A blueprint that gradually rotates the player's lower-body in accordance to the change of posture and facing direction of the upper-body.

A simple enemy AI that chases the player based on sight data using Unreal Engine's built in perception. When the possessed pawn is in range from the player, it launches an attack by calling BP_RandomAttack_Walker, choosing an attack randomly from the 2 movements.

BP_RandomAttack_Walker: selects and sets either Kicking or Slapping status to the Landwalker character

A simple enemy AI that shoots at the player based on sight data using Unreal Engine's built in perception. When the possessed pawn spots the player, it launches a ranged attack by calling Spitter_Attack, which shoots a projectile at the player and alternates to a burst-fire pattern every 4th attack.

Spitter_Attack: checks the attack counter, spawns a projectile and sets the counter. Every 4th attack will be a special "heavy attack" that burst-fires multiple projectiles. 

An optional mini-boss that begins with following the player around. Once the player hits it and brings the possessed pawn's health down to a certain threshold, the pawn's aggressive phase is activated and will transform into a strong hostile force against the player.

• It uses a similar logic to the melee enemy but now calls BP_RandomAttack_Fatty to select a random attack out of the 3 designed attack patterns: charge attack, jump attack, and spin attack. 

• Once the player has damaged the pawn enough, it reaches the final state. In the final state the enemy will be using the same logic and movement set, but now will be transformed into a more dangerous enemy, with extended range and damage on all the previous attacks.

BP_RandomAttack_Fatty: similar logic to the landwalker's random attack function

How damage is applied from AnimationSequence -> BP_Player -> BP_Weapon

Sphere trace that applies damage to any damagable actors that enters the hitbox and spawn VFX at the hit location

using Received_NotifyTick to call a damage trace every tick

damage is taken through blueprint interface

when an enemy is defeated, it will drop items based on the spices, temperature, and moisture of the target. The values of these variables will be passed through a Blueprint Interface to the ItemDrop Actor.

ItemDrop Actor processes the input 

when affected by spices, the value of spices will be stored as pairs in SpiceRegister_Value and SpiceRegister_Name
