after creating my map I began the works on setting up my game mechanics, checkpoints etc. I've created 2 new folders, one named Audio, second one named Blueprints.

inside the audio folder I have added 2 sounds which i got from this website; https://wiki.unrealengine.com/File:TimeAttackSounds.zip

I then went into the blueprints folder and created 5 blueprints and named them, I'll need those in order to make my game functional.

And finally i made the last folder named UI in which I created a widget blueprint and named it HUD, this will be my HUD for my game
