Inputs

CS:GO Weapon:

SetAmmoAmount <integerRedirectInput/integer> (only in )

For guns, sets the number of bullets in the active magazine. Does nothing for grenades.
Every value behaves like its congruent value in the range 0-255 in modulus 256 (e.g. -255 and 257 behave like 1 etc.). When set to 0, the owner may start reloading automatically, if possible. Other values congruent to 0 (-256, 256, 512, ...) might cause undefined behavior. Values congruent to -1 (mod 256) make the ammo numbers disappear. If set to a value outside the weapon's clip size, reloading might deliver unexpected results.

SetReserveAmmoAmount <integerRedirectInput/integer> (only in )

For guns, sets the number of bullets in reserve for reloading, clamping at the weapon's maximum (e.g. 90 for the weapon_ak47).
For grenades, sets their count, clamping at the current maximum depending on the convars ammo_grenade_limit_*; When setting to 0 or below while holding the grenade, the player no longer owns any, but the viewmodel stays.
Negative values make a gun's ammo display disappear and reloading is impossible.

ToggleCanBePickedUp <booleanRedirectInput/boolean> (only in )

Toggles whether the weapon can be picked up by players. Visually, nothing changes and there is no event if picking up fails. Hover texts like "[E] Swap for AK-47" remain in both cases.
