[JAVA] Help and Tutorials in developing J2ME game

[Scirwode]

I'm currently approaching my final semester for my course and one of the subjects require me to create a final product for evaluation. One of the conditions placed was that you must have a client for the product you're developing unless that product is very hard for a client to accept. A Java phone game is one of them and I'm very interested in choosing that for my final assignment as I do not want to deal directly with a client.

My knowledge on Java is very shallow and limited to Dim and so on. I would like to know if there are websites who can show me how to develop simple to advance Java games for phones? I would also like to know what are the advantages and disadvantages of Java Phone games and if it is difficult to develop. Please help me as this is very important to me as I must pick a title and then prepare a proposal for my lecturers to be approved. I would be grateful if you could assist me and I thank you for your time and patient in reading my post.

Apparently, J2ME is like a crippled version of Java without the vast libraries. You have to extend the mobile interface class and go from there. every pixel has to be drawn by code, so that can be tricky also.

If you do find any resources, please let us know, because I'd like to programme some J2ME also :)

Tools:

Java Wireless Toolkit 2.2 (needs JRE installed).

http://java.sun.com/products/sjwtoolkit/download-2_2.html *Registration required.

When you have installed it, go to folder where you installed it.

Under apps folder, you'll find examples (incl. games).

You use J2ME Wireless Toolkit to create the project and manage it.

You'll have to use some text editor (notepad isn't so bad) to create the .java files.

And save them to WTK22PATH\apps\YOURAPP\src.

Then Build and Run the app in builtin emulator.

Sites:

I am currently using WTK and EditPlus.

Thank you :D ! But is it correct that to develop a game for a phone, it is called J2ME? I have a Sony Ericsson K700i so I'm hoping to use it for my work. Also, I use notepad to write out my Javascript then run it using command prompt. Is there a program that allows me to write Javascript and display mistakes I've made and colour code them, such as in Dreamweaver?

but for you notepad mod I would sugest

http://www.textpad.com/products/textpad/sc...hots/index.html

does a lot of things should be helpfull

also you might want to look around www.sourceforge.net for some of the text editors

Thank you for that :yes: . Though I'm still looking for a good Java editor, hopefully I'll find one that will suit my needs. I believe there is one called Blue something, though I can't remember :wacko: . Is there anyone else who can help me as I'm really at a disadvantage here :cry: . Can someone provide me tutorials or worksheets that will help me develop a Java phone game. Is there also a difference between J2ME and the Java used in phone?

Programming for the phone.

I actually found a good blog http://www.armadilloaerospace.com/n.x/johnc/Recent%20Updates about phone programming :unsure: :unsure:

*its under {Cell phone adventures}

That text editor does the underlining and everything, ;) I guess you looking for something more then that?

for development: Just go to netbeans.org and download the IDE and the Mobility Pack and you're good to go :)

tutorials: http://www.jasonlam604.com/ (it has a nice ebook and tips)

http://today.java.net/pub/a/today/2005/02/09/j2me1.html (starts with J2ME midlets and advances to the Game API)

if you want your game to work on your mobile, you'll have to adjust the gaming screen to the size of your mobile. The emulator is too big and if you code for it it's probably not going to fit. If you have a PDA then it probably won't be much of an issue.

You'll also have to pay attention to the CLDC and MIDP versions that your mobile supports and when you are working in netbeans adjust these accordingly in you project properties. The emulator always uses the latest and your mobile might not support them.

In my experience, it's quite easy to develop games with J2ME.

I don't think your limited experience with Java will be a negative factor if you alreay have a solid knowledge of C++ (or C# or C for that matter :p).

Thank you, SIG :D ! I have start reading and downloading as it will take some time for me to familiarise myself with all this. And no, I have no experience whatsoever with C++ or C# (I do know OpenGL and the like :p ). Again, thank you :yes: .

Thank you, Wilhelmus :woot: ! I've only just started reading and then you give me this. I think it's a sure thing that I'm developing a Java Game for a phone for my assignment :yes: .
