我正在制作2D游戏,现在正在前进 box2Dlights部分的集成。
这是另一张图片,我不渲染灯光。现在没有灯。 我需要将Box2D和Box2Dlights的碰撞混合在一起。 请注意 :
setToOrtho((16 - 1.875f) / Gdx.graphics.getHeight())
,其中16是图块大小。所有代码都很复杂,因此我现在仅发送GameScreen和GameMap类:
@Override
public void show() {
InstanceVars inst = InstanceVars.getInstance();
inst.world = new World(new Vector2(0, 0f), true);
inst.engine = new Engine();
inst.handler = new RayHandler(inst.world);
LevelCreator creator = new LevelCreator("level_def.cfg");
try {
gameWorld = creator.createNewLevel();
gameWorld.start();
} catch (FileCorruptedException e) {
e.printStackTrace();
}
}
@Override
public void render(float delta) {
gameWorld.render();
}
@Override
public void resize(int width, int height) {
gameWorld.resize(width, height);
}
@Override
public void dispose() {
gameWorld.dispose();
InstanceVars.getInstance().dispose();
}
用于 GameScreen.java 和
private World physWorld = InstanceVars.getInstance().world;
private Box2DDebugRenderer physRender = new Box2DDebugRenderer();
private OrthographicCamera cam = new OrthographicCamera();
private RayHandler lights = new RayHandler(physWorld);
private PlayerController controls;
private float STD_ZOOM = ((float) CELL_SIZE + 16) / Gdx.graphics.getHeight();
private Body playerBody;
public GameMap() {
cam.zoom = STD_ZOOM;
}
public void start() {
GameObject player = (GameObject) getProperties().get("ent_player");
playerBody = player.getComponent(PhysicsComponent.class).getBody();
controls = new PlayerController();
Gdx.input.setInputProcessor(controls);
physWorld.setContactListener(new CollisionInteractor(InstanceVars.getInstance().engine));
PointLight light = new PointLight(lights, 1000, Color.GOLDENROD, 500, playerBody.getPosition().x, playerBody.getPosition().y);
}
public void render() {
updatePlayer();
physWorld.step(1/60f, 8, 2);
updateCamera();
physRender.render(physWorld, cam.combined);
// lights.updateAndRender();
}
private void updatePlayer() {
if (controls.up) playerBody.setLinearVelocity(playerBody.getLinearVelocity().x, -controls.speed);
else playerBody.setLinearVelocity(playerBody.getLinearVelocity().x, controls.down ? controls.speed : 0);
if (controls.down) playerBody.setLinearVelocity(playerBody.getLinearVelocity().x, controls.speed);
else playerBody.setLinearVelocity(playerBody.getLinearVelocity().x, controls.up ? -controls.speed : 0);
if (controls.left) playerBody.setLinearVelocity(-controls.speed, playerBody.getLinearVelocity().y);
else playerBody.setLinearVelocity(controls.right ? controls.speed : 0, playerBody.getLinearVelocity().y);
if (controls.right) playerBody.setLinearVelocity(controls.speed, playerBody.getLinearVelocity().y);
else playerBody.setLinearVelocity(controls.left ? -controls.speed : 0, playerBody.getLinearVelocity().y);
}
public void resize(float width, float height) {
STD_ZOOM = ((float) CELL_SIZE - 1.875f) / Gdx.graphics.getHeight();
cam.setToOrtho(true, width, height);
}
private void updateCamera() {
cam.position.set(playerBody.getPosition(), 0);
cam.update();
}
public void dispose() {
super.dispose();
physWorld.dispose();
physRender.dispose();
}
GameMap.java 。 如果您需要更多详细信息,请不要害怕询问。 我不能独自解决问题。
