void TriggerAddUnitEnterRegionEvent(unit unit, Region region, TypedCallback trigger)

This event is triggered when the specified unit enters the specified region. You can use DCEI.TriggeringUnit/DCEI.TriggeringRegion to get the event unit/region in the trigger callback.

• unit unit the unit to trigger the event. Use DCEI.UnitAny to trigger this event for any unit.
• Region region the region for the unit to enter. Use DCEI.RegionAny to trigger this event for any region.
• object trigger the callback function that is called when the event is triggered.

function OnRegionEnter()
    local u = DCEI.TriggeringUnit
    local r = DCEI.TriggeringRegion

    local region_name = DCEI.RegionName(r)
    if region_name = "goal_region" then
        SCORE = SCORE + 1
    end
end

DCEI.TriggerAddUnitEnterRegionEvent(DCEI.UnitAny, DCEI.RegionAny, OnRegionEnter)

• RemoveRegionSync()
• RegionName()
• RevealRegion()
• MoveRegion()

void TriggerAddUnitLeaveRegionEvent(unit unit, Region region, TypedCallback trigger)

This event is triggered when the specified unit leaves the specified region. You can use DCEI.TriggeringUnit/DCEI.TriggeringRegion to get the event unit/region in the trigger callback.

• unit unit the unit to trigger the event. Use DCEI.UnitAny to trigger this event for any unit.
• Region region the region for the unit to leave. Use DCEI.RegionAny to trigger this event for any region.
• object trigger the callback function that is called when the event is triggered.

function OnRegionLeave()
    local r = DCEI.TriggeringRegion
    DCEI.RemoveRegionSync(r)
end

DCEI.TriggerAddUnitLeaveRegionEvent(DCEI.UnitAny, region, OnRegionLeave)

• CreateRegion()
• RemoveRegionSync()
• HideRegion()
