darn my socks found it, flip I can be a silly beggar, as it was right there in the examples

this library is the BIZNESS, and now to make a complete plonker of myself: How did you draw the lines on the example swfs?

hi Drew, veyr interesting stuff, I have similar questions to Andrey.
i’m thinking of utilising your engine for a racing style game to using as a fixed track path but would need to be able to:
a) control the velocity / increments along the path
b) break connection to the path
c) restart at any point along the path
d) loop the path
e) interogate the object to know it’s x,z and rotation
f) control the object rotation
g) get the current vectors of the path (to keep associated graphics orientated to the path (signs etc)

can you tell me which if any / all are possible with your engine?

regards, and great work, Rich

Ive recently become a big fan of Foam. I finding it really easy to work with and understand for some games i have been working. I am wondering what happened to SLRBS?

Comment on FOAM Rigid Body Physics Engine Alpha Release 0.1 by AS3 opensource project « Sharring Your Life

[...] 17. FOAM FOAM is primarily intended as a resource for developers interested in simulating physics. It has a carefully thought out OOP structure and modular design. A savvy developer should have no problem extending and repurposing FOAM to his own ends. The Foam datatype is in fact not a physics engine but an interface for simulating physics. It offers a simple means to create, control and run a simulation- it purposefully keeps the more nitty gritty, behind-the-scenes operations shielded from the casual developer. A physics engine is simply part of its composition. [...]

Much Thanks!! Nice work.
Another implmentation:

// Line segment between MovieClip(A) and MovieClip(B).
private function Loop(e:Event):void
{
var mouseVec:Vector2D = new Vector2D(stage.mouseX, stage.mouseY);
var aVec:Vector2D = new Vector2D(Ball1.x, Ball1.y);
var bVec:Vector2D = new Vector2D(Ball2.x, Ball2.y);

// Calc closest point
var P:Vector2D = ClosestPoint(
mouseVec,
aVec,
bVec
);

var PCirc:Vector2D = P.GetDifference( mouseVec );
var Mag:Number = PCirc.Magnitude;

// Occours
if(Mag 0)
{
PCirc.Multiply(1 / Mag);
}
mouseVec.x += PCirc.x * (Mag – Radius);
mouseVec.y += PCirc.y * (Mag – Radius);
}

Circle.x = mouseVec.x;
Circle.y = mouseVec.y;
}
