class_name PlayerReenterLock
|
|
|
|
#### 目前无需全局，仅需跟随 ground
|
|
#### 因此无需在 exit 时重置锁，也无需推迟计数
|
|
#### 因为 PlayerReenterLock 生命周期与 ground 一致
|
|
|
|
####### PlayerReenterLock 系统提供了以下特性 #############
|
|
# 可重入性：每个事件可以多次锁定/解锁，通过计数器管理
|
|
# 全局状态追踪：使用静态变量追踪整体锁定状态 [无需启用]
|
|
# 生命周期管理：自动处理节点进入/退出场景树的情况 [无需启用]
|
|
# 错误保护：防止过度释放，并在出现问题时发出警告
|
|
# 调试支持：可选的调试模式输出详细信息
|
|
# 便捷方法：提供同时锁定/解锁两种状态的方法
