Does AppGameKit support bone based 2D animation?

I want to make some characters, they can walk, jump, scroll, fight and so on. I wanna use bone based 2D animation, does AppGameKit support it? And How should I do?

You can create your own set of commands for Spriter or Spine. Both are currently Beta versions of animation software that can produce the effect you are after. I have a system I am using in a game I am making for TGC. There is a free version available here: http://forum.thegamecreators.com/?m=forum_view&t=197029&b=48&p=5

But that version does not export currently. I can send you a Beta version with a full Tier 1 command set if you like but as I said it is not 100% complete. Send me an email if you are interested.

Thank you very much! I use C++ and Tier2. So can you teach me how to make a bone based 2d animation system? I can write one in C++ by myself. Would you introduce some articles and books for me ?

I just made my own system up Halley, sorry I didn't use any reference material.

I basically use a sprite offset for the "top" of the bone and use a hierarchy system for moving "child" sprites when the "parent" sprite is moved / rotated. It can be very simple if you don't start adding the option to scale sprites too.

My own system produces a text file containing animation data. There are already a number of C++ libraries for Spriter and perhaps Spine that you might find more useful. I believe the intention is to include these libraries (or our own version) in AppGameKit eventually.

Hi Baxslash,
How should I use Spine data file into my game? I've no idea now.

I haven't personally used Spine I'm afraid. I am a backer but I haven't followed the project very closely as I have been too busy. If you would like a full version of my SpriteFX tool to try out I can provide some sample code (Tier 1) which would not be too hard to convert.

Spine, Spriter and SpriteFX will all produce a spritesheet if that is how you wish to work but they all differ in the animation data they produce. Perhaps if you email me directly with some basic details of your project I can point you in the right direction?

How should I use spritesheet? How should I connect the spritesheet and sprite in game?

Can your SpriteFX be used in the game?

Halley, attached is a simple project I have made using a character I made in SpriteFX. This is using a spritesheet. I will also try to post some code for using the animation system when I have tidied the functions up a little.

Making a character in the first place is the key to it. I will try to post a video soon.

I thought you gave up on that project. I am glad to see it come to life. I hope to see the project for sale soon.

No, I've been using and building on it. I still want to add a number of things before it is finished (or even fully usable). For example I want to be able to keep objects selected and have a couple of panels for hierarchy. It's getting there slowly.

That's good to hear. Best of luck getting every thing up and going. I did like what you have so far. I was working with it. I can see it will be a great tool. Maybe I should have waited before I bought Crazy Talk. None the less looking forward to your tool.
