Hi, I am working on my game and was wondering how to give points when an object is clicked by the mouse/cursor.

use the mouseClicked(java.lang.Object obj) method in the greenfoot class, like this:
?
1
2
Greenfoot.mouseClicked(this); //this is if you put it in the object that's to be clicked on
Greenfoot.mouseClicked(Object obj); //this is if you put it elsewhere (such as in the world class). over here my class is named object but that's arbitrary.

Line 1 returns a boolean value and is equivalent to:
?
1
true; // or false;
which does nothing by itself (actually, both lines). But, by using it as a condition to score, you put it in an if statement:
?
1
if (Greenfoot.mouseClicked(this)) { << increment score here >> }

Thanks for commenting both of you (danpost I see you on every discussion possible btw and great games) , but, would I need anything else for this to work properly or just this. I have not stated score anywhere yet and this is a fresh scenario. So, I was wondering if you guys could help me state this and score together. Thanks (I am sort of new to this, but I have stated score a few times)

What I gave is basically it. It might take a little more doing to actually display the score, however.

?
1
if(Greenfoot.mouseClicked(this)) {1}
^^ Seen as not a statement
?
1
if(Greenfoot.mouseClicked(this)) {<<1>>}
^^ Illegal expression What I am thinking is that I have not stated score anywhere, which is not allowing me to do this OR I am missing something very big as I have had no experience with this.

You need to increment your score there. Since I do not know what you are using for your score or where your score field is, I cannot say exactly what code you would use there.

It could be as simple as that if your score field were in that class. But, it could have been more complicated, like:
?
1
((MyWorld)getWorld()).getScore().add(1);
if your score was elsewhere.

Ok, thanks. I was looking through all of your methods and demos and I saw one game kind of with the same score idea. https://www.greenfoot.org/scenarios/9571 Is this how simple your code was?

So, I think the score might be working, but I need to show it on a counter. Would it be possible for you to help me on that aswell. Thanks (Sorry for asking so many questions)

Maybe you should take a look at my Value Display Tutorial scenario.
