Hi, may be in wrong place so mods be free to move. I am currently building a J2ME mobile phone game for project. It is a basic car racing game, but when a car collides with another car, i want my phone to vibrate. I cant seem to find functions for this to work and books are not great. Im using a sonyerricson aswell. Can find Nokia vibrating methods but it still throws up errors on the emulator. Any ideas Thanks
