Can someone explain the expression editor to me please

[Simflare]

Hi, I have no idea what most of the functions do on the expression editor, and I need to start understanding them (and I couldn't find explanations in the help files). Is there somewhere that explains what all of the functions mean, especially ones like Left$, Right$ and Mid$? I'm assuming they're to do with string, but don't know what they do and how to use them. It'd be great if someone could fill the following table with brief explanations:

Left$: <what it is and what it does>
Mid$: <As Above>
Right$ : <" ", etc>
Len:
Val:
Str$
Hex$:
Mod:
Misc - Power:
Misc - Bit-wise AND:
Misc - Bit-wise OR:
Misc - Bit-wise XOR:

Thank you in advance

Left$ will allow you to take only a certain number of characters in a string, starting from the left and going as many characters as are listed after the comma
If I have a string titled Name which is "Rubes"
Left$( Name,3 ) would be "Rub"

Right$ works the same way but working from the right side of the string
Right$( Name,3 ) would be "bes"

Mid$ allows you to grab in the middle of the string, here we have two values to set, where to start grabbing and how many characters to grab
Mid$( Name,2, 2) would be "ub" (Start at the second character in the string and grab two characters)

Len will return the total number of characters in a string

Val will allow you to take a string that is numbers, and convert it to a numerical value that can be manipulated with math

Str$ will allow you to take a number and convert it into a string

For the string functions, here is an in-depth example/tutorial I put together:

The help file has explanations for these, press the help button from the expression edit.

I did look at the help file, but could only find a general overview of the expression editor, not explanations for each individual function.

Pineapple, your tutorial is excellent!

Rubes, thank you for those very helpful explanations. It sounds like the mid$ function is going to be very useful to me indeed!

Cheers everyone!

SimFlare, incase you still wanted a overview of each function, I made this tutorial for MMF2. Though it is for MMF2, it covers a great portion of the general Expresssion Editor functions. In the upcoming future, I will be releasing one for Clickteam Fusion & all of its default actions/conditions/expressions

Thanks, it looks useful
