Usable Abilities
Custom abilities are by default usable (otherwise, how would you use them?). As you saw on the previous documentation page, CustomAbility class already provides you with everything you would need to make a simple usable ability. Just override the OnAdded and OnPressed methods. There's not much to say. It's just that simple.

public class MyUsableAbility : CustomAbility{ public override void OnAdded() { /* ... */ } public override void OnPressed() { /* ... */ }}Examples

/MyAwesomeProject/DragonStomach.cs
using RogueLibsCore;namespace MyAwesomeMod{ public class DragonStomach : CustomAbility { [RLSetup] public static void Setup() { RogueLibs.CreateCustomAbility<DragonStomach>() .WithName(new CustomNameInfo("Dragon's Stomach")) .WithDescription(new CustomNameInfo("You can eat coins to restore your health! That's why dragons hoard all the treasure, right?")) .WithSprite(Properties.Resources.DragonStomach) .WithUnlock(new AbilityUnlock { UnlockCost = 10, CharacterCreationCost = 10, Prerequisites = { VanillaItems.KillHealthenizer }, }); } public override void OnAdded() { } public override void OnPressed() { if (Inventory!.money.invItemCount < 5 || Owner.health >= Owner.healthMax) { gc.audioHandler.Play(Owner, VanillaAudio.CantDo); return; } Inventory.SubtractFromItemCount(Inventory.money, 5); Owner.ChangeHealth(5); gc.audioHandler.Play(Owner, VanillaAudio.BuyItem); gc.audioHandler.Play(Owner, VanillaAudio.UseFood); } }}
