A contextual condition: a test that a ContextualRule runs before it uses one of its actions. A condition returns true or false. The rule combines the results with ContextualRule.mConditionRelationship. A null entry in a condition list is skipped.

The situation context

A condition reads the situation context of the unit's contextual action component. The trigger of the situation writes the event data into the context before the rules run. The component also keeps some state across situations. The rule under test is passed to the condition too: ContextualConditionRuleCooldown uses it.

Data Written by Read by
Owner always: the unit of the component unit selector 0
Other unit per situation: the attack target, the kill victim, the damage source, the healer, the spell target, the enemy of EnemyEncounter, the local player's champion in shop situations unit selector 1
Event spell SpellCast, SpellHit, MissileMiss; kill situations write the name and slot of the killing spell IContextualConditionSpell
Spell slots 0-3 refreshed every second: spell, name, slot, level, ready state ContextualConditionSpell
Buff buff situations: buff name hash, new counter value, highest value since the counter was last 0, change of the counter IContextualConditionBuff
Item BuyItem, Purchase: the item id; the last bought item is kept ContextualConditionItemID, ContextualConditionLastBoughtItem
Damage damage situations: the damage result type ContextualConditionDamageResultType
Heal ReceiveHeal and shield situations: the amount ContextualConditionAmountHealed
Kill kill situations: killer, victim, killer team, multikill size, the killer's champion kills unit selectors 4 and 6, ContextualConditionMultikillSize, ContextualConditionKillCount
Owner's killer OwnerDeath: the killer and the killer type; kept afterwards unit selector 5, ContextualConditionKillerType
Level CharacterLevelUp: the new level ContextualConditionCharacterLevel
Animation AnimationEnded: the animation name hash ContextualConditionAnimationName
Map regions region changes: the current region of each region type ContextualConditionMapRegionName
Objective ObjectiveTakeByMyTeam, ObjectiveTakeByEnemyTeam: the objective and the team ContextualConditionObjectiveTakeByMyTeam, ContextualActionObjectiveCountSource
Target point MoveOrder2D and pings: the position ContextualConditionCharacterDistance, ContextualConditionNumberOfCharactersNearTargetPos
Situation history AttackNeutral2D: the last 10 situations, with their times ContextualConditionSituationHasRecentlyRun
User facts ContextualActionUserFactAction: the last 128 facts ContextualConditionUserFactCount, ContextualConditionUserFactSequence

The unit selectors are listed on ICharacterSubcondition.

The trigger resets many event fields after the situation runs. Other fields keep their value. A condition that reads a field outside the situation that writes it compares a reset value or the value of an older situation.

Comparison operator

Conditions with a CompareOp or mCompareOp field use this table. The left operand is the value from the context, the right operand is the value in the bin.

Value Name Passes when
0 Equal value == threshold
1 NotEqual value != threshold
2 Greater value > threshold
3 GreaterOrEqual value >= threshold
4 Less value < threshold
5 LessOrEqual value <= threshold

Any other value makes the comparison fail.
