Script init function never executes for collectionfactory collection

Questions
1

Hey everyone, I’m running into a very frustrating issue. I’m trying to figure out why for some reason my script attached to multiple collections never is running the init function. I’ve posted a video here showing the problem:

2

Does any script attached to them run init?

3

go.property() needs to be run outside of any functions

4

Thanks I just added that but moving it outside doesn’t affect this issue. I created a “test” script and attached it to one of the maps, and it does initialize. Not sure why this script isn’t working. I want to use the same script for all the instances since the logic there is the same for all maps. Is this not supported?

EDIT: I attached the same test script to all instances and it inits each time. Why is this script not doing anything? There’s no error printout it just doesn’t activate for some reason.

This kind of thing is supported, the only thing to really keep in mind is that any global variables will be shared across each instance. Does it work if you use print statements instead of breakpoints?

6

Yeah printing is fine, but the debugger doesn’t stop in the init function so I have no idea of why the script won’t work when I load a second level. I’ve been running into quite a few debug issues though.

7

Aside from the breakpoint not working and some console errors, I don’t see anything going wrong in the video. Could you explain more about what the issue is?

8

The logic for the script isn’t consistent when I initialize for a second map. Do you know if there’s a way to create a new script instance for an object? When I load a level the second time, it fails to spawn the player even though it will work if it’s the first map to be loaded w/ that script attached.

Like I said before, global variables will be kept between script instances. There’s probably something in your logic that breaks because of that. The self table doesn’t carry between instances, so use that.

Here’s the entire script for the dungeon instance. I have some globals, but I want to affect these objects/variables interdependently from the level instance:

require "helpers"
require "level_helpers"
require "progress"
require "singletons"

go.property("sub_level", 0)

function init(self)
	self.entities = {}

	level_ref = msg.url()

	self.level_init = true

	self.pusher_block_nodes = {}
	table.insert(self.pusher_block_nodes, { pos = vmath.vector3(46 * wall_width, 16 * wall_height, 0.5), time_scalar = 250 } )
	table.insert(self.pusher_block_nodes, { pos = vmath.vector3(46 * wall_width, 14 * wall_height, 0.5), time_scalar = 50 } )
	table.insert(self.pusher_block_nodes, { pos = vmath.vector3(4 * wall_width, 14 * wall_height, 0.5), time_scalar = 250 } )
	table.insert(self.pusher_block_nodes, { pos = vmath.vector3(4 * wall_width, 16 * wall_height, 0.5), time_scalar = 50 } )
end

function update(self, dt)
	if self.level_init then
		level_helpers.init(self)
		self.y_max = self.y_max + 2
		self.x_max = self.x_max + 2
		self.portal_locs = {}
		local portal_locs = level_helpers.find_portals(self)
		level_helpers.spawn_entities(self)
		msg.post(main_ref, hash("load_fx_descent"))
		local portal_1 = level_helpers.multiply_portal_loc(portal_locs[1].x, portal_locs[1].y)
		table.insert(self.portal_locs, { level = hash("use_map_main"), x = portal_1.x, y = portal_1.y, spawn = true } )
		msg.post(main_ref, hash("set_portals"), self.portal_locs)
		msg.post(main_ref, hash("set_death_event"), { event = hash("load_level"), level = hash("overworld"), sub_level = hash("base") })
		prg_keys = 0
		self.level_init = false
	end
end

function on_message(self, message_id, message, sender)
	if message_id == hash("add_entity") then
		table.insert(self.entities, message.id)
	elseif message_id == hash("spawn_switch") then
		self.switch_id = factory.create("#switchfactory", vmath.vector3(message.x, message.y, 0.5), nil, nil, 1)
		table.insert(self.entities, self.switch_id)
	elseif message_id == hash("spawn_key") then
		local key_id = factory.create("#keyfactory", vmath.vector3(message.x, message.y, 0.5), nil, nil, 1)
		table.insert(self.entities, key_id)
	elseif message_id == hash("switch_triggered") then
		if self.sub_level == 5 then
			for x=12,14 do
				tilemap.set_tile("#map", "walls", x, 8, 0)
			end
			for x=22,24 do
				tilemap.set_tile("#map", "walls", x, 8, 0)
			end
			for x=33,35 do
				tilemap.set_tile("#map", "walls", x, 8, 0)
			end
		end
	elseif message_id == hash("get_path_nodes") then
		msg.post(sender, hash("start_moving_on_path"), self.pusher_block_nodes )
	end
end

function final(self)
	go.delete_all(self.entities)
	if player_ref ~= nil then
		msg.post(player_ref, hash("heal_player"))
	end
end

EDIT: Would anyone be available for a video conference to try to sort this out? This seems like an engine bug but I have put too much work into this project to simply post it online.

Which part of the logic? How is it not consistent?

I managed to fix it. I had to re-construct the entire parent collection from an external script and pass the sub_level property into the main script. It seems the issue is creating a collectionfactory from within another collectionfactory. Not sure exactly why it didn’t work the original way.
