Join the Discord: https://discord.gg/4tHeAkxNg7 In this episode I expand on the gizmo that we were creating in the previous episode. We implement the functionality so that the translate gizmo actually translates the objects, then we refactor it to be easily extendible and create a scale gizmo using the same code. I also go over how to create proper mouse drag event detection, and add the proper mouse dragging into the event handler. And finally, I add a gizmo system that allows the user to switch between gizmo modes (translate, scale, etc) and then manipulate the active game object in different ways.
