I’m having a weird problem when working with a list. What I have planned is, that the user is able to create new materials where name and diffuse color values are stored in a list.
Afterwards, the user can then just select objects and assign the currently selected material from the listbox to the viewport object selection.
I can already create materials (at the same time for debug purpose it just also assigns the material righ away on the selected object upon material creation), but as soon as I want to select a different material from the listbox, I get this error:
-- MAXScript Rollout Handler Exception:
-- No ""select"" function for undefined

I do think I know why this is as the material itself is not a propper node (please correct me here if I’m wrong). If I assign objects to the list and select those, it works. So I guess the issue lies somewhere here:
on s3d_LBX_IDMaterialList selected nameIndex do
(
select (getNodeByName s3d_LBX_IDMaterialList.items[nameIndex])
)
So – How can I fix this? Any help is very appreciated!
Thanks
Full code:
try(destroydialog ::s3d_MATERIALTEST)catch()
ClearListener()
--global ColorIDArray = #(#(),#())
rollout s3d_MATERIALTEST "" width:200 height:400
(
button s3d_BTN_SwitchToIDMat "Switch to ColorID" height: 45
listbox s3d_LBX_IDMaterialList "Color ID Materials:"
colorPicker s3d_CPL_ColorID "Color ID" align:#center color:(color 0 0 0) alpha:false
edittext s3d_EDT_ColorIDName "ColorID Material Name" labelOnTop:true text:""
button s3d_BTN_CreateIDMaterial "Create ColorID Material" width:150
button s3d_BTN_RemoveIDMaterial "Remove ColorID Material" width:150
button s3d_BTN_SaveAllMaterials "Save All Materials To Disk" width:150 height:45
fn s3d_fn_AddMaterialToList mat =
(
)
fn s3d_fn_DeleteMaterialFromList mat =
(
if not mat.selection.isEmpty do
(
)
)
on s3d_BTN_CreateIDMaterial pressed do
(
tempColorIDMaterial = standardMaterial name:s3d_EDT_ColorIDName.text diffuse:s3d_CPL_ColorID.color
newIDColor = tempColorIDMaterial.name+", "+ s3d_CPL_ColorID.color as string
s3d_LBX_IDMaterialList.items = append(s3d_LBX_IDMaterialList.items) (newIDColor)
for j in selection do
(
j.material = tempColorIDMaterial
)
)
--on s3d_BTN_RemoveIDMaterial pressed do s3d_fn_DeleteMaterialFromList s3d_LBX_IDMaterialList
on s3d_LBX_IDMaterialList selected nameIndex do
(
select (getNodeByName s3d_LBX_IDMaterialList.items[nameIndex])
)
)
createDialog s3d_MATERIALTEST
Here’s another way to try it out. The only difference in both is how the item array of the listbox is filled – one time with the names of the objects, and the other time with the names of their materials.
This works:
ClearListener()
rollout objectKiller "Object Killer"
(
listbox objectToKill "Objects:" items:(for o in objects collect o.name)
on objectToKill selected nameIndex do
(
select (getNodeByName objectToKill.items[nameIndex])
print objectToKill.items[nameIndex]
)
)
createDialog objectKiller--create a dialog from the rolloutParameters
This doesn’t work.
ClearListener()
rollout objectKiller "Object Killer"
(
listbox objectToKill "Objects:" items:(for o in objects collect o.material as string)
on objectToKill selected nameIndex do
(
select (getNodeByName objectToKill.items[nameIndex])
print objectToKill.items[nameIndex]
)
)
createDialog objectKiller--create a dialog from the rolloutParameters
D’oh… Isn’t it nice when you can answer your own questi0n?
Anyway, it was sort of my own problem and a friend of mine pointed me in the right direction:
getNodeByName looks for nodes, and as my materials arent connected to any node they cant find it.
So instead i just took out the whole line, working with listbox.selection now and that works fine.
