News article explaining some of the shotgun game logic used in ZMBE 1.2

About Shotguns

Normally in FPS games shotguns use a very simple accuracy pattern: There is a set "cone" of accuracy that is centered around the crosshair. For ZMBE we decided to go a bit deeper. Instead of the simple method explained, our code works a bit different:

Player presses fire ----> Initial cone center is displaced ----> Shell is being fired (on a set cone around this new displaced center) ----> Player view is shaken a bit + Player view center ends up displaced after the shot

This servers several purposes: Different shotgun characteristics are taken into account, like barrel length which then determines damage, base accuracy, spread and amount of kick the player experiences. This difference the defines the usage of each shotgun. For example a sawn-off baikal has a very high spread and low accuracy, which makes it a very useful close-combat weapon because you can hardly miss a zombie trying to claw you. On the other side the 28" barrel Remington 870 Wingmaster Express has excellent accuracy and an ultra tight spread, which makes it great for long range shooting, but you might actually miss a fast moving zombie coming close to you.

Interesting, That would have been my guess as to how the shotty's work. Nice modifications.

OH WOW AMAZING. Not, the cone is still the same, all you're doing is shaking the view, that does NOT affect the cone at all. To affect the spray/cone you have to do more mathematical calculations. Don't try to look smart, because this made me laugh.

V = w/h=1024/2; C = RandomInt(45,50)/2; v+=c*2; Hardly amazing.

No. the cone is different in size, direction and offset for each shotgun. We are shaking, and displacing the view + offsetting the cone center and spread. So you better not try to look smart.

Exactly, you're not affecting the cone what soever, setting an offset to the view does not affect the cone. So you better not try to look smart, hence why I even +3 votes because people know I'm right.

Do more mathematical junctions then make a proper post.

I also said, don't try to look smart, not better not. What are you gonna do to me? Blow me up for having brown hair green eyes and having correct views on things?

I think you did not get my last post. Our code displaces the aim center (which the cone uses) before the shell fires. And once you play the mod you can easily verify it. For example the Remington shotgun has a very tight spread and if you do some target shooting you will see that each shot group, while being very tight, is not centered around the absolute view center. This means even though it has a really tight spread it is not ultra accurate because spread center is not the same as aiming center.

Also look at the screenshot on the newspost. Each shot group was fired while aiming at the same spot on the target.

You're still not affecting the cone, how can I get it into that big lump of a brain of yours?

Yes it is affecting the cone. Also do not start discussions with people if you can not keep personal insults to yourself

I'd... Kinda agree with PottehUK. Not in the same way, but this doesn't really seem amazing to me either. It hardly sounds different either. It seems to me you just took shotguns from one game or another, generalized it, shoddily explained it, then explained yours in a bit more detail trying to make it sound better.

If you could actually cite references and other games in which the 'simple method' was used, I might be impressed. As it is, you've just arrogantly accused other games of using a method you seem to be assuming, not to mention in your comment above you're saying that games apply the same template for every kind of shotgun in their game?
