Simple Brainfuck Game Engine

An engine where the logic is written in brainfuck.

Notice

Due to the language's specifics the only available colors are black and white. A value may go as high as 255, but for the canvas, the only accepted values are 0 - black and >1 - white.

This is a feature, not a bug.

Also, in order to get input, you use ',LetterOfYourChoice', for instance

,w

In this code, if 'w' was clicked between globs (aka if 'w' was clicked between canvas update) the selected value will become 'w''s ascii code.

Setup

Here is what you need to do to use this engine.

git clone https://github.com/ImRanThereforeHail/BrainfuckGE.git
cd BrainfuckGe
cargo run --release main.bf

A "Hello world!" message should appear.

First steps

Head on to any file of your choice

The inner workings of the engine are very simple. You have an array of size 1024 which acts as a 32 x 32 grid in the canvas. (In future versions you should be able to adjust the size). If a value inside the array is greater than 0 its corresponding pixel will be white; else, the corresponding pixel will be black.

The brainfuck code runs in a loop;

Answering questions

• Can I have objects? You can! So long as said object isn't invisible (which is not supported) just assign a number from 0 to 255 as an alias to said object, and in the next iteration of the loop you'll know what pixel represents what.

Examples

This code paints the whole canvas white

+>*

This is because the code runs in a loop, so, in english:

add 1 to the current value, change to the value in the right, update screen, return to the beginning 

Thus, if you want to paint, for instance, 2 cells, it would have to be:

+>+*-<-

TODO

• Be able to change grid size (CAN'T DUE TO UNKNOWN GLITCH)

Done

• File to be used goes an argument, rather than always the main.bf
• Use '*' to update canvas
• Rewrite front-end (all in src/main.rs)
