MapEngine

Description

MapEngine is a map library plugin for paper servers. It provides a simple API to create maps with custom content. Using lightweight and asynchronous techniques, MapEngine has a very low impact on server performance.

Features

• Pipelined API for custom pipelines
• Asynchronous rendering
• Completely packet based
• Optional dithering (Floyd-Steinberg)
• Groups as z-layer interpretation for saving immense network traffic
• Per player buffering, only the changed pixels are sent to the player
• Optional packet bundling prevents tearing
• Drawing utilities (text, components, lines, triangles, rectangles, circles, ellipses, polygons)

Usage

MapEngine has to be added as a dependency to the plugin.yml regardless of the build system used.

Example

public class Bar {

    // getting the api instance
    private static final MapEngineApi MAP_ENGINE = Bukkit.getServicesManager().load(MapEngineApi.class);

    public void foo(BufferedImage image, BlockVector cornerA, BlockVector cornerB, BlockFace facing, Player viewer) {
        // create a map display instance
        IMapDisplay display = MAP_ENGINE.displayProvider().createBasic(cornerA, cornerB, facing);
        display.spawn(viewer); // spawn the map display for the player

        // create an input pipeline element
        // this object can also be used to draw simple shapes and text
        IDrawingSpace input = MAP_ENGINE.pipeline().createDrawingSpace(display);

        // draw the image to the input pipeline element
        input.image(image,0,0);

        // draw a triangle
        input.triangle(0, 0, 10, 10, 20, 0, 0xff0000ff);

        // add a player to the pipeline context,
        // making the player receive the map
        input.ctx().receivers().add(viewer);

        // enable floyd-steinberg dithering
        input.ctx().converter(Converter.FLOYD_STEINBERG);

        // enable per player buffering
        input.ctx().buffering(true);

        // flush the pipeline
        // the drawing space can be reused
        input.flush();
    }
}
