Centering Graphical Score

[Keith]

For my non side-scrollers I usually center my graphical score (it uses a non-proportional font) using this algorithm:

(Frame Width/2)+((X Right( "Score" )-X Left( "Score" ))/2)

This works fine without any virtual real estate, but how would I calculate it out for a viewport? I have set the score to NOT follow the frame.

So you mean for a scrolling game? Just turn off follow the frame and then put the score object in the center of your frame?

Also if you can, just set the hotspot of your graphical score to the center of itself... that way you don't even have to do the second part of your calculation...

You'd just figure out the center of your frame (if you had a 640px wide frame, it would be 320px) and place the object there in the editor. If the object's hotspot is center, it should be centered up.

I'm sorry, I am using the score object with Images and because the fonts are not proportional I have to calculate the width every time and center it. Not sure how to get the viewport coords.

If the object isn't scrolling, then it's always just real x/y values. So if you tell MMF to put an object at 100,100 and the object has follow the frame turned off, then that object will always appear at 100,100 on the screen (not the frame)

Okay, I want it to always be centered on the screen. I can't seem to get it to do this. How can I get the Viewport X1 and X2? The viewport being the visible part of the screen within my much larger Frame.

This should work:
(X Left Frame + (X Right Frame - X Left Frame)/2) + ((X Right( "Score" ) - X Left( "Score" ))/2)

That worked perfect. Thanks!
