I'm still making my level editor, and I want it to save to an array. I'm using the regular Array object (because I want to) and want to save three values to the same cell. To do this, I'm going to combine them into one string and save that. But, I have two questions about that:
1) Because I have three values with maximums of 99, 32, and 4, and minimums of 0, I need to convert them into strings of two characters each. Is there an easier way to do this than to create different events for each conversion? Please remember to show your work and answer in complete sentences.
2) Ignoring Z layers, can you save both values and strings to any cell? Please answer in complete sentences.
BONUS: Can you detect the number of buttons on a mouse? Please remember to show your work and answer in complete sentences.
This quiz has a maximum of 10 points. The bonus is worth 2 points. Partial credit will be awarded for questions.

Firstly, you may find it interesting to look at the TileWidget I made a while back.
It's a simple tile based level editor/loader, but it doesn't actually use the array object - instead it simulates a complete 3-dimensional array in a single text string. It actually saves the level as ascii text, using an edit box object.
Anyway, it uses all the tricks you need, and I think it's vaguely commented.

Having said that, is it not going to be easier for you to just use more Z layers?
1.)
Not sure what you mean exactly. You could use the StringParser extension, or could do it this way...
EXAMPLE
Create a String Containing 3 Values:
Right$( "0"+ Value_A, 2 ) + Right$( "0"+ Value_B, 2 ) + Right$( "0"+ Value_C, 2 )
Retrieve Values from String:
Value_A = Left$( String, 2 )
Value_B = Mid$( String, 2, 2 )
Value_C = Right$( String, 2 )
2.)
Obviously a string can hold numbers and text, so I presume you are having a problem with storing several sub-strings of unknown length, in a single string (ie. knowing where one string ends and the next begins)?
The easiest way is probably to use the StringParser extension. Separate each substring with a delimiter.
EXAMPLE
Create a String Containing 3 Values/Strings:
String_A + "|" + Str$( Value_A ) + "|" + String_B
Retrieve Values from String:
String_A = listGetAt$( "String Parser", 0 )
Value_A = Val( listGetAt$( "String Parser", 1 ))
String_B = listGetAt$( "String Parser", 2 )
Another way would be to store the length/starting-point of each substring in the first few characters, and then look up the corresponding portion of text - I won't explain in depth, as I think the substring method is easier anyway.
3.)
My gut feeling is "no", but I'm not sure.

Sketchy hit the nail on the head. Exactly what I thought.
1)strings can hold values, so differentiating them is kinda useless.
2)parse strings with deliminator
3)no
thinking is like pong, it's easy, but you miss sometimes.

First example should read:
Create a String Containing 3 Values:
Right$( "0"+ Str$( Value_A ), 2 ) + Right$( "0"+ Str$( Value_B ), 2 ) + Right$( "0"+ Str$( Value_C ), 2 )
You probably could have figured that out anyway...

Sketchy got 10/10 points, but he didn't get the bonus question.
I now know how to use the String Parser 2 object! Yay! I got that to work.
Um... is there any way to detect when a new array is opened?
