# Roads2DGenerator

Algorithm for map generation of roads in 2D

(collapse wave function???)

Forked and improved from https://github.com/sea-kg/roadmapgen2d

Example of generated structs (30x30 points):

## Usage

1. Copy `src/Roads2DGenerator.*` to your project

```cpp

#include "Roads2DGenerator.h"

...

int width = 30;

int height = 30;

Roads2DGenerator road2gen(width, height);

road2gen.generate(0.7);

// use a table with true/false

std::vector> vPixelMap = road2gen.exportToPixelMap();

for (int x = 0; x < width; x++) {

    for (int y = 0; y < height; y++) {

        if (vPixelMap[x][y]) {

            // has road

        } else {

            // no road

        }

    }

}

// or use a table with directional elements

std::vector> vTable = exportToTable();

for (int x = 0; x < width; x++) {

    for (int y = 0; y < height; y++) {

        std::string sRoad = vTable[x][y];

        if (sRoad == "cross") {

            // ╬

        } else if (sRoad == "horizontal") {

            // ═

        } else if (sRoad == "vertical") {

            // ║

        } else if (sRoad == "right-down") {

            // ╔

        } else if (sRoad == "left-down") {

            // ╗

        } else if (sRoad == "right-up") {

            // ╚

        } else if (sRoad == "left-up") {

            // ╝

        } else if (sRoad == "left-up-down") {

            // ╣

        } else if (sRoad == "right-up-down") {

            // ╠

        } else if (sRoad == "left-right-down") {

            // ╦

        } else if (sRoad == "left-right-up") {

            // ╩

        } else {

            // nope

        }

    }

}
