Using your code, here it is. int i = 0 int score = i ; int frame = 0; void drawScore { GreenfootImage scoreBoard = new Image (dimensions,dimensions); //dimensions up to you scoreBoard.drawString(Integer.toString(score), 0, 0); //string placement should be have the x coordinate (first one) greater than 0 depending on string length and about half way down the image height so that you can see all letters setImage(scoreBoard); } void incrementScore() { frame = frame + 1; if(frame % 20 == 0) { //increase the % x to make the wait time longer i = i+1; }

It might be better, if you'd take a look at the documentation of this scenario. There you can see explanations of all the methods.

Hi, Although I've not read the book, this is pretty straight forward java. Basically: public Key(String keyName, String soundFile) is the constructor for the Key Actor. Basically, when you create a new Key, you do so by: new Key(<keyName>,<soundFile>); For example: new Key("A","whistle.wav"); Now, that constructing method, put's the string "A" into the class variable key and the sound file name into sound class varilable (lines 6 & 7). If you then look at line 28, the if statement looks to see if key pressed is the value in the key class variable (i.e. you constructed t

Ok, I will. I'll get back to you tomorrow. For now I have to go to bed though. it's 10:30 and I have school tmrw.

Omg! Now I understand the page, that Duta postet! xD Sry, but I read the page under stress, bevore school today morning and so I haven't thought so much! xD Now it's clear! I haven't thought about, that this was a String and so you need two backslashes instead of one. xD Thank you guys!

If you look in danpost's Bar.class, you'll see that there are the methods: - public void add(int amount) - public void subtract(int amount) You call these methods to add or subtract health. There are other ways to do this but here's one way: (1) Go to your world class. Add the following:

If the river is part of the world's background, you would have to either map the rivers and cross-check using the map, or check the color where the man moves. Move him, then check, If is has a high amount of blue (for the river) then back him up and turn him.

thx, so i will use greenfoot ;-)

sorry im danish try to translate as good as i can. for some very strange reason its working today. thak you for trying to help me.

Thanks davmac, again incredibly helpful. I do appreciate the corrections in the terminology; it definitely will help me in an exam :) ... On careful thought, I think I will opt for your first possible solution, seeing as the images are very small, so the inefficiency itself, for me, will be near to negligible. EDIT: ah, it didn't work! Well, lets try the seemingly long-winded alternative...

i did find it in the end :-) ty for your replay
