Need some help getting player online list and runnable task in forge

Hi. Anyone know how to accomlish this with the Forge API? I have been searching for a number of days and simply can not find the appropriate information on the web.

 

I wrote a simple bukkit plugin for our servers that writes out player positions into a file every 200 ticks, but I now need to write this for our Forge servers also. This meta data is used by scripts and programs outside of the minecraft server. Pretty Simple piece of code, but I simply haven't found suitable info to convert to Forge. I have the basic forge Mod running based on the example provided with Forge API.

 

BukkitScheduler scheduler = Bukkit.getServer().getScheduler();
scheduler.scheduleSyncRepeatingTask(this, new Runnable() {
            @Override
            public void run() {
       		// open the meta file for writing
       		File mfile = new File(metafile);
       		FileWriter writer;
       		try {
       			writer = new FileWriter(mfile, false);
       			pw = new PrintWriter(writer);
       		} catch(IOException e) {
       			e.printStackTrace();
       		}
            	
            	for(Player i : Bukkit.getServer().getOnlinePlayers()){
            		pw.println(i.getName()+ ":" + i.getLocation().getX() + ":" + i.getLocation().getY() + ":" + i.getLocation().getZ());
            	}
            	
       		pw.close();
        }
}, 0L, 200L);

 

Any information appreciated.

Look for tutorials on tick handler or events.  It is the method you can use for your trigger.  you will have to implement a basic timer for 200 ticks from it.

 

There is an equivalent getserver().getOnlinePlayers, I just don't remember the context off the top of my head. might be "MinecraftServer().getserver.....", you will have to check.  Change Player to EntityPlayer.

 

All your file stuff for writing should be fine.

Thanks a lot both of you. That go me on the right track and I have this working nicely.

 

For those interested (and for any further refinements, gotchas or improvements):

 

I created a new basic ticker class that I registered in the preInit eventhandler routine of the main class:

 

   @EventHandler
    public void preInit (FMLPreInitializationEvent event) {
         .
         .
      FMLCommonHandler.instance().bus().register(new OBTicker("config/"+metafile));

 

and in the ticker class I created a subscribe event onServerTick routine that counts 200 ticks (5 seconds) and runs the command to dump the meta data out:

 

 @SubscribeEvent
 public void onServerTick(TickEvent.ServerTickEvent event) {

	 tickcount++;

	 if (tickcount == 200 ) {
	    task.run(metafile);
	    tickcount = 0;
	 }
 }

 

Pretty straightforward, and thanks again.

    • 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;     }
