How to add new Pant to the existing character.

[eklavyaa]

I have a character with 10 frames. I have created a sprite collection for these 10 frames and using 2dtoolkits own animation I am animating it.
I understand that atlas is created for these 10 frames .
Now I want to change the appearance of the character say I want to apply new pant. How I can do it with minimal efforts, I mean do artist really need to develop another character with new pant and its 10 frames ?

You can draw clothes on a separate sprite and draw it on top of your character sprite if you want. tk2d doesn't have any special features for this apart from the sprite attach points.

How to do it ?

What I was thinking is to change texture of the legs from current to the texture of pants , for all the 10 frames and then create atlas for these 10 frames to create animation and this will be done only when pant is finalized as the selection .

 Can this be done programmatically ?

You can do it using GetPixel / SetPixel with Unity textures.

So using these function if I want to change the shirt of the character: I will read the pixels which represent the shirt  , then set the pixels of selected shirt on this existing shirt .

But how to detect , which pixels represents shirt ?
and
how to get UV coords of these pixels ?

That is outside the scope of tk2d, you'd probably need to store that in a format you can read, and write out the atlas suitable for tk2d.
