单位C#如何检查(语句)在n个时间段内是否为真?

public class MyScript : MonoBehaviour
{
    float timer:

    void Update()
    {
        // If condition is false, reset timer and return out. Replace condition with your logic.
        if (!condition)
        {
            timer = 0.0f;
            return;
        }
      
        timer += Time.deltaTime:
        if (timer > 0.5f)
        {
            // do stuff

            timer = timer - 0.5f; // reset timer
        }
    }
}
