Now that we have a template selected and the project settings set up the way we like, we can create the project. To do so, click on the green Create Project button. After the engine is done with initializing the assets and setting up your project, Unreal Editor will open Level Editor, where you can create and view Levels, place and modify objects, and test your game as you modify it.

Pressing the Play button—as shown in the following screenshot, located in the toolbar—allows you to try the default gameplay that is built into the First Person template. This includes player movement, shooting a simple projectile, and using projectiles to apply force to primitive box objects. In play mode, the Play button will be replaced with a Pause button and a Stop button. You can press the Pause button to temporarily halt the play session, which can be useful when you want to explore the properties of an interaction or Actor that you have just encountered during gameplay. Pressing the Stop button ends the play session and takes you back to editing mode. Go ahead and try playing the game before we continue:
