The openage converter is able to optimize the compression for created PNG files by utilizing a search algorithm inspired by OptiPNG. To do this, the search algorithm first tries 8 different compression settings by creating PNGs with these settings in-memory. The compression settings that produ

We should refactor the way we handle opened UI panels. The code for this is in d2game/d2player/game_controls.go. In particular, look towards GameControls.onEscKey.

I am thinking that we should implement a stack in GameControls for managing the panels.

It could be used like this:

type panel interface {
	IsOpen() bool
	Close()
}

type panelContainer interface {
	HasOpen

Currently, if credentials are in use, they are authenticated in the master’s onUpdate method. For example:

However, this is not the case for onSync or the new onConnectionChange (#839) methods, which presents a potential security flaw. If a match is using credentials

We moved from Jenkins to GitHub Actions for CI in amethyst/amethyst#2382 -- we wanted to ship that so we can get CI working in general for folks again. Here's a list of other things we would like to do soon. Please comment if you have more ideas!

Each item should have individual issue(s) and/or PR(s) opened for them. Let me know in a comment and I'll add a link next t

In #3571 we add a system to track AFK status for players.

This is a suggestion to simplify the implementation of AfkAuthoritySystem.java by removing the internal field count. As noted in MovingBlocks/Terasology#3571 (comment) I'm not sure whether this is actually required. I'm wondering whether it would also work to just rely on the entity information we
