I usage silent_login by default and “Login” button on main screen for those players, who disabled silent mode.

The Google Play Game Services extension has been updated with a crash fix for gpgs.leaderboard_get_player_score(). The new version also contains a fix for general error handling where error messages weren’t correctly formatted.

There’s also ongoing work to fix a scenario where gpgs.leaderboard_submit_score() doesn’t log the correct score in the leaderboard: https://github.com/defold/extension-gpgs/issues/25

How to unlock achievement? I’ve read the documentation but I’m bit confused about unlock, show and get functions?

And can I retrieve players highscore from leaderboard?

You unlock achievements by calling gpgs. achievement_unlock(achievement_id):

I think you want the gpgps.achievement_show() function:

In fact, you can check the example project if you are unsure of how to use GPGS:

github.com

defold/extension-gpgs/blob/master/main/achievements.gui_script

local dirtylarry = require "dirtylarry.dirtylarry"
local monarch = require "monarch.monarch"


function gpgs_callback(self, message_id, message)
	print(message_id)
	pprint(message)
end

function init(self)
	msg.post(".", "acquire_input_focus")
	if gpgs then
		gpgs.set_callback(gpgs_callback)
	end
end

function on_input(self, action_id, action)
	dirtylarry:button("reveal", action_id, action, function ()
		if gpgs then
			gpgs.achievement_reveal("CgkIq5-gxcsVEAIQAQ")

              self.clicks = self.clicks + 1
              print(self.clicks)
              gui.set_text(gui.get_node("clicks"), tostring(self.clicks))
          end
          
          
dirtylarry:button("submit_score", action_id, action, function ()
              gpgs.leaderboard_submit_score("CgkIq5-gxcsVEAIQAg", self.clicks)
          end)
          
          
dirtylarry:button("top_scores", action_id, action, function ()
              gpgs.leaderboard_get_top_scores("CgkIq5-gxcsVEAIQAg", gpgs.TIME_SPAN_ALL_TIME, gpgs.COLLECTION_PUBLIC, 10)
          end)
          
          
dirtylarry:button("player_centered_scores", action_id, action, function ()
              gpgs.leaderboard_get_player_centered_scores("CgkIq5-gxcsVEAIQAg", gpgs.TIME_SPAN_ALL_TIME, gpgs.COLLECTION_PUBLIC, 10)
          end)
          
          
dirtylarry:button("player_score", action_id, action, function ()
              gpgs.leaderboard_get_player_score("CgkIq5-gxcsVEAIQAg", gpgs.TIME_SPAN_ALL_TIME, gpgs.COLLECTION_PUBLIC)
          end)

          or message_id == gpgs.MSG_GET_TOP_SCORES then
              local s = ""
              for _,score in ipairs(message) do
                  score = json.decode(score)
                  s = s .. ("%s - %s (%s)\n"):format(score.score_holder_name, score.display_score, score.display_rank)
              end
              gui.set_text(gui.get_node("scores"), s)
          end

What does achievement_get do? API doc doesnt have any description on that one.

britzl · February 23, 2023, 10:25pm

Almost all Google Play Game Services APIs are asynchronous which means that you do not get the data immediately in the function call but some time later in a callback. In the example the achievement data is received in the callback here:

github.com

defold/extension-gpgs/blob/master/main/achievements.gui_script#L5-L15

    
      
          function gpgs_callback(self, message_id, message)
          	print(message_id)
          	pprint(message)
          end
          
          
function init(self)
          	msg.post(".", "acquire_input_focus")
          	if gpgs then
          		gpgs.set_callback(gpgs_callback)
          	end
          end
