Some problems with reactions (MAX)

[PEN]

If you can hold on Chris is just editing my DVD#4 on this very subject.

I use this joystick manipulator http://www.rgba.org/r3d/maxscripts/JoystickManip01.ms, it allows you to get both x and y values. It works great for me. I have also seen it done with a bezier position controller on the master, that will also allow u to get both x and y values.

You may need to pull in a fix shape for this, ive written a script that'll basically do Michael pose space deform. I.et you model the combination you like to achieve and it makes the fix shape. Plus this is the problem with reactions. Can you use a list_controller and drive the morphs values via an expression.

Ive got the SS book here, he seems to use expressions all over the place:

mel:

brows.translateY = ctrl.brows.translateY/15

Basically your saying, you need the shape to drive four inputs right? well id use the script controller or expression controller. Open up the graph editor and select the morph. Add a script controller. Make a new variable like "test" and assign it as a node to the shape control.
Then use:

e.g. test.pos.z/2

something like this anyway. You can even instance the controller, by:

a = $shape.modifier[#morph].weight1

you could even instance the controller by evaluting something like:

$morphshape.modifiers[1][1].controller = $controlshape.position.controller.z_position.controller

eek

Thanks, eek, you're a life saver as always, dude ;) What I've finally done is control 4 targets with a controller ist: X is controlled by 'reaction controller', and Y by an expression. I was messing up my mind with expressions when accidentally I type wrong the line and... it worked! After that, I guessed what was wrong.

Thanks for script too: that's what I was looking for, but I didn't know how to write it (I started to read the whole MAXScript help some days ago).

Oh, by the way, d'you remember I was doing one reel? I got the job! In april I'm working in a spanish animation studio called 'Renderboy Studios'. And it's thanks to you and Mark, who helped me out with some technical stuff ;););)

MOSS, I was using a Joystick Manipulator already ;)

Paul, thanks for your answer.

hey guys,

i have a little technique to do this kind of stuff with param wiring.

not sure it works with joystick manipulators because you need your driving object to have a point3 position controller

you basically wire the position (not one of the subcontrols eg. x y and z but the position itself) to the morph target

you can then use the individual axis of the position to set up your formula in the wiring expression. for example something like this

if position.x > 0 then position.y else (1+position.x) * position.y

something like this would be the expression for the upper right corner of the control

makes setup fairly easy and it's more straight forward to script this than expression controllers (especially for anything prior to max 8 where you needed the exprctrlop plugin to script expression controllers

ikerclon i actually have a script that may help you out as well, i just made quick video tutorial on how to use it and posted it on my site (the script itself you can find a part of the soulpix script package further down on my site)

i only tested the scripts in 8 though
