Hello everybody and today I will show you all how to change from survival to creative in Minecraft with cheats disabled! Basically all that you have to do is open your world to lan and click cheats enabled, now cheats are enabled and then you just type “/gamemode creative” and it changes. If you then quit the world cheats will be disabled again because it is not open to LAN anymore. So what you have to do is open the world back up to lan and enable cheats then type “/gamemode survival” and it goes back to survival.
Please leave a comment on what tutorial you want me to do next!
A quick summary of survival mode from the wiki:
Survival mode is the main game mode of Minecraft in which players must collect resources, build structures, battle mobs, manage hunger, and explore the land in an effort to survive and thrive!
In Survival, you have an inventory where you can gather items nececsery to survive. These items may be combined using certain recipes to create tools and other items. This process is known as crafting. Most crafting recipes need a crafting table but if you are in creative you don’t need to craft you can just get it in your inventory.

A quick summary of Creative mode from the wiki:
Creative mode is one of the main game modes in Minecraft. Creative mode strips away the survival aspects of Minecraft and allows players to easily create and destroy structures and mechanisms.
Creative mode allows players to destroy all blocks instantly (including normally-indestructible blocks such as bedrock) and the ability to fly. The only possible ways to die without the use of external tools are to use the /kill command, or to fall into the Void. Players are given an infinite number of blocks to build with and no health or hunger bar thus rendering the player immune to all damage. Taking advantage of this, players can create large constructions more easily.
