Confusion about the gt position change with action

[goodstudent9]

Great work! I want to follow it!

But I am confused about the {split}_gt.json when I look into the action_sequence.
First, you don't provide the lookup table about the action number to actual action. Like 0, 1, 2, 3(I know 0 means stop)
Second, there are no same positions in ground truth location sequence. But I just think, when you turn around, left or right, the position should be the same, right? But your gt json files don't show any same position between 2 actions.

Thank you for your answer!
