Minecraft singleplayer issue? - 1

Recently i have been having an issue where i can move and all in singleplayer but nothing else like i can't drop anything mobs won't react to me and i can't destroy blocks its like playing another game when the servers get shut down and you can still move around for like 2 minutes but interacting with anything won't work before getting disconnected.

i've always been in survival mode and this started happening after 1.7.10 i didn't have problems before does anyone else have this problem or does anyone have a solution. I've tried going back to 1.7.9 but didn't work.

Go to your library type %appdata% and press enter.

Go to your.minecraft folder and delete it.

Then go to minecraft.net and download minecraft again. This should work.
