`CPools.h`
跨帧存 **handle**，再用 `Get*` 取指针。池满会创建失败。
## 句柄转指针
脚本句柄 → 指针。无效 null。
```cpp
static CPed* GetPed(int handle);
static CVehicle* GetVehicle(int handle);
static CObject* GetObject(int handle);
```
```cpp
CPed* ped = CPools::GetPed(handle);
if (!ped) {
return;
}
```
## 指针转句柄
```cpp
static int GetPedRef(CPed* ped);
static int GetVehicleRef(CVehicle* vehicle);
static int GetObjectRef(CObject* object);
```
```cpp
int h = CPools::GetPedRef(ped);
CPed* p2 = CPools::GetPed(h);
```
## 主对象池
```cpp
static CPool& ms_pPedPool;
static CPool& ms_pVehiclePool;
static CPool& ms_pObjectPool;
static CPool& ms_pBuildingPool;
static CPool& ms_pDummyPool;
```
```cpp
#include "extensions/PoolIterator.h"
for (CVehicle* v : *CPools::ms_pVehiclePool) {
if (!v) {
continue;
}
}
```
## 任务与其它池
任务槽紧，别泄漏 Task。
```cpp
static CPool& ms_pTaskPool;
static CPool& ms_pPedIntelligencePool;
static CPool& ms_pColModelPool;
static CPool& ms_pPtrNodeSingleLinkPool;
static CPool& ms_pPtrNodeDoubleLinkPool;
```
```cpp
// 看占用：pool->GetNoOfUsedSpaces() 等，以 CPool 头文件为准
```
## 存档与槽位
一般只读；改存档流程要极谨慎。
```cpp
static bool Save();
static bool Load();
static bool SavePedPool();
static bool LoadPedPool();
// Vehicle / Object 同理
static void MakeSureSlotInObjectPoolIsEmpty(int slot);
```
```cpp
// 正常 ASI 不直接调 Save/Load
```
