Changing file used for sprite object at runtime

[TravisGesslein]

Is it possible to change the file used by a sprite object at runtime and have the spriter.js animation reflect the change in pivot points, etc.? Ideally without using character maps, otherwise you'd have to create a character map for every image you want to change (we would like to switch out weapons, armor and stuff like that individually).

After some experimentation, a hacky way of doing this is to swap the file objects in the folder_array[...].file_array arrays before updating a pose, swapping out the file used by an animation with another file. This seems to work since the Spriter.js code only seems to care about pivot and sizes of these files, but it's obviously error prone in case the library updates and the above isn't true anymore (for example, right now the library code seems to access the file directly, a future update might cache the file data somewhere else instead so swapping out the files doesn't do anything).

So for me the procedure right now when animating entities in game is to swap in the correct files before each pose.update(...) call (otherwise all entities that use the same animation will use that particular picture you swap in, which might not be desirable), and swap back everything to their default positions after updating the animations of all entities.

Would be cool if there was official support for this in the library that allows switching out images in poses (so you can create a pose for each different in game entity and each can have a different set of images used for all of the animations in the poses), individual animations (so an image is only swapped out in a particular animation) or the entire entity (so you can change the 'default' look, so to speak, at runtime), or combinations of these (such as changing the image only in a specific pose in a specific animation).

Character maps sound similar to this, but I'm not sure if there would be an easy/fast way to define them at runtime, and I also don't know how to switch to a different character map for a single pose in Spriter.js.
