I do have a way to do this, but it isnt very good way, as example:

mytable = {
          ["variable"] = 1
                }

mystring="variable"

mytable[mystring] = 2

I can do it this way, but what i would like to do, is to be like this:

Code: Select all

variable = 1
mystring = "variable"
mystring = 2

and variable value changes into 2.

What I am after with this is that perhaps I would like to debug my program, and it could be handy that i could in middle of program push some predefined button, as example "c", and it would ask me to give me both variables name, and its new value. Then i would simply put for example: "Speed" and "10", and after this, program would execute "Speed = 10", and i could see if bug occurs now or not.

The beginning version is one possiblity, but it means that all my variables should then reside in one and same table. What I would like to have, is to still have the freedom of using my own variables like i have been doing before, yet be able to change their values using Strings to tell what variable i want to be changed.

Is this possible, and how?

It's some time I'm thinking how to implement an interactive mode like the console mode we see in some games, unfortunatly actually my free time is almost zero

Anyway, unless Andreas have a custom command like the one used for the constants (GetConstant) the only way is to store all variables in a table. I usually do this for my app and libraries.
For the app I use a table named "app" for all variables and tables.

@Andreas
It could be difficult to implement a couple of commands like:
value = GetVariable(variable_name)
SetVariable(variable_name, value)

Actually, it's already possible by peeking/poking into an invisible table that goes by the name of "_G". All globals are stored in this table, so you could just do something like this:

Code: Select all

Function p_SetVar(name$, v)
	RawSet(_G, name$, v)
EndFunction

Function p_GetVar(name$)
	Return(RawGet(_G, name$))
EndFunction

testvar = 6
p_SetVar("testvar", 7)
DebugPrint(p_GetVar("testvar"), testvar)

Output is:

Code: Select all

7 7

Be sure to use only variable names in lower case. It won't work with mixed case or upper case variable names.

That's wonderful to know! Thank you for the info

I was actually myself thinking that it might be possible to do somehow through that global list, just couldnt figure out myself how to do it.

Thanks a lot! This is very helpful option.
