Speed calculation

[Boba Fonts]

I wonder if I can convert the pixel-based movement of an active object into a numeric value valid for the MMF built-in movements speeds.

My character is a static active moved by a custom event editor series of events; he moves by a certain amount of pixels every 8 milliseconds to simulate realistic footsteps and avoid a gliding effect. That amount of pixels depends on a scale value, since there's perspective in the game. So he doesn't move by the same amount of pixels in every area of the screen: very few pixels if he's small on top of the screen, near the horizon, and many pixels if he's big, on the bottom of the screen, in a close-up.

I need to measure the "MMF speed" of that pixel-moving character in order to have a bouncing ball thing that moves at the same speed (as precisely as possible) with its built-in bouncing ball movement.

Anyone can help me?
Thanks

After about 1 minute of testing, I figured out that the conversion factor is exactly 0.125.

Speed 60 = 60*0.125 = 7.5 pixels per frame

I'll add a FusionWiki entry for that so you and others can always look it up.

Thank you Looki!

When you say 7.5 pixels per frame you mean the frames the game is rendered in runtime? FPS?

So, now that I know the conversion factor from *pixels per frame* to *MMF speed*, how exactly can I measure the pixels per frame of my character who moves differently based on scale and perspective?

I'm not sure what you mean to be honest.

Are you working with the timer conditions? Every 00'00'08... (By the way, 0.08 seconds are 80 milliseconds, not 8)

You should not use these for movements in the first place.
Rather, make a counter, or a variable, and count it up. When it has reached a certain value set it back to 0 and do something.

Looki I think he means he has a sort of 3D thing with Scaling actives and such.
