I'm a programmer working on a 2d double dragon style fighting game, where I store my sprite clips and hitboxes in xml.

Is there a tool which lets me specify the sprite image and the output file so that I can visually draw hitboxes on the sprite and get the output rectangles? (Not necessarily the exact same format, if it's open source I could modify it).

Here's what a single frame of my game looks like: (clip is the sprite clip, box_v is vulnerable hitbox (hurtbox), box_d is damage hitbox)

Code:

<frame>
<!--When sprite is facing left-->
 <left dx="0" dy="0">
   <clip x="200" y="3000" w="200" h="200" />
   <box_v x="71" y="14" w="74" h="172" />
   <box_d x="0" y="0" w="0" h="0" />
 </left>
<!--When sprite is facing right-->
 <right dx="0" dy="0">
   <clip x="200" y="2800" w="200" h="200" />
   <box_v x="54" y="14" w="74" h="172" />
   <box_d x="0" y="0" w="0" h="0" />
 </right>
</frame>

Link to video of hitbox tool similar to what I'm looking for (this is just a viewer afaik)

My current workflow involves me drawing hitboxes on the sprite sheet in paint.net, and then manually inputting values for each frame. This can be rather...taxing on my sanity (not to mention very inefficient), I'm hoping there's a better way to do this.

Any help would be awesome.
I searched the forums for this but didn't find anything, pardon me if it's a repost.

In all honesty, it'd be pretty easy to write this tool from scratch(especially if you already have a renderer and image loader).  I'd suggest create a new "mode" for your engine(which could be flipped on via the command line: edithitboxes ./path/to/file.jpg) and then just catching the mouse click/drag to draw a box.  For bonus points, you could catch the mouse wheel to get a little zoom going.  Everytime a box is drawn, output some static XML file(possibly named HitBox.xml).

The approach would work for a very simple hitboxes, but I've got about 8 frames like the one I mentioned for each animation, and about 20-odd animations for a single character. Without a proper tool to play/pause through animations frame by frame, this method won't work very well.

Making my own tools is a last resort, but I was thinking that there has to be an existing tool or project I could use and/or contribute to. With all the games being made, somebody better than me would have dealt with this problem by now
