Issue: afterEnter event not triggering in custom zone

I encountered an issue while setting up a custom zone for my server. I wanted to apply a condition to the player upon entering a specific area, but I noticed that the afterEnter event wasn’t being triggered, despite the setup being correct.

Upon investigating, I found that removing the true from the following line made the afterEnter event work as expected:

local afterEnter = EventCallback("ZoneEventAfterEnter", true)

You can easily testthis by adding a print statement in the following code:

function afterEnter.zoneAfterCreatureEnter(zone, creature)
print("After enter executes")
if zone ~= self.zone then
return true
end
self.afterEnter(zone, creature)
end

This suggests there might be an issue with the skipDuplicationCheck boolean.

Removing the true causes a series of other problems in the console:

I modified ZoneEvent to add a print to check things out and it printed the stuff in the image, it looks like self.zone is always hazard.gnomprona-gardens, I tried going to gnomprona gardens and hazard seems to be the only working afterEnter event.

if self.afterEnter then
	local afterEnter = EventCallback("ZoneEventAfterEnter", true)
	function afterEnter.zoneAfterCreatureEnter(zone, creature)
		print(zone:getName())
		print(self.zone:getName())
		if zone ~= self.zone then
			return true
		end
		self.afterEnter(zone, creature)
	end

	afterEnter:register()
end

The error likely stems from the fact that you r trying to create a second instance of the afterEnter variable and assign it a new event callback, which could be causing a conflict with another EventCallback object already in place. To avoid it, you can refactor the code to check if self.afterEnter is already assigned or modify the logic to avoid re-registering the same event callback multiple times.

Note: in the console tells you exactly what it is

I think you misunderstood how to use the afterEnter and afterLeave zone events, you are overwritting the afterEnter of all other zones, to use an afterEnter and afterLeave event of a single custom zone, you should use this way:

local zone = Zone("thais.temple.exit-entrance")
zone:addArea({ x = 32367, y = 32227, z = 7 }, { x = 32371, y = 32230, z = 7 })

local zoneEvent = ZoneEvent(zone)
function zoneEvent.afterEnter(_zone, creature)
	-- YOUR CUSTOM BEHAVIOUR AFTER A CREATURE ENTERS GOES HERE
end

function zoneEvent.afterLeave(_zone, creature)
	-- YOUR CUSTOM BEHAVIOUR AFTER A CREATURE LEAVES GOES HERE
end

zoneEvent:register()
