AddTarget - Float scripts

Submitted by Matyrix on Sat, 2010-09-11 15:49

Hello,

How can i use the AddTarget option in float scripts? I dont't want to write a new script to solve this problem, but where i have to write this "AddTarget" to make it works, and what i have to write punctually?...

I searched for solution on scriptspot and cgtalk, but i didn't found what i want, only separated scripts which solve this, i think (hope) it could works without any other scripts...

For example: There is three spheres. (Sphere01, Sphere02, Sphere03). I give to the Sphere01 that it's position controller be a float script, and in this script write that "$Sphere02.pos". So it will be always where the Sphere02 is. But if i link the Sphere02 to the Sphere03, and i move the Sphere03, the 01 is not updated by the script. Only when i move the Sphere02...

What i have to do in this case?

Thanks the answer(s) in advance!

So... I want to use the AddTarget option in float script. Because i have a character rig, and there are a lot of cases where is a good opportunity the AddTarget.
This is why i wrote this little example, because more easy to comment on it.

This sphere example is not my problem, it's just a little model of my problem.

The problem is AddTarget usage.

So please if anybody knows how can i use this AddTarget (what is the right usage by an example, and where i have to write this), please let me know.

Thanks in advance and thanks the comments! :)

Hi Matyrix, an example for

Hi Matyrix, an example for AddTarget usage is available in the help - "float_script - FloatController > Target (Track) Variable". I hope this helps.

-- Example from the help:
obj1 = Teapot() --Create a teapot
obj2 = instance obj1 --Create an instance
obj2.pos = [-100,0,0] --Place the instance 100 units along -X
obj3 = Box pos:[100,0,0] --Create a box 100 units long X
ctrl = float_script()--Create a Float Script Controller
obj3.height.controller = ctrl --Assign Controller to Height of Box
ctrl.addTarget "myTeapot" obj1[4] --Add Target Var. with Teapot Obj.
ctrl.setExpression "myTeapot.Radius" --Set Height to Teapot Radius
ctrl.getTarget "myTeapot" --Get the Target Track as SubAnim value
ctrl.getTarget "myTeapot" asObject:true --Get as Object
ctrl.PrintDetails()--Print the controller details

Check for "SubAnims" (Indexed Access to Animatable Properties) :)

obj1 = Teapot()
obj1[1] --SubAnim:Visibility

obj1[4] --SubAnim:Object__Teapot
obj1[5] --SubAnim:Material

Strangely, wiring fail, but float script works here (Max 2009), just as Veneta said, need to move slider to update the controller. Here is my test (screenshot) - I wrote "$Box02.pos[3]" in the expression (without adding target).

You can instance Sphere01 and

You can instance Sphere01 and Sphere02 position controllers.
The float script will not necessary in this case.
