Remove the quotes marks from a string how.?

[Eric-Harvey]

Not sure if this will help but you can evaluate a string as though it were a statement by using the execute command.

thanls Eric for your replay,

i did try the execute and it works on a single item but not in an array. see the two samples.

this works.

rollout test "test" width:300
(
edittext edi_Custom "mat." fieldWidth:165 align:#left across:2
spinner spn_Custom "%" range:[-1000,1000,0] align:#right
button go "Go"

on test open do
(
edi_Custom.text = "specularLevel"
)

on go pressed do
(
--format "what:% value:% \n" edi_Custom.text spn_Custom.value
str = "meditMaterials[1]." + edi_Custom.text + "=" + spn_Custom.value as string
execute str
)
)
createdialog test

this dosen't

rollout test "test" width:300
(
edittext edi_Custom "mat." fieldWidth:165 align:#left across:2
spinner spn_Custom "%" range:[-1000,1000,0] align:#right
button go "Go"

on test open do
(
edi_Custom.text = "specularLevel"
)

on go pressed do
(
--format "what:% value:% \n" edi_Custom.text spn_Custom.value
TheMaterials = sceneMaterials
numOfMatInScene = TheMaterials.count
for i = 1 to numOfMatInScene do
(
--print TheMaterials[i]
str = TheMaterials[i] as string + "." + edi_Custom.text + "=" + spn_Custom.value as string
execute str
--print str
)
)
)
createdialog test

In order to troubleshoot your code, I recommend you try to do the same exact execute command with each version (the single versus the array). You're doing enough different stuff in the one that's not working that it would be worth your while to mimick the one that IS working first.

[Eric-Harvey]

Ok I have broken down the issue here. basically when you execute TheMaterials[i] it returns the name and type of that material instead of an index of the material. So the best soultion is to use scenematerials[i] directly to get your materials. Also you have to include the index number seperately and include the square bracke s in the surrounding strings. Im not sure if this makes sense, but here is the code that works.

rollout test "test" width:300
(
edittext edi_Custom "mat." fieldWidth:165 align:#left across:2
spinner spn_Custom "%" range:[-1000,1000,0] align:#right
button go "Go"

on test open do
(
edi_Custom.text = "specularLevel"
)

on go pressed do
(
--format "what:% value:% \n" edi_Custom.text spn_Custom.value
for i = 1 to sceneMaterials.count do
(
--print TheMaterials[i]
str = "sceneMaterials["+ (i as string) + "]." + edi_Custom.text + "=" + spn_Custom.value as string
execute str
--print str
)
)
)
createdialog test

Eric,

Cool, that did the trick! thanks a lot.

This is probably a stupid statement, but couldn't you use filterstring??
sText = “mat.texmap_reflection.ior = 0”
aText = filterString sText "/"" -- #("/“", mat.texmap_reflection.ior = 0, "/"”)

sValue = aText[2] //mat.texmap_reflection.ior = 0

Please delete, double post

[RobGalanakis]

Rusty, isn't the issue that even with filtering a string, you still have to execute it... the "'s aren't the problem, the fact that it is a string is, which is taken care of by executing it.

The thread title is not really what the OP wanted to do...
