On Firefox and Chrome you can also hit "CTRL+SHIFT+I" to open the inspection page, then simply select "Console" of the tabs. Anyways, this it said: 
> java.lang.RuntimeException: (JavaScript) TypeError: $this is null
Do you have a method named "Crate_act" in which you set the image of the actor?
Their is no method named 'Crate_act'. But yes their is a class named Crate and i created a condition in which if certain classes gets close to the crate then it will create a loop in which it will continuously change its(crate) image again and again I used instance of crate class in MyWorld...B....EnemyTank....EnemyTank1.....Tank

Why don’t you share it via Greenfoot? You can add a license of you are worried, google for „MIT License“
What is all this about? The source code is already public and you can download it.

@Roshan123: In the Crate class, please replace lines 11 and 12 with this: 
        {
            System.out.println("Changing crate image of crate " + this);
            setImage("crate1.png");
        }
Then reupload the scenario and tell me.

Well actually this wasn't supposed to fix it, just debug what's going on...

You can try to remove the print statement, maybe it was just a compiling error. If it does not work again then you can at add this line instead: 
 Crate c = this;
That should have the same effect.

When I meant compiler error, I meant that there may have been a point in which this did not work (also in the app) and maybe you fixed it, but it did not properly compile into the .class file. This stuff happens sometimes in Greenfoot. Because it wasn't compiled, the change wasn't actually applied, but maybe you thought it was and uploaded it. If you then changed your code a bit more or just reopened the window it may got compiled properly so it would not happen in the app.

As usual the answer is....u were correct. Yet now its working properly even if the statement is removed. Thanks a lot for it!!!!!
