# NotEnoughMinecraft
\nDid you ever want to play Minecraft inside of Minecraft without installing any mods on the client? NO??? Anyways, now you can!<\/p>\n
<\/p>\n
## Setup
\n1. Install fabric-api and polymer.
\n2. This mod requires a server resource pack. The easiest way to host this is by enabling polymers autohost
\n3. Give yourself a computer `\/give @s not-enough-minecraft:computer` and place it down.
\n4. Right-click on a computer to start playing<\/p>\n
## Controls
\n– The input for movement, jumping and sprinting is the same as your default inputs
\n– Breaking, placing, dropping and picking blocks also use your default inputs
\n– Use the scroll wheel or number keys to navigate the hotbar
\n– You can right-click *(to start)* using an item. *You can right-click again to finish using the item.*
\n– You can sneak to stop playing and exit the computer
\n– You can press your inventory key to toggle a fps counter<\/p>\n
*Because this is a serverside-only mod, it is limited to inputs the client sends to it!*<\/p>\n
## How it works
\nWhen playing, a fake player is created and added to the server. Each tick an image is rendered using a server-side
\nraycasting renderer from tomalbrc.
\nThe rendered image is then displayed to the client using a custom screen item, where each pixel can be colored
\nusing custom model data colors.<\/p>\n
## Config
\nThe config is located at `config\/not-enough-minecraft.json`.<\/p>\n

## Licenses
\nThis mod uses the rendering code from https:\/\/github.com\/tomalbrc\/camera-obscura. All code in the
\n`de.tomalbrc.cameraobscura` package is licensed under LGPL-3.0-only.
\nThe idea of using a custom screen item to display the rendered image is taken from https:\/\/github.com\/tomalbrc\/BlockBoy-Arcade,
\nwhich is licensed under MIT<\/p>\n
## Limitations
\n*This is a quite cursed\/hacky weekend project.* <\/p>\n
Rendering on the server like this is quite inefficient and will increase CPU usage significantly, which can cause
\nissues on lower end setups.<\/p>\n
We don’t have any way to compress or optimize the screen data for sending it over the network, so we have to send the
\nraw pixels each frame. This can lead to an increased network load when viewing computer screens.
\nYou can expect 300-400 KiB\/s increase per screen with default minecraft network compression.<\/p>\n
Fake players will behave like regular players in almost all aspects, such as world interactions, commands,
\nplayer list, player data and more.
\nEach player gets their own unique fake player companion, which has the same UUID, but with the lowest bit increase by one.<\/p>\n","protected":false},"excerpt":{"rendered":"
