Hey there
(go to the bottom for the express description on the prob)
I'm trying to make a simple nonogram game and well i'm having some problems regarding the number system on the sides. If you are not familiar with the type of game you can see it here : http://en.wikipedia.org/wiki/Picross
The problem is adding the numbers together.
For example if the blocks are "0 0 1 1 0 1 0 1 1 1" it should read out "2 1 3".
I'm using a array object to manage the x,y and i have variable on every brick that states where it is (x.y), it also has a variable that states if its selected or not.
So basicly i'm asking for a help on what method i should use to get it to work.
I am totally going nuts on trying random methods out of my head.
************
I have a textbox that says "0 0 1 1 0 1 0 1 1 1" and i want another textbox to calculate from that another string that says "2 1 3"
************
I would appreciate any comments on this matter.
Thanks

I think this should work as a solution to the "express" version of your problem, although I don't have MMF on this computer, so I can't check it.
+ whenever...
-> start Fastloop "Check", Len( String_In )+1 times
+ on Fastloop "Check"
+ Mid$( String_In, LoopIndex("Check"), 1) = 1
-> set Flag_0 to ON
-> add 1 to Counter
+ on Fastloop "Check"
+ Mid$( String_In, LoopIndex("Check"), 1) = 0
+ Flag_0 is ON
-> set String_Out to String_Out + " " + Str$( Counter )
-> set Counter to 0
-> set Flag_0 to OFF
However, it seems like extra work generating a string from the array, and then another string from that - you could do basically the same thing without the intermediate string. I don't have time to work it out now though

Hmmm.. ok
I dont seem to get it to work right...
If for example i have "1 1 0 1 1 0 0" i get "2 2" but if the ending has a 1 then it doesnt work.
"1 1 0 1 1 0 1 1" gives me "2 2".

Sorry - I can see why that would be.
Try replacing this:
+ Mid$( String_In, LoopIndex("Check"), 1) = 0
...with this:
+ Mid$( String_In, LoopIndex("Check"), 1) <> 1
I'm was thinking that retrieving the 11th character of a 10 character long string would return "0", but of course it will return "".

Under Special[the computer icon]->Strings
But there are shortcut buttons in the expression editor for some of them.
They're labelled; Left$, Mid$, Right$ Len and Str$

From the MMF2 help file:
The Special Object - Expressions
Strings
Extract left sub-string extracts a sub-string from the given string, starting on the left. Example, LEFT$("Hello", 3) will return "Hel".
Extract right sub-string extracts a sub-string from the given string, starting on the right. Example, RIGHT$("Hello", 3) will return "llo".
Extract middle sub-string extracts a sub string starting at a given position. Example, MID$("Hello", 1, 3) will return "ell".
Length of string returns the number of characters in the given string. Example, LEN("Hello") returns 5
New Line returns a string with new line control characters. The text after these control characters is displayed on the next screen line. Example, "Line 1" + NewLine$ + "Line 2".
Convert String to Lower case returns a string with lowercase characters.
Convert String to Upper case returns a string with uppercase characters.
Find String in String returns the 0-based index of a sub-string in the string. Parameters = string to look into, sub-string to look for and index of the first character to start the search from. Returns -1 if the sub-string is not found in the string.
Find String in String backward returns the 0-based index of a sub-string in the string, from the end of the string. Parameters = string to look into, sub-string to look for and index of the last character to start the search from. Returns -1 if the sub-string is not found in the string.
