GetMesh() is undefined?

Development Programming & Scripting C++

Hello! GetMesh() is not working for me and I do not understand why.

I included #include “GameFramework/Character.h”

Code Follows… should be straight forward



EBTNodeResult::Type UBTT_MeleeAttack::ExecuteTask(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory)
{
Super::ExecuteTask(OwnerComp, NodeMemory);

//Play attack Animation
UAnimInstance* AnimInstance = GetMesh()->GetAnimInstance();

return EBTNodeResult::Succeeded;
}

Is it because I am trying to call in in a Behavior Tree Task Node or something?

Wow this is driving me crazy. Here is how it works…

UAnimInstance* AnimInstance = OwnerComp.GetAIOwner()->GetCharacter()->GetMesh()->GetAnimInstance();

Does anybody have tutorial or can explain a way to play an animation from a behavior tree task node in C++?

Hi,

You really should have to. Here the code I use:



if (UseAnim)
{
      MyPawn->PlayAnimMontage(UseAnim);
}

MyPawn is an


ACharacter*

UseAnim is an


UAnimMontage

This is the implementation for PlayAnimMontage (its a function I made)



float AMyCharacter::PlayAnimMontage(class UAnimMontage* AnimMontage, float InPlayRate, FName StartSectionName)
{
    USkeletalMeshComponent* UseMesh = GetPawnMesh();
    if (AnimMontage && UseMesh && UseMesh->AnimScriptInstance)
    {
        float time = 0.0f;
        return UseMesh->AnimScriptInstance->Montage_Play(AnimMontage, InPlayRate);
    }
    return 0.0f;
}
