UE4之PhysX物理基础
UE4默认会创建简单碰撞和复杂碰撞两种形态，然后基于用户需要进行Query（简单查询 vs 复杂查询）， PhysX会使用相应形态来进行碰撞检测（Collision Detection）。
常见的物理查询有三种：Raycast（零大小的射线检测，即有向线段）、Sweep（非零大小的检测，即扫掠体）和Overlap（空间相交检测）。根据设置的Response，来决定是Ignore(忽略)、Overlap(发出重叠事件)、还是Block(阻挡物体，并发出阻挡事件)。
也可以在PhysX上进行各种复杂的物理模拟（开启Simulate），如重力，刚体碰撞、软体变形、流体运动等，然后取回结果，更新场景物件的Transform，来为游戏提供丰富的物理表现。
在PhysX中，物理查询与物理模拟是两套完全独立的体系。
碰撞体
简单碰撞
简单碰撞的几何体类型有：盒体（Box）、 球体（Sphere）、凸包（Convex Meshe）和胶囊体（Capsule）。
AABB：Axis-Aligned Bounding Boxes（轴向包围盒）
OBB：Oriented Bounding Boxes（有向包围盒）
k-DOP：Discrete Oriented Polytope（离散有向多面体）
Convex Hull：凸壳
Aggregate Geometry：聚合几何体，多个各类简单碰撞几何体的集合
简单碰撞游戏中常用于：
① 角色（胶囊体）移动过程的碰撞检测
② 榴弹枪、手雷等投掷物的碰撞检测
③ 用于物理模拟
复杂碰撞
复杂碰撞是模型的三角网格体（Triangle Mesh）或地形高度图（Height Field）。
复杂碰撞游戏中常用于：
① 子弹的碰撞检测
② 刀等近战武器碰撞检测

使用简单碰撞和复杂碰撞
/** UnrealEngine\Engine\Source\Runtime\PhysicsCore\Public\BodySetupEnums.h **/ UENUM(BlueprintType) enum ECollisionTraceFlag { /** Use project physics settings (DefaultShapeComplexity) */ CTF_UseDefault UMETA(DisplayName="Project Default"), // 使用Project Setting里面的设置 /** Create both simple and complex shapes. Simple shapes are used for regular scene queries and collision tests. Complex shape (per poly) is used for complex scene queries.*/ CTF_UseSimpleAndComplex UMETA(DisplayName = "Simple And Complex"), // 同时使用简单碰撞和复杂碰撞 /** Create only simple shapes.

详细说明如下：
|
设置 |
描述 |
|---|---|
|
Project Default |
CTF_UseDefault 物件的Collision Complexity设置为Project Default时，将使用Project Settings中的Default Shape Complexity。 注：若Project Settings的Default Shape Complexity也为Project Default，则同时创建简单碰撞和复杂碰撞，即Simple And Complex。 |
|
Simple And Complex |
CTF_UseSimpleAndComplex 同时创建简单碰撞和复杂碰撞。简单碰撞用于常规场景查询和碰撞检测，复杂（逐多边形）碰撞用于复杂场景查询。 |
|
Use Simple Collision As Complex |
CTF_UseSimpleAsComplex 使用简单碰撞作为复杂碰撞。 注1：当请求复杂查询，引擎仍将查询简单碰撞。 注2：PhysX引擎中只创建简单碰撞，这有助于节约内存。 注3：几何体的简单碰撞计算往往更简单，性能更好。 注4：复杂碰撞在cook时，不会打进包中。详见：BodySetup.cpp中的UBodySetup::GetCookInfo函数 |
|
Use Complex Collision As Simple |
CTF_UseComplexAsSimple 使用复杂碰撞作为简单碰撞。 注1：当请求简单查询，引擎仍将查询复杂碰撞。 注2：物体不能进行Simulate；但可与其他模拟（简单）物体进行碰撞检测。 注3：PhysX引擎中只创建复杂碰撞，这有助于节约内存。 注4：简单碰撞在cook时，不会打进包中。详见：BodySetup.cpp中的UBodySetup::GetCookInfo函数 |
StaticMesh的简单碰撞和复杂碰撞
在StaticMesh编辑器中，为模型生成和删除简单碰撞
选中简单碰撞后，还可以对其进行移动、缩放、旋转编辑
注：不需要简单碰撞和复杂碰撞时，可以将物体设置为NoCollision
通过在Section中去掉Enable Collision勾选，可以把该Section的复杂碰撞去掉
可以将某一级lod作为物体的复杂碰撞 注：缺省为lod0
SkeletalMesh的简单碰撞和复杂碰撞
胶囊体简单碰撞
用于被子弹击中判定的复杂碰撞体
注：Physics Asset由一系列简单形状（如球体、胶囊体、盒体等）组成的碰撞体集合，比较高效
Landscape的碰撞
当Landscape的Collision Mip Level和Simple Collision Mip Level设置成一样时，简单碰撞和复杂碰撞共用一套碰撞
碰撞可视化
光照（Lit）模式
showflag.collision 1
简单碰撞（Player Collision）模式
注：选择Player Collision
showflag.collisionPawn 1
注1：这种简单碰撞查看方式，读取的并非是物理碰撞数据，而是模型上的数据，只能大致能反映简单碰撞的情况
注2：在PhysX引擎中，简单碰撞的PxShape的Flags为：eSIMULATION_SHAPE | eSCENE_QUERY_SHAPE | eVISUALIZATION
复杂碰撞（Visibility Collision）模式
注：选择Visibility Collision
showflag.collisionVisibility 1
注1：这种复杂碰撞查看方式，读取的并非是物理碰撞数据，而是模型上的数据，只能大致能反映复杂碰撞的情况
注2：在PhysX引擎中，复杂碰撞的PxShape的Flags为：eSCENE_QUERY_SHAPE | eVISUALIZATION
相关代码说明
bool FStaticMeshSceneProxy::IsCollisionView(const FEngineShowFlags& EngineShowFlags, bool& bDrawSimpleCollision, bool& bDrawComplexCollision) const
FPrimitiveViewRelevance FStaticMeshSceneProxy::GetViewRelevance(const FSceneView* View) const
void FStaticMeshSceneProxy::GetDynamicMeshElements(const TArray<const FSceneView*>& Views, const FSceneViewFamily& ViewFamily, uint32 VisibilityMap, FMeshElementCollector& Collector) const
以上2个函数中会调用IsCollisionView函数，来获取是否绘制Simple碰撞和Complex碰撞。
PXVIS collision
光照（Lit）模式：
PXVIS collision结果如下：
PVD中查看
注：Box为简单碰撞，球体为复杂碰撞
注：选中物体使用的是简单碰撞，碰撞设置为Use Simple Collision As Complex
一个战车模型，简单碰撞由9个Box和4个ConvexMesh组成，复杂碰撞由1个TriangleMesh组成
模型在UE中如下：
同一个模型，在场景摆放两个实例。这两个实例的ConvexMesh和Material是共享的。 注：但PxShape、PxConvexMeshGeometry、PxTriangleMeshGeometry实例是分开的
模型在UE中如下：
创建PhysX Shape

两个物体之间的碰撞规则

#
|
物体B | |||
| Ignore | Overlap | Block | ||
| 物体A | Ignore | Ignore | Ignore | Ignore |
| Overlap | Ignore | Overlap | Overlap | |
| Block | Ignore | Overlap | Block | |
注1：物体勾选了Simulation Generates Hit Events（模拟生成命中事件），在发生Block时，自己才会收到命中事件，如：ReceiveHit 或 OnComponentHit。
注2：物体勾选了生成重叠事件（Generate Overlap Events），在发生Overlap时，自己才会收到重叠事件，如：ReceiveBeginOverlap 和 ReceiveEndOverlap
注3：发生了Overlap，但没勾选生成重叠事件（Generate Overlap Events），则效果与Ignore一样，物体得不到任何反馈。
碰撞Response设置说明
注1：球体的Object Type为PhysicsBody，墙壁的Object Type为WorldDynamic
注2：球体与WorldDynamic类型的物体之间会产生Block，墙壁与PhysicsBody类型的物体之间也会产生Block，根据上面的规则，球体和墙壁发生接触时会产生Block
示例1：碰撞时墙壁收到Hit Events
示例2：重叠时球体和墙壁都会收到Overlap Events
开启物理模拟（Simulate）
一旦开启物理模拟，则这个Actor的所有运动状态都交由物理世界全权控制，物体会受到相关很多力的影响，如重力、摩擦力、空气阻力。
StaticMesh开启Simulate
SketetalMesh开启Simulate
Landscape开启Simulate
Simulate时也产生Hit Event和Overlap Event
