How do I get my project back to a third person project? It's forcing me to noclip around for no reason

I’m guessing you created your Game Mode earlier while following the videos?If you did then go to World Settings and select your game mode.

I’ve been working with this tutorial set for a while and stopped at video 15. I opened my project again today to continue and learn the animation montage system but I can’t because my 3rd person project is like a noclip project now. When I hit play last night I could run around in third person but not anymore. all i can do is fly around floating in the air. how do I get it back to third person? Thanks.

That did it! Thanks!
