I wonder if there is any way to apply to the percentage parameter according to where the object is located manually, in other words I want to create a path and four dummies and when the path constraint is created are kept in that position and apply a percentage value to the path constraint.
$pos.controller.percent = “any method of automatically applying this value and not manually”???
path1 = $Spline_01
pc= path_constraint()
$Point_PT_001.pos.controller =pc
$Point_PT_001.pos.controller.percent = 0
pc.appendTarget path1 50
deletekeys $Point_PT_001.controller #allkeys
Thank you
Don’t know of a built-in way of automatically calculate the offset but if the helpers are on the shape you’ll use as a path, perhaps you could use nearestPathParam () to approximate the percentage.
(
delete objects
sp = converttosplineshape (helix radius1:100 radius2:100 height:400 turns:4 bias:0 direction:0 wirecolor:yellow)
points = #()
for j = 0 to 3 do
(
append points (point pos:[ 100, 0, j*100] wirecolor:green)
append points (point pos:[-100, 0, j*100+50] wirecolor:red)
)
for j in points do
(
constraint = path_constraint()
param = nearestpathparam sp 1 j.pos steps:((curvelength sp)*10)
constraint.percent = param * 100
constraint.appendtarget sp 50
j.pos.controller = constraint
--deletekeys constraint #allkeys
)
)thank you very much PolyTools3D
Exactly as you say, using nearestPathParam results in what you were looking for.
