偶然收集到的一个C语言源码

#include <airobot/c/SimpleRobot.h>

#define MOVE_VELOCITY 5
#define TURN_VELOCITY toRadians(3)
// 等待机器人转动指定的弧度
void waitforRadians(double radians);

/**
 * 每个单位时间都会触发
 */
void onTick(struct TickAction* action)
{
	while (1)
	{
		move(MOVE_VELOCITY);
		turn(TURN_VELOCITY);
		waitforRadians(PI * 2);

		move(MOVE_VELOCITY);
		turn(-TURN_VELOCITY);
		waitforRadians(PI * 2);
	}
}

void waitforRadians(double radians)
{
	int i;
	int times = (int) (radians / TURN_VELOCITY);
	for(i=0; i<times; i++)
	{
		delay();
	}
}							

/**

int main(int argC, char* argV[])
{
	tickHook = onTick;	
	return startup(argC, argV);
}
