Method Details

isFulfilled

protected abstract boolean isFulfilled(GameContext context,
 Player player,
 ConditionDesc desc,
 Entity source,
 Entity target)

isFulfilled

public final boolean isFulfilled(GameContext context,
 Player player,
 Entity source,
 Entity target)

Is the condition fulfilled given the specified source and target?

Uses the getDesc() desc this was constructed with for many parameters.

target is context-sensitive. When used in EventTriggerArg.QUEUE_CONDITION or EventTriggerArg.FIRE_CONDITION, source is the GameEvent.getSource() and target is the GameEvent.getTarget(). The trigger's host is typically accessed using EntityReference.TRIGGER_HOST.

Parameters:

context -

player -

source -

target -

Returns:

isFulfilledForTarget

protected boolean isFulfilledForTarget(GameContext context,
 Player player,
 Entity source,
 Entity target,
 TargetPlayer targetPlayer)

setDesc

public void setDesc(Desc<?,?> desc)

Specified by:

setDesc in interface HasDesc<ConditionDesc>

getDesc

public ConditionDesc getDesc()

Specified by:

getDesc in interface HasDesc<ConditionDesc>

targetConditionArgOverridesSuppliedTarget

protected boolean targetConditionArgOverridesSuppliedTarget()

When true, ConditionArg.TARGET is evaluated instead of being interpreted by the subclass, replacing target if it is specified.

When false, only target is passed.

Returns:

multipleTargetsEvaluatedAsAnd

protected boolean multipleTargetsEvaluatedAsAnd()

When targetConditionArgOverridesSuppliedTarget() is true, the result of the condition on each of the resolved targets is and-ed if this is true.

Should not be true when multipleTargetsEvaluatedAsOr() is also true.

Returns:

multipleTargetsEvaluatedAsOr

protected boolean multipleTargetsEvaluatedAsOr()

When targetConditionArgOverridesSuppliedTarget() is true, the result of the condition on each of the resolved targets is or-ed if this is true.

Should not be true when multipleTargetsEvaluatedAsAnd() is also true.

Returns:

singleTargetOnly

protected boolean singleTargetOnly()

Expects a single target only. Used in conjunction with targetConditionArgOverridesSuppliedTarget().

Returns:

requiresAtLeastOneTarget

protected boolean requiresAtLeastOneTarget()

When true and multipleTargetsEvaluatedAsAnd(), there must be at least one target in the resolved targets.

Returns:

usesFilter

protected boolean usesFilter()

Filters the target or ConditionArg.TARGET with the ConditionArg.FILTER.

Returns:

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
