Question

I’m developing a game in Android and Java. In android I am using andengine for sprite image and i was able to rotate in all directions.

  int bikeFrame:
//bikeFrame++,bikeFrame--

bikeSprite.setRotation(bikeFrame);

I want to make the game in j2me also. But in j2me we have only four methods to rotate angle

(TRANS_MIRROR,TRANS_MIRROR 90,TRANS_MIRROR 270,TRANS_MIRROR 180)..

If i take images as frames I am still not getting smooth animation.

How to rotate sprite image in all angles in j2me?

Answer 1

See this thread, omarhassan123 created a code snippet that should allow you to rotate the image by any angle you like.

There is a library called J2ME ARMY KNIFE that provides all sorts of image manipulation techniques, you can get it here.

Also, see this question:
Image rotation algorithm

Another idea: decompile a game called Flexis Extreme. They do a lot of image rotation in real time so you could try to find out how they did it.
