Removing Components and Data Storage

[BinhTran17]

Hi, I have 2 other questions regarding SofaUnity:

1. My simulation has a FixedProjectiveConstraint component. When I comment it out in the .scn file, my object falls down as expected from the gravity. However, when I manually delete it from Unity's Hierarchy OR use SofaBaseComponent.DestroyComponent(true), nothing happens and the object is still constrained.
2. Based on my inspection, the data values with type vector<Vec3> and similar are not stored, there is only a placeholder for the array of vectors. This is shown in lines 108-135 of SofaDataArchivers.cs.

Hi,

very good questions. So:

1. Yes this is normal because the Unity Component object are just mapping what is present in the .scn file. Removing the unity GameObject will just remove the "API interface" to interact with the SOFA component. It will not remove the component.
2. Yes, this is because there is no easy and efficient way to display a Vector of Vec3. However you can still access the Sofa Data in read and write mode:

   SofaUnity/Core/Scripts/Core/Data/SofaDataVector.cs

   Line 261 in d022d30

   public class SofaDataVectorVec3 : SofaDataVector

Hi @BinhTran17
were you able to access the Data as expected?
