nah, having a particle fire option doesnt truly make alot of sense, remember when you make a game you dont make it for yourself alone wink its not that it needs to be removed just that, comparing quality to performance, its a bit slow

- by camera effects i didnt mean DOF, i meant camera shaking and bobbing
- by all directions i mean, i should be able to RUN diagonally also and left and right, not just forward and back
- you player is too rigid with the camera, meaning, like hes attached to it, maybe you could have him turn just a bit slower than the camera

i was thinking about helping you out by allowing you to use the anims shown here:

however, they werent designed to be realistic and trying to use them in a realistic world might break that world, so maybe you could tell me your plans for this game and how long you plan on working on it
