# Einführung in Skripte

CraftTweaker uses a custom scripting Language called `ZenScript`, ZenScript is read from `.zs` files that are stored in the `<gamedir>/scripts` folder, if you aren't sure where this folder is, just run `/ct scripts` when in the game and the folder will open.

ZenScript ist eine "top down"-Skriptsprache, was bedeutet, dass ganz oben im Skript die `Imports` stehen müssen, danach werden die `Variablen` deklariert. `Variablen` können zwar auch weiter unten im Skript stehen, allerdings kann man von den übergeordneten Zeilen aus dann auch nicht auf diese `Variable` zugreifen.


Script files have the `.zs` suffix, make sure that it isn't `.zs.txt`!

## What are scripts

Scripts are stored in `<gamedir>/scripts` and are loaded when the player joins a world, much like previous versions of CraftTweaker (excluding 1.12), Scripts CAN be reloaded, just run `/reload`.

When joining a server, the server sends their scripts to the client, and the client runs those scripts. This does mean that a client without any scripts, can join a server and get the changes (useful if you need to disable an item on the server but don't want to force clients to download extra files!)

### Dein allererstes Skript

To get started with Scripts, you can create a very basic file, called `hello.zs` in the `<gamedir>/scripts>` folder; If you aren't sure where the folder is, just run `/ct scripts` and it should open!

In diese Datei packst du die folgende Zeile:

```zenscript
println("Hello world!");
```

Now load up Minecraft and and take a look at the `<gamedir>/logs/crafttweaker.log` file (or run `/ct log` to have the file open in your default text editor).

The `crafttweaker.log` file is located in `<gamedir>/logs` and can be read by any program that can read plaintext files.

It is recommended to use VSCode, Sublime Text or Notepad++ to edit script files, however any program will do.

When choosing a program to use to edit scripts, take a look at what Syntax highlighters are available, most common text editors have ZenScript highlighting support through the use of a plugin.


### Die crafttweaker.log-Datei

Die `crafttweaker.log` verwendet eine bestimmte Syntax, welche ungefähr so aussieht:

```
[HH:MM:SS.ms][TYPE] <message>
```

Im Falle des vorherigen Beispiels, wird dort folgendes stehen:

```
[14:58:06.697][INFO] Hello world!
```

### Kommentare

Mit Kommentaren kannst du deine Skripte besser lesbarer und verständlicher machen!

ZenScript unterstütz drei verschiedene Arten von Kommentaren:

Einzeilig: `// Ich bin ein einzeiliger Kommentar!`

Alternativ einzeilig: `# Ich bin auch ein einzeiliger Kommentar!`

Mehrzeilig:
```
/* Ich bin
ein mehrzeiliger
Kommentar! */
```

Just note, that `#` comments are also used for [PreProcessors](/zencode/Preprocessors/Preprocessors), so while they are still valid comments, they could cause unwanted side effects.
