[Maxscript] discard array items doesn't work fine

EspiSensei

Hi everyone!

I'm trying to develop a tool which  has 2 arrays (Prueba1 is the main array  and prueba2 contains the words that musn´t appear).  

First erase the " * " character and later through the "FindString" function check if it was a string correct or not. But i have an exception which i don't see right now, this exception is with Prueba 1 ("prueba_emissive_11").

Can you help me with this stupid bug ? :S  jajajaja  thanks! 

prueba1 = #(

"prueba111",

"LA_emissive_prueba1",

"prueba_emissive_11",

"prueba_caliper_garage",

"prueba22",

"car_interior_garage",

"Car_shadow"

)

prueba2 = #(

"*emissive*",

"*_caliper_garage",

"interior_garage",

"*shadow*"

)

fn getNamesOfMeshesThatRequireUV2 = (

local meshesThatRequireUV2 = prueba1 

 

for n in prueba2 do (

local exceptionName = substituteString n "*" "" 

for m in prueba1 do (

local TheName = m

if findstring theName exceptionName != undefined then (

deleteItem meshesThatRequireUV2 (findItem meshesThatRequireUV2 theName)

)

)

)

messagebox (meshesThatRequireUV2 as string)

)

getNamesOfMeshesThatRequireUV2()

This is why side-effects make stuff hard You're iterating over an array and modifying that array at the same time. Either collect a new array as you go instead of deleting from you working set, or iterate backwards (i.e. for i = prueba1.count to 1 by -1 do (local TheName = prueba1[i] ...).

Thank you Swordslayer! i try it! Later i will tell you new!

Swordslayer, i got it!

thanks for all!1 finally I've develop the function this and works!

fn getNamesOfMeshesThatRequireUV2 = (

Local meshesThatRequireUV2 = #()

for i =1 to prueba1.count do (

Local theName = prueba1[i]

Local checked = True

for j=1 to prueba2.count do (

Local exceptionName = substituteString prueba2[j] "*" "" 

Local result = findString theName exceptionName as string 

if findString theName exceptionName != undefined then (

checked = false

)

print (" prueba1 :  "+ (theName) +"   exception!!:  " +(prueba2[j] as string) + "    resultadooo:   "+ result + " ----CHECKED-----   "+ (checked as string))

)

if checked == true then (

append meshesThatRequireUV2 theName

)

)

messagebox (meshesThatRequireUV2 as string)

)
