Good, but you missed a few hooks.

function deathHook(murderer, victim) //when a mob dies
function entityAddedHook(entity) //when an entity enters the world. E.g. Arrow, snowball, etc.
function entityRemovedHook(entity) //when an entity is removed from the game. E.g. Arrow, snowball, etc.

There might be more but not that I know of

THANKS! I needed that.

Amazing! Just what I needed!

No problem. I could also help with the tutorial, and you should make a website for it.
Maybe even a Github

print 'test worked!'
}
}

or...???

Thanks!

function procCmd(cmd)

var Data = cmd.split(" ");

I do have a website! Not too developed though : here

By the way, could you help explaining how to use those functions you told me? I don't know how yet. xD

Javascript (ModScript) tutorial
A must-read for noobs to modding
If you know modding please help me find the mistakes.
Post not finished.
I am not making an independent thread for this because there should be as little duplication as possible for things like this.
Normally, I would advise people to read w3schools, but it is in fact for html. So I decided to include syntax of javascript.

First, let's go into the basic script syntax:
A script is made up of functions. A function is something the reader (i.e. BlockLauncher) would operate its contents.
Basically you can delete all line breaks (i.e. what is inserted when you press 'enter'. A few exceptions are explained below.
The format of a function:

function functionName(parameterOne, parameterTwo){
//contents of the function
/*comment*/
}

The code in each line after the symbol // will be ignored until there is a next line. The ones surrounded by /* and */ are also ignored. These are called comments.

The function name can be anything, but to let BlockLauncher run it, you must use a particular name.
These functions are called hook functions, whose contents are modder-defined.
What are functions that are not hooks? I will explain later.
These are a list of hook function names, as of BlockLauncher version 1.5.2:

function useItem(x,y,z,item,block,side){
}
function destroyBlock(x,y,z,side){
}
function attackHook(attacker,victim){
}
function procCmd(cmd){
}
function deathHook(murderer,victim){
}
function newLevel(){
//BlockLauncher calls this when a world is loaded.
}
function leaveGame(){
//Self-explaining
}
function modTick(){
// called every 1/20 seconds.
}

This three functions have no parameters. What are parameters?
For example, when the player taps a bedrock block (bedrock's id: 7) holding an iron sword (iron sword's id: 267), how can you be informed what is the coordinates and type of the block, and which side of it is tapped, and that the player is holding an iron sword?
The answer is parameters. Parameters are a kind of local variables.
What are variables?
A variable is a value, that can be an integer, a decimal number, a piece of text (in computer language called a string), a player, a mob, an entity... basically everything can be saved through a variable. A variable can be accessed through a variable name, acceptable characters are CAPITAL or lowercase letters, numbers 1-10 and _ (only acceptable at the middle). They are called just like algebra, except that you cannot do 3a but a*3.
Variables can be classified into local and global. A local variable is deleted when the function has ended, and a global variable is deleted when the script is unloaded (i.e. leave game).
To define a non-parameter local variable, the code is:

var varName = /*value*/;

The value can be the following:
85365.3477 (any numbers)
A function with a
'Shbdjkfu48$*(-&9)-oy'
"%+%Yfhiugkue"
' and " have no difference, bu

Actually, the set-up of a command is very complicated. Here's what it should be :

function procCmd(cmd)
{
var Data = cmd.split(" ");
if(Data[0]=="test")
{
print("Test worked!");
}
}
