How to create custom AbilityTasks

The set up for AbilityTasks is mostly same as Gameplay Tasks

• Create static “factory” function
• Override Activate

UKotAbilityTask_WaitForOverlap* UKotAbilityTask_WaitForOverlap::KotWaitForOverlap(UGameplayAbility* OwningAbility)
{
	auto* Task = NewAbilityTask<UKotAbilityTask_WaitForOverlap>(OwningAbility);
	return Task;
}
 
void UKotAbilityTask_WaitForOverlap::Activate()
{
	SetWaitingOnAvatar();
 
	if (UPrimitiveComponent* PrimComponent = GetComponent())
	{
		PrimComponent->OnComponentBeginOverlap.AddDynamic(this, &ThisClass::BeginOverlap);
	}
}
 
//etc.

Handling delegates §

• If you bind any Delegates in the ability task you can override OnDestroy for cleaning them up.
• Before you broadcast any delegates from the ability task, check ShouldBroadcastAbilityTaskDelegates()
