 这一节对PawnMovementComponent进行编辑，确定响应。

首先打开PawnMovementComponent.h添加如下代码：

public:

virtual void TickComponent(float DeltaTime, enum ELevelTick TickType, FActorComponentTickFunction *ThisTickFunction) override;
 

在PawnMovementComponent.cpp中定义它：

//Make sure that everything is still valid, and that we are allowed to move.

if (!PawnOwner || !UpdatedComponent || ShouldSkipUpdate(DeltaTime))

{

return;

}//

//Get (and then clear) the movement vector that we set in ACollidingPawn::Tick

FVector DesiredMovementThisFrame = ConsumeInputVector().GetClampedToMaxSize(1.0f) * DeltaTime * 150.0f;

if (!DesiredMovementThisFrame.IsNearlyZero())

{

FHitResult Hit;

SafeMoveUpdatedComponent(DesiredMovementThisFrame, UpdatedComponent->GetComponentRotation(), true, Hit);

//If we bumped into something, try to slide along it

if (Hit.IsValidBlockingHit())

{

SlideAlongSurface(DesiredMovementThisFrame, 1.f - Hit.Time,Hit.Normal,Hit);

}

}


 

ConsumeInputVector()，获取移动向量
SafeMoveUpdatedComponent，处理移动
SlideAlongSurface，处理阻挡
