In this guide, i will show you how to setup a whitelist on a Minecraft server. A whitelist, is a list of Minecraft usernames that is allowed to access your server. Any user that is not on this list, can’t login even if they have the IP to join the server.

Using a whitelist is always recommended when setting up a private server, where you only want your friends, and the poeple you want to join, to also be able to join. And not get any griefers or anyone you don’t know to access the server.

You can use these commands in the console of the server. But i will do it ingame.

First, make sure you are “opped” on the server, if you login. If you do this in the console on the server then you don’t need to op you first.

Login to your server.

Now do the following:

First i recommend adding the players you want on. For that your need their Minecraft usernames.

1:

Use the command:

/whitelist add <username>

In the example i do /whitelist add kehaan

Now keep adding the players you want to be able to access the server.

In MineCraft 1.11, a new “locate” command was added. This command shows the coordinates of the closest EndCity, Fortress, Mansion, Mineshaft, Monument, Stronghold, Temple and village or other special buildings/structures in newer versions of Minecraft.

All you have to do is use the following command:

/locate (AND Then use TAB)

You can then use “tab” and it shows the different arguments you can use. Or you can just write the argument. Like

/locate EndCity

Which will show the nearest EndCity

In newer versions there is also a Buried_Treasure, EndCity, Fortress, Mansion, Mineshaft, Monument, Ocean_Ruin, Shipwreck, Stronghold, Desert_Pyramid, Igloo, Jungle_Pyramid, Swamp_Hut, Village and Pillager_Out

So best advice would be to write /locate TAB, and then use the tab button, to see which kind of arguments you can use in the version of Minecraft that you plays.

Want to disable the daylight cycle, so the time will stay the same? Then do the following command:

/gamerule doDaylightCycle false

If you want to make the time move again, change false to true 🙂

So if you want the time to be at x time. First use the time set command, to set the time. And then do above gamerule.

Want to clear ingame chat quickly? Then if you play MC 1.9 and above, you can use the ingame keybind:

f3 plus d

(Do not press +/plus, just f3 and d on the same time.)

If under 1.9, you could for 1.7.10 use something like https://www.curseforge.com/minecraft/mc-mods/clearchat which does the same thing just by pressing delete button.

Do you get a error when launching a modpack from the Twitch Minecraft App? That says something like:

” Failed to download file, the file contents differ from what was expected.
Name: jopt-simple-4.6.jar
URL: https://libraries.minecraft.net/net/sf/jopt-simple/jopt-simple/4.6/jopt-simple-4.6.jar
Filename on disk: jopt-simple-4.6.jar
Path: C:\Users\xxxxxxxxxxxxxxxxxxxx
Exists: File “

The issue have been reported to Curse/Twitch, but until they are fixing it. You can fix it yourself. Do the following:

1: Go to the link in the “URL” part. This should download the missing file.

2: Go to the file which is shown in the “path” part. Yours will be different then the one in the screenshot.

3: Now replace/place the file you downloaded at above location.

4: Start the modpack you want to play. It should now start normally.

Having trouble when using Twitch Launcher, that it does not save the window/scree resolution you have set? Then do the following:

• Click on the windows button, and write %appdata% and open the appdata folder. This is where minecraft and twitch folder is usually found.

• Now find Twitch folder

• Now open the “MinecraftSettings.json” file.
  I like to play in 1920*1080, so i have changed it to the following:

“resolutionWidth”: 1920,
“resolutionHeight”: 1080
}

• Hit, save. And restart the launcher. Now your game should start in 1920*1080 every time it loads the pack you play. (I also changed it in the Minecraft.settings, file. But doing it in json file only should be enough.

If it does not, you may need in the Twitch launcher to just once, change the resolution to what you want here too. BUUUT usually above solves the issue 🙂

There is 20 ticks per second.

That means that 1 tick happens every 0.05 seconds.

Above info is used a lot when making recipes with CraftTweaker. As many machines needs to know how many ticks a machine should run for with x amount of power. Like for some GregTech machines you need to use:
.duration(40) .EUt(120)
Which then means that the machine will run for 40 ticks which is 2 seconds, and every tick it will use 120 EU, which is a total of 4800 EU.

Want to check item/block IDs without having to use a mod or a command, for every item/block while holding it in its hands?

Then press (On the same time):

F3 (and) H

And you can as you see on the screenshot, see item/block ids by hovering your mouse over them.

If you want to clear / remove a lot of item drops in a world, you can use the following command:

/kill @e[type=item]

This command will clear/remove all the items that is laying in the world.
