Make a player invisible? Access render classes?

Hey guys,

 

Short question, Looking for a hook for the server side so I can set a player to invisible somehow?

 

Have searched the forums and been looking through the player classes but Im missing something.

 

Im trying to set a player to invisible from the server side so he disappears on all clients? Should be possible to do without editing client files?

I know there is a bukkit plugin called "vanish". I think the way it works is that it stops the server from sending the packets about vanished or invisible players to the rest of the players.

I haven't looked at any of this before but it is an interesting topic. I suggest trying to look into achieving the above. I might have a poke around too and reply if i find anything of interest on the subject.

 

EDIT:

I found the EntityTracker and EntityTrackerEntry classes to be something of interest. Entity tracker takes a parameter of WorldServer so I'm guessing you would get your World Server by casting WorldServer to the worldObj field of EntityPlayerMP. You could then get an instance of the world's EntityTracker and finally get an EntityTrackerEntity that corresponds to the player you want and use the removePlayerFromTracker  and removePlayerFromWatchingList methods to stop packets being sent. You will need to do this on an "onTick" basis to all "invisible" players.

If I helped you, thank me. If I didn't, let me know.

Thanks dude,

 

Have this so far if anyone else interested aswell:

 

EntityPlayerMP playerMP = MinecraftServer.getServer().getConfigurationManager().getPlayerForUsername(var1.getCommandSenderName());

WorldServer[] worldservers = MinecraftServer.getServer().worldServers;

worldservers[1].getEntityTracker().removeEntityFromAllTrackingPlayers(playerMP);

 

 

Just testing with worldserver1 for now, Is there anyway to actively debug while the server/client is running?

 

The code above removes the player allright but it also makes everyone else invisible to that player. Looking into updating with onTick now (I think thats why everyone else disapears).

Is the code you are using to set players invisible running on the server-side proxy?

 

Also, in eclipse, you can run a program in debug mode just like running it normally. Next to the green run button there should be the same type of button with a picture of a bug. It works the same in that you can select which program to run in debug (client/server).

 

Debugging is extremely powerful in eclipse and because it is such a large topic there a great amount of resources out there. I probably can't explain how to use it all very well so I'll link you to this in-depth article: http://www.vogella.com/articles/EclipseDebugging/article.html

It is very detailed but you can just skim over it to get the basic concepts.

 

Finally, just a last note on debugging with the client and server running at the same time. When debugging and your server hits a breakpoint or you manually stop it, the program is paused. If a client is connected it will time out after a few seconds which can make debugging server-side stuff annoying. But rest-assured it is still usable for most things.

If I helped you, thank me. If I didn't, let me know.

I wrote something like this, I believe it requires an access transformer. I got as far as the 'vanish' part, not the 'unvanish' part. But, here's the code: https://github.com/keepcalm/ForgeCommands/blob/master/src/keepcalm/mods/forgecommands/api/VanishManager.java.

 

The other problem I had was that when a player walked near the vanished player, the vanished player would flicker in and out of visibility. Perhaps see how the invisibility potion was done, and work out how to remove the particles?

 

Protip: try and find answers yourself before asking on the forum.

It's pretty likely that there is an answer.

Tired of waiting for mods to port to bukkit?

use BukkitForge! (now with a working version of WorldEdit!)

Thanks keepcalm thats going in the right direction, I have one problem tho:

 

EntityTrackerEntry ete = (EntityTrackerEntry) et.trackedEntityIDs.lookup(player.entityId);

 

the "trackedEntityIds" is a private variable on entitytrackerentry so I have no access to it and I dont want to edit any src files, Any idea of how else I could get a handle on it?

Use an coremod + AT. http://www.minecraftforge.net/wiki/Using_Access_Transformers - it's a bit outdated, but hopefully you can get the general gist of things ;)

    • They were already updated, and just to double check I even did a cleanup and fresh update from that same page. I'm quite sure drivers are not the problem here. 
    • i tried downloading the drivers but it says no AMD graphics hardware has been detected    
    • Update your AMD/ATI drivers - get the drivers from their website - do not update via system  
    • As the title says i keep on crashing on forge 1.20.1 even without any mods downloaded, i have the latest drivers (nvidia) and vanilla minecraft works perfectly fine for me logs: https://pastebin.com/5UR01yG9
    • Hello everyone, I'm making this post to seek help for my modded block, It's a special block called FrozenBlock supposed to take the place of an old block, then after a set amount of ticks, it's supposed to revert its Block State, Entity, data... to the old block like this :  The problem I have is that the system breaks when handling multi blocks (I tried some fix but none of them worked) :  The bug I have identified is that the function "setOldBlockFields" in the item's "setFrozenBlock" function gets called once for the 1st block of multiblock getting frozen (as it should), but gets called a second time BEFORE creating the first FrozenBlock with the data of the 1st block, hence giving the same data to the two FrozenBlock :   Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=head] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@73681674 BlockEntityData : id:"minecraft:bed",x:3,y:-60,z:-6} Old Block Fields set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=3, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} Frozen Block Entity set BlockState : Block{minecraft:black_bed}[facing=east,occupied=false,part=foot] BlockPos{x=2, y=-60, z=-6} BlockEntity : net.minecraft.world.level.block.entity.BedBlockEntity@6d1aa3da BlockEntityData : {id:"minecraft:bed",x:2,y:-60,z:-6} here is the code inside my custom "freeze" item :    @Override     public @NotNull InteractionResult useOn(@NotNull UseOnContext pContext) {         if (!pContext.getLevel().isClientSide() && pContext.getHand() == InteractionHand.MAIN_HAND) {             BlockPos blockPos = pContext.getClickedPos();             BlockPos secondBlockPos = getMultiblockPos(blockPos, pContext.getLevel().getBlockState(blockPos));             if (secondBlockPos != null) {                 createFrozenBlock(pContext, secondBlockPos);             }             createFrozenBlock(pContext, blockPos);             return InteractionResult.SUCCESS;         }         return super.useOn(pContext);     }     public static void createFrozenBlock(UseOnContext pContext, BlockPos blockPos) {         BlockState oldState = pContext.getLevel().getBlockState(blockPos);         BlockEntity oldBlockEntity = oldState.hasBlockEntity() ? pContext.getLevel().getBlockEntity(blockPos) : null;         CompoundTag oldBlockEntityData = oldState.hasBlockEntity() ? oldBlockEntity.serializeNBT() : null;         if (oldBlockEntity != null) {             pContext.getLevel().removeBlockEntity(blockPos);         }         BlockState FrozenBlock = setFrozenBlock(oldState, oldBlockEntity, oldBlockEntityData);         pContext.getLevel().setBlockAndUpdate(blockPos, FrozenBlock);     }     public static BlockState setFrozenBlock(BlockState blockState, @Nullable BlockEntity blockEntity, @Nullable CompoundTag blockEntityData) {         BlockState FrozenBlock = BlockRegister.FROZEN_BLOCK.get().defaultBlockState();         ((FrozenBlock) FrozenBlock.getBlock()).setOldBlockFields(blockState, blockEntity, blockEntityData);         return FrozenBlock;     }
