[Closed] spring controller On/Off

Turning the iterations to 0 the X,Y,Z to 0 or if the spring is in a list turning the weight of the list to 0 all will stop the spring controller from evaluating.

Not sure if this is the best way but this should get you started,

make a selection set of all your spring controlled objects so you can easily select them all.
in the listener type:

[size=2]for i in selection do (i.pos.controller.steps = 0)

this sets all the spring controller iterations to Zero. For spring controllers nested in position lists try:

[size=2]for i in selection do (i.pos.controller.Spring.controller.steps = 0)

You could convert this into a button, or add a bit of conditonal code to make an on/off toggle button.
[/size][/size]

I don’t make selection set of all my spring controlled objects.because so many files…
First of all, I want to search all the spring controlled object in the file and then
change the iteration value of the objects.

Then how can I make the script for searching the spring controlled objects?

You will need a recursive functions that searchs for spring controllers as they could be any amount of list controllers deep on the position track.

I don’t have time to whip you up one now but I will see what I can do later for you.

Try this out. You could use it to search for any controller by class and then do what ever you want with it.

  cons=#()
  fn searchCons node conClass=
  (
  	if node!=undefined then
  	(
  		if (classOf node)==conClass then
  		(
  			append cons node
  		)
  		for i = 1 to node.numSubs do
  		(
  			searchCons node[i].controller conClass
  		)
  	)
  )
  fn springOnOff steps=
  (
  	cons=#()
  	for o in objects do
  	(
  		searchCons o.pos.controller SpringPositionController
  	)
  	for c in cons do
  	(
  		c.steps=steps
  	)
  )
  
  /* Test
  clearListener()
  springOnOff 2
  */
  

The getClassInstances method is ideal for this:

-- get all instances of the <SpringPositionController>
springCtrlArray = getClassInstances SpringPositionController

-- set the <steps> property for all instances to 2
springCtrlArray.steps = 2

Oh ya right. You know I always forget about that. Thanks for reminding me, I’m so used to writting recursive functions I just go for that each time.
