Im trying to understand this example-code and why or where z_node and node_to_z is defined. All i can see is the "subobject" being defined, not the actual z_node var.
macroscript MoveToSurface category: "HowTo"
(
fn g_filter o = superclassof o == Geometryclass
fn find_intersection z_node node_to_z =
(
local testRay = ray node_to_z.pos [0,0,-1]
local nodeMaxZ = z_node.max.z
testRay.pos.z = nodeMaxZ + 0.0001 * abs nodeMaxZ
intersectRay z_node testRay
)
on isEnabled return selection.count > 0
on Execute do
(
target_mesh = pickObject message:"Pick Target Surface:" filter:g_filter
if isValidNode target_mesh then
(
undo "MoveToSurface" on
(
for i inselection do
(
int_point = find_intersection target_mesh i
if int_point != undefined then i.pos = int_point.pos
)--end i loop
)--end undo
)--end if
)--end execute
)--end script
I'm in need of a script like this but on spline subobject-level, on knots. I'm thinking it will involve looping trough shapes,segments and knots in a nested form and applying a similar intersect-function?
