虚幻4引擎怎么用C++代码生成新的蓝图类

step_run = 0;
//tim_cnt = 5.2363 * ft / (sqrt(acc*N_MOTOR/2)); //(ft * sqrt(60)*0.676) / sqrt(acc*N_MOTOR/2);
tim_cnt = 7.7460 * ft / (sqrt(acc*N_MOTOR/2));
tim_rest = 0;
i = 0;
TIM3_Configuration(tim_cnt);
run_state = run_state_acc;
TIM_Cmd(TIM3,ENABLE);
step_done = 0;
while(step_done==0);
while(i
{
i++;
//tim_cnt_temp = tim_cnt;
//tim_cnt = tim_cnt - (2*tim_cnt+tim_rest) / (4*i+1);
//tim_rest = (2*tim_cnt_temp+tim_rest) % (4*i+1);
tim_cnt_temp = tim_cnt / ( sqrt((float)(i+1)) + sqrt((float)(i)) );
TIM3_Configuration(tim_cnt_temp);
