Here are pretty much all of the things we should be able to configure for ammo in PB2.5:
Ammo Crates: Ammo crates hold a certain amount of ammo and spawn on maps.
Amount of ammo in each crate (1 to infinite)
What weapons a crate can refill (Example: Set an ammo crate to refill Pistol CS-PRO and Assault Rifle CS-RC only)
Respawning (if set to true, respawns after a set amount of time, if false does not respawn after being used up)
Equipment shop:Where equipment is bought, which includes guns, ammo, and equipment like jetpacks. Hopefully can be configured to work during a map instead of always after you finish one, so ammo and such can be bought on the fly provided you actually find a shop in-game.
Price (Amount of credits/money/currency per ammo. Example: 4 credits per 20 CS-RC bullets)
Types of ammo sold (Self explanatory, what kinds of ammo can be solid and for what guns)
Guns:Guns should be more configurable, especially per-gun instead of more general rules like we currently have. Specifics include adjustable range, accuracy, magazine size, rounds per shot (shotguns), ammunition used per shot (for guns you want to have bad ammo efficiency), damage falloff, penetration, and pretty much any other way they can already be modified.
Amount of ammo per gun (Example: CS-RC spawning with 60 rounds, 30 of which are in the gun, or a CS-RC spawning with only 1 bullet.)
Amount of magazines per gun (Example: CS-RC spawning with two magazines for a total of 60, like above, but allows for uneven amounts of ammo to be added on top of magazines. Therefore this allows for a CS-RC with two magazines (60) plus 16 rounds on top (76). This is so map editors can put in a number of magazines while also having the choice to be specific with the amount of ammo a gun comes with. For those who want standard amounts of ammo, it is much easier to have a weapon spawn with four magazines worth of ammo as opposed to trying to find how many individual rounds that is.)
Magazine size (Determines the amount of rounds in the magazine per gun.)
Ammo Capacity (Determines max amount of rounds per gun total. Example: A CS-RC that can hold a total of 200 rounds.)
Shells (For shotguns only. If we can get some choice in regarding shells so stuff like the CS-DAZ doesn't reload all of its shells every single time you want to reload one shell, that'd be great)
Totally sure there's more so feel free to add on to this post.
