我想在屏幕上移动一个简单的矩形。我已经定义了我的对象并隔离了更新和渲染的任务。我知道我必须在Gamerenderer中放一些东西,但不知道用什么代码来引用我的对象。任何帮助将非常感激。感谢
我的对象:
package com.mygdx.gameobjects;
import com.badlogic.gdx.math.Rectangle;
public class Egg {
private Rectangle rect;
public Egg(){
rect = new Rectangle(0, 0, 50, 50);
}
public void update(float delta) {
rect.x++;
if (rect.x > 137) {
rect.x = 0;
}
}
public Rectangle getRect() {
return rect;
}
}
我的游戏世界:
package com.mygdx.gameworld;
import com.badlogic.gdx.Gdx;
import com.mygdx.gameobjects.Egg;
public class GameWorld {
Egg rect = new Egg();
public void update(float delta) {
Gdx.app.log("GameWorld", "update");
rect.update(delta);
}
public Egg getRect() {
return rect;
}
}
GameRenderer
package com.mygdx.gameworld;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.glutils.ShapeRenderer;
public class GameRenderer {
private GameWorld myWorld;
private OrthographicCamera cam;
private ShapeRenderer shapeRenderer;
public GameRenderer(GameWorld world) {
myWorld = world;
cam = new OrthographicCamera();
cam.setToOrtho(true, 136, 204);
shapeRenderer = new ShapeRenderer();
shapeRenderer.setProjectionMatrix(cam.combined);
}
public void render() {
Gdx.app.log("GameRenderer", "render");
Gdx.gl.glClearColor(0, 1, 1, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
shapeRenderer.begin(ShapeRenderer.ShapeType.Line);
shapeRenderer.setColor(255 / 255.0f, 109 / 255.0f, 120 / 255.0f, 1);
shapeRenderer.rect(xxxxxxxxxxxx);
shapeRenderer.end();
}
}
我需要在括号之间放置什么来查看我的矩形,即xxxxxx应该替换为什么?
答案 0 :(得分:1)
放
Rectangle eggRect = myWorld.rect.getRect();
在上面的行。这将获得对矩形的引用。然后将xxxxx替换为相关值:
(eggRect.x, eggRect.y, eggRect.width, eggRect.height)
方法重载,如果你想
,你还可以为颜色添加参数吗?
