`CCarCtrl.h`
交通密度、随机车、脚本造车、AI 挂路网。和 [CPopulation](/docs/plugins/entities/population) / [CPathFind](/docs/plugins/entities/pathfind) 配套。
## 密度与计数
```cpp
static float& CarDensityMultiplier;
static unsigned int& MaxNumberOfCarsInUse;
static int& NumRandomCars;
static int& NumMissionCars;
static int& NumParkedCars;
static int& NumPermanentVehicles;
```
```cpp
// CCarCtrl::CarDensityMultiplier = 0.0f; // 少车
```
## 应急与警察车
```cpp
static unsigned int& NumLawEnforcerCars;
static unsigned int& NumAmbulancesOnDuty;
static unsigned int& NumFireTrucksOnDuty;
static bool& bAllowEmergencyServicesToBeCreated;
```
```cpp
CCarCtrl::bAllowEmergencyServicesToBeCreated = false;
```
## 脚本造车
```cpp
static CVehicle* CreateCarForScript(int modelid, CVector posn, unsigned char MissionCleanUpFlag);
static void SetCoordsOfScriptCar(CVehicle* pVehicle, float x, float y, float z, unsigned char arg5, unsigned char arg6);
static CVehicle* GetNewVehicleDependingOnCarModel(int modelID, unsigned char createdBy);
```
```cpp
// 模型已加载：
// CVehicle* v = CCarCtrl::CreateCarForScript(model, pos, 1);
```
## 随机生成
```cpp
static void GenerateRandomCars();
static void GenerateOneRandomCar();
static void GenerateEmergencyServicesCar();
static bool GenerateOneEmergencyServicesCar(unsigned int modelID, CVector posn);
```
```cpp
// 游戏主循环会调；ASI 一般只改密度/开关
```
## 挂路网
```cpp
static void JoinCarWithRoadSystem(CVehicle* pVehicle);
static bool JoinCarWithRoadSystemGotoCoors(CVehicle* pVehicle, CVector const& posn, bool unused, bool bIsBoat);
static void JoinCarWithRoadAccordingToMission(CVehicle* pVehicle);
```
```cpp
// CCarCtrl::JoinCarWithRoadSystem(veh);
```
## 移除与兴趣车
```cpp
static void PossiblyRemoveVehicle(CVehicle* pVehicle);
static void RemoveDistantCars();
static void RemoveCarsIfThePoolGetsFull();
static void RegisterVehicleOfInterest(CVehicle* pVehicle);
static void RemoveFromInterestingVehicleList(CVehicle* pVehicle);
```
```cpp
// 池满时游戏会清远车；任务车要保护好标志
```
## 上下乘客
```cpp
static void SetUpDriverAndPassengersForVehicle(CVehicle* pVehicle, int arg2, int arg3, bool arg4, bool arg5, int passengersNum);
```
```cpp
// 随机交通填充驾驶员/乘客
```
