换成鼠标移动,周围光线变亮ASSISTANT
要实现一个使用鼠标输入控制物体移动的效果,并且当光源靠近鼠标位置时周围光线变亮,我们可以修改输入处理和光线颜色。这里是一个更新后的版本:
### 更新后的代码
```java
package com.nanshaws;
import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Color;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.math.Vector2;
import com.badlogic.gdx.physics.box2d.Body;
import com.badlogic.gdx.physics.box2d.BodyDef;
import com.badlogic.gdx.physics.box2d.Box2DDebugRenderer;
import com.badlogic.gdx.physics.box2d.PolygonShape;
import com.badlogic.gdx.physics.box2d.World;
import box2dLight.PointLight;
import box2dLight.RayHandler;
public class LightAndMoveExample extends ApplicationAdapter {
OrthographicCamera camera;
World world;
Body body;
RayHandler rayHandler;
PointLight pointLight;
Box2DDebugRenderer debugRenderer;
@Override
public void create() {
camera = new OrthographicCamera(48, 32);
camera.position.set(0, 16, 0);
camera.update();
world = new World(new Vector2(0, 0), true);
debugRenderer = new Box2DDebugRenderer();
BodyDef bodyDef = new BodyDef();
bodyDef.type = BodyDef.BodyType.DynamicBody;
bodyDef.position.set(0, 16);
body = world.createBody(bodyDef);
PolygonShape shape = new PolygonShape();
shape.setAsBox(1, 1);
body.createFixture(shape, 1);
shape.dispose();
RayHandler.useDiffuseLight(true);
rayHandler = new RayHandler(world);
rayHandler.setAmbientLight(0.1f, 0.1f, 0.1f, 1f);
pointLight = new PointLight(rayHandler, 128, new Color(1, 1, 1, 1), 10, 0, 0);
pointLight.attachToBody(body);
pointLight.setSoftnessLength(1f);
}
@Override
public void render() {
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
handleInput();
world.step(1/60f, 6, 2);
rayHandler.setCombinedMatrix(camera);
rayHandler.updateAndRender();
debugRenderer.render(world, camera.combined);
}
private void handleInput() {
// 通过鼠标位置控制物体
if (Gdx.input.isTouched()) {
float mouseX = Gdx.input.getX();
float mouseY = Gdx.input.getY();
Vector2 worldPosition = camera.unproject(new Vector2(mouseX, mouseY));
body.setTransform(worldPosition.x, worldPosition.y, body.getAngle());
// 根据距离调整光照亮度
float distance = body.getPosition().dst(worldPosition);
float intensity = Math.max(0.5f, 1.5f - distance * 0.1f);
pointLight.setColor(new Color(intensity, intensity, intensity, 1));
}
}
@Override
public void dispose() {
rayHandler.dispose();
world.dispose();
debugRenderer.dispose();
}
}
```
### 代码变化说明
1. **鼠标输入控制**:
- `if (Gdx.input.isTouched())` 检查鼠标是否被按下。
- 通过 `Gdx.input.getX()` 和 `Gdx.input.getY()` 获取鼠标的位置。
- 使用 `camera.unproject()` 将屏幕坐标转换为世界坐标。
- 使用 `body.setTransform()` 方法将物体移动到鼠标位置。
2. **光线亮度调整**:
- 计算物体与鼠标的距离:`body.getPosition().dst(worldPosition)`。
- 根据距离调整光照亮度:使用 `setColor()` 方法,调整 RGB 值以反映改变的亮度。距离越近,亮度越高。
这样,当你用鼠标点击并拖动时,物体会跟随鼠标移动,并且光源亮度根据与鼠标位置的接近程度进行调整。
