1 在AuraPlayerController.h中
增加
public:
virtual void PlayerTick(float DeltaTime) override;
private:
CursorTrace();
2 在AuraPlayerController.cpp中实现 PlayerTick，CursorTrace
PlayerTick（）
{
CursorTrace();
}
CursorTrace()
{
FHitResult CursorHit;
GetHitResultUnderCursor(ECC_Visibility,false ,CursorHit);
if(!CursorHit.bBlockingHit) return;
LastActor = ThisActor;
ThisActor = Cast<IEnemyInterface>(CursorHit.GetActor());
if(LastActor == nullptr)
{
if(ThisActor!=nullptr)
{
ThisActor->HighlightActor();
}
else
{
}
}
else
{
if(ThisActor == nullptr)
{
LastActor->UnHighlightActor();
}
else
{
if(LastActor != ThisActor)
{
LastActor->UnHighlightActor();
ThisActor->HighlightActor();
}
else
{
}
}
}
}
3 在AuraPlayerController.h中
privat:
IEnemyInterface* LastActor;
IEnemyInterface* ThisActor;
4 在AAuraEnemy.h中
public:
bool bHighlighted = false;
5 在 AAuraEnemy.cpp中
在HighlightActor()中bHighlighted =true;
在UnHighlightActor()中bHighlighted =false;
