Chain Hook

Pulls the player toward enemies.

Pressing the attack button again after connecting performs either a Punch or a Kick, depending on the distance to the target.

Punch slightly knocks enemies back.

Kick launches enemies into the air, causing them to take fall damage when they land.

Implementation

As you might expect, this is a multi-state skill with states such as Hook, Pull, Kick, and Punch.

When the Hook attack collides with an enemy, we use an Effect Pack to send the hook data to ourselves.

HookToActor — Effect Pack

Effect Pack: HookToActor

Linker Effect (BS): LinkHookGrapPositionToTargetPosition

Target Stat:ChainHook / Vector3 / HookGrapPosition

Processor:Linker

Apply Type:Temporary

Int Stat Effect (BS): IncreaseEvolutionNo_1

Target Stat:ChainHook / IntClamped / SkillEvolutionNo

Value:1

Int Stat Effect (BS): Hooked

Target Stat:ChainHook / IntClamped / Hooked

Value:1

Processor:Add_Int

Apply Type:Temporary

At the start of the pulling state, we use a Linker to copy the enemy's position to the GrapPosition Stat. This Stat is updated whenever the enemy moves.

The Tweener Stat then uses the Start and GrapPosition Stats to interpolate the player's position toward the enemy.

HookPullTween — Stat (Tweener Vector3)

Stat (Tweener Vector3): HookPullTween

We also set the Hooked flag to true.

A StateBasedTrigger Stat listens for the Hooked flag and starts the pull tween when the flag is enabled.

TriggerHookedEffects — Stat (StateBasedEffect)

We also have a ConditionalModifier assigned to SkillEvolutionNo.

ChainHook_EvolutionNo — Stat (Clamped Int)

Stat (Clamped Int): ChainHook_EvolutionNo

Stat Key:ChainHook / IntClamped / SkillEvolutionNo

Max:4

This modifier checks the distance to the closest enemy and determines which state should be activated next.

If the distance check passes, the modifier adds the result to the incoming Effect value. This effectively skips the Punch state at index 3 and activates the Kick state at index 4.

ConditionalEvolutionNoModifier — Stat (ConditionalModifier Float)

Stat (ConditionalModifier Float): ConditionalEvolutionNoModifier

Stat Key:ScrapTossers / ConditionalModifier / ConditionalEvolutionNoModifier

Default:1

Max:1

Single Stat Checker › Condition:NoEnemyInSight

The closest enemy is set when we toggle off the Pull state by pressing the skill button again.

Effect Pack: ToggleOff_2

The closest enemy is then assigned using the following Effect:
