Well after programming in Flash for awhile I've got a nifty idea what I can do with MMF it terms of collision detection, has anybody ever programed trigonometry vector kind of collisions. I don't mean actual visual vectors like in flash but create and emulate vectors that would allow N like phsyics. I wonder if it's possible? Basicly using little objects as possible and faster coding.
I don't write with grammer I write with feeling...

I don't know the answer to your question, but I do have this: The Question Mark ( ? ) is your friend.

I think he means he wants to use maths to do collisions instead of detectors, like have the equasion of a circle to make a circular collision barrier around an object.

(x-a)² + (y-b)² = r²
That's the equation of a circle.
where (a,b) is the centre of the circle.
Alternatively, just x²+ y² = r² relative to (0,0) of the object.
(if you just want it simply, x=rcos(angle) and y=rsin(angle))
both may help.
Anything else?

The person I know managed to do in TGF collisions:
circle-circle
line-circle
line-line
And derived (region-region is just more line-line colls).
And also managed to foresee how much time would it take for objects to collide if you know their start position, velocity, acceleration, angle, angle velocity, angle acceleration.
There is a lot of math, but it isn't as hard as it is boring :---).

Ahhhh, Joe! Yesterday I had my last math exam for this year, on analytic geometry. And first thing I see when I come on TDC is you talking about the equation of a circle. Argh!

Faster coding as in faster to write the code? (or events) or faster to process the code making the game run better?

Thanks, It's not really a real question of if anyone can help me out but more of has anybody thought of this, I know this is just a help forum but I can't seem to find a place to post a topic about this.

1. Is this possible?
>> Yes, it is.
2. Has someone though about it?
>> Yes, and made it also. Anyway, I do not have the rights to give this code.

It is possible yes, but due to MMF's slow looping speed (compared with say, C) it is probably not practical for anything but the most small scale physics engine
Best to just wait it out until vortex's physics extension comes out. Pretty much anything is possible in MMF, but a lot of things quickly become an unacceptabl overhead when you try to implement them into an actual game.

Fastloop was invented to help on that case.
