Multiple Bone

In DOTS Dynamic Bone a Multple Bone is associated with entities that contain the DOTSDynamicBone_BufferElement DynamicBuffer. The DOTSDynamicBone_BufferElement data can be modified at any time.

The DOTSDynamicBone_BufferElement contains all the DOTSDynamicBone data as well as 2 int value that represents a start and end index respectivly.

the start and end index data is used to get the relevant Particle data within the DynamicBuffer<Particle>. So to access specific DOTSDynamicBone_BufferElement data's Particle data you would have to do something similar to this:

    ...
    DynamicBuffer<DOTSDynamicBone_BufferElement> bones = GetBuffer<DOTSDynamicBone_BufferElement>(RigComponentEntity);
    DynamicBuffer<Particle> particles = GetBuffer<Particle>(RigComponentEntity);
    for(int i = 0; i < bones.Length; i++){
        DOTSDynamicBone_BufferElement bone = bones[i];
        DOTSDynamicBone boneData = bone.Value;
        for(int j = bone.start; j < bone.end; j++){
            // deal with particle stuff in here
        }
    }
    ...
