getSpeedSquared

该方法返回移动实体的速度的平方。

参数

该方法没有参数。

返回值

返回值为浮点数,代表移动实体的速度的平方。

示例

const entity = new MovingEntity();
const speedSquared = entity.getSpeedSquared();
console.log(speedSquared); // 输出移动实体的速度的平方

实现细节

速度的平方表示为x方向速度的平方加上y方向速度的平方。在该方法中,首先获取当前速度向量,然后计算x方向速度的平方和y方向速度的平方,最后将它们相加得到速度的平方。

异常

该方法没有异常。
