The structure here is good, just needs some cleanup. Files should also be using tabs instead of spaces.

You can use the worldguardregion classinfo here

+    @Override
+    public String toString(Event arg0, boolean arg1) {
+        return "WorldGuard region flag";


the toString should represent the actual input of the user
ex: flag <flag> of <region> (take a look at some of the other syntax elements too :))

+        WorldGuard wg = WorldGuard.getInstance();
+        RegionContainer container = wg.getPlatform().getRegionContainer();


Can these be put in static fields instead of getting them each time? Not sure the details on WG's API, so just a question.

Use event instead of e everywhere

Suggested change

protected String[] get(Event e, WorldGuardRegion[] region) {

protected String[] get(Event event, WorldGuardRegion[] region) {

+import java.util.List;

Can we create a classinfo for WorldGuardFlag? if so this expr should return WorldGuardFlag classinfo instead of String

I will prepare the class to work with a ClassInfo for the Flag type then. If I have time I will create the Flag type aswell

Would setting the return type to a WorldGuardFlag classinfo mean that it will also only accept WorldGuardFlag as changers?

If so, wouldn't this make it "harder" to manage flags?

set flag "greeting" of region %worldguardregion% to %worldguardflag% looks repetitive.

Also, while creating the classinfo, what's the difference between using the normal Flag.class from WorldGuard and creating a WorldGuardClass.class with getters to access its Flag class inside?

I saw that this 2nd way is used for the WorldGuardRegion class for example. Why this double step?

No, region flags accept various types of data (boolean/string/numbers/etc.) so you may need to either accept Object.class or accept all types mentioned here

You will then have to do the proper checking and casting for change method

As for creating a wrapper class for Flag, if that helps a lot I think it's fine, but if it's not really needed then we better stick with WG Flag class

Oh I think my comment here never posted...

the WorldGuardRegion wrapper exists because ProtectedRegion seemingly does not provide any details as to the world it is located in

Gotcha, tysm guys!

I am a little unsure about a flag classinfo, mainly for the fact that it may be rather large + I'm not sure how it might handle WorldGuard addons that add new flags (e.g. defining lang entries)

We don't use final modifier on method pararms anymore

Import ChangeMode directly (not static import)

Suggested change

public Class<?>[] acceptChange(final Changer.ChangeMode mode){

public Class<?>[] acceptChange(ChangeMode mode) {

Almost did all of the required changes (I still have to allow multiple regions in the Priority expression). Also, can I add to the PR the effect for deleting regions? I saw that there isn't one yet.

NotSoDelayed · 2023-05-16T17:07:42Z

The SkriptLang team loves contributions, so feel free to do so!

I would do it in a separate PR if possible. Might be difficult since this PR is based on your main branch. Also, you can just add a changer to ExprRegionNamed

I will PR a change to this after Flag and Priority is done.

return "the worldguard flag " + exprFlag.toString(event, debug) + " of " + getExpr().toString(event, debug) ;

region is not part of the syntax and thus not necessary

You don't need to worry about warnings IMO. You can just silently fail.

+    protected Object[] get(Event event, WorldGuardRegion[] regions) {
+        String flag = exprFlag.getSingle(event);
+        if(flag != null) {


You should prefer to exit if the condition fails. Essentially, this helps prevent code from flying off into space with a bunch of indents. Example:

if (flag == null) return; flag.whatever();

Also, your if statements should have a space between the f and opening parenthesis )

case RESET:

case DELETE:

return CollectionUtils.array();

case SET:

case ADD:

case REMOVE:

case RESET:

you can just combine them :)
