Fair Warning: This is a C++ plugin for UE5

Plugin for some common things I often find myself needing when working with the GameplayAbility plugin. It's broken up into modules so that you can pick and choose what you need.

Much of this is a mash-up of tranek's fantastic GASShooter and GASDocumentation, along with some parts from Epic's Valley of the Ancients demo, and the sample project ActionRPG.

The intent is to move a lot of common/useful functionality into a project agnostic plugin that can be re-used. I try to expose functionality to blueprints, but it's expected that a dev will be using both C++ and blueprints.

Documentation is poor. I'm working on it.

Core functionality for the plugin. UAxAbilitySystemComponent and UAxGameplayAbility make up the bulk of this module, but there's also some helpers for attributes, animations, debugging, AI and the EnhancedInput.

A set of replacement actors for pawns, characters, game modes, player states, ai and player controllers that support the ModularGameplay features added in UE5, and are also set up out of the box for working with gameplay abilities.

The controller and pawn actors register themselves with the UGameFrameworkComponentManager so they can be used with ModularGameplay.

For players, the ability system component exists on the AModularPlayerState, and for AI it's on AModularAIController. The pawns, AModularPawn and AModularCharacter, pick these up from either the controller or the player state and re-expose them for ease of use.

Pawns also have a startup ability set that is automatically applied when they receive their ability system.

These are still very much in flux, and I don't really recommend using them. I move code from my main project into these if I can abstract them away from the game sufficiently, but they're very volatile.

still working on updating this list ;)

Animation notify for sending a gameplay event to the owning actor.

When prototyping, I have a GameplayAbility that forwards the event to the actor's blueprint for easy testing. In my actual game, I use this for things like equip/unequip.

A data asset that is collection of GameplayAbilities and effects that can easily be given to a character. Make sure you choose AxGameplayAbilitySet and not GameplayAbilitySet.

I often use these to grant collections of abilities on character startup or when equipping a weapon, but they can also be used to apply multiple effects from a GameplayAbility. GameplayTags can be granted to a character this way as well through the use of a startup GameplayEffect that grants the tags.

/** Called by ::PossessedBy(...) or ::OnRep_Controller() */
void APrototypeCharacter::AddStartupGameplayAbilities()
{
	check(AbilitySystemComponent);

	if (GetLocalRole() == ROLE_Authority && StartupAbilitySet && !StartupAbilitySetHandles.Any())
	{
		StartupAbilitySet->Give(GetAbilitySystemComponent(), this, GetCharacterLevel(), StartupAbilitySetHandles);
	}
}
