Trying to understand the Pistol

Hi there. I was wondering if the regulars here could confirm some or all of the following, based on the DECORATE version of the Pistol code as listed on the ZDoom Wiki:

- When you press the button to fire the pistol, it first goes into 4 frames of "pre-fire", so that the gun doesn't fire straight away when you pres the button.

- After these 4 frames, the gun then fires the bullet, and displays the appropriate sprite for 6 frames, and then another sprite for 4 frames.

- At this point, it checks to see if you're still holding down the fire button. If you are, it goes through the {A4; Fire; B6; C4;} sequence again.

- If you aren't holding down the button when that check is made, then the gun goes into a "cool-down" state where you aren't able to fire again for an additional 5 frames.

- The code as shown does not account for the first bullet always being accurate.

Is there anything that I am understanding incorrectly?

That's not true - the A_Refire check also enables the weapon's inaccuracy after the first shot. That's just the way A_Refire works.

If that is true, then the code on the shotgun page would make it fire like a rifle with each first shot. I assume that the shotgun page is incorrect...

No, the shotgun page is also correct, as refire accuracy only applies to weapons that fire a single bullet per shot. If the bullet count in A_FireBullets is set to any number greater than 1, then it automatically turns it into a spread shot weapon. If the number is set to -1, only one bullet is fired, and that shot is never accurate.

Ok. I'll try to get used to this weirdness.

One final question: How is angle measured? Is it from center to edge or from edge to edge?

My guess is center to edge. I dunno really, I just fidn a value that suits my needs via experimentation.

Since I'm here, what exactly does this, "+WEAPON.WIMPY_WEAPON", do?

Bot AI stuffage, IIRC.

The WIMPY_WEAPON flag actually tells Doom not to auto-switch to that weapon when you're out of ammo unless there's nothing else. For example, I believe the Fist has WIMPY_WEAPON on it.
