Ah I never thought about that, great idea. Thanks for the suggestion dude.

@SubscribeEvent public void onAttachCapabilities(AttachCapabilitiesEvent<Entity> event) { if (event.getObject() instanceof PlayerEntity) { PlayerEntity playerEntity = (PlayerEntity) event.getObject(); playerEntityPortalManagerMap.put(playerEntity, new PortalManager(playerEntity.getEntityWorld(), playerEntity)); } } public PortalManager(World worldIn, Entity playerIn) { this.portalCommands = new PortalCommands( worldIn.getServer().getCommandSource() .withPermissionLevel(2) .withEntity(playerIn) .withFeedbackDisabled(), worldIn.getServer().getCommandManager()); PORTAL_1_ID = "portal_1_" + playerIn.getUniqueID(); PORTAL_2_ID = "portal_2_" + playerIn.getUniqueID(); } Here's the exception: net.minecraft.crash.ReportedException: Ticking memory connection at net.minecraft.network.NetworkSystem.tick(NetworkSystem.java:154) ~[?:?] {re:classloading} at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:899) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:821) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:84) ~[?:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.server.MinecraftServer.func_240802_v_(MinecraftServer.java:664) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.lambda$func_240784_a_$0(MinecraftServer.java:233) ~[?:?] {re:classloading,pl:accesstransformer:B} at java.lang.Thread.run(Thread.java:748) [?:1.8.0_181] {} Caused by: java.lang.NullPointerException at net.minecraft.entity.player.PlayerEntity.getName(PlayerEntity.java:1793) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.command.CommandSource.withEntity(CommandSource.java:75) ~[forge-1.16.5-36.1.0_mapped_snapshot_20200514-1.16-recomp.jar:?] {re:classloading} at com.namarino41.portalgunforge.util.PortalManager.<init>(PortalManager.java:39) ~[main/:?] {re:classloading} at com.namarino41.portalgunforge.items.PortalGunItem.onAttachCapabilities(PortalGunItem.java:108) ~[main/:?] {re:classloading} at net.minecraftforge.eventbus.ASMEventHandler_3_PortalGunItem_onAttachCapabilities_AttachCapabilitiesEvent.invoke(.dynamic) ~[?:?] {} at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:85) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:302) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:283) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.event.ForgeEventFactory.gatherCapabilities(ForgeEventFactory.java:579) ~[?:?] {re:classloading} at net.minecraftforge.event.ForgeEventFactory.gatherCapabilities(ForgeEventFactory.java:573) ~[?:?] {re:classloading} at net.minecraftforge.common.capabilities.CapabilityProvider.gatherCapabilities(CapabilityProvider.java:48) ~[?:?] {re:classloading} at net.minecraftforge.common.capabilities.CapabilityProvider.gatherCapabilities(CapabilityProvider.java:44) ~[?:?] {re:classloading} at net.minecraft.entity.Entity.<init>(Entity.java:221) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.entity.LivingEntity.<init>(LivingEntity.java:207) ~[?:?] {re:classloading} at net.minecraft.entity.player.PlayerEntity.<init>(PlayerEntity.java:160) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.entity.player.ServerPlayerEntity.<init>(ServerPlayerEntity.java:182) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.management.PlayerList.createPlayerForUser(PlayerList.java:419) ~[?:?] {re:classloading} at net.minecraft.network.login.ServerLoginNetHandler.tryAcceptPlayer(ServerLoginNetHandler.java:122) ~[?:?] {re:classloading} at net.minecraft.network.login.ServerLoginNetHandler.tick(ServerLoginNetHandler.java:66) ~[?:?] {re:classloading} at net.minecraft.network.NetworkManager.tick(NetworkManager.java:244) ~[?:?] {re:classloading} at net.minecraft.network.NetworkSystem.tick(NetworkSystem.java:151) ~[?:?] {re:classloading} ... 6 more withEntity calls toString which is causing the error. Again, is there a way I can get the fully initialized player?

Clearly...how can I do it then?

I was trying to initialize another object using the player. https://github.com/namarino41/portalgun_forge/blob/ef13a032415f9a0a484005c847eae5b8ae5a7782/src/main/java/com/namarino41/portalgunforge/util/PortalManager.java#L35

Interesting, I wasn't trying to print out the player. So is there another way to get the fully initialized player?

Yeah but doing that results in that exception I noted above.

Well basically I need to create an object using the player and the world.

Hmm, I'm trying to get the player though. Anyway I can do that?

Hello. I'm playing around with the AttachCapabilitiesEvent<Entity>. I'm trying to attach something to the player, but right now I'm just seeing if I can get the player object. I'm getting a NullPointerException though when I try to do this. Here is the relevant code: public class PortalGun extends Item{ public PortalGun() { super(new Item.Properties().group(ItemGroup.TOOLS)); MinecraftForge.EVENT_BUS.register(this); } @SubscribeEvent public void onAttachCapabilities(AttachCapabilitiesEvent<Entity> event) { if (event.getObject() instanceof PlayerEntity) { // do something with Player } } } When the player loads into the game, I get the following error: [02:05:50] [Server thread/ERROR] [minecraft/MinecraftServer]: Encountered an unexpected exception net.minecraft.crash.ReportedException: Ticking memory connection at net.minecraft.network.NetworkSystem.tick(NetworkSystem.java:154) ~[?:?] {re:classloading} at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:899) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:821) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:84) ~[?:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.server.MinecraftServer.func_240802_v_(MinecraftServer.java:664) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.lambda$func_240784_a_$0(MinecraftServer.java:233) ~[?:?] {re:classloading,pl:accesstransformer:B} at java.lang.Thread.run(Thread.java:748) [?:1.8.0_181] {} Caused by: java.lang.NullPointerException at net.minecraft.entity.player.PlayerEntity.getName(PlayerEntity.java:1793) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.entity.Entity.toString(Entity.java:2362) ~[?:?] {re:classloading,pl:accesstransformer:B} at java.lang.String.valueOf(String.java:2994) ~[?:1.8.0_181] {} at net.minecraftforge.fml.loading.TracingPrintStream.println(TracingPrintStream.java:65) ~[forge-1.16.5-36.1.0_mapped_snapshot_20200514-1.16-launcher.jar:36.1] {} at com.namarino41.portalgunforge.items.PortalGunItem.onAttachCapabilities(PortalGunItem.java:106) ~[main/:?] {re:classloading} at net.minecraftforge.eventbus.ASMEventHandler_2_PortalGunItem_onAttachCapabilities_AttachCapabilitiesEvent.invoke(.dynamic) ~[?:?] {} at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:85) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:302) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:283) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.event.ForgeEventFactory.gatherCapabilities(ForgeEventFactory.java:579) ~[?:?] {re:classloading} at net.minecraftforge.event.ForgeEventFactory.gatherCapabilities(ForgeEventFactory.java:573) ~[?:?] {re:classloading} at net.minecraftforge.common.capabilities.CapabilityProvider.gatherCapabilities(CapabilityProvider.java:48) ~[?:?] {re:classloading} at net.minecraftforge.common.capabilities.CapabilityProvider.gatherCapabilities(CapabilityProvider.java:44) ~[?:?] {re:classloading} at net.minecraft.entity.Entity.<init>(Entity.java:221) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.entity.LivingEntity.<init>(LivingEntity.java:207) ~[?:?] {re:classloading} at net.minecraft.entity.player.PlayerEntity.<init>(PlayerEntity.java:160) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.entity.player.ServerPlayerEntity.<init>(ServerPlayerEntity.java:182) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.management.PlayerList.createPlayerForUser(PlayerList.java:419) ~[?:?] {re:classloading} at net.minecraft.network.login.ServerLoginNetHandler.tryAcceptPlayer(ServerLoginNetHandler.java:122) ~[?:?] {re:classloading} at net.minecraft.network.login.ServerLoginNetHandler.tick(ServerLoginNetHandler.java:66) ~[?:?] {re:classloading} at net.minecraft.network.NetworkManager.tick(NetworkManager.java:244) ~[?:?] {re:classloading} at net.minecraft.network.NetworkSystem.tick(NetworkSystem.java:151) ~[?:?] {re:classloading} ... 6 more How can I work around this and get the player? Thanks.

How do I get the player though? Can you please give me an example of how to do this?

I'll ask the question again. Differently this time. I would like to initialize the PM outside of the item method. It requires a CommandSource, a Commands object, and the player. Right now, these are gotten from the player in the item method. How can I accomplish this without using the item method?

That was before you said you had no idea what I was talking about...so clearly you still didn't understand and yet you didn't ask for more clarification so you could actually help.

Then I told you and you said you have no idea what my issue was

If you don't know what the issue is, why not ask for clarification?

The Portal Manager takes in a CommandSource and a Commands object. How do I get these without the Item method? I can't use world and player from the item method because then the player would first have to use the item before the portal manager knows anything about the world. I think it's made pretty clear in my question.
