At the moment FloatingTextComponent is visible through the world. In some cases, this is not helpful and a lot of floating text can clutter the screen. The task is to add a flag to the FloatingTextComponent called isOccluded that allows text to hidden if it's obscured by something in front of it.

The Minesweeper mod is one such case. Each numbered block that is mined leaves a floating number. This both clutters the game and makes finding mines a frustrating challenge. Once you have added the flag it should be enabled for the FloatingTextComponents in this repo.

Definition of 'Done'

• Tweak Renderer so text is hidden behind other objects in the scene
• A screenshot attached demonstrating that the text is obscured correctly ( You can use the Minesweeper mod to demonstrate this.)
• Pull request submitted to the Terasology repo
• Pull request submitted to the Minesweeper repo

Where to start

• Add a boolean flag to the FloatingTextComponent called isOccluded
• Modify FloatingTextRenderer so that the isOccluded flag is taken into account.
• Look under MinesweeperSystem at the onCounterDestroyed method
