Release: 4 years ago
This week we are releasing a bit of a smaller snapshot. However, if you're into switching game modes and completing advancements, this is right up your alley!
Edit: We've now released 20w20b to fix a bug
Fixed Bug in 20w20b
- MC-183769 NPE in server initialization
New Features in 20w20a
- Added new Game Mode Switcher debug menu
- Added new Nether Advancements
​
Game Mode Switcher
New F3 debug feature which allows you to switch game modes with traditional "tabbing" functionality. ​
- Hold F3 and tap F4 to open the menu
- Tapping F4 will cycle the game mode, or you can use the mouse
- Release F3 to apply
- Your last game mode is remembered and will be the first selected option, so you can quickly toggle between two game modes with a single press of F3 + F4!
​
F3 + N (Toggle Spectator)
A small change has been made to this debug combination. ​
- By default, using this key would return to Creative after toggling from Spectator. It now will toggle back to the previous game mode you had.
- As an example, if you were in Survival, then toggled to Spectator and back, you would be set back to Survival.
