Hi,

Working on the word dictionary lookup.
Lets say I have the following TXT file:
______________________________________________________
aaas
aaal
aaa
aaberg
aachen
______________________________________________________

If I use the following code:

+ Code Snippet

oneWordIndex as integer
oneWordIndex = FindString( DictionaryString[0], "aaa", 1, 1 )
CreateAndInitializeOutlinedText(TRUE, CurrentMinTextIndex, str(oneWordIndex), 999, 20, 255, 255, 255, 255, 0, 0, 0, 1, (ScreenWidth/2)-150, ScreenHeight/2, 0)

it won't work correctly because "aaas" contains "aaa"...

How would I properly read one string line from a MemBock?
Hope someone can help, have much more work to do on this game soon!

Some ideas:

You could ensure your dictionary is ordered correctly... shorter words first then your existing code would work ok.

Alternatively - You could search for oneWordIndex = FindString( DictionaryString[0], "aaa" + "\n", 1, 1 )
("\n" is added above so it checks that the word ends)
You may need to use "\r" depending on what system you created the text file

Otherwise, you could write a Findstring alternative that compares letters and also checks for a or line return at the end

Also check out....

and the GetStringToken2 as these do something similar to what your after!!

or

findstring$="aaa"

if ( len( findstring$ ) = len(dictionarystring[0]) and (mid(dictionarystring [0],1,len(findstring)) = findstring$)
// Found
else
// Move to check the next word
endif

Thanks puzzler2018,

I got it all working now, but will revisit it before official Beta1 release to optimize.
Thanks again for your help with this project...

Isn't there a newline character after each word? If reading the text file into a memblock keeps those, you could add that to your search term.

oneWordIndex = FindString( DictionaryString[0], "aaa"+chr(10), 1, 1 )

Great tip. as long as the FindString command in itself is really fast - cause just tried and its agonizingly slow searching a full length of words using my own version of a word find

Suppose this is all about optimisation now

Its the same suggestion I posted above in the second post. lol

chr(10) = "\n" - either way its checking for the newline character

You could optimise by splitting the dictionary up further, so its not having to findstring in such large chunks. Split A into AA, AB, AC,AD words and so the search is on a smaller string but this would require you to split up your dictionary string into substrings.
