RoRR Modding Toolkit

v1.2.19

v1.2.18

• Instance : Fixed a crash with exists where the CInstance was bad for some reason.

v1.2.17

• Buff : Internal optimization for a few common callbacks.
• Item : Internal optimization for a few common callbacks.

v1.2.16

• Interactable_Object : Fixed error when clear_callbacks runs with no onCheckCost callbacks registered
• Equipment : onUse now provides embryo boolean

v1.2.15

• Fixed incorrect health regen values in survivor logs.

v1.2.14

• Updated repo links.

v1.2.13

• Object : Added onSerialize/onDeserialize for syncing custom objects in netplay.

  • Removed previously existing onPreStep and onPostStep.

v1.2.11

• Alarm : Fixed create args being nil for args past the first one.
• Skill : Now overwrites callback_execute result.value if a non-nil value is returned.

v1.2.10

• Player : Removed internal callback that automatically froze default skill cooldown while an override was active.
  • Even though this is most likely desired in 99% of cases, it is better to allow the user control over it.
• Actor
  • Added freeze_default_skill, freeze_active_skill, and freeze_other_overrides (to aid with the above)
  • Added override_default_skill_cooldown and override_active_skill_cooldown

v1.2.9

• Actor : fire_ methods now default to sNone instead of -1 if no sprite is provided.
  • Otherwise damage numbers do not show for clients.

v1.2.8

• Callback, Callback_Raw : add can now accept numbers from Callback.TYPE enum.

v1.2.7

• Instance : Getting from an invalid instance will now return nil.

v1.2.5

• Item, Equipment, Buff, Instance, Actor, Player

• Resources
  • Calling sprite_load for an existing sprite now allows you to modify the sprite's origin.

  • sfx_load now returns the existing sound ID for a namespace-identifier that already exists.

v1.2.4

  • Mostly redundant; just add a Callback and check with is_active
  • Also lack of control over onActive/onInactive

    • Namely, callbacks that passed "damager" will now either pass attack_info or hit_info.

• Item, Equipment : Added is_loot
• Callback : Fixed remove not actually doing anything.
  • Also fixed various remove_callbacks that may or may not have been broken.
• Actor : fire_ methods now have an optional can_proc bool argument (default true).
  • fire_ methods also return the attack instance only now.
  • buff_remove now calls recalculate_stats when removing stacks.
• Helper
  • Added is_true and is_false
  • Added read_json
• Instance : Fixed get_data pulling a different table in certain circumstances.
• Array, List : new overload: can now supply a lua table as a single argument.
• Monster_Log : new now takes in namespace, identifier instead of a monster card.
• Alarm
  • create now returns the alarm table.
  • Added destroy
