hey im tring to access an object called “block” on my stage and i put this inside a class that my player is using  
PLAYER CLASS

```auto
package {

	import flash.display.MovieClip;

	public class bot extends MovieClip
	{

		public function bot()
		{
			var cube = stage.getChildByName("block");
			if (cube.hitTestObject(this))
			{

			}
		}
	}

}

```

i got an error:  
TypeError: Error #1009: Cannot access a property or method of a null object reference.  
at bot()  
at flash.display::Sprite/constructChildren()  
at flash.display::Sprite()  
at flash.display::MovieClip()  
at flash.display::Sprite/constructChildren()  
at flash.display::Sprite()  
at flash.display::MovieClip()
