Init script for the leg. Measure all the parts, and initiate some values.

Constants for the downward motion of the legs.

LEG_ACC = 40;
LEG_FR = 0.2;

How does the spring act when there is no pressure on it?

SPRING_FR = 0.04;
SPRING_ACC = 0.02;

_parent needs this variable to compute the leg the swing angle.

leg_width = cylinder.outer_piston_measure._width;

We must add this variable to the ground.

foot_add = foot.foot_measure._y;

The total length of the leg runs from the center point of the outer piston,

which resides at the movie clip center, to the center point of the foot.

The inner piston (spring) is scaled from its 100px length to whatever

length it should have. The foot is placed where the spring ends.


spring_min_length = spring._xscale;
spring_max_length = foot._x - spring._x;
spring_equilibrium = (spring_min_length + spring_max_length) / 2;

Init some variables

spring_length = spring_min_length;
spring_speed = 0;
foot._x = spring._x + spring_length;

To synchronize the movie, we stop the clip here and call the relevant frames from _parent.

stop ();
