i cant understand what "Set Text1 to Score" means. where i do this ? in event sheet ? in object text1 ?
From your OP"
"action -> text1 /set text "10"
So you have a text on your screen named text1 to hold the score right?
If not you need to create a text to hold the score.
Then click on that text in the events and look at the bottome where it says SET TEXT.
Click on that and it will show two quotation marks. The quotation marks are only used to set the text to words or characters not to a number.
Delete the quotation marks and use your Score variable instead.
Set Text to Score
No quotation marks.
If you have a very large number you will need to make the text box on the layout large enough to hold that number or it will not show up when you run the game.
