[Suggestion] Population Sync

Population Sync



I am not sure whether this has been suggested before, however after a quick forum search I didn't find anything like this.



It would just be a great thing?to have the default?San Andreas population while playing online!







How would it work?



Every client will just let the GTA:SA default population spawning logic be, and for each ped that is spawned by it, sync it with the server. When two clients?are close to each-other, an algorithm selects the client in charge to sync the population. The peds will also be automatically transferable from a client to another based on latency and other variables.?



Basically, the client with the best conditions?(I will call it master) creates the peds, gets their info (skin, position, speed, animations, weapons, and everything), and sends that info to the server.



The other clients (I will call them?slaves) will simply get this data from the server, and create simple peds that don't follow the logic of their own game, but instead, use the received data. Every single ped will have a unique id on the server.?



In the case of ped driving vehicles, every time the client generates a vehicle for a ped to drive, it will inform the server, which will then keep track of that vehicle until the ped despawns.







TL;DR Basically, like in FiveM.







Server functions and callbacks



Notice: This is just a prototype, and functions might be incorrect?(e.g. I didn't use output/reference?params nor return tags?to simplify reading).

Code:

// enable or disable the feature altogether (if disabled, peds will not be generated by the clients'?games)



TogglePopulation(bool:toggle);







// sets the density multiplier?of population for all players



// 1.0 = default (1x)



SetPopulationDensity(Float:density);







// given a certain client, gets all the peds that are streamed in for it



GetPlayerStreamedPeds(playerid);







// given a certain client, gets all the peds that are being controlled by it



GetPlayerOwnedPeds(playerid);







// will get all peds that are known to the server



GetAllPeds();



// returns whether a ped is valid

IsValidPed(Ped:ped);



// gets a ped's owner (player)

GetPedOwner(Ped:ped);



// gets the ped pool's?size

GetPedPoolSize();







// gets a ped's position



GetPedPosition(Ped:ped);



// gets a ped's facing angle

GetPedFacingAngle(Ped:ped);







// gets a ped's vehicle



GetPedVehicleId(Ped:ped);



// gets the ped's current weapon

GetPedWeapon(Ped:ped);



// returns whether a certain ped is streamed-in (visible) for a certain player

IsPedStreamedIn(Ped:ped, playerid);



// gets a ped's skin model

GetPedSkin(Ped:ped);



// gets a ped's interior

GetPedInterior(Ped:ped);



// gets a ped's health

GetPedHealth(Ped:ped);



// gets a ped's body armor

GetPedArmour(Ped:ped);



// gets a ped's [url=https://www.grandtheftwiki.com/Ped_Type]type[/url]

// eg:?CIVMALE or?COP

// could be used to check whether a ped is a cop for example

GetPedType(Ped:ped);



// gets a ped's [url=https://gtamods.com/wiki/Pedstats.dat]stats[/url]

// eg:?STAT_TOUGH_GUY or?STAT_TAXIDRIVER

GetPedStats(Ped:ped);



// gets a ped's vehicle id

GetPedVehicleId(Ped:ped);



// gets a ped's velocity

GetPedVelocity(Ped:ped);



// gets a ped's weapon skill level

GetPedSkillLevel(Ped:ped, skill);



// gets a ped's current animation index

GetPedAnimationIndex(Ped:ped);







//-------------- callbacks ---------------



// called when a ped was created/spawned

// creatorid is the player that synced the ped for the first time

// in a subsequent step, that ped's ownership?may have been transferred to another player

OnPedSpawn(Ped:ped, creatorid);



// called when a ped has died

// killerType is either "ped" or "player" (or none), and killerid contains the id of one of those two entities

OnPedDeath(Ped:ped, killerType, killerid, reason);



// called when a ped enters a vehicle

OnPedEnterVehicle(Ped:ped, vehicleid);



// called when a ped exits a vehicle

OnPedExitVehicle(Ped:ped, vehicleid);



// called when a ped is streamed in for a player

OnPedStreamIn(Ped:ped, forplayerid);



// called when a ped is streamed out?for a player

OnPedStreamOut(Ped:ped, forplayerid);



// called when a ped gives damage to another ped or player

OnPedGiveDamage(Ped:ped, damagedType, damagedId, Float: amount, weaponid, bodypart);



// called when a ped gives damage to another ped or player

OnPedTakeDamage(Ped:ped, issuerType, issuerid, Float: amount, weaponid, bodypart);

That's pretty much everything that came to my mind at this moment. Of course more functions could be made.



What do you guys think of this suggestion? Think about how radically differents servers will be with population in them :)
