[Reviewed] [Multiplayer custom lobbies] Customize the interface of multiplayer lobbies

[github-actions]

Description

Custom lobbies for built-in multiplayer.

Customize the interface of multiplayer lobbies.

Joining will only work if the "join after game starts" setting is enabled, as the game automatically starts after joining a lobby.

How to use the extension

This extension contains a custom lobby list object, just add it to the scene and everything should work, make sure the project is published at least once (eg on gd games) and the "join after start" option is enabled.

Thank you for submitting an extension.

I have some suggestions:

• You can use the panel sprite button extension. Extensions dependencies are allowed for custom objects because required extensions are installed automatically with the asset.
  • The button variant don't need to be in the asset store. It's embedded into your asset.
• MouseWheelDelta() should probably be used for the scrolling
• Mouse wheel is usually proportional to a scroll offset, not the thumb offset (which is dependent of the content length)
• The "for each instances" in doStepPostEvent seems not to be necessary
• Should "Activate Button FSM behavior" be renamed "Activate interactions" or something like this?
• The "Setup" action is private so I guess it's fine, but, usually, it's better to have separated setters to be able to be able to:
  • hide them for compatibility when they no longer make sense
  • make some parameters optional (no call to the setter meaning "keep default value") especially the new ones that may be added in the future.

[Jurfix]

• The button has been replaced with a custom object from the Panel Sprite extension.
• MouseWheelDelta() is taken into account when scrolling with the mouse wheel, and the list is now shifted by the height of one row per scroll.
• Unnecessary "for each instances" have been removed.
• The "Activate Button FSM behavior" action has been renamed to "Activate interactions".
• The "Setup" action has been split into separate setters.
• Added a visible "Lobbies Y offset" parameter to the "CustomLobbies" custom object.

I will try to make a pixel-art example and do some additional changes for this.

Changes

• Extract the scrollbar into a custom object
  • [Community] [Scrollbar] A scrollbar to help making a scroll view #1827
  • Extension creators will be able to build a scroll view more easily
  • Users will only have to create one scrollbar variant that they can use in all custom objects

It looks good to me. You can do a final check if you want.
