I have been looking over tons of websites trying to get everything together that I need for programming Java J2ME, specifically for my SPH-a660/VI660. I have been learning to program normal Java at a community college and have a little game experience in various other languages, and want to move into mobile game programming. I have still seem to be missing quite a bit though, such as the SDK. I'm not sure what I need for an SDK or where to find it (Sun doesn't seem to offer the actual SDK). Also, is it possible to use BlueJ to write the source (since that is what I learned on)? Not quite as related to programming, I can't seem to find the data transfer cable anywhere. Is there a certain site that I should look for it on? Thanks for the help!

The only SDK you need is the Sun WTK (Wireless Toolkit), which can be downloaded from Sun.

I'm not familiar with BlueJ, but any decent Java development environment should be fine to write code in. What's less clear is whether you'll be able to build and test your MIDlets from that IDE; if not, you'll have to use WTK for building and testing.

I seem to recall that many Samsungs don't do cable-based provisioning; you may need to do OTA (over-the-air) provisioning.

I just wanted to agree with Sneftel and add a few things...
Here is a link to the latest WTK from sun, which is basically all you need to start developing. You can write your code in anything you want, but personally I use the free version of JCreator.

You may have seen it already but this site has a nice little intro to J2ME that might clear up any questions you have. here

Good Luck!

And a cable won't do you any good. Samsung phones don't allow installation like that. Only over the air.

I didn't realize that included everything I need, I was expecting something more like J2SM. It doesn't seem to include any documentation though, about the J2ME only functions.

> I seem to recall that many Samsungs don't do cable-based provisioning; you may need to do OTA (over-the-air) provisioning.

That would explain why I couldn’t find the cable anywhere. Are there any guides to doing OTA? I'm guessing it is more complicated than just uploading it to a website and accessing it from your phone, right?

> but personally I use the free version of JCreator.

When I looked into that software I didn't see that there was a freeware version. I will definitely try it.

Thanks for the help everyone!

You're not far off. The only part you missed is where you set the MIME types for jad and jar in the web-server. Click for more in depth explanation.

As i recently have jumped into j2ME myself, i can tell you what i did.
(caution I develope on a mac)

Well First I read this nice little article sitting on GameDev.net:
An Introduction to Developing for Mobile Devices Using J2ME/MIDP (Part 1)

This gave me the basic idea of how things are going to work out, and so i set it up on my PC.

*This is as far as i made it on the Windows Platform*

So the next steps i would take is installing Eclipse then run a google search on J2ME integration with Eclipse lots of stuff comes up.

Now for the mac user...

Went on over to the URL http://www.mpowerplayer.com/developer/ and grabed me up the mpowerplayer SDK.

I then installed such software.

I then browsed on over to the Developer Forums on mpowerplayers website.
S very nice gentleman posted an xCode template to get things up and running, Xcode Template

The only thing i haven't tryed was downloading to my phone... Nothing worth trying out on the phone yet.

Good Luck

      without going into any details I am looking for any articles or blogs or advice about city building and RTS games in general. I tried to search for these on my own, but would like to see your input also. I want to make a very simple version of a game like Banished or Kingdoms and Castles,  where I would be able to place like two types of buildings, make farms and cut trees for resources while controlling a single worker. I have some problem understanding how these games works in the back-end: how various data can be stored about the map and objects, how grids works, implementing work system (like a little cube (human) walks to a tree and cuts it) and so on. I am also pretty confident in my programming capabilities for such a game. Sorry if I make any mistakes, English is not my native language.
      Thank you in advance.

      So I'm currently working on a rogue-like top-down game that features melee combat. Getting basic weapon stats like power, weight, and range is not a problem. I am, however, having a problem with coming up with a flexible and dynamic system to allow me to quickly create unique effects for the weapons. I want to essentially create a sort of API that is called when appropriate and gives whatever information is necessary (For example, I could opt to use methods called OnPlayerHit() or IfPlayerBleeding() to implement behavior for each weapon). The issue is, I've never actually made a system as flexible as this.
      My current idea is to make a base abstract weapon class, and then have calls to all the methods when appropriate in there (OnPlayerHit() would be called whenever the player's health is subtracted from, for example). This would involve creating a sub-class for every weapon type and overriding each method to make sure the behavior works appropriately. This does not feel very efficient or clean at all. I was thinking of using interfaces to allow for the implementation of whatever "event" is needed (such as having an interface for OnPlayerAttack(), which would force the creation of a method that is called whenever the player attacks something).
      Here's a couple unique weapon ideas I have:
      Explosion sword: Create explosion in attack direction.
      Cold sword: Chance to freeze enemies when they are hit.
      Electric sword: On attack, electricity chains damage to nearby enemies.
      I'm basically trying to create a sort of API that'll allow me to easily inherit from a base weapon class and add additional behaviors somehow. One thing to know is that I'm on Unity, and swapping the weapon object's weapon component whenever the weapon changes is not at all a good idea. I need some way to contain all this varying data in one Unity component that can contain a Weapon field to hold all this data. Any ideas?
      I'm currently considering having a WeaponController class that can contain a Weapon class, which calls all the methods I use to create unique effects in the weapon (Such as OnPlayerAttack()) when appropriate.

      Hi fellow game devs,
      First, I would like to apologize for the wall of text.
      As you may notice I have been digging in vehicle simulation for some times now through my clutch question posts. And thanks to the generous help of you guys, especially @CombatWombat I have finished my clutch model (Really CombatWombat you deserve much more than a post upvote, I would buy you a drink if I could ha ha). 
      Now the final piece in my vehicle physic model is the differential. For now I have an open-differential model working quite well by just outputting torque 50-50 to left and right wheel. Now I would like to implement a Limited Slip Differential. I have very limited knowledge about LSD, and what I know about LSD is through readings on racer.nl documentation, watching Youtube videos, and playing around with games like Assetto Corsa and Project Cars. So this is what I understand so far:
      - The LSD acts like an open-diff when there is no torque from engine applied to the input shaft of the diff. However, in clutch-type LSD there is still an amount of binding between the left and right wheel due to preload spring.
      - When there is torque to the input shaft (on power and off power in 2 ways LSD), in ramp LSD, the ramp will push the clutch patch together, creating binding force. The amount of binding force depends on the amount of clutch patch and ramp angle, so the diff will not completely locked up and there is still difference in wheel speed between left and right wheel, but when the locking force is enough the diff will lock.
      - There also something I'm not sure is the amount of torque ratio based on road resistance torque (rolling resistance I guess)., but since I cannot extract rolling resistance from the tire model I'm using (Unity wheelCollider), I think I would not use this approach. Instead I'm going to use the speed difference in left and right wheel, similar to torsen diff. Below is my rough model with the clutch type LSD:
      speedDiff = leftWheelSpeed - rightWheelSpeed; //torque to differential input shaft. //first treat the diff as an open diff with equal torque to both wheels inputTorque = gearBoxTorque * 0.5f; //then modify torque to each wheel based on wheel speed difference //the difference in torque depends on speed difference, throttleInput (on/off power) //amount of locking force wanted at different amount of speed difference, //and preload force //torque to left wheel leftWheelTorque = inputTorque - (speedDiff * preLoadForce + lockingForce * throttleInput); //torque to right wheel rightWheelTorque = inputTorque + (speedDiff * preLoadForce + lockingForce * throttleInput); I'm putting throttle input in because from what I've read the amount of locking also depends on the amount of throttle input (harder throttle -> higher  torque input -> stronger locking). The model is nowhere near good, so please jump in and correct me.
      Also I have a few questions:
      - In torsen/geared LSD, is it correct that the diff actually never lock but only split torque based on bias ratio, which also based on speed difference between wheels? And does the bias only happen when the speed difference reaches the ratio (say 2:1 or 3:1) and below that it will act like an open diff, which basically like an open diff with an if statement to switch state?
      - Is it correct that the amount of locking force in clutch LSD depends on amount of input torque? If so, what is the threshold of the input torque to "activate" the diff (start splitting torque)? How can I get the amount of torque bias ratio (in wheelTorque = inputTorque * biasRatio) based on the speed difference or rolling resistance at wheel?
      - Is the speed at the input shaft of the diff always equals to the average speed of 2 wheels ie (left + right) / 2?
      Please help me out with this. I haven't found any topic about this yet on gamedev, and this is my final piece of the puzzle. Thank you guys very very much.
