Unreal Engine C++ Fundamentals – UAnimInstance
Hey guys,
Yet again we are going to dive into Unreal Engine C++ Fundamentals by exploring UAnimInstance aka Animation Instance.
The project for this tutorial is available on GitHub as always.
What is a Anim Instance ?
An Anim Instance is the animation instance that drives our class.
Great ! So what is an Anim Instance ?
It’s really just a container and / or facade object that interacts with our class and any animations / montages that this class is currently executing.
What it allows us to do, is have fine grain control over the state and playback of our animations.
That’s great for you but what about my needs ?
Well since the UAnimInstance object lets you take control of your animations it will be beneficial to a lot of game play mechanics.
Let’s just quickly glance over some of the parts of the Anim Instance to see how they could help by examining the PlayAnimMontage call.
float ACharacter::PlayAnimMontage(class UAnimMontage* AnimMontage, float InPlayRate, FName StartSectionName) { UAnimInstance * AnimInstance = (Mesh)? Mesh->GetAnimInstance() : nullptr; if( AnimMontage && AnimInstance ) { float const Duration = AnimInstance->Montage_Play(AnimMontage, InPlayRate); if (Duration > 0.f) { // Start at a given Section. if( StartSectionName != NAME_None ) { AnimInstance->Montage_JumpToSection(StartSectionName, AnimMontage); } return Duration; } } return 0.f; }
As you guys can see, the guys at Epic have taken a bunch of pieces of the Anim Instance class and wrapped them in a helper method.
So what is this method doing ?
Well it brings in the AnimInstance from our Mesh object by calling GetAnimInstance().
Then it validates that the montage we want to interact with is available and the Anim Instance is not null.
If that passes it then kicks off the Montage_Play method right on the Anim Instance by passing in the montage and the Play Rate.
So far so good.
We then look at a few more conditionals that just ensure the data that is required is available to us.
And then lastly it calls Montage_JumpToSection as the overall method takes in a StartSectionName value that determines the playback position.
Even Epic likes Anim Instances ? How do I subscribe to their newsletter ?
Well you can do that through their web site or simply by getting a reference to your local neighborhood Anim Instance and start performing some of these operations.
What are these common operations ?
There are a bunch of them but let’s go over the immediately meaningful ones.
Montage_Stop – stops the montage and blends in the next animation using the blend speed parameter. Good for killing montages mid playback.
// takes in a blend speed ( 1.0f ) as well as the montage AnimInstance->Montage_Stop(1.0f, AttackMontage->Montage);
Montage_Pause – pauses the current animation and freezes parts of the object tied to those animations. In our case we are able to pause a punch mid stream. Great for effects where you need to halt an animation, do some other activities and then resume.
// takes in the montage you want to pause AnimInstance->Montage_Pause(AttackMontage->Montage);
Montage_Resume – called after you call Montage_Pause as it will resume the playback of the animation from that point in time.
// takes in the montage you want to resume playback for AnimInstance->Montage_Resume(AttackMontage->Montage);
Montage_Play – triggers the playback of an animation based on various criteria like montage, speed, return type, playback start position and a control variable to stop other montages if they are currently executing.
// kicks off the playback at a steady rate of 1 and starts playback at 0 frames AnimInstance->Montage_Play(AttackMontage->Montage, 1.0f, EMontagePlayReturnType::Duration, 0.0f, true);
Montage_GetPosition – returns the current position of the playback frames as they are contained within the duration of the animation.
// returns current playback position float CurrentPosition = AnimInstance->Montage_GetPosition(AttackMontage->Montage)
Montage_IsPlaying – returns a boolean to let the caller know if we have an active animation.
// checks to see if any animations in a montage are active AnimInstance->Montage_IsPlaying
Montage_JumpToSectionUAnimInstance – moves the animation starting point to the location of the section as it’s setup in the Animation Montage.
// starts the animation at a specific section AnimInstance->Montage_JumpToSection(StartSectionName, AnimMontage);
Pretty neat eh !
As you can see, we get a lot freedom with access to anim instances as well as the ability to control our animations easily.
Animation Blueprint, Implement Custom C++ Logic Via Tick Updates
Overview
Dear Community,
Extending AnimInstance is a wonderful way to create all sorts of custom animation systems and also efficiently utilize the existing UE4 anim blueprint functions.
It’s very useful to know how you can do certain actions when the Anim Instance for a Character is first created, and how to do actions every tick while the anim instance exists!
Below are the two Anim Instance functions that are similar to PostInitializeComponents and Tick(DeltaTime) for Actors
virtual void NativeInitializeAnimation ( ) OVERRIDE ; virtual void NativeUpdateAnimation ( float DeltaTimeX ) OVERRIDE ;
Example: An Anim-BP-Accessible Variable: IsMoving
Here is a complete example that obtains the Owning Pawn in the Init function (to avoid reobtaining the reference every tick).
Then, every tick / moment of the anim instance’s existance, the boolean variable IsMoving is updated to reflect the velocity of the Owning pawn.
IsMoving can now be obtained from within the Anim Blueprint because of its UPROPERTY settings, and used in your animation blueprint logic.
Enjoy!
.h
/* By Rama */ # pragma once # include “VictoryAnimInstance.generated.h” UCLASS ( transient , Blueprintable , hideCategories = AnimInstance , BlueprintType ) class UVictoryAnimInstance : public UAnimInstance { GENERATED_BODY ( ) public : /** Is Moving */ UPROPERTY ( EditAnywhere , BlueprintReadWrite , Category = Movement ) bool IsMoving ; //init and tick public : APawn * OwningPawn ; virtual void NativeInitializeAnimation ( ) override ; virtual void NativeUpdateAnimation ( float DeltaTimeX ) override ; } ;
.cpp
# include “VictoryGame.h” # include “VictoryAnimInstance.h” ////////////////////////////////////////////////////////////////////////// // UVictoryAnimInstance //This function is like PostInitAnimtree in UE3 void UVictoryAnimInstance :: NativeInitializeAnimation ( ) { //Very Important Line Super :: NativeInitializeAnimation ( ) ; //Cache the owning pawn for use in Tick OwningPawn = TryGetPawnOwner ( ) ; } //Tick void UVictoryAnimInstance :: NativeUpdateAnimation ( float DeltaTimeX ) { //Very Important Line Super :: NativeUpdateAnimation ( DeltaTimeX ) ; //Always Check Pointers if ( ! OwningPawn ) { return ; } //Set whether moving or not IsMoving = ( OwningPawn -> GetVelocity ( ) . SizeSquared ( ) > 25 ) ; }
Final Step: Reparenting your Character’s Anim Blueprint
You need to make sure your Character is using your extended version of AnimInstance 🙂
For more information on reparenting Anim BPs, and making custom Animation Blueprint classes, see this code sample:
Animation Blueprints, Custom C++ Variables
Conclusion
Now you know what functions to override to create complicated Anim Blueprint logic with assistance from the C++ code,
or run your anim instance mostly from the C++ code (especially the event graph part)!
Enjoy!
