Just like ByR said:
Make a global variable "Points"
Event: System -> Every 0.1 seconds
Action: Add to: Points, Value: 10
Then you can add a text object and place it in the Layout, example:
Add a text object -> Name it text_points
Then add to the previous event
Action -> text_points -> Set text -> "Points: " & Points
This way, every 0.1 second that points are added, you'll see them in the text object.
You can also place the text_points -> Set text in another event, for example Every tick. That way the text object is updated every tick.
Hope this helped.
