This Unity tutorial will go over how to create and script a UI speedometer for our motorcycle. The motorcycle may look familiar as it was taken from the fantastic Blender course by Chris Kuhn found here: Modeling a Motorcycle.

C# will be used to control the increase and decrease in speed. It’s fairly simple and straightforward but looks really cool and can be applied to a lot of different game mechanics.

By the end of this video you should know how to create this:
