Multiple sprites in a single frame??

[bon]

Can I add multiple sprite in one frame?

I have a large building texture, and I only want to make animations at its small parts in order to save the memory for texture.
Can I do this in 2d ToolKit?

Thanks a lot!

2D Toolkit 2.1 hashes individual tile chunks when dicing - it will remove duplicates when it finds them. Animating these isn't as efficient as animating normal sprites, but you could save quite a lot.

One caveat - this isn't a solution to make video, for instance You couldn't throw 1000s of frames with tiny bits moving in there - it will run out of memory building the atlas. It will also take forever.

Maybe you misunderstood my question? Let me clarify it a bit more.

I want to make an animation with more than one texture in one frame, like the picture below (ignore the skeletal animation).



In this way I can make 1000 animation for a character without using more than one set of texture.

So if you're not doing the skeletal animation, what exactly do you want to do with all the articulated parts? How do you want to animate them?

[bon]

If every frame of the animation can have multiple sprite, I can edit them frame by frame.
I wanna know whether 2d toolkit support this.

No it doesn't - but you could code it yourself. One frame of animation can only have one sprite.

Edit - you could also sync multiple animations together if you wanted to, that will be easy enough to code in there.

In a similar vein:
Is there a way to stack multiple sprites into a single prefab/gameobject? If I wanted to make a character that's made of a number of "parts" but each part is a single sprite, is there a good way to create a natural grouping of sprites? For example, in the OP's picture above let's break it into 4 pieces: head, arms, body, legs. I'm wondering if there's a way for me to take those sprites and link them into a single unit that I can use elsewhere instead of having to copy/instantiate those 4 pieces every time. I think using that method you could create code that would swap out the sprites to create your "animation."

I tried adding multiple Sprite components to a single object, but that didn't have my intended effect. Is this possible to do?

Sorry if this isn't inline with your topic, OP. I think they're similar enough problems that I didn't want to split it off into a redundant thread.

Why not just create a prefab of the root object, you won't need to instantiate 4 pieces every time?
You can't have multiple sprite components on a single object - it relies on a meshfilter, and there can be only one of those on a component.
