【UE5】CPP中使用ControlRig蓝图节点示例

基本流程

逻辑代码迁移到C++自定义ControlRig节点：

需要.Build中添加编译要用到的模块AnimationCore

RigUnit_ProceduralCharacter.h

#pragma region 计算脚部的目标朝向//计算脚部的目标朝向USTRUCT(meta = (DisplayName = "GetFootTargetAngle"))struct PROCEDURALANIM_API FRigUnit_GetFootTargetAngle : public FRigUnit{GENERATED_BODY()RIGVM_METHOD()virtual void Execute() override;UPROPERTY(meta = (Input))FVector RigSpaceVelocity;UPROPERTY(meta = (Output))float FootTargetZAngle;};FVector EulerFromQuat(const FQuat& Rotation, EEulerRotationOrder RotationOrder = EEulerRotationOrder::ZYX, bool bUseUEHandyness = false);FQuat FromTwoVectors(const FVector& A, const FVector& B);#pragma endregion

RigUnit_ProceduralCharacter.cpp

#pragma region 计算脚部的目标朝向FRigUnit_GetFootTargetAngle_Execute(){const float OriginalZAngle = AnimationCore::EulerFromQuat(FromTwoVectors(FVector(0,1,0),RigSpaceVelocity)).Z;if (OriginalZAngle > 100){FootTargetZAngle = OriginalZAngle - 180;}else if (OriginalZAngle < -100){FootTargetZAngle = OriginalZAngle + 180;}else{FootTargetZAngle = OriginalZAngle;}}FQuat FromTwoVectors(const FVector& A, const FVector& B){if (A.IsNearlyZero() || B.IsNearlyZero()){return FQuat::Identity;}return FRigVMMathLibrary::FindQuatBetweenVectors(A, B);}
#pragma endregion

对于一些蓝图和实际C++API名字不一致的节点

搜DisplayName="蓝图节点名"找对应的C++API

比如：Interpolate节点
