Will C2 still load all the level images into Memory even if I am not calling the animation?
Don't put all your tiles into animations they are all loaded no matter if you use the animation or not.
About the actual levels. If you want to keep everything inside the project one way to do this is if you have another project just for level building. Then you run the map layout just that it exports to JSON or Array or some format and store those map files inside your actual project to "Files/Maps" for example. Or if you use Node-Webkit then to their own file. To load new level, handle the loading process in the beginning and when loading a new level just restart the layout and point with global variable or something that which level will be loaded.
Also one option is to make your own editor. The plus on this would be that you can ship that with the game of course this would be much more work if you want to make it user friendly. I personally like this approach on large projects. It can also make some things a bit easier.
