Thank you everyone for your interest and purchases.
inkBot - yes, this is a pro only feature called a Character Map. The version of the editor releasing soon will not include all pro features as of yet. All the plugin code is there to support it for the Construct Classic version, and for projects converted from the old spriter, those charmaps will work. It should be less than a month after this release before you start getting the extra pro features in the editor, one at a time. The first one, 'export to PNG', will be available in this release.
As for charactermaps, your images will be divided into folders (manually on your hard drive. edittime folder management, or a virtual folder management system is on the todo list). You could have one directory "/Robot Arms" and another one "/Human Arms", containing files with the same names that correspond to eachother. Each character map lets you specify any number of folders, and whether to display the images in that folder normally, don't display them at all, or choose an alternate folder to retrieve the images from when that character map is applied. This allows for a wide range of uses. You could of course make a total conversion so characters could look completely different with a whole new set of sprites. But you can also make one version of each animation for your character, and have an event such as:
On SpriterCharacter collision with ClothingFamily
----Set SpriterCharacter charmap to ClothingFamily.PVNameOfCharmap
----ClothingFamily : Destroy
Each charmap could specify folders containing those articles of clothing. So now your character has a hat, or a helmet, or shirt, or armor after touching the powerup, any number of sprites could be added removed. or replaced. All without having to touch the animation(either in the events, or in the editor).
There are several planned enhancements on the todo list such as having multiple charactermaps applied at a time, and also, I'd like to add Charmaps that are definable at runtime, so you could basically define a modkit with simple actions that allow the user to choose a different folder to grab the sprites from. This way they could make their own character models, or whichever things you want them to have control over. This feature will probably be available when the C2 plugin arrives.
Also, eventually I'd like to add granular control like Replace RightArm.png with SomeOtherRightArm.png.
