How about making transform constraints to the sparkle bones so that they mimic the bones influence of the vertex you want to follow?

I also have the same problem.
I already have a project file in this topic but i don't know how to attach a bone to a vertex in mesh. Can u tell me

How to turn your 2d character looking 3D

P/s: sorry for my bad english :$

I've made a small project to display two ways of making an element follow two bones.
The first one is a bone that follows two different bones and stays in the correct place while the mesh deforms (the candle)
The second is the cream on top, which is made of many meshes that are binded to the two bones so that they follow it but without deforming. (very easy, it's just a bonus)

First we have the fact that the two bones match perfectly the corners of the mesh.
Then when we create the transform constraint we must remember:

• to press "match" so that the current bone position won't be changed
• the order of the constraints matters. The first one needs to be at 100
• the second we create will be at 50, so both the bones will influence the translation by 50 and 50

here's a gif of how the bone was set up (please note I pressed ctrl+z after the first time I set translate to 100, to show that if you don't press match it moves the bone around)

here's the superquick result:

and here you can download the source files to look at the setting (:

Hi Erikari, I got stuck when I could not attach bones to mesh, I did something wrong?

Try to do it as follows:

1. select the mesh
2. select the "Weights" tool
3. select "bind"
4. pick the 3 bones
5. select "bind" again to stop the binding
6. select the single vertices to adjust the weights on them

Here's the complete guide: http://esotericsoftware.com/spine-weights

@Erikari I have every mesh binded to a bone called bind1. works perfectly in the editor. But in my game I move bind1 at runtime. I was expecting everything else to transform with it but it doesn't work.

Is there a way to achieve this?

Hello Bilal! Could you post gifs/screenshots of how your setup works in the editor and in unity?
How is only one bone controlling all the meshes? Are you trying to make something in 2.5D?

@Erikari Hi! thanks for the quick response.

I use cocos2d-x
spineAnimation = SkeletonAnimation::createWithJsonFile("res/MainMenu/mainMenu.json","res/MainMenu/mainMenu.atlas");
this->addChild(spineAnimation,200);
Shared::rescale(spineAnimation, 0.75f);
spineAnimation->setPosition(winSize.width/2 , 0);
spineAnimation->setAnimation(0,"Entry",false);

bindBone = spSkeleton_findBone(spineAnimation->getSkeleton(), "bind1");

///on mousemove
//conceptually im doing this
mouseMove(){
bindBone->x = mouse->X;
bineBone->y = mouse->y;
}

I've tried calling update transforms etc. Is there anything that updates mesh transforms.

bind1 and bind 2 are bones that are binded to all the meshes.
