As explained here: https://forum.gdevelop-app.com/t/jumping-behaviour-not-working-as-expected/26011/8
A jump speed of 0 triggers the same issue. The jump flag is triggered and the player cannot jump anymore once the jump speed has been reset to a normal value.

@Bouh @4ian This seems to be unresolved and has shown up again on the discord. Can we get the title of this changed to "Unable to jump if once changing jump speed back from 0" or something similar if there's a better title?

@Silver-Streak I've invited you to be a collaborator so that you can triage/rename/label such bugs :)
@arthuro555 I've done the same for you - as you're both regular contributors/active in the community.

Please use only these rights to triage/rename/label issues - I unfortunately can not grant a "triage" permission as the repo is not yet in an organization :)
Continue to open Pull Requests for all code related work (no push to master, no push to branches, keep using branches on your own repositories to ensure I can keep the stability of the main branch and validate the changes coming in).

As for the bug, we should avoid going at all in the jump state if the jump seed is 0 indeed!

@Silver-Streak Do you know if this bug is still alive?

I am not able to reproduce this any longer. I wouldn't be surprised if some of @D8H 's changes to the platformer behavior fixed it over the past few months.

Considering as fixed then, I guess the refactorings notably the move to a state based logic helped! :) Thanks both for checking!
