在这三个容器中你会首选使用的就是UE4中的TArray,它就跟std::vector类一样,但是提供了更多了函数,下面是一些常见的操作: TArray<AActor*> ActorArray =GetActorArrayFromSomewhere();// Tells how many elements (AActors) are currently stored in ActorArray.int32 ArraySize = ActorArray.Num();// TArr...
ReplicatedMovement.Rotation = RootComponent->GetComponentRotation(); ReplicatedMovement.LinearVelocity =GetVelocity(); ReplicatedMovement.AngularVelocity = FVector::ZeroVector;// Technically, the values might have stayed the same, but we'll just assume they've changed.bWasRepMovementModified =true; } b...

Spline添加Rotation。前后点位世界坐标相减。我这里需要保持Y轴Z轴不变,只改变了X轴;也可以使用Rotation From X Vector,表示实现目标角度所需要的旋转,输入值为目标角度,输出一个旋转。 向量最好都做一下Normalize。 使用Get Transformat Distance Along Spline来设置运动物体位置和角度...
⑤-④计算动画起始差距,差距在动画开始到目标地点之间,可以从上面蓝色箭头看到,这一步是反解上面Vector到Rotation的逻辑,所以这个Vector就是归一化的蓝色向量指示方向,而这个Starting Offset就是为了让角色不在平面方向上进入墙体所设置的宽度,可以手动将中间的点乘Starting Offset Y值改为130或者更高,测试一下就明白了...
需要注意的是,UpdateRotation方法在PlayerController类中每帧都会调用一次。我考虑了GetActorTimeDilation()函数,因此当使用slomo方法时,相机转动的速度不会变动。 2. 在Character中的相机控制 我的Character类中有一个PreUpdateCamera()函数,该函数如下: voidAExedreCharacter::PreUpdateCamera(floatDeltaTime ) ...

使用CBL新建一个Get Rotation XVector节点,将其连接到Get World Rotation节点的输出引脚,如图77所示。 现在,我们获得了摄像机X轴的朝向信息。从技术角度来讲,因为还没有连接到事件的主要链条上,所以此刻还不能工作,但是理论上,一旦与事件的主要链条连接上,我们就可以获得摄像机的信息。目前这些只是摄像机跟随玩家这个...
