DoubleJump / Knockback

[callum5771]

Describe the bug

Our network proudly uses Geyser to support Bedrock players, we've updated to the latest version of Geyser today and found that the Double-Jump plugin we use works fine on Java (as it had previously) but not on Bedrock, instead of performing a double-jump, the player simply can fly around the lobby freely and no double-jump is actually done.

This worked fine on Build 218, but the update to Build 237 has since broken this functionality. We use Geyser for Velocity and run Floodgate on all Spigot servers behind our proxy, not not Geyser, Geyser only runs on Velocity on our setup.

Plugin in use: https://www.spigotmc.org/resources/infinitejump-double-triple-infinite-jump-1-8-1-20.51522/

To Reproduce

1. Make a Paper 1.20.1 server with InfiniteJump installed, default settings will do just fine.
2. Go into survival mode and attempt to double-jump on Java, you should see it works fine.
3. Go into survival mode and attempt to double-jump on Bedrock, you should fly instead.

Expected behaviour

The player should double-jump, they should leap into the air for a second or two, and come back down again.

We have the same issue. After a small test by myself I noticed, that the PlayerToggleFlightEvent won't be called for bedrock players on some devices. I tested it myself with an Iphone, Ipad and the Windows 10 Edition on a computer. On the Iphone and on the Ipad the PlayerToggleFlightEvent didn't get called. On the Windows 10 Edition on the computer it was called.

The PlayerToggleFlightEvent is important for any double jump plugin. Can be seen in the source of ur linked double jump plugin: https://github.com/MrMicky-FR/InfiniteJump/blob/master/src/main/java/fr/mrmicky/infinitejump/JumpListener.java

Hope this helps to fix it 👍

@callum5771 please try updating to the latest version of Geyser; #4001 should resolve this.
