i know for sure screen shake wouldn't fudge up the shooting. that was something the devs talked about with weapon recoil. the whole feel of GE64 was that bond was a super steady handed super spy. and if we had lots of recoil affecting the shots, it makes things feel a bit to much like CS which isn't the direction we want to go.
small detail things like shaking the screen and does it affect the shooting, are really difficult nit picky design decisions that we are working through a lot of the time. the team eventually picks a direction to go then we release, and hope the community digs it.
I'm not sure exactly how something like screen shake gets done, but i think its a combination of code, and animation, or it could be just straight code.
the way i want screen shake to work, is sort of in a semi realistic way, to have mild screen shake around things like explosions, or when getting hit really hard from gunshots. but to have the recoil from the gun work really fluidly and smoothly so it doesn't feel like your going out of control when you hold the trigger down on the RCP90. half the fun of the original game is just dumping your clip at an opponent, and not having to really worry about recoil.
right now the team hasn't really talked to much about how screen shake is going to work out, cause we are getting ready for the episode 2 update, which hopefully wont total kill the mod like the infamous multifire causing SDK update.
