# Objective Make the examples look more uniform and more polished. following the issue #17167 ## Solution - [x] Added a minimal UI explaining how to interact with the examples only when needed. - [x] Used the same notation for interactions ex : "Up Arrow: Move Forward \nLeft / Right Arrow: Turn" - [x] Set the color to [GRAY](https://github.com/bevyengine/bevy/pull/17237#discussion_r1907560092) when it's not visible enough - [x] Changed some colors to be easy on the eyes - [x] removed the //camera comment - [x] Unified the use of capital letters in the examples. - [x] Simplified the mesh2d_arc offset calculations. ... --------- Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com> Co-authored-by: Rob Parrett <robparrett@gmail.com>
