My code:
Main class:
package arkadarktime;
import org.bukkit.plugin.java.JavaPlugin;
import su.plo.voice.api.addon.InjectPlasmoVoice;
import su.plo.voice.api.server.PlasmoVoiceServer;
public final class PlasmoVoiceRadioAddon extends JavaPlugin {
private final RadioAddon addon = new RadioAddon(this);
@InjectPlasmoVoice
private PlasmoVoiceServer voiceServer;
@Override
public void onLoad() {
PlasmoVoiceServer.getAddonsLoader().load(addon);
}
}Addon class:
package arkadarktime;
import su.plo.voice.api.addon.AddonInitializer;
import su.plo.voice.api.addon.InjectPlasmoVoice;
import su.plo.voice.api.addon.annotation.Addon;
import su.plo.voice.api.event.EventPriority;
import su.plo.voice.api.event.EventSubscribe;
import su.plo.voice.api.server.PlasmoVoiceServer;
import su.plo.voice.api.server.audio.capture.ServerActivation;
import su.plo.voice.api.server.event.connection.UdpClientConnectEvent;
@Addon(id = "pv-addon-radio", name = "Radio Addon", version = "1.0", authors = {"ArkaDarkTime"})
public class RadioAddon implements AddonInitializer {
private final PlasmoVoiceRadioAddon plugin;
@InjectPlasmoVoice
private PlasmoVoiceServer voiceServer;
ServerActivation activation = voiceServer.getActivationManager().getActivationByName("proximity").orElseThrow(() -> new IllegalStateException("Proximity activation not found"));
public RadioAddon(PlasmoVoiceRadioAddon plugin) {
this.plugin = plugin;
}
@Override
public void onAddonInitialize() {
plugin.getLogger().info("RadioAddon initialized");
voiceServer.getEventBus().register(this, UdpClientConnectEvent.class, EventPriority.NORMAL, this::onClientConnected);
}
@Override
public void onAddonShutdown() {
plugin.getLogger().info("RadioAddon shut down");
}
@EventSubscribe
public void onClientConnected(UdpClientConnectEvent event) {
plugin.getLogger().info("CLIENT CONNECTED!");
activation.onPlayerActivationStart(player -> System.out.println(player + " start speaking to activation"));
activation.onPlayerActivation((player, packet) -> {
System.out.println(player + " is speaking to activation");
return ServerActivation.Result.HANDLED;
});
activation.onPlayerActivationEnd((player, packet) -> {
System.out.println(player + " has finished speaking to activation");
return ServerActivation.Result.HANDLED;
});
plugin.getLogger().info(event.getConnection().getPlayer() + " connected to UDP");
}
}I know that pv-addon-discs has radio support, I am creating this for myself to learn how to work with your api
You can't access voiceServer during class initialization, it's only available after the addon initialization (in onAddonInitialize).
So in your case you should access activation manager in the onAddonInitialize:
@Override
public void onAddonInitialize() {
ServerActivation activation = voiceServer.getActivationManager().getActivationByName("proximity").orElseThrow(() -> new IllegalStateException("Proximity activation not found"));
}
