LibGdx 棋盘

Question

我尝试创建一个棋盘，只是 libGdx 中的棋盘，但由于某种原因，我不能。 我仍然错过了国际象棋的另外两行。 我将向您展示我的代码，也许您可以在我的代码中找到问题，如果没有，我可以轻松接受另一种解决方案。

package com.mygdx.game;

 import com.badlogic.gdx.ApplicationAdapter;
 import com.badlogic.gdx.Gdx;
 import com.badlogic.gdx.Input.Keys;
 import com.badlogic.gdx.graphics.Color;
 import com.badlogic.gdx.graphics.GL20;
 import com.badlogic.gdx.graphics.OrthographicCamera;
 import com.badlogic.gdx.graphics.Pixmap;
 import com.badlogic.gdx.graphics.Texture;
 import com.badlogic.gdx.graphics.Pixmap.Format;
 import com.badlogic.gdx.graphics.g2d.SpriteBatch;
 import com.badlogic.gdx.graphics.g2d.TextureRegion;

 import com.badlogic.gdx.maps.tiled.TiledMap;
 import com.badlogic.gdx.maps.tiled.TiledMapTileLayer;
 import com.badlogic.gdx.maps.tiled.TiledMapTileLayer.Cell;
  import com.badlogic.gdx.maps.tiled.renderers.OrthogonalTiledMapRenderer;
  import com.badlogic.gdx.maps.tiled.tiles.StaticTiledMapTile;
  import com.badlogic.gdx.utils.ScreenUtils;
   import com.badlogic.gdx.utils.viewport.Viewport;

public class MyGdxGame extends ApplicationAdapter {
SpriteBatch batch;
Texture img;
private OrthographicCamera camera;
private OrthogonalTiledMapRenderer render;
private final static int width = 100, height = 80, layercount = 8;
private TiledMap map;

@Override
public void create() {
    float w = Gdx.graphics.getWidth();
    float h = Gdx.graphics.getHeight();

    camera = new OrthographicCamera(w, h);

    Pixmap pixmap = new Pixmap(100, 80, Format.RGBA8888);
    pixmap.setColor(Color.WHITE); // add your 1 color here
    pixmap.fillRectangle(0, 0, 80, 80);

    pixmap.setColor(Color.BLACK); // add your 2 color here
    pixmap.fillRectangle(0, 0, 80, 80);
    // the outcome is an texture with an blue left square and an red right
    // square
    Texture t = new Texture(pixmap);
    TextureRegion reg1 = new TextureRegion(t, 0, 0, 80, 80);
    TextureRegion reg2 = new TextureRegion(t, 80, 0, 80, 80);

    TiledMap map = new TiledMap();
    MapLayers layers = map.getLayers();
    for (int l = 0; l < layercount; l++) {
        TiledMapTileLayer layer = new TiledMapTileLayer(width, height, 80,
                80);
        for (int x = 0; x < width; x++) {
            for (int y = 0; y < height; y++) {
                Cell cell = new Cell();
                if (y % 2!= 0) {
                    if (x % 2 != 0) {
                        cell.setTile(new StaticTiledMapTile(reg1));
                    } else {
                        cell.setTile(new StaticTiledMapTile(reg2));
                    }
                } else {
                    if (x % 2 != 0) {
                        cell.setTile(new StaticTiledMapTile(reg2));
                    } else {
                        cell.setTile(new StaticTiledMapTile(reg1));
                    }
                }
                layer.setCell(x, y, cell);
            }
        }
        layers.add(layer);
    }
    render = new OrthogonalTiledMapRenderer(map);
    render.setView(camera);
    camera.translate(Gdx.graphics.getWidth() / 2,
            Gdx.graphics.getHeight() / 2);
}

@Override
public void dispose() {
    render.dispose();
    map.dispose();
}

private static final float movmentspeed = 5f;

@Override
public void render() {

    Gdx.gl.glClearColor(1, 1, 1, 1);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    camera.update();
    render.setView(camera);
    render.render();

    if (Gdx.input.isKeyPressed(Keys.LEFT)) {
        camera.translate(-movmentspeed, 0);
    } else if (Gdx.input.isKeyPressed(Keys.RIGHT)) {
        camera.translate(movmentspeed, 0);
    } else if (Gdx.input.isKeyPressed(Keys.UP)) {
        camera.translate(0, movmentspeed);
    } else if (Gdx.input.isKeyPressed(Keys.DOWN)) {
        camera.translate(0, -movmentspeed);
    }
}

@Override
public void resize(int width, int height) {

}

@Override
public void pause() {
}

@Override
public void resume() {
}
}

这是我的代码。 如果可以的话，我需要尽快解决这个问题...

Answer 1

您第二次致电

pixmap.setColor(Color.BLACK); // add your 2 color here
pixmap.fillRectangle(0, 0, 80, 80);

覆盖第一个设置的颜色，因为您正在写入同一区域。

此外，当您创建第二个纹理时，它的宽度为零。

TextureRegion reg2 = new TextureRegion(t, 80, 0, 80, 80);

在迭代棋盘的嵌套循环中，您可以简化查找棋盘的交替单元类型以

if ((x+(y*8)) % 2 = 0 ) {
//Cell is bottom left square color
} else {
//Cell is the other colour
}

虽然稍后为特殊效果生成棋盘很不错，但您也可以从平铺编辑器中导入一个，然后您可以对它的外观进行更多试验。 平铺 map 加载器绝对不会像您想象的那样痛苦，它们非常短，实际上是一个片段，这里有一个书面加载器https://gamefromscratch.com/libgdx-tutorial-11-tiled-maps-part-1-simple-正交图/

（同样与此Pixmap pixmap = new Pixmap(100, 80, Format.RGBA8888);它比您使用的区域更大。）
