JavaScript is programming language.

Programmers use programming language because it is easier to write

ModPE.showTipMessage("Hi!");

than

something out of 0 and 1 (a computer saves informations in 0 and 1 or in other words in on or off, and this in transistors)

but you only need to know how to use this programming language.

Learning to make ModPE Scripts is for beginners really easy, because you can instant test them with BlockLauncher to find errors and you don´t have to compile them (compiling makes out of a project of a program or Apk or whatever by creating an .exe or .apk-file (or other files, based on system and programming language) out of the project).

---

JavaScript is based on Java and is a programming language for Websites. And for ModPE-Scripts.

You create a Mod by using the functions (as shown in the Video luna09876 postet) and save this in a .js-file and import it with BlockLauncher. Ready!

---

How to find these functions:

Open BlockLauncher, go to settings-->nerdy stuff-->dump ModPE functions

Or look on this list of functions, it´s not complete but it helps you to understand them better:

---

But a ModPE-Script just out of those functions wouldn´t be good, because you can create items and blocks etc but you can´t interact with things in the game, like if the player attacks a mob.

For this you need hooks.

Here´s a list of all hooks: https://github.com/Connor4898/ModPE-Docs/wiki/Hooks

Hooks are functions that are activated (called called (BlockLauncher calls this Hooks if something in the game happens)) if somthing happens.

---

Here´s an example for a hook used together with a function:

function attackHook(attacker, victim){

Player.addItemInventory(276,1,0);

}

If you would paste this in a .js-file and use it with BlockLauncher you would become a diamond sword whenever you attack a mob.

Lines in Mods that starts with

//

are comments and does nothing in the Mod. I write some comments, so you can understand better what I mean.

But what if you want this happen only if you attacked a specific mob, for example a spider?:

function attackHook(attacker, victim){

if(Entity.getEntityTypeId(victim)==35){ //if does somthing that is in the { } after the if()-condition if the things in the if are true, so if victim has the Entity-Id 35 (that´s the Id of the spider) the Mod calls the function Player.addItemInventory and gives the Player a diamond sword, for other mobs it does nothing because there´s nothing more after the if

Player.addItemInventory(276,1,0);

}

}

And if you want to give the Player a diamond sword if the Entity is a spider and do something other if not?:

function attackHook(attacker, victim){

if(Entity.getEntityTypeId(victim)==35){

Player.addItemInventory(276,1,0);

}else{

clientMessage("Not a spider!");

}

}

This is the normal if-else:

if(condition){

//do something

}else{

//do something other

}

The { } shows the Mod what is in the if and else, so you can

if(condition){

//do something

//do something

/...

}else{

//do something other

//...

}

make more lines with more functions.

This are just really basic things, and if you want to understand JavaScript better you should do what MattdaveMatt said.

You don´t need ModCraft to make Mods, you just need a text-editor (like DroidEdit). But ModCraft can be a help.

Could i have some help too im planning an amazing Dragonball Z mod

Saying "help" is good - better would be to tell with what, what the problem is.

You don´t need to do it like that anymore:
