Set qfrc/xfrc in Unity

Discussion in 'Unity Plugin' started by ksjoey0096, Sep 18, 2018.

  1. Hello,

    There are some questions I want to ask.

    1. Since there are only the function names in Unity Plugin, can I know what SetPerturb(TPerturb* perturb) actually do in Unity?
    2. How can I directly control the mjdata, or how can I add functions like qfrc_applied / xfrc_applied to Unity Plugin?

    Thanks

    You cannot control the simulation except via mouse perturbations. This limitation will be removed with the next update of the Unity plugin -- sometime in December or January.

    SetPerturb sets a mujoco-specific data structure with information about mouse selection and perturbations. It can only apply force and torque to a single body at a time, and cannot be used as a general control mechanism.
