    Collapsible trees with J2ME 

    Trees are not often used within j2me applications, but since it’s quite always a mess to deal with them, here’s a ready to use component for managing and drawing collapsible/scrollable trees :)
    j2me collapsible trees

    As usual, you can go to Forum Nokia Wiki for the full source code: J2me Collapsible Trees, or go to the emulator page to have a first look at a sample midlet using this component.

    Customizing game sprites with J2ME 

    You know, my great passion are games, and here’s a first game-related tutorial :)

    Often in games a nice feature to give to users it the possibility to customize their own character, for example changing colors of the different parts (hairs, eyes, shirt, and so on).

    To support this features there are 2 possibilities:

    • Include a different image for each color of each different part
    • Replace colors by code

    The second options will save you the effort to create these multiple images, and will strip down your JAR size. Also, it will allow you to support a lot more colors.

    You can see a simple midlet showing how this can be done with simple code on the emulator page

    For the full source code you can visit the Forum Nokia Wiki page: J2ME Customizing Game Sprites Color
