This page describes a function made for one of the natively supported games. These functions are made with very specific purpose and provide no flexibility, so using them in custom projects is not recommended. Authors are encouraged to use one of the more generalized functions in custom projects. For example: A_FireBullets.

action void A_FireCGun()
Usage
Does the standard Chaingun attack. It plays the sound "weapons/chngun", runs the Flash state, and fires one bullet similar to A_FirePistol.
If vertical bullet spread for weapons is enabled, the function applies vertical spread in addition to the horizontal one.

}
Weapon weap = player.ReadyWeapon;

return;
A_StartSound ("weapons/chngun", CHAN_WEAPON);
State flash = weap.FindState('Flash');
if (flash != null)
{
// Removed most of the mess that was here in the C++ code because SetSafeFlash already does some thorough validation.
State atk = weap.FindState('Fire');
let psp = player.GetPSprite(PSP_WEAPON);
if (psp)
{
State cur = psp.CurState;
int theflash = atk == cur? 0:1;
player.SetSafeFlash(weap, flash, theflash);
}
}
}
player.mo.PlayAttacking2 ();
GunShot (!player.refire, "BulletPuff", BulletSlope ());
}
