L2DamageTracker

This mod adds attack tracker and damage type multiplex. Attack tracker is a way for mods to better listener to the attack event series, with access to information that would have been modified in other events.

Damage Type Multiplex is a system that allows mods to change the damage type based on scenarios, by enabling or disabling certain flags. Similar to BlockState, all possible DamageType must be generated beforehand.

Installation

Requires:

• L2Serial
• L2Library

Compatibility:

• L2Tabs

Usage

Attack Tracker

To register an attack tracker, use AttackEventHandler.register.

To modify damage, you should use AttackCache.addHurtModifier or AttackCache.addDealtModifier. They adds an entry to the pool for later calculation. To synchronize calculations across mod, we let mods add damage modifiers instead of modifying the damage values directly. This allows better control over inter-mod behavior.

List of damage modifier types in order:

• nonlinearPre: Nonlinear modification before everything else.
• multAttr: Multiplicative modification, serves the same function as AttributeModifier with operation of MULTIPLY_TOTAL.
• add: Additive modification for general purpose.
• MultBase: Multiplicative modification with Operation.MULTIPLY_BASE
• multTotal: Multiplicative modification for general purpose.
• nonlinearMiddle: Second nonlinear modification
• addExtra: Extra damage that should not be scaled by others
• nonlinearPost: Final layer of nonlinear modification

Damage Type Multiplex

To use damage type multiplex, you need to define your DamageState and register them to corresponding DamageTypeRoot. Then you need to configure generator to generate all relevant data.

To generate damage types, you must specify your namespace, and namespace of DamageState that you would support. To prevent missing damage types, mods should generate data with a clear dependency.

To set the damage state, use attack tracker to listen to CreateSourceEvent, which will only fire to attack trackers.
