`CRadar.h`
Blip 句柄跨帧要自己存；清标用 `ClearBlip`。
## 坐标 Blip
```cpp
static int SetCoordBlip(eBlipType type, CVector posn, unsigned int arg2, eBlipDisplay blipDisplay, char* scriptName);
static int SetShortRangeCoordBlip(eBlipType type, CVector posn, unsigned int arg2, eBlipDisplay blipDisplay, char* scriptName);
```
```cpp
int blip = CRadar::SetCoordBlip(BLIP_COORD, pos, 0, BLIP_DISPLAY_BOTH, nullptr);
```
## 实体 Blip
```cpp
static int SetEntityBlip(eBlipType type, int entityHandle, unsigned int arg2, eBlipDisplay blipDisplay);
static void ClearBlipForEntity(eBlipType blipType, int entityHandle);
```
```cpp
// int handle = CPools::GetPedRef(ped);
// int blip = CRadar::SetEntityBlip(BLIP_CHAR, handle, 0, BLIP_DISPLAY_BOTH);
```
## 改 Blip 外观
```cpp
static void ChangeBlipColour(int blipIndex, unsigned int color);
static void ChangeBlipScale(int blipIndex, int size);
static void ChangeBlipDisplay(int blipIndex, eBlipDisplay blipDisplay);
static void SetBlipSprite(int blipIndex, int spriteId);
static void SetBlipFriendly(int blipIndex, unsigned char friendly);
```
```cpp
CRadar::ChangeBlipColour(blip, BLIP_COLOUR_YELLOW);
CRadar::SetBlipSprite(blip, RADAR_SPRITE_WAYPOINT); // 以枚举为准
```
## 清除 Blip
```cpp
static void ClearBlip(int blipIndex);
static void ClearActualBlip(int blipArrId);
```
```cpp
CRadar::ClearBlip(blip);
```
## 雷达画区域
绘制帧 / 雷达钩子里用。
```cpp
static void DrawAreaOnRadar(CRect const& rect, CRGBA const& color, bool inMenu);
```
```cpp
// CRadar::DrawAreaOnRadar(rect, color, false);
```
## 常用枚举
见 `CRadar.h`。
```cpp
// BLIP_COORD, BLIP_CHAR, BLIP_CAR, BLIP_OBJECT, BLIP_PICKUP ...
// BLIP_DISPLAY_BOTH, BLIP_DISPLAY_BLIP_ONLY ...
```
