@mariq_rasyid29, please start a discussion thread on your issue. Explain in detail what you want to accomplish. Show any related codes.

I would be interested to see how you coded this. It is not simple code. How much help did you get for this? I created a working model of it and realized how involved it was. I only used Actor objects for the clickable boxes. I thought that having actors for the main grid would just make things more difficult to deal with.

Two issues: (1) color box of current color should be inactive (or at least not count as a step when clicked); (2) a static array is preventing a clean reset.

@AnJoMorto, are you not creating them with a true boolean? addObject(new Enemy(), x, y, true);

@Roshan123, adding of collection png not currently working properly. Been that way for some time now. Note my latest collection had issues as well.

Field declaration: GreenfootSound background_music; In constructor: if (background_music == null) { background_music = new GreenfootSound("Background_music.mp3"); }

@SwaggyXiao, please refer to my Scrolling Tutorial scenario on image scrolling (see main text and link at bottom on "Actor follow scrolling code"). The scenario is located at: https://www.greenfoot.org/scenarios/18226

Scaling and re-scaling an image will usually distort and eventually "destroy" an image. Better would be to copy the image and scale it once; then go back and forth setting the appropriate image.
