GUI issue

I’m trying to debug my game as it no longer plays on HTML5 or Android. I’ve seeing in my menu for launching the game that the message when I click the play button is sent 3 times instead of once in the below code:

function init(self)
	msg.post(".", "acquire_input_focus")
	msg.post("@render:", "use_fixed_projection", { near = -1, far = 1 })
	release_buttons(self)
	self.pressed_button = nil
	sound.play("#bgm2")
	self.released = false
end

function final(self)
	-- Add finalization code here
	-- Learn more: https://defold.com/manuals/script/
	-- Remove this function if not needed
end

function update(self, dt)
	self.released = false
end

function on_message(self, message_id, message, sender)
	-- Add message-handling code here
	-- Learn more: https://defold.com/manuals/message-passing/
	-- Remove this function if not needed
end

function release_buttons(self)
	local node = gui.get_node("playgamebutton_depressed")
	gui.set_enabled(node, false)
	self.pressed_button = nil
end

function push_buttons(self, x, y)
	local node = gui.get_node("playgamebutton")
	if gui.pick_node(node, x, y) then
		local node = gui.get_node("playgamebutton_depressed")
		gui.set_enabled(node, true)
		sound.stop("#bgm2")
		self.pressed_button = hash("play_game")
		return
	end
end

function activate_pressed_button(self, x, y)
	if self.pressed_button == hash("play_game") then
		local node = gui.get_node("playgamebutton")
		if gui.pick_node(node, x, y) then
			if self.released == false then
				msg.post(game_ref, hash("load_proxy"), { proxy = "#mainproxy", level = hash("tutchambers1") })
				self.released = true
			end
		end
	end
end

function on_input(self, action_id, action)
	if action_id == hash("touch") then
		push_buttons(self, action.x, action.y)
	end
	if action.released then
		activate_pressed_button(self, action.x, action.y)
		release_buttons(self)
	end
end

The line “msg.post(game_ref, hash(“load_proxy”), { proxy = “#mainproxy”, level = hash(“tutchambers1”) })” is executed 3 times when I set a breakpoint there. I’m unsure why this is happening but the game crashes once the level loads on those platforms. PC is unaffected and I only see “ERROR:GAMESYS: Could not get the tile since the supplied tile was out of range” because I’m simply tolerating that as a result of there not being a tile_exists function for now.

Anyone seen this or can explain to me? I think it may be a result of action.released occurring multiple times after releasing the mouse left button (or touch screen press.) Shouldn’t this action only occur for one loop up the input?

You don’t check what action it is?
What if you print out the name of the action triggering it?

	if action.released then
		pprint(action_id, action)
		activate_pressed_button(self, action.x, action.y)
		release_buttons(self)
	end

Also note that this code will continuously call the push_buttons() function.

	if action_id == hash("touch") then
		push_buttons(self, action.x, action.y)
	end
