(Resolved)I require a little help on my project.

[Doomforger]

I am new to the Love engine and i'm working on a game that is similar to an Atari game, but i can't seem to get states to work correctly, i want to reset the game and take you back to the menu on defeat but it seems i am doing something wrong because it just takes me back to the game screen that says defeat on it. I'll post what i have here and hopefully someone can help, thanks for reading.

Could you post a .love file of your project?

[Doomforger]

Could you post a .love file of your project?

Keeps giving me a error 413 request entity too large.

[Spec0pAssassin]

I believe that error is beyond my expertise but maybe you could post it some other way like a link to a dropbox download if you have an account there?

[Doomforger]

I'll keep messing around with it until I figure it out or someone posts the solution on here then, thanks for trying spec.

[Spec0pAssassin]

No problem, sorry I couldn't be more help. But again from what I understand you just need to figure out a way to clear/reset what was being drawn last or something along those lines.

[rexjericho]

If you want to reset the game to a state that is identical to when you first open your love file, I believe you can simply just execute the function:
love.load()

Thank you, it worked after some tweaking to my love.load().
