New BB trajectory

I've been working on a new BB trajectory for a while, and I finally found the right codes to adjust it.
And here is the result.

This is the old concept of firing a BB.
The BB would be fired from the exact center of your vision and then fall depending on the gravity and the speed.

This is the new firing concept, the BB will start aproxx at the tip of the gun and then travel towards the center of your vision. This means that the dot in reddotsights aren't correct at close range because the dot will still be in the center of your vision, just like IRL.

This is what it will look like when you fire the airsoftguns.
The BB will start a little lower than usually and then travel towards the center of your vision and then fall as you can see on my illustration.
Ive added a few pics below, but it's very hard to show on stills, so you might not get the idea.
