Yeah, sorry to be causing so much of the feature creep, whenever you feel like you've hit a "final" version just post it up, and say "no more"

OK, cool
I'll keep checking back as it looks really good.

What in particular runs slowly? Just clicking and moving the bones around or animating between frames?

If it's the animating then it will be a bit slow at the moment the delta for the interpolation is just supplied by a 'for' loop as opposed to based on the actual time passed. Under options there's an option to take out the 'rest' that's in the for loop to run it as fast a possible but it still will try and do a set number of interpolations. I'll make an option to change this number in the near future as a temp fix.

In the actual game engine the delta is calculated the proper way based on actual time so it all works perfectly but I just have to code it that way in the editor. Won't be too differcult as the skin animations do it properly already but they were just an 'Animation' class I'd already written dropped straight in (took about 1 minute!). Same class that's used in the game for non-skeletal entities, tiles, and other graphics.

Masked rotations using Allegro's software routines at 800x600 isn't the greatest and there's a lot of calculating being done each frame using Sine and Cos. There are already lookup tables for these but I'm still tweaking them to get the accuracy right so in the meantime it's just being done with the actual functions. My actual game engine runs using Openlayer with alpha blended rotations, and is much faster. After all that, optimizing will be in order sometime but one thing I've learnt is to get it finished and working THEN optimize or it might never get finished.

it works for me... and I love it so far.

Couple of issues though:

1.) When I change frames, all the changes I made to a frame are lost when I go back to it... what happend?

2.) Why does add frame insert a frame before the one I'm working on instead of add one after it?

3.) When I play the animation, the buttons to stop or control the animation become unresponsive, what the heck?

4.) Why do the textures have to be in png format?

5.) Can we get some kind of tooltips so that when I hover over a pretty icon that I don't know what it does, maybe it can say something to tell me what it is? Even in a status bar at the bottom of the window would be nice...

Finally: How soon can we expect a bmp-out feature? (or png-out, since you seem to like that format! )

Edit: Also I've been playing castlevania:SOTN lately and a LOT of the bad guys are actually vector based (and that evil dino bastard is one of them). Blah.
