How can i add achievements to my Game ?

Hello i want to add achievements like in the picture to my game :



i have already added my :
1 - leaderbord ID : "CgkImffl4eQeEAIQAs"
2- Game Services ID : "1057840790475"
3- my licence key also !

but i have not upload my apk game to google play yet !

i compiled my game trough eclips , and when i open it
it try to sign in to Google Play Games and it shows me an error : ( Google play sevices : sign in error )

Can any one help me ! ( sorry my English is little bit weak )

 

there is no way to added achievement with buildbox you need a programmer/ you need to remove leaderbord ID and Game Services ID it mean to be secret

 

Thank you , don't worry those are not my real Secret codes ^^ !

 

i have added it , just i forgot a number from my game services , now it's working

 

are you talking about achievement how did you added it

 

up tell us how have you had the achievements @bahaeeddine2010 ? because has i know we can only add an leaderboard with game services sdk

 

no i am just talking about leaderboard

 

How can I link the leaderboard to a button on the menu ?
Im really clueless :/

 

@mnodl Say you want to add the game center to your main menu - you would open the main menu, pull a button control onto the screen, and set the button to 'game services'
