linear velocityproblem

I have an FPS, but when i shoot, i cant get the bullets to have a linear velocity when i add them,

can any one explain this, am i missing something

Perhaps you could explain further? Are you using logic bricks or python or both?

What logic are you using?

I am guessing you are using Blender 2.43?? First thing with Linear Volcity is that you need the object to be Dynamic. Then you might also need to turn on the Local Transformation.
See if that works for you. Hope it helps.

Yes, most likely your bullet is not dynamic. If you need it to stay straight, counter-balance the gravity with a +Z LinV force.
