Assuming i was to make a 2d physics game with unity and it was to have mp3 files as the sound files and some .wav files as sound files where would i start?
Best place to start, would probably be right here: Learn
ok but say i wanted a level map and stars and timer and stars out of 3 maximum for each level finished with in the level and the level map on the level icon, and i wanted to add retry button and continue button, but having 1000 objects for all that for a mere 500 levels could result in a game crash, how would i abort the crash? Also i do not how to switch modes of creation of a game from 3d to 2d… Oh and i would like to know how to use the built in particle system for part of my game…
Edit: sorry i should have said 3d to 2d
Spend some time on the Unity Learn site. Complete a few small games, even just some prototypes, to gain a better understanding of both Unity and game development and you’ll come to understand how to lay out your project and scenes much better than what you’re seeing now.
thank you, very much…
I think you are focusing on the wrong ideas first. Start your game really small. No graphics, main menu, HUD, particle systems, etc. Just build the gameplay mechanics and it will take off from there. Also, please do spend some time on the Learn section of Unity so you can learn more about the engine. Thanks and good luck 
Hi i cannot find the bounce material any where on the 2d asset store or the unity engine can someone please give me a link to that, cause i know how the basics work now. Oh and also not to seem snarky but i have watched the learn videos 15 times already now, ok… Now i know its meant to have a menu but i dont know how to create button objects for the game yet, however if i did i would implement the menu so once teaches me how to make a simple clickable button i will make the menu. I am also thinking about a detailed in depth story for this particular puzzle game and it shall be called “Feed The Alien Pizza” note this is not related to “Cut the rope” or any other game on the store, and yes it will have 30 levels in the demo and 500 in the full version that is ten worlds of 50 stages.
Physics materials are created by you from within the editor, the online documentation and manual do a great job explaining most things. You can also find the documentation for the methods contained within the base MonoBehaviour class which contains a method OnMouseUpAsButton which can be attached to your GameObject in the scene, these two combined can be used as the basis for your button.
