よくあるミス
ミス:
Switching to survival while high in the air in creative mode
修正方法:
Always check your surroundings before switching modes - you'll fall and take damage in survival!
ミス:
Typing /gamemode without specifying which mode
修正方法:
You must specify a mode: /gamemode creative (not just /gamemode)
ミス:
Trying to use spectator mode in Bedrock Edition on older versions
修正方法:
Spectator mode is only available in recent Bedrock versions. Use creative mode with /effect @s invisibility for a similar effect.
Java版と統合版の違い
Java Edition has full Spectator mode support with special features like viewing from mob perspectives. Bedrock Edition has limited spectator mode, primarily for observing.
便利なヒント
You can use shorthand: /gamemode c for creative, /gamemode s for survival, /gamemode a for adventure.
Switching to creative mode gives you instant health regeneration and immunity to damage.
Adventure mode prevents players from breaking blocks without the proper tools - perfect for maps.
Use spectator mode (Java) to scout areas or preview builds without physically being there.
Game mode changes are instant - your inventory persists when switching modes.
重要な注意事項
Bedrock Edition does not officially support Spectator Mode in the same capacity, though it was recently added as an option (`spectator` or `/gamemode 6`). Numbers (0=survival, 1=creative, 2=adventure) are deprecated but may still work on Bedrock.
よくある質問
Do I keep my inventory when changing game modes?
Yes, your inventory stays the same when switching between game modes.
Can I change someone else's game mode?
Yes, if you have operator permissions: /gamemode creative PlayerName
What's the difference between Creative and Spectator mode?
Creative lets you fly and build with no restrictions. Spectator lets you fly through blocks and observe without interacting - you can't place or break anything.
Why can't I break blocks in Adventure mode?
Adventure mode is designed for custom maps. You can only break blocks with tools that have the CanDestroy tag.
