Normalize(); float BowAngleInDeg = FMath::RadiansToDegrees( FGenericPlatformMath::Acos(FVector::DotProduct(TargetShip-> GetActorForwardVector(), LineSight))); if (FVector::DotProduct(TargetShip-> GetActorRightVector(), LineSight) < 0. Okay so this is probably a really simple question but I'll leave it open ended so people can provide helpers for others, I'll take these and put them on the wiki in an easy to find document as searching for Math, FMath, Vector, Max etc are not the best of search terms across the board for the engine or websites. – FPlatformMath is a typedef to a platform-specific class. 可以看到这个结构体基本上是实现的C++的 GenericPlatformMath. ===== GenericPlatformMath. 这里用到的Sin函数在strcut FGenericPlatformMath UE4 では多くの数学的な実装は FMath 型に static メンバー関数として実装されている。 FGenericPlatformMath 関数 効果 UE4; int32値 n を与え [0.
