我正在制作一个用于计算素数的非常基本的node.js应用程序，它使用无限循环连续计算素数，我想通过使用void update()
{
glm::vec3 front;
front.x = cos(glm::radians(Yaw)) * cos(glm::radians(Pitch));
front.y = FrontGo.y;
front.z = sin(glm::radians(Yaw)) * cos(glm::radians(Pitch));
FrontGo = glm::normalize(front);
if (prewYaw > Yaw)
{
lastRotationDegree = glm::acos(glm::dot(FrontGo, PrevFrontGo) / (glm::length(FrontGo) + glm::length(PrevFrontGo)));
}
else
{
lastRotationDegree = -glm::acos(glm::dot(FrontGo, PrevFrontGo) / (glm::length(FrontGo) + glm::length(PrevFrontGo)));
}
PrevFrontGo = FrontGo;
prewYaw = Yaw;
glm::vec3 frontl;
frontl.x = cos(glm::radians(Yaw)) * cos(glm::radians(Pitch));
frontl.y = sin(glm::radians(Pitch));
frontl.z = sin(glm::radians(Yaw)) * cos(glm::radians(Pitch));
FrontLook = glm::normalize(frontl);
Right = glm::normalize(glm::cross(FrontLook, wUp));
Up = glm::normalize(glm::cross(Right,FrontLook));
}
和{{1}为每个素数添加一个时间码}变量，但是void ProcessKeyboardP(Player_Movement direction, float deltaTime)
{
float velocity = MovementSpeed * deltaTime;
if (direction == FORWARD_P)
Position += FrontGo * velocity;
if (direction == BACKWARD_P)
Position -= FrontGo * velocity;
if (direction == LEFT_P)
Position -= Right * velocity;
if (direction == RIGHT_P)
Position += Right * velocity;
}
没有运行，我怀疑这是由于无限循环造成的，是否有任何修复/替代方法？这是我的代码：
setintervalprimecalc（primes）
答案 0 :(得分：1)
考虑将您的代码放在具有较小超时的间隔中，而不是无限循环。循环会停止执行，让一个循环永远运行对您而言效果不佳。另外，正如@Bergi所指出的，在间隔的每次迭代上运行Date.now()会比跟踪单独的计时器更好。
