在以下脚本中，gameObject从起点到终点，然后从终点到终点一次。如何在无限循环中运行它？

app = Flask(__name__)
CORS(app)

logger = logging.getLogger(__name__)

@app.route("/conversations/default/respond",methods=['POST'])
def run_weather_bot(serve_forever=True):
    logging.basicConfig(level="ERROR")
    interpreter = RasaNLUInterpreter('C:\\xxxx_nlu\\models\\nlu\\default\\weathernlu')
    action_endpoint = EndpointConfig(url="http://xxx.xx.xx.xxx:5055/webhook")
    agent = Agent.load('C:\\xxxx_nlu\\models\\dialogue', interpreter=interpreter, action_endpoint=action_endpoint)

    rasa_core.run.serve_application(agent,channel='cmdline')

    return agent


if __name__ == '__main__':

    app.run("xxx.xx.xx.xxx",5005,debug=True)

Answer 1

行

target = origin

覆盖您原来的target值，并且该值“永远丢失”。

您可以继续使用它，但是应该这样做

if (transform.position == target)
{
    target = origin;
    origin = transform.position;
}

因此您已存储了原始目标（==当前transform.position）值，以便下次切换。

或者，您也可以通过一个简单的标志来做到这一点：

private bool backToOrigin;

void Update()
{
    // if flag is true travels to origin otherwise to target
    transform.position = Vector3.MoveTowards (transform.position, backToOrigin ? origin : target, speed * Time.deltaTime);

    // if one of the two positions is reached invert the flag
    if (transform.position == target || transform.position == origin)
    {
        backToOrigin = !backToOrigin;
    }
}

transform.position = Vector3.MoveTowards (transform.position, backToOrigin ? origin : target, speed * Time.deltaTime);

是写作的单行速记

if(backToOrigin)
{
    transform.position = Vector3.MoveTowards (transform.position, origin, speed * Time.deltaTime);
}
else
{
    transform.position = Vector3.MoveTowards (transform.position, target, speed * Time.deltaTime);
}

Answer 2

只需将目标和原点存储在单独的变量/字段/属性中，然后使用第三变量。第三个用于移动，而不是分配目标变量，请使用第三个。创建一个新的if子句，在其中对原点进行测试，然后将原点应用于第三个var。它会在目标和原点之间切换

如何使此脚本循环运行？
