This project aims to create a custom Minecraft experience based on Minecraft: Pocket Edition as of 2011. It's based on the mcpe01_canada.apk build of the game.
Its goals are:
**Its goals are:**
* To add Quality-of-Life features to Minecraft: Pocket Edition, such as a brighter color gamut, an in-game options menu, etc.
* To add features that were in Minecraft Alpha and the early Betas in 2011. (before and during Minecraft PE's development - this excludes hunger, for example, as it was added in Beta 1.8)
* To keep the source code layout similar to the original Minecraft PE (reconstructed from clues hidden within certain versions of the game, such as the 0.1.0 touch prototype/debug build)
* To port the game to more platforms, such as Windows (including older versions), Linux, WebGL, Android, and macOS. Currently we have ports for:
* Windows 10/8/7
* Windows XP/Vista

**We will not do the following:**
* Add features added in or after Java Edition Beta 1.8
* Backport features from versions newer than 0.9.0
* Add The Nether or The End (probably)
* Add Herobrine
* Add support for Minecraft Java or Minecraft Bedrock servers. (although LAN play with original MCPE clients will be supported for as long as possible)
* Modify the project structure
Note: The original mcpe01_canada.apk does not work on newer Android devices. A port of this likely will.

## Building
### Windows (VS 2022)
This is simple enough - just open the project and compile.

To compile, you will **need the Microsoft Platform SDK and the DirectX (June 2010) SDK**. After that, follow the same steps as
the VS2022 build. (open the minecraftcpp_vs2010.sln project instead of the minecraftcpp.sln project).
**Note!** If you are running from within VirtualBox, disable mouse integration (absolute mouse), or the camera won't work properly.
### WebAssembly
First of all, place the `assets` folder into the `platforms/sdl/` directory.
The game will use the assets from within the `game/` directory. So put your assets there if you want to build for wasm.
Then run the `build-wasm` script corresponding to your platform (`-.sh` on linux/WSL, `-.bat` on windows).
The output files will be in `./wasm/dist`, but you need to upload them to a web host (localhost works too) to use. (problem with Emscripten)

## Have seams when playing?
I've had texture seams when playing Minecraft Classic, ClassiCube and this recreation of Minecraft PE. If seams bother you, and you are using an NVIDIA graphics card,
go to the NVIDIA Control Panel, then in "Manage 3D Settings", change "Antialiasing - Mode" to "Application Controlled".

## Notes on assets
The terrain.png and related textures appear to have stayed the same between the E3 demo and the final release for Xperia PLAY. It appears to have been fetched before
Java Edition Beta 1.4's release. This can be seen because the cookie's texture is missing. (it was added in Java Edition Beta 1.4)

## Known bugs
### Patched bugs
1. Due to lack of initialization of memory, fire can potentially burn normally inflammable blocks. See [this video](https://www.youtube.com/watch?v=3hrz7KK2EJs) for a demo.
2. Due to `SHAPE_FIRE` not being implemented, fire is invisible in this version. Fire rendering was backported from v0.7.1 and can be disabled with the `ORIGINAL_CODE` define
3. Due to `GL_BLEND` being disabled, the hotbar renders as fully opaque.
4. Memory is leaked when leaving a world with particles in it.
5. Stairs are invisible when held. To fix this, a fix has been backported from v0.1.1j
6. If the game is left on for approximately 1,242 days, the level will freeze, but the GUI will still be interactable.
The bugs can be "un-patched" by defining `ORIGINAL_CODE`. This allows compilation of an incomplete and mostly accurate recreation of MCPE for Xperia Play.
### Unpatched bugs
1. Particles with render texture 3 are invisible.
2. Potential freeze in `Entity::move`. If z_1 is between -0.04f and 0.04f, the game may freeze.
3. In `Particle::render`, the offset (`C_MAGIC_1`) is slightly larger than 1.0f / 16.0f. It's probably meant to be _smaller_ than 1.0f / 16.0f.
4. Ice doesn't properly cull faces, except on the y axis.
5. Fire is not extinguished on the server side.
6. Due to inaccuracies in level generation, some blocks may be different in multiplayer between a player on this version, and a player on the original MCPE.
## Enhancements
The original Minecraft: Pocket Edition had some missing details that make it feel like MCPE. Here are some enhancements that have been done:
* (`ENH_ENTITY_SHADING`) Make entity models have primitive shading
* (`ENH_SHADE_HELD_TILES`) Make in-hand block items have shading
* (`ENH_FIX_INVIS_STAIRS`) Fix 16x16x16 chunks of stairs rendering as invisible
* (`ENH_ALLOW_AO`) Allow enabling ambient occlusion (smooth lighting) using a hotkey (F4)
* (`ENH_TRANSPARENT_HOTBAR`) Allow the hotbar to be transparent. (See patched bugs #3)
* (`ENH_INSTA_BREAK`) Allow instant breaking of blocks
* (`ENH_CAMERA_NO_PARTICLES`) Hide particles from a camera's view. This hides the smoke particles that the camera emits, creating a clearer picture
* (`ENH_USE_JAVA_LIGHT_RAMP`) Use Minecraft: Java Edition Beta 1.6's light ramp code instead of the original (max brightness was only 0.8 in early versions of MC:PE for whatever reason)
* (`ENH_RUN_DAY_NIGHT_CYCLE`) Allow the day/night cycle to run
* (`ENH_ENABLE_9TH_SLOT`) Allow the 9th slot of the hotbar to be used instead of the unusable elipses (...)
* (`ENH_USE_OWN_AO`) Use a custom ambient occlusion engine (looks the same but fixes some corners)
* (`ENH_ADD_OPTIONS_PAUSE`) Add an "Options" button to the pause menu
* (`ENH_EXTRA_ITEMS_IN_INV`) Add extra items to a 5th row in the creative inventory
* (`ENH_HIGHLIGHT_BY_HOVER`) Highlight buttons when hovering over them instead of when using arrow keys
* (`ENH_ALLOW_SAND_GRAVITY`) Allow sand to fall
* (`ENH_USE_GUI_SCALE_2`) Use a GUI scale of 2 instead of 3 which looks better on PC (temporary)
* (`ENH_ALLOW_SCROLL_WHEEL`) Allow use of the scroll wheel to change selected inventory slots
Some of them can be turned on/off in `GameMods.hpp`, but the enhancement system is being phased out.
### Known bugs with enhancements
1. The camera's white overlay is fully opaque in shaded entity mode.
## Mods
In addition to enhancements, optional modifications to the base game were made. These mods are disabled by default but can be enabled in `GameMods.hpp`.
* (`MOD_USE_FLAT_WORLD`) Use a flat world instead of regular world generation (probably broken)
* (`MOD_USE_BIGGER_SCREEN_SIZE`) Use a bigger screen size of 1280x720 instead of 854x480
* (`MOD_DONT_COLOR_GRASS`) Don't tint the top of grass tiles with a different color (like Classic)
All enhancements (and more) that are available in the decomp version are turned on by default, but only some of them can be disabled, and the GameMods.hpp file used
to control them is deprecated and will be removed. Check the decomp version's repository for a partial list of enhancements that were added to the game.
