`CPhysical.h` · 继承 `CEntity`
Ped / Vehicle / Object 的物理基类。逻辑帧改速度力；drawing 只读。
## 线速度与角速度
```cpp
CVector m_vecMoveSpeed;
CVector m_vecTurnSpeed;
```
```cpp
auto* ph = static_cast(veh);
ph->m_vecMoveSpeed = CVector(0.0f, 0.5f, 0.0f);
```
## 质量与阻力
```cpp
float m_fMass;
float m_fTurnMass;
float m_fAirResistance;
float m_fElasticity;
float m_fBuoyancyConstant;
```
```cpp
// 改质量影响碰撞，谨慎
```
## 施加力
```cpp
void ApplyMoveForce(CVector force);
void ApplyTurnForce(CVector dir, CVector velocity);
void ApplyForce(CVector dir, CVector velocity, bool bUpdateTurnSpeed);
void ApplyGravity();
```
```cpp
ph->ApplyMoveForce(CVector(0.0f, 0.0f, 0.1f));
```
## 附着实体
```cpp
void AttachEntityToEntity(CEntity* entity, CVector offset, CVector rotation);
void AttachEntityToEntity(CEntity* entity, CVector* offset, RtQuat* rotation);
void DettachEntityFromEntity(float x, float y, float z, bool useCollision);
CPhysical* m_pAttachedTo;
```
```cpp
// ph->AttachEntityToEntity(other, offset, rot);
// ph->DettachEntityFromEntity(0, 0, 0, true);
```
## 免疫标志
```cpp
bool bBulletProof : 1;
bool bFireProof : 1;
bool bCollisionProof : 1;
bool bMeleeProof : 1;
bool bExplosionProof : 1;
bool bInvulnerable : 1;
```
```cpp
ph->bBulletProof = true;
ph->bFireProof = true;
```
## 重力与碰撞开关
```cpp
bool bApplyGravity : 1;
bool bCollidable : 1;
bool bDisableMoveForce : 1;
bool bDontApplySpeed : 1;
```
```cpp
// ph->bApplyGravity = false; // 飘
```
## 相对放置
```cpp
static void PlacePhysicalRelativeToOtherPhysical(
CPhysical* physical1, CPhysical* physical2, CVector offset);
```
```cpp
// CPhysical::PlacePhysicalRelativeToOtherPhysical(a, b, offset);
```
