How does it work?
Minecraft client can resolve translations components (e.g. iris.shaders.reloaded, item.minecraft.diamond, etc.).
Plugin utilizes it - opens and closes sign menu when player joining.
API
Force probe player
public void myProbe(Player player) {
NMinimapIrisBlocker.getInstance().probe(player, ProbeCause.CUSTOM)
.thenAccept(result -> {
System.out.println("CHECK RESULT: " + result.result());
System.out.println("RESOLVED TRANSLATIONS");
System.out.println(result.resolved());
});
}
Handle on-join check (to open menu for example)
@EventHandler
public void handleJoinCheck(AsyncPlayerCheckDoneEvent e) {
if (!e.getCause().equals(ProbeCause.JOIN))
return;
var player = e.getPlayer();
System.out.println("CHECK RESULT: " + e.getResult().result());
System.out.println("RESOLVED TRANSLATIONS");
System.out.println(e.getResult().resolved());
player.openInventory(yourInventory);//etc
}
