API documentation

FinchVR is the main Finch Unity API class that provides all controller's functional. It is necessary to have one and only one FinchVR script instance on the scene. Use prefab FinchMain to do that.

FinchSingleControllerPlayer and FinchDualControllerPlayer scripts allow to move controllers and head according to Finch controllers position. Use prefabs FinchSingleDashController, FinchDualDashController, FinchDualShiftController for that. Don't use more than one same script on scene at the same time.

AvatarIK script is default way to use standard Unity inverse kinematics. Use prefab FinchAvatar for that. Don't use more than one same script on scene at the same time.

Remember: Finch API use settings form FinchSettings. Default settings can be unsuitable for you, so edit settings right after creating your Finch Unity project.
