As the title says, I wanna know how to save data for tools like when player left the game and then rejoined they will have all the tools they have before they have left the game. I’m very new to script and this is a very big issue for me. I tried all the freemodels i found from youtube but they seems to not working, I do everything the same as the video but i dosen’t have the same result as them. So if you know how to save data for tools pls let me know, btw teaching about DataStoreService or give a very simple explanation will be very great too.
