- Inventory Menu To open the inventory, click the HUD bar at the top, or press Q. This version is for testing. If you want to test it with the real version, you can bring the sprite over. It may unpause while the inventory is open because of redundant scripts. -HUD Bar The HUD Bar contains all of the HUD elements, like health, and when the pause screen is opened, it gets moved to the bottom. There is one element in this version, as a demo. It was inspired by the HUD Bar in Fantasy Land. -THIS IS A UI TEST! There is no function in this version. This is my UI demo.
