SpectateLogin implementation #2745

Bagietas · 2023-08-31T15:09:50Z

Re-opened #2552 cause I don't have access to modify any of that.

Unit tests are missing
If the server crashes and players are not authenticated, players will be stuck in spectator gamemode (see comment thread in the original PR referencing "limbo player")

+    @Comment("Head Pitch position for 'spectateStandLogin'.")
+    public static final Property<Double> HEAD_PITCH =


I think this should work with the version of ConfigMe that AuthMe is using (please ignore this suggestion if it doesn't)

Suggested change

public static final Property<Double> HEAD_PITCH =

public static final Property<Float> HEAD_PITCH =

Also the naming is a bit weird, I don't know that RestrictionSettings#HEAD_PITCH refers to the spectate stand feature, and as a user I'm not sure I'll understand what this setting represents. Is it possible to elaborate in the comment? I would make a suggestion but I'm actually not really sure what the yaw & pitch settings are for

I don't know If i understood you correctly, but HEAD_PITCH and HEAD_YAW are under spectateStandLogin so It's obvious what are these settings for.

Thanks for changing the comment. I also meant the field name, RestrictionSettings.HEAD_PITCH in the code sounds very generic. Could we maybe name it SPECTATE_HEAD_PITCH, or maybe you have a better idea?

Potential null pointer if the plugin crashes before this service is set on L251

The proper way to do this is to not have the field, but to use another method from the injector (not sure what methods exist by heart, but if there's something that returns a singleton if it's been registered, that would be it, otherwise maybe injector.createIfHasDependencies though it's not ideal to still potentially create it at this point)

The field on the class is no longer needed (an IDE shows an unused warning)

injector.createIfHasDependencies(SpectateLoginService.class) might return null, so the issue of a potential null pointer still remains. And I think it would be better to use injector#getIfAvailable

+            || spectateLoginService.hasStand(event.getPlayer())) {
+            // If a player is dead, no stand will be created for him
+            // therefore we can be sure that there will not be two stands
+            bukkitService.runTaskLater(() -> spectateLoginService.createStand(event.getPlayer()), 1L);


I can't confirm the comment about stands not being created if a player is dead but maybe I'm missing the relevant point, but interestingly the logic here specifies a stand should be created if the setting is enabled, or if the player has a stand? I don't think that makes much sense.

Removed unnecessary comment.

Now an armor stand is created for a player every time he respawns, regardless of whether an armor stand already exists or not

Unit tests are missing

What do you mean by this? (Never used tests)

If the server crashes and players are not authenticated, players will be stuck in spectator gamemode (see comment thread in the original PR referencing "limbo player")

Implemented it.

Unit tests are missing

What do you mean by this? (Never used tests)

Every class has a "Test" class associated to it, e.g. BukkitService has BukkitServiceTest. These are unit tests, which ensure that refactorings and similar don't break things in unexpected ways. Searching for JUnit should also provide additional information.

If the server crashes and players are not authenticated, players will be stuck in spectator gamemode (see comment thread in the original PR referencing "limbo player")

Implemented it.

I think it would be important to test different scenarios, like if existing limbo player data exists before these changes, there might be limbo player data already stored on disk. Since no "gamemode" exists, it's null, which I think will cause further issues down the line when we try to set the gamemode to null on a player. I don't fully remember the whole lifecycle of the LimboPlayer (and I'm going abroad soon, so a little pressed for time this week) but I think this would be nice to really test in detail to make sure this won't break players' data.
It might make sense to only touch the gamemode if the player is currently in spectator mode, the spectating setting is enabled, and we have another gamemode on the limbo player. Or maybe to have a config like we have for many of the other limbo stuff to allow it to be enabled and disabled. Someone else from the AuthMe team might have some good inputs here.

Your code doesn't compile btw

It's my first time I do something like tests. That's my try to implement it but I don't know if it's correct.

If I understood you correctly I've added what you've meant.
