1061: Call to a possibly undefined method gotoAndStop through a reference with static type Class

Question

I see where i was going wrong however when i change the instance name like you said i 1120: Access of undefined property snakePart. all of this code btw is at document class level and the movieclips are in the library not on stage

Answer 1

Is the instance on the stage? When you name instances, don't name them identical to your class name. Flash gets confused because you're importing a class called SnakePart but you have an instance called ... SnakePart. Instead, name it something else (ie snake_part) or at least change the case (ie snakePart - not recommended as it can lead to some issues debugging).

Change your instance name, change this code snakePart.gotoAndStop(2) and you should be gravy. Unless your actionscript is in a part of the flash (ie on another frame or not in the Document class level - preferred and recommended) that the object hasn't been instantiated yet.

To instantiate a library movieclip, try this in your Document class level, inside your constructor :

var snakePart:SnakePart = new SnakePart();
addChild(snakePart);

Answer 2

您正在类定义“ SnakePart”上调用gotoAndStop而不是类的实例 ，如var snake_part:SnakePart = new SnakePart();

Answer 3

它确实做到了，实际上，您尚未在要调用的类中定义静态方法，想必您打算调用该类的实例。
