X += (target - X) * .1
I was watching this video, which is very interesting http://www.youtube.com/watch?v=Fy0aCDmgnxg
At about minute 4 in the video they show this formula I have in the title. How would this be translated to an event in MMF? Many of these effects are very cool, especially the one where the ball hits the walls and they "bounch" on the impact. I wonder how these could be translated to mmf code.
+= (stuff) just means Set X to X + (stuff) or Add to X (stuff).
This formula has something to do with easing object so they move smoothly instead of stopping and starting abrubtlyOriginally Posted by SolarB
Plugged it into MMF2, with a Target value of 50 and an initial X value of 0.

Can you show an example how you did it?
Chris I think your numbers are a little off, but I could be wrong...
Care to elaborate?
According to Chris' example, using the numbers 0 and 50 it should look like...
0 += (50-0) * 0.1, which becomes 0 += 5 which is 5
5 += (50-5) * 0.1, which becomes 5 += 4.5 which is 9.5
So yeah, I think Chris' numbers were a little off. I'd assume he was actually using the equation X += (target-X )*0.2, and the last number can obviously be changed to whatever you want anyway. The higher the decimal number is, the faster the object will approach its target. Just mess around with it to see what works best for you.
At any rate, here's an example.
Edit: Oh, I forgot to mention... for the example just press the spacebar to generate a random target location on screen.
Actually yeah, my mistake. I was playing around with different values and I guess I posted the results for the a slightly different equation, X += (target-X )*0.2
Nice example by the way gkinfinity.
Pretty cool stuff they manage to do in the video.
Ill deff check this out when i get the time.
Thanks for posting this Outcast
