soon ( before June ) - mcjReach - Pose helper script

mCasual · May 2015

you select a target, for example a null node at the surface of a desk

you select a targeter, for example Amy's right index finger

you select the actor, for example Amy's abdomen joint

from the list of 6 transform properties, you select one, for example the Bend property

click the Go button

quicker tan the eye can see, mcjReach will try 30 bend angles for the Abdomen

( 3 degrees smaller to 3 degrees greater than the current bend angle )

it will set the Abdomen angle to the angle that minimizes the distance between the targeter and the target

you can then repeat the process with the hip, chest, shoulder, forearm etc etc until the target is reached

There will be a special mode named "Assisted"

The "reach" operation will involve a node named "The Pointer"

this is somewhat similar to what mcjAutoLimb does but slightly more universal

---------

Example

the Target is just above the bell-ringer's button
the Targeter is just below Amy's index finger tip
the Actor is the hand's Bend control
the Pointer is the rShoulder - but we could have chosen the rCollar, the chest, the abdomen or the hip

recall that the normal ( using the Go Button ) process is to
test 30 Hand Bend angles and keep the Bend angle that minimizes
the distance between the targeter and the target

the special "Assisted" process is to test 30 Hand Bend angles
and keep the Bend angle that minimizes
the difference between
the distance from the Pointer ( shoulder ) and the targeter
and
the distance from the Pointer ( shoulder ) and the target

why? because this way the length of the arm is ideal

mcjReach then re-points ( hence the name Pointer ) at the target

( we say the arm, but in fact it's the imaginary line going from the shoulder to targeter )
