Java on Mobile Devices J2ME
#1

i developed a game using game canvas and is for midp 2.o nokia 60 series phones it is working fine in 60 series emulator but it is too slow in the nokia 6600 device any please help me to solve this problem (i am using a long tiled layer of 35X5 each cell of 30X30 pixel size)

I use my own Tile system and have done a ton of work to only draw the tiles that change and I only redraw offscreen maps on tile boundaries. It’s quite complex, but I can run it on very low power phones and it tends to work pretty well. If you are redrawing all the tiles on the screen (or the whole map for that matter!) it just isn’t going to perform well on a phone. I’m not sure what the internal implementation looks like for the TileMap class, but I’m sure your mileage is going to vary between vendors.

I’m just saying that TileLayer might be part (or most) of the problem with performance. You may have to implement your own TiledLayer so you have more visibility into the actual problem.

In general you should expect significant slow down between the emulator and the actual device. The trick is to make your code do as little as possible to get the job done.
