Setting Variables programatically?

[Baaleos]

Is it possible to set a variable without having coded for that specific variable to be changed?

eg

If I look at an object/entity
Speak the words

Set VARNAME = VARVALUE (Where VARNAME is the name of the variable, and VARVALUE = the variable value I wish to change it to)

And then VARVALUE replaces the value of VARNAME.

Can this be done?

Are variables on entities exposed as NetworkedStrings/Int's etc

Can the SetNetworkedString & SetNetworkedInt functions change variables?

I'd like to be able to programatically change a variable value from ingame.

Or even another example

[LUA]

local ent = SomeEntity
local varTable = { "first","second","third"}

for k, v in pairs(varTable) do
ent.v = someValue
end

[/LUA]

Is the above do-able?

eg - Taking a string, and using it as a reference to a variable?

Yes.

[lua]local ent = SomeEntity
local key = "name"
ent[key] = someValue[/lua]

Your second example has a small mistake though. Using ent.v would try to access the key "v", what you want in ent[v], which would access the correct one.

Thanks raBBish,
Thats great.

I run a server with the Networked Personal Fairies, and I plan on introducing a chat command that allows fairies to modify variables on other entities.

Sort of like turning them into a Debug Tool, or a cheat tool. hehe.

I have plans on making them capable of modifying the Carters Pack Dakara Superweapon, to target custom entity classes.

[LUA]

ent = TheDakaraSuperWeapon
command = "insert" -- Used to insert into a table, also identifies that the variable we are modifying is a table
varName = "Targets"

argVal = "ZPM"

(chat command would be: *FairyName* insert ZPM into Targets ) * While looking at the entity

table.insert(ent[varName],argVal) -- Inserts ZPM into the targets list
