[LayaAir3][3.3] Laya.Area2D APi不可用

IDE中可以按照官方文档实现=inheritLaya=inherit.Camera2D和=inheritLaya=inherit.=inheritCamera2D
但是无法在脚本中动态创建Camera2D
官方文档：

[code]=inherit=inheritconst =inherit{ regClass=inherit, property =inherit} =inherit= Laya=inherit;



=inherit=inherit=inherit@=inheritregClass=inherit(=inherit)
