Method Idle

Namespace: GrindFest

Assembly: GrindFest.dll

Idle(string, float, bool, bool, bool, Predicate<ItemBehaviour>)

A simple bot that handles basic combat, looting, and survival in a specified area. Call this method repeatedly to make your hero automatically fight and survive.

public static void Idle(string area = null, float healthPotionThreshold = 0.4, bool autoEquip = true, bool autoAttack = true, bool autoLoot = true, Predicate<ItemBehaviour> lootFilter = null)

Parameters

area string: The area where the bot should operate. On level 1 defaults to "Stony Plains".
healthPotionThreshold float: Health percentage (0.0 to 1.0) at which to start drinking potions. Set to 0 or negative to disable potions.
autoEquip bool: Whether the bot should automatically equip better gear.
autoAttack bool: Whether the bot should automatically attack enemies.
autoLoot bool: Whether the bot should automatically loot items.
lootFilter Predicate<ItemBehaviour>: Filter which items to pick up. Default picks up better weapons, health potions and gold.

Remarks

See the following tutorials for more information:

This bot will:

Navigate to the specified area if not already there
Use health potions in two scenarios:
- When below the specified health percentage threshold during combat
- When health is not full and no enemies are around
Attack nearest enemies when health is good
Pick up nearby items when no enemies around
Run around exploring when nothing else to do

Basic Usage:

// Just call Hero.Idle() to use the basic bot
Hero.Idle();

Idle in specific area:

Hero.Idle("Crimson Meadows");

Idle but only use potions when health drops below 30%

Hero.Idle(healthPotionThreshold: 0.3f);

Idle but don't use potions and don't auto-equip items:

Hero.Idle(healthPotionThreshold: 0, autoEquip: false);

Using lootFilter to customize what items to pick up:

// A lootFilter is a function that looks at each item and decides if we should pick it up
// It returns true if we should pick up the item, or false if we should ignore it
// Pick up everything:
Hero.Idle(lootFilter: item => true);

Copying the source code of this method to your own script is a good starting point for creating your own bot.
