包路径：com.badlogic.gdx.physics.box2d.Body
类名称：Body
方法名：resetMassData

Body.resetMassData介绍

[英]This resets the mass properties to the sum of the mass properties of the fixtures. This normally does not need to be called unless you called SetMassData to override the mass and you later want to reset the mass.
[中]这会将质量特性重置为装置的质量特性之和。除非调用SetMassData以覆盖体量，并且以后要重置体量，否则通常不需要调用此函数。

代码示例

代码示例来源：origin: dozingcat/Vector-Pinball

public static Ball create(World world, float x, float y, float radius,
    Color primaryColor, Color secondaryColor) {
  Body ballBody = Box2DFactory.createCircle(world, x, y, radius, false);
  ballBody.setBullet(true);
  // Default is radius of 0.5, if different we want the mass to be the same (could be
  // configurable if needed), so adjust density proportional to square of the radius.
  if (radius != 0.5f) {
    ballBody.getFixtureList().get(0).setDensity((0.5f*0.5f) / (radius*radius));
    ballBody.resetMassData();
  }
  return new Ball(ballBody, primaryColor, secondaryColor);
}
