Ok I am trying to change over old code (Actionscript 1.0) to use Fuse in Flash 8.

Old code uses:

this.\_x = Math.easeInQuad(this.t, 0, gox, 6);

So my new code in Flash 8 would be:

import com.mosesSupposes.fuse.\*;  
ZigoEngine.register(PennerEasing);  
this.\_x = PennerEasing.easeInQuad(this.t, 0, gox, 6);

Is that all I need to do to do an easeInQuad? Do I have to declare/define it somewhere or is the equations, parameters it accepts builtin to Fuse?

Thanks.
