[英]Wait for instruction without stopping while loop
I designed a C++ application that represents an mechanical arm. 我设计了一个代表机械臂的C ++应用程序。 The simulation is running inside a while loop.
仿真在while循环内运行。 I have the following class Motherboard that interacts with the simulation
我有以下与仿真互动的类主板
class Motherboard
{
public:
void receiveInstruction(double angle);
}
I have as well an event receiver that waits for keyboard instruction during the simulation. 我还有一个事件接收器,它在模拟过程中等待键盘指令。 I won't copy the full class but here is the interesting part (the prefix irr comes from the fact that I am using Irrlicht 3D engine) :
我不会复制完整的类,但这是有趣的部分(前缀irr来自我正在使用Irrlicht 3D引擎的事实):
case irr::KEY_SPACE:
// Do something
return true;
case irr::KEY_RETURN:
std::cin << angle
motherboard->receiveInstruction(atof(angle))
return true;
where angle is of type char[] and atof converts a string into a double. 其中angle为char []类型,atof将字符串转换为双精度型。 When I enter the RETURN key on my keyboard the simulation freezes until i complete typing the angle instruction.
当我在键盘上输入RETURN键时,模拟冻结,直到我完成角度指令的输入。
How shall I proceed to let the simulation running while I am typing the instruction, and send the instruction as soon as I am done entering the information ? 我在输入指令时如何继续运行模拟,并在输入信息后立即发送指令? Are threads unavoidable ?
线程是不可避免的吗? (I am running on Windows)

是的,似乎是不可避免的,或者至少是最优雅的方式。
