Let's say in studio I pressed play and added a few things, if I press reset, they will be gone, how do I save what I have currently because you can't save when you press play unless you press reset
This is the wrong forum for that, This is for pepole who will build for you, Not for help with errors.
You cant save anything that you do in test solo / play solo, Unless you go in 'Build Mode' Test solo / play solo is a test mode, Anything done in there will not save. If you wish to intreract with your player in studio + get the bars, Then go in ROBLOX STUDIO (only this) then do NOT SWITCH TO CLASSIC, Basicly just go to the project, Click it and then click 'Build', Dont do this on the site / in classic view mode or it wont work. This will work.
Note; The game must be published to roblox.com and you must be useing the publisher's account.
