Source code for BlockLauncher, a launcher that patches Minecraft for Android

BlockLauncher: a custom Minecraft launcher for Android

Building

BlockLauncher's build system is complicated and out of date. It still uses Ant (and thus is incompatible with Android Studio), and uses older versions of various libraries.

Scripts to setup a build environment can be found in tools/ci/ci_build.sh.

This script is tested to work on GitHub Actions' Ubuntu 18.04 image, and on a fresh Ubuntu 19.10 install.

You may need to install:

sudo apt install git p7zip-full openjdk-8-jdk ant
sudo update-java-alternatives -s java-1.8.0-openjdk-amd64

mcpelauncher's Issues

Can't play with mods

Helo!

I have Blocklouncher free and i can't play with mods installed i can only play in safe mod.i have a samsung galaxy tab 2 0.7.0

Ps: i have minecraft pe version 0.7.1

Pls help!!!!!!!!

ModPe scripts can use Blocklauncher's root permissions!

The Rhino js interpreter allows any script to run java code. This means that they can do anything a normal app could do, including using root. And since it's all running as the same app, when you allow blocklauncher root permission you also allow any loaded ModPe scripts to use it as well!

I have tested this on my rooted Note 3, stock Android 4.3, SuperSu 1.8.6, blocklauncher pro 1.6.3, but it should work on any rooted phone that runs blocklauncher.

The following 2 line script writes "Hello World" to /data/test.txt, a location that without su could not be touched:

p = java.lang.Runtime.getRuntime().exec("su");
(new java.io.DataOutputStream(p.getOutputStream())).writeBytes("echo Hello World >> /data/test.txt\nexit");

In just a few lines a malicious script could steal your personal information, impersonate you, or completely wipe out your entire phone!

Crash of the setHealth method

Hmm.

Tracking issue for wishlist methods

Here's a list of methods people wished to see. I'll be removing/adding to this list. Not everything on here is going to be added.
From Reddit:

Some quick would-be-useful ideas:

    more level options via script (see bottom).
    a compiled script system in addition to interpreted scripts
    a built in random seed gen to make up for JavaScript's lack thereof
    spawning of particles via script.

possible functions for Levels:

    Level.create(Name,Seed,Mode,Directory)
    Level.getName()
    Level.getSeed() //isn't this one already existant?
    Level.getMode()
    Level.getDir()
    Level.setMode()
    Mcpe.loadLevel(Name,Dir)
    Mcpe.closeLevel()
    Mcpe.delLevel(Name,Dir)
    Level.setSpawn(x,y,z)
    Level.setTime(time)
    Level.addTime(time)

From the thread:

ModPE.setWeaponItem(image, image,damage,durability,Id)
ModPE.setArmorItem(image,image,durability,protection,id)
ModPE.setBowItem(image,image,durability,damage,I'd)
ModPE.setBlockItem(image,image,blockitplaces,id) This is kinda like how the door works. Its an item but when placed it spawns a door.

[Building] Building MCPELauncher?

I'm currently trying to build MCPELauncher, as @MCMrARM has instructed me. During compiling, errors occur. I'm currently building using API18 or android-18.

Any help?

crashes too much

@zhuowei i play on a Samsung Galaxy Exhibit and when i tap a world to play it loads up all the way to when it is saving chunks and it stop and crashes and exits the app on its own. Please fix this bug. Please please please.

Level.setSpawn has some wrong

If you've ever slept in the evening, it will not work

newLevel hook crashes game

As reported at http://www.minecraftforum.net/topic/1675581-blocklauncher-an-android-app-that-patches-minecraft-pe-without-reinstall/page__st__2520#entry30089884

Android stability

BL often crashes on KitKat and other Android versions: always on exit, it also drops many EGL errors to LogCat. Maybe, native part of Android was really changed? Have a look at new OpenGL's implementation.
Vanilla MC doesn't crash.
MC: 0.8.1
BL: 1.6.3

Allow 3rd Party Apps to Import ModPEScripts & Scripts

Hey
Can someone please add Support for 3rd Party apps to import ModPEScripts by providing a URL/File Path and the same for Texture Packs (File Path) and Skins (File Path)

If this is already possible, I would appreciate an example

Thanks

Crash when defineBlock called before source blocks initialized

Block.defineBlock crashes if the material source block is not initialized.

Thanks to Donalddoesmc for the report.

Level.setTile

Hmm.
setTile(x, y, z, id, damage);
Level.setTile(x, y, z, id);
No damage value for Level.setTile?
If we are trying to get people to move to Object-Orientated callbacks, shouldn't the corresponding callback be the same as the original one?

Many thanks,
Connor4898

Commands Bug

When I was using my LG (for specificating, LG Optimus L7 P-708g), I just was testing my command mod. When I pressed enter, BlockLauncher Pro just crashed and I got out of the app.

Too many crashes

@zhuowei my game crashes too much. The device i have is a Samsung Galaxy Exhibit 4G T-mobile. Please fix this please please please.

Random stuff that I need to fix

1. Merge translations: es
2. transparent Hovercar
3. Realms support

Byteandahalf's nitpicks

• errors in modTick opens infinite number of error dialogs - perhaps just stop the script after a certain number of errors, or stop displaying errors?
• typing in commands still posts the command to chat

game still randomly crashes

I'm using a nexus 7

Can't input characters

Many people reported that they can't input into chat or signs.

Reported on:

• Samsung Galaxy Note 2, 4.1.2 Jellybean, and SwiftKey.
• Galaxy S-Plus GT-I9001, Android GingerBread 2.3.6, Samsung Keyboard
• Phone: Sony Xperia Arc S Android Version: 4.0.4 Keyboard: Sony Keyboard
• Amazon Kindle Fire HD, Custom ICS variant, Amazon Keyboard, actually blackscreens the tablet (?!)

You got an issue? Please write down the information according to this template:
Device:
Android version:
BlockLauncher version:
Keyboard:
Input mode (tapping, swiping, voice typing, hardware keyboard)
Does it happen in the official Minecraft PE?

android 4.1.2 jellybean

Hi, thanks for replying my previous questions. But can you update block launcher pro such that it supports Samsung jellybean 4.1.2 android thank you and have a nice day

Make patch browse start at PT patches dir

It crashes, after building it myself

I have tried to build the newest version, but it crashes when installed on phone. Logcat:
https://gist.github.com/MCMrARM/a16e399816e96a484556
It looks like you didn't include tinysubstrate.

ItemCategory?

On line 178, I see this code:

ScriptableObject.putProperty(scope, "ItemCategory", classConstantsToJSObject(ItemCategory.class));

However, javac complains that it cannot find an ItemCategory definition.
And sure enough, when I search for it, I see this:

Is this intentional?
I cannot build MCPELauncher with this error.

EDIT: There seems to be methods for it, but no class definition.

Texturepacks API broken

My Public API update commit AndroidManifest.xml and yours AndroidManifest.xml. Have deeper look at texturepacks support. Have you already found the difference? Wtf?

When I open the app it wants me to choose continue or return to normal. When I press return to normal it will quit to main page then open with the screen black
Google play store wants me to sent to you my device model and my operating system version.
Android 4.1.2, jellybeans, GT-19305

Level.setTime works wrong

The time isn't the real time; it's just something strange; I'll look into this, later.

BlockLauncher crashes when locking device

When you are using BL (even without mods on), and then lock your screen, when you unlock it, BL will crash and close. I can get a LogCat (CatLog) file if requested.

when is the update for 0.8.0 minecraft pocket edition coming?

I have downloaded 0.8.0 build 6 minecraft pocket edition and block launcher do not support 0.8.0

new stuff

I was hoping maybe you could make it so I could use plugins (that are for pocketmine) in mcpe without a server. Something where I can install the plugins in blocklauncher pro instead of using a server. I hope that makes sense

About change the skin in the game!

long before, BlockLauncher can apply the skin in the game right now.
but now, we can't apply skin and change in the game right now.
can you fix it?

Bugged Custom Items (Lastest BL Beta, 1.6.8 beta 4)

When you add custom items (ModPE.setItem, ModPE.setFoodItem), BL displays the item's icon, but not the name. It always displays the name as "undefined", and when you use ModPE.setFoodItem, you can eat it, but it also displays the name as "undefined" and doesn't raises any hearts. I also added custom blocks and custom craft recipes (Crafting and Furnace) and BL crashed when I opened the crafting table. If requested, I can get a CatLog file of the crash.

crashes too much

@zhuowei i have an Android. Its a Samsung Galaxy Exhibit. its version is 2.3.6 . Block launcher pro is a great app but it crashes and exits the app each time i tap on a world to play. Please fix this bug.

Mods will crash & not work & BlockLauncher Pro & BlockLauncher free will ask me to go to Safe Mode or Normal Mode which in Normal Mode the mods glitch/bugs out

Please help me, Mr Zhuowei.

fails on Samsung Note 3 and perhaps other Knox-fortified devices

http://www.minecraftforum.net/topic/1675581-blocklauncher-an-android-app-that-patches-minecraft-pe-without-reinstall/page__st__1080#entry24779789

It seems SELinux does not like executable-and-writable pages.

Temp workaround is to bring BlockLauncher into semi-safe mode: only load .mods after restart, disable anything that needs live patching (ModPE Scripts, live patched .mods)

French

I translate block launcher in French I could give by dropbox once finished?

ModPE.setFoodItem crash

When I will give user food made with ModPE.setFoodItem, game will crash when they will get it in hand.
