将偏航保持在两个偏航范围内

Question

我试图阻止用户向左或向右转得太远，但在关闭我的支票时，偏航有时会从 0 变为 360。

我有一个主偏航，我想防止用户从主偏航改变他们的偏航 60/-60。主偏航是动态的，完全随机变化

这是我目前正在使用的代码（不能正常工作）

float playeryaw = passenger.yaw; //The user

float right = car.yaw + 60;
float left = car.yaw - 60;

if (right > 360) { //Some checks to insure the YAW isn't negitive or too high
    right -= 360;
} else if (right < 0) {
    right += 360;
}

if (left > 360) {
    left -= 360;
} else if (right < 0) {
    left += 360;
}

if (playeryaw < left) {
    playeryaw = left; 
} else if (playeryaw > right) {
    playeryaw = right;
}

基本上我想防止汽车的 driver 从右边或左边看得太远。

您需要确保right > left。所以你不能只更新一个界限。无论如何，我建议修改 playeryaw:

float playeryaw = passenger.yaw; //The user

//put playeryaw in the neighborhood of car.yaw
while(car.yaw - playeryaw > 180)
    playeryaw += 360;
while(car.yaw - playeryaw < -180)
    playeryaw -= 360;

float right = car.yaw + 60;
float left = car.yaw - 60;

if (playeryaw < left) {
    playeryaw = left; 
} else if (playeryaw > right) {
    playeryaw = right;
}

//put playeryaw in the desired range
while(playeryaw < 0)
    playeryaw += 360;
while(playeryaw > 360)
    playeryaw -= 360;

根据您使用的值，while语句可以切换为if（如果您可以确保值最多相差360°）。
