How Can I Add Coins In Start Ui?

I would like the user to be able to add coins in the Start UI or perhaps a Store UI before starting the game. However, the code is: this.scene()['addScoreCoin'](30);

It gives me an error because I am not in a Scene yet and does not add the coins...is there another way of doing this?

 

Add an object into the UI, go into that objects node map and add an add point node and set it to 30.

 

Oh gosh...thanks for for the answer. Seems so obvious now haha

 

how did you handle this ?
