news 2025/6/29 12:26:01

1.创建一个GA，用于设置角色的受击

创建蒙太奇，设置插槽

然后进入GA_Enemy_MeleeAttack，敌人的攻击。当enemy攻击命中player后，将发送对应tag激活ga。

然后打开DA_PlayerStartUpAbilities

2.玩家受击时的反应

先打开玩家的骨骼

3。打开XMBWarriorFunctionLibrary.h

//player受到打击时，确定打击的方向从而确定受击蒙太奇UFUNCTION(BlueprintPure, Category = "XMBWorrior|FunctionLibrary")static FGameplayTag ComputeHitReactDirectionTag(AActor* InAttacker, AActor* InVictim, float& OutAngleDifference);


FGameplayTag UXMBWarriorFunctionLibrary::ComputeHitReactDirectionTag(AActor* InAttacker, AActor* InVictim,float& OutAngleDifference)
{check(InAttacker && InVictim);const FVector VictimForward = InVictim->GetActorForwardVector();const FVector VictimToAttackerNormalized = (InAttacker->GetActorLocation() - InVictim->GetActorLocation()).GetSafeNormal();const float DotResult = FVector::DotProduct(VictimForward, VictimToAttackerNormalized);OutAngleDifference = UKismetMathLibrary::DegAcos(DotResult);const FVector CrossResult = FVector::CrossProduct(VictimForward, VictimToAttackerNormalized);if (CrossResult.Z < 0.f){OutAngleDifference *= -1.f;}if (OutAngleDifference >= -45.f && OutAngleDifference <= 45.f){return XMBGameplayTags::Shared_Status_HitReact_Front;}else if (OutAngleDifference < -45.f && OutAngleDifference >= -135.f){return XMBGameplayTags::Shared_Status_HitReact_Left;}else if (OutAngleDifference < -135.f || OutAngleDifference > 135.f){return XMBGameplayTags::Shared_Status_HitReact_Back;}else if (OutAngleDifference > 45.f && OutAngleDifference <= 135.f){return XMBGameplayTags::Shared_Status_HitReact_Right;}return XMBGameplayTags::Shared_Status_HitReact_Front;}

创建四个方向的tag
