Ability Types #

First, we'll cover the different types of abilities to give you a clear understanding of their foundational structure and how they work.

Abilities are categorized into two main types: Active Abilities and Passive Abilities.

Active Abilities require the player to actively use them by performing an action during gameplay.

Passive Abilities are always active, constantly “listening” for specific conditions or actions to trigger their effects without any direct input from the player.

Both Passive and Active Abilities are dervied from the same base class: BP_Ability_Base

Active Abilities
Active abilities are all derived from a common base class, ActiveAbilityBase, which provides the foundational functionality for all active abilities. There are five types of active abilities that build upon this base:

• BP_ActiveAbilityBase (default for generic abilities).
• BP_Ability_Projectile_Base (for abilities that fire projectiles).
• BP_Ability_Beam_Base (for abilities using continuous beams).
• BP_Ability_AOE_Base (for area-of-effect abilities).
• BP_Ability_Summon_Base (for summoning entities).

Passive Abilities
Passive abilities are all derived from a shared base class as well, BP_PassiveAbilityBase, which provides the core structure for passive mechanics. There are five specialized types of passive abilities:

• BP_PassiveAbility_ConstantAttribute (Always active, applying constant attribute effects).
• BP_PassiveAbility_OnEquipment (Activates conditionally based on specific equipment being used).
• BP_PassiveAbility_OnGettingHit (Triggers when the player is hit).
• BP_PassiveAbility_OnHit (Activates when the player lands a hit).
• BP_PassiveAbility_OnKil (Triggers upon killing an enemy).

Each of these types can be configured with multiple conditions, allowing for flexible behaviors based on gameplay scenarios.

Active ability Base
We use Active Ability Base for generic abilities. Generic abilities can:

• Apply Impact (Damage, Healing, Attributes, Buffs and Knockback.
• Spawn area-of-effects (AOE)
• Spawn Niagara effects
• Use a mesh for visual representation
• Play sound effects.
• Apply Screen Shake

Projectile Base
Projectile Base is used for abilities that shoot projectiles from the player. In addition to the basic features of Active Ability Base, it offers:

• Launching the projectile at a specified speed.
• Targets can be automatically tracked and followed.
• The projectile can pass through multiple targets.
• The projectile can be affected by gravity.
• The projectile has a specified collision
• The projectile can expire after a set duration.

Beam Base
Beam Base is designed for continuous abilities, such as lasers, that remain active while held and end upon release. These abilities apply their effects while being attached to the player and can target one or multiple enemies within a set range. In addition to the core features of Active Ability Base, it provides:

• Performs a box trace from the player in the direction of the camera to detect targets within range.
• Applies impact effects to one or multiple enemies detected by the box trace
• Plays Niagara effects and sound for the beam.

AOE Base
AOE Base is used for area-of-effect abilities, which can be spawned directly or from another ability. These abilities can:

• Find targets through a sphere, box, or cone.
• Apply Impact to multiple targets
• Have a lifetime that defines how long the effect lasts.
• Apply Impact at set intervals if a lifetime is set.
• Spawn decals for visual markers in the affected area.

Custom Abilities
Some abilities fall outside the scope of these generic functionalities. For such cases, you can create a custom ability. A custom ability should be a direct or indirect child of Active Ability Base. To implement its functionality, override the 'Apply Ability Effect' function and define the custom behavior within it.

Creating an Active Ability #

Let's create an ability together to better understand the process. We'll go step by step, starting with defining the type of ability and setting up its functionality. Let's make something simple yet practical: a Power Strike that deals damage to enemies in front of you.

Start by adding a new row to DT_ActiveAbilities and assigning it a name, description, and icon under the generic attributes. Set its ability type to Offensive. This ensures the icon displays with the correct background color. Since this is an AOE Ability, we want the Ability to Active be an BP_Ability_AOE_Base. Finally, assign an ability tag to identify it. For this example, add a new tag: 'Ability.Active.Power Strike'.

We want this ability to function as an AOE directional Ability that spawns on the player. To achieve this, adjust the Targeting Attributes. Set the targeting type to 'Attach to Self' and the trace type to 'Directional Based'. Since the ability should only affect enemies, assign the 'Affect These Targets' attribute the tag 'Target.Enemy'.

Let's add cooldowns to the ability. Set the cooldown to 8 seconds and the maximum charges to 2. You can configure these settings in the Cooldown Attributes.

Now let's set up the casting for this ability. Since we want a striking animation to play before the impact, enable casting. Go to the Casting Attributes and tick Uses Casting. Then, under Generic, we need the Cast Type Auto Release so the ability automatically activates after the animation. Typically, when using charges, it's common to skip attribute costs. Note that we do not have to change anything under Generic.

Since we have a singular animation, this ability only requires one animation stage, so we'll focus on configuring the Release Stage. This stage also ensures that cooldowns and costs are applied. Tick Uses This Cast Stage under Release Cast. For Root Motion Montage, select Anim_PowerStrike_RootMotion_Montage. For the In Motion Montage, select Anim_PowerStrike_UpperBody_Montage.

We need particles to play in the animation. Select the NS_Power_Strike_Adjusted as Niagara System on Notify. Since the Niagara effect has an incorrect angle and spawns inside the player, adjust the offsets to fix it.

If you'd like a sound effect to trigger, you can configure one under Sound Effect On Notify.

Next, open the Animation Montage to configure when the ability should spawn, trigger and when the Niagara should spawn. At the frame where the hit lands, add a new Montage Notify. Right-click on the first track at the desired frame, select Add Notify, and name it Attach. This marks the moment the ability spawns. For AOE abilities, we don't need an 'Apply Effect' Notify. The ability will do this. Directly after the first notify, add a second one and name it: 'Niagara'

For the AoE attributes, start by triggering 'Uses AoE Effect.' Exclude the player from the effect. Use a box trace for this ability, as box traces are used for abilities where we want to trace in front of the player rather than around them (Note that this only works with a Directional Based Trace Type in Targetting Attributes) . In box extents, define the width, depth, and height. Set the ability's lifetime to 1 second to allow the Niagara effect to complete. Do not assign an interval, as we only want the effect to trigger once. A decal is not needed.

The ability has no impact yet. Let's create it. Go to the Impact Attributes and open AOE Attributes. Now let's start with the Damage Attributes. Enable Does Damage to make the ability deal damage. For now, leave the remaining settings at their default values.

---

Creating Buffs #

Buffs
Buffs are effects with a duration that can grant the owner attributes or deal damage. Like active abilities, you can implement custom logic if needed. By default, we provide the standard functionality a buff can offer. Keep in mind that buffs can also have negative effects, functioning as debuffs.

Buffs are defined in the DT_Buffs datatable. Here, you can configure their appearance, effects, stacking behavior, application interval, and associated Niagara effects. Note that the buff's lifetime is not configured in this datatable–it is set in the ability that applies the buff.

When an ability applies a buff, you can hover over the ability to see the buffs it applies. Additionally, hovering over a buff will display its description.

You may want an ability to activate a buff upon impact. In this context, buffs include both positive effects (like increased stats or damage) and negative effects (such as reduced stats or debuffs). These buffs need to be created in the DT_Buffs datatable.

Let's create a buff and add it to one of the existing preview abilities, Blazing Speed. We will name the buff the same as the ability, so it's easy to identify that this buff comes from Blazing Speed.

Buffs share the same Generic Attributes struct as Active Abilities but require a different Ability to Activate: BP_Ability_Buff_Base. Set the Ability Type to Buff so the player can easily identify it as a buff. Assign a tag of type Ability.Buff and use the same icon as the ability to visually connect the buff to the ability.

Buffs also share the same Impact Attributes as abilities. For this buff, we want to add movement speed to the player as long as it remains active. In Attributes to Give to Target, add a Persistent Attribute, since movement speed is a persistent effect. Click on the + icon under Attributes and select the tag: Attribute.Persistent.Character Movement Speed. Set a value under Added to display the added value of the buff in the UI.

In the Buff Attributes, we apply settings specific to how the buff behaves. For this buff, we don't want it to stack, as stacking would double its effect. Additionally, we don't want this bonus to apply at intervals. We do want a Niagara effect to display the blazing speed, so select NS_Fire_Trail. This effect doesn't require a socket or an offset.

Adding buff to ability: go to ability’s impact attributes.

Creating Passive Abilities

Sometimes, we want an effect to trigger based on certain conditions without having to activate an ability. These are called passive abilities. We don’t equip them, as they are always listening for specific events. Since these events are very generic, we’ve created the most common ones.

A passive ability can activate by:

• Constantly (e.g., increasing strength by 5% at all times).
• Equipping certain equipment.
• On Getting Hit.
• On Doing Hit.
• On Kill.

When creating a passive ability, first determine if it can be achieved using the generic implementations provided. If not, you can either inherit from one of the triggers we’ve implemented or create a custom trigger.

If you inherit from BP_PassiveAbility_OnGettingHit, BP_PassiveAbility_OnHit, or BP_PassiveAbility_OnKill, you can override the Apply Custom Effect on Target and Apply Custom Effect on Owner functions. These are automatically called when the trigger activates.

For custom triggers, ensure the ability has a trigger type of 'Other Conditional Modifier.' This prevents effects from being applied to unrelated modifiers.

Let's create a passive ability. When the player gets hit, this ability will grant a regeneration buff. To balance the effect, we’ll add a cooldown to the ability.

Since passive abilities share the same Generic Attributes, we now know how to configure them. It's important to note that the Ability to Spawn should be set to the Passive Ability Type. In this case, it will be BP_PassiveAbility_OnGettingHit. Additionally, we need to set the Trigger Type to On Getting Hit for this ability.

To prevent spamming and stacking the buff on getting hit, we need to add a cooldown to this ability.

For the application, we don't want the effect to affect other targets. We won't directly apply attributes or damage, but we do want to apply a buff. Lastly, we don't need a Niagara effect for this trigger, as the buff will apply its own effect.

We want to configure the On Getting Hit requirements. In this section, tick Always Apply on Getting Hit. This will ensure the ability always attempts to apply the effect, although the cooldown will prevent it from applying constantly.
