isSprinting() and setSprinting() methods dont work correctly,

[Dueris]

Expected behavior

Im able to check if a player is sprinting, and set if they are sprinting.

Observed/Actual behavior

Both do not work. If I check if the player is sprinting and I am sprinting, it returns false. it seems the client and server are somewhat out of sync when it comes to this, since after using setSprinting(boolean), the isSprinting() method is updated.

Steps/models to reproduce

Just run either of those methods anywhere, it wont work correctly.

This is likely just going to be the caveats of "player movement happens on the client"

[Dueris]

However the client updates the server, so shouldn't it judge if the player is sprinting?

[Dueris]

What abt the PlayerMoveEvent?

[electronicboy]

it doesn't judge if a player is sprinting, as far as the server is concerned it just sees movement from the player. The question here is, does the client tell us if the player entered a sprinting state?

[TonytheMacaroni]

I've tried both Player#isSprinting and Player#setSprinting, and both methods seem to work fine. Are you testing this with a vanilla client?

The question here is, does the client tell us if the player entered a sprinting state?

The client does communicate when it starts/stops sprinting using ServerboundPlayerCommandPacket, and the value is set server-side using that packet.

I ended up finding the time to look,
So, the client does tell is when it enters/exits sprinting mode, it does add a modifier but also sets the general entity flag which is what isSprinting checks
