示例1: create
import com.badlogic.gdx.physics.box2d.Body; //导入方法依赖的package包/类
/**
* Creates a RotatingGroup by computing the distance and angle to center from the first
* element ID in the ids array.
*/
public static RotatingGroup create(Field field, String[] ids, double cx, double cy, double speed) {
FieldElement element = field.getFieldElementById(ids[0]);
Body body = element.getBodies().get(0);
Vector2 position = body.getPosition();
double radius = Math.hypot(position.x - cx, position.y - cy);
double angle = Math.atan2(position.y - cy, position.x - cx);
return new RotatingGroup(ids, cx, cy, radius, angle, speed);
}
示例2: update
import com.badlogic.gdx.physics.box2d.Body; //导入方法依赖的package包/类
@Override
public void update(float gameTime) {
// implement the world physics
world.step(BOX_STEP, BOX_VELOCITY_ITERATIONS, BOX_POSITION_ITERATIONS);
