You should not have booleans in your world -- not to keep same as actors.

Basically I am making a quiz. I want the quiz to move on to another question after clicking a true-false button. I would also like it to give me a score out of 5 after all 5 questions.

Oh, ok. Thanks to both of u for helping me out)

And then, there are the typos. I meant, use: <Code Omitted>

Got it! I just wanted to know if I could do that in Greenfoot because in Unity, for exemple, there's a function to do that. Anyways, I solved the problem by following what you guys suggested. Thanks :)

Yes -- to be sure. Another condition for a block to move depends on its x-coordinate in the world. Actually, that would be two conditions -- one for left edge and one for right.

if you want to check if both string are the same, do this <Code Omitted>if you want to check the value of s1 and change s2, do this <Code Omitted>

thanks this really helped

The whole problem was the font I installed in my pc, so I have to use another one. But this is working for me. <Code Omitted>Thanks for the help, everyone.

Stars class can be simplified to this: <Code Omitted>

The more actors you have, the slower your scenario will get, yes. In the case of Game of Life, there should be life in a cell or not. So there shouldn’t be more than one actor in a cell. However, you don’t need to use actors for the cells. Since each actor is only a boolean representation (or 0 and 1) showing with an image, you can also have an array in your world and draw the world background based on the 0’s and 1’s in the array.

you can do two things : 1 : getImage().setTransparency(0); this will just make the image opacity to 0 2 : setImage((GreenfootImage)null); this will set a null image, completely blank

Sounds like you are trying to construct your world. That is, place the initial actors into your world. That would be coded in your World subclass, either in the constructor method or in a method called from that constructor (usually called prepare).

Thanks a lot!
