Body.getWorldCenter介绍

[英]Get the world position of the center of mass. Note that the same Vector2 instance is returned each time this method is called.
[中]获取质心的世界位置。请注意，每次调用此方法时都返回相同的Vector2实例。

代码示例

private void renderBox (Body body, float halfWidth, float halfHeight) {
  // get the bodies center and angle in world coordinates
  Vector2 pos = body.getWorldCenter();
  float angle = body.getAngle();
  // set the translation and rotation matrix
  transform.setToTranslation(pos.x, pos.y, 0);
  transform.rotate(0, 0, 1, (float)Math.toDegrees(angle));
  // render the box
  renderer.begin(ShapeType.Line);
  renderer.setTransformMatrix(transform);
  renderer.setColor(1, 1, 1, 1);
  renderer.rect(-halfWidth, -halfHeight, halfWidth * 2, halfHeight * 2);
  renderer.end();
