修改Python自动点击器delay变量不改变点击速度该如何解决？

故障原因分析 #

• 延迟修改不生效的核心原因：ClickMouse线程实例在初始化时就把全局delay的值复制给了实例属性self.delay，后续修改全局delay变量不会同步更新线程实例内的延迟参数，因此点击速度始终保持初始值。
• 潜在代码问题：存在命名冲突，你先后导入了mouse模块、又将鼠标控制器实例命名为mouse，覆盖了模块导入结果，虽然当前代码可运行，但极易引发后续逻辑报错。

修复方案 #

1. 让delay修改实时生效 #

直接修改线程实例的delay属性即可让延迟实时生效，你也可以增加快捷键动态调整点击速度。

2. 自定义sleep等待逻辑 #

你可以用高精度计时的忙等待实现自定义延迟，相比系统的time.sleep精度更高，更适合短延迟的自动点击场景，实现代码如下：

def custom_sleep(delay_seconds: float):
    # 使用perf_counter获取高精度系统时间
    start = time.perf_counter()
    while time.perf_counter() - start < delay_seconds:
        # 空循环等待直到达到指定延迟
        pass

注意：忙等待方案会占用1个CPU核心满负载运行，如果对延迟精度要求不高，仍然推荐使用原生time.sleep降低资源消耗。

修复后完整可运行代码 #
