Is there any place in your codes where an EnemyTank object is made to move other than the EnemyTank class?

Sorry I don't understand It removes the text of another class and not of EnemyTank class and also doesn't remove the actor class

Yesterday i was thinking about it But the main reason which stops me to think like that is; I think by creating another class will take some more time to load it and also it may lag by creating a lot many classes I think i have 14-19 classes in my scenario (I don't remember well)

If its not the reason then i may create another class as soon as possible And also tell me what is the real size of my scenario Is it size or size on disk

Image and sound files are usually what makes up the majority of the size of large scenarios. The number of classes and number of dependencies between them can influence load time; but, again, image and sound files are a much greater influence.
