Create New Enemy

1 - Create the character blueprint

• Create a subclass of BP_AuraEnemy

2 - Base Character Setup

Setup the base character values

3 - Assign a behavior

• Assign a controller class

• The controller contains the behavior tree that automatically runs. To make a custom behavior, refer to the chapter

4 - Setup the drop table

There is a variable in the BP_AuraEnemy that child classes can fill to define a drop table

The key is the class that spawn when character dies and value is the probability of spawning. Any actor class can spawn

Create Playable Character

1 - Create the Character Blueprint

• Create a subclass of BP_PlayerCharacterBase

2 - Base Character Setup

Setup the base character values

Base Character

1 - Setup Mesh and Animations

• Create an animation blueprint for the mesh.

Make a new ABP or instanciate the template animation blueprint or use your own

• Setup the character mesh and its animation blueprint. Also pick a weapon mesh if you need one

• Adjust the mesh position and capsule size

• Create the hit react animation montage

• Setup combat animations

Fill up the map of combat montages in the character defaults combat interface

All possible key are sub tags of CombatMontage.*

A reaction to CombatMontage.HitReact animation is required

To use multiple animation for a same tag, we need to override the behavior of the GetCombatMontage method

2 - Set the combat socket locations

• override the function GetCombatSocketLocation and setup socket for each subtag of CombatSocket.*

3 - Handle death behavior

• override the event Die that executes on the server.

• for enemies, the parent class will execute the multicast event M_HandleDeath. We can override it to defined a custom behavior when the character dies

• The parent call will manage ragdoll, weapon drop, movement stop and remove health widget

• The custom implementation would typically play a death sound and dissolve meshes

4 - Character Class Info

• Create data asset blueprint from CharacterClassInfo

• Set the name of the class

• Set the class tag to a subtag of CharacterClass.

• Add base effects

  • Subclass of GE_StartingAttributes_Base to define primary attributes scaling
  • GE_Character_SecondaryAttributes to scale secondary attributes
  • GE_Character_PassiveRegeneration to grant passive health and mana regeneration

• Add the base abilities

  • The GA_HitReact Ability to have a reaction to damages
  • Any other ability you will need

• Add starting effects

  • GE_RestoreMaxLife to grant full life to the unit when starting game. As the maximum life is only calculated after starting attributes is granted, all unit start with 0 hp.
  • GE_RestoreMaxMana if the unit has mana

• Assign the data asset to the character blueprint
