Volume Select Gizmo

[Anonymous]

Hey...

Im tearing my hair out trying to figure this one out... I'm making a tool for quickly setting up muscles between two points, and the code is this;

macroscript muscleSetup
 category:"Toke Scripts"
(
 fn muscleBone type =
 (
 p1 = selection
 p2 = selection
 
 muscle = BoneSys.createBone p1.pos p2.pos 
 
 muscle.boneFreezeLength = off
 muscle.boneScaleType = type
 
 muscle.position.controller = Position_Constraint ()
 muscle.position.controller.appendTarget p1 100
 muscle.rotation.controller = Lookat_Constraint lookat_vector_length:0
 muscle.rotation.controller.appendTarget p2 100
 
 muscleNull = BoneSys.createBone   
 
 muscleNull.pos = p2.pos
 muscleNull.parent = muscle
 
 muscleNull.position.controller = position_constraint ()
 muscleNull.position.controller.appendTarget p2 100
 )
 fn muscleCylinder type =
 (
 p1 = selection
 p2 = selection
 
 dist = (distance p1.pos p2.pos)
 
 muscle = cylinder height:dist sides:8 heightsegs:5
 
 muscle.pos = p1.pos
 muscle.boneEnable = true
 
 addmodifier muscle (xform())
 muscle.modifiers.gizmo.rotation += quat 0 0.707107 0 0.707107
 
 addmodifier muscle (volumeselect level:1 useAffectRegion:true falloff:(dist/2))
 muscle.modifiers.gizmo.scale = 
 muscle.modifiers.gizmo.position = 
 
 --searching through scene for other muscles and instances modifier
 flexMuscles = for i in geometry where i.boneEnable == true and classof (i.modifiers) == flex collect i
 
 if flexMuscles.count > 0 then
 (
 tempMod = flexMuscles.modifiers
 addmodifier muscle tempMod
 )else
 (
 addmodifier muscle (flex flex:0.16 strength:4 sway:15)
 )
 
 muscle.boneFreezeLength = off
 muscle.boneScaleType = type
 
 muscle.position.controller = Position_Constraint ()
 muscle.position.controller.appendTarget p1 100
 muscle.rotation.controller = Lookat_Constraint lookat_vector_length:0
 muscle.rotation.controller.appendTarget p2 100
 
 muscleNull = BoneSys.createBone   
 
 muscleNull.pos = p2.pos
 muscleNull.parent = muscle
 
 muscleNull.position.controller = position_constraint ()
 muscleNull.position.controller.appendTarget p2 100
 )
   rollout rollout_muscleSetup "Muscle Setup"
 (
 group "Step 1"
 (
 label lb1 "Select two points."
 )
 group "Step 2"
 (
 label lb2 "Choose type"
 radiobuttons muscleType labels:#("scale","squash")
 )
 group "Step 3"
 (
 label lb3 "Choose muscle"
 button cylinderBN "Cylinder w. Flex"
 button boneBN "Bone"
 )
 on boneBN pressed do
 (
 if muscleType.state == 1 then
 (
 muscleBone #scale
 )else
 (
 muscleBone #squash
 )
 )
 on cylinderBN pressed do
 (
 if muscleType.state == 1 then
 (
 muscleCylinder #scale
 )else
 (
 muscleCylinder #squash
 )
 )
 )
 createdialog rollout_muscleSetup style:#(#style_titlebar,#Style_toolwindow,#style_sysmenu)
)

The tool stops when trying to access the vol. select modifiers gizmo, and says "Unknown Property". When I copy the exact same code into the listener and execute it, I get the gizmo scaled down and repositioned as I want it.

Has anybody had similar problems or know of a solution?

addmodifier muscle (volumeselect level:1 useAffectRegion:true falloff:(dist/2))
completeRedraw() -- seems that volume select gizmo can only be accessed after it has been registered properly in the scene, so force a complete redraw
muscle.modifiers.gizmo.scale = 
muscle.modifiers.gizmo.position = 

It's not that elegant, almost feels like a bug, but it works.

Perfect! nevermind about the elegance:-) Here is the finished script:
