Scoring and Saving Games
Remember in an earlier chapter we talked about saving the game? I bet you thought
I forgot about that, didn't you? I certainly didn't! We will get to that in a moment, but
first we are going to set up the scoring system.
In the scene editor, create a new game-wide attribute; it's going to be an Integer.
Name it
Score
. Now create a new actor, name it
Score
, or something that you'll
remember. Open it up so we can edit it. Change the Size to something small, like 32
x 32. Drag in a Change Attribute behavior, and change it to
Change Attribute:
self.
Color.Alpha
to:
0
. This will hide the actor only when you hit play, so when you are
placing it within the scene, you will see it.
Now drag in a
Display Text
behavior, click on the
e
button to open the expression
editor, and change it to
game.Score
, so it displays the score value:
Finally, don't forget to uncheck the
Movable
option under the
Physics
drop down
to prevent it from falling off the screen, and move it into a non-scrollable layer so it
follows the screen when you start walking.
