DeleteVariables and Arrays.

$Amigos[0] = "John";
DeleteVariables("$Amigos[0]");
echo($Amigos[0]);I'm creating documentation to put on my website about the collections in Torque 3D. According collections I have understood not really because they are simple variables, now my question is whether they are variables that the code above does not work, and I think that somewhere in that global variable remains and is not deleted.

But then a collection is deleted touches make it single or manually?Edit: Ok I get it, my English is lousy, I put this in and it works.
DeleteVariables("$Amigos0");

Deletes all variables, including those with [ ] to simulate collections?

Now the question if I do this.DeleteVariables("*");Deletes all variables, including those with [ ] to simulate collections?

So really you should use
and this should not do anything:

Here's the whole console function (from source/console/consoleFunctions.cpp at about line 2499):DefineEngineFunction( deleteVariables, void, ( const char* pattern ),,
"Undefine all global variables matching the given name @a pattern.n"
"@param pattern A global variable name pattern. Must begin with '$'.n"
"@tsexamplen"
"// Define a global variable in the "My" namespace.n"
"$My::Variable = "value";nn"
"// Undefine all variable in the "My" namespace.n"
"deleteVariables( "$My::*" );n"
"@endtsexamplenn"
"@see strIsMatchExprn"
"@ingroup Scripting" )
{
gEvalState.globalVars.deleteVariables( pattern );
}So really you should use
deleteVariables("$Amigos");and this should not do anything:
deleteVariables("*"); // does not contain "$"
// and no legal variable name contains "*"

Edit:
and if the collections or variables are not stuck in name spaces, touches manually delete?, calling them by name?
Or I can use this?

Ok I have understood the asterisk (*) is to eliminate multiple variables that are under a single name space, right?DeleteVariables("$Recursos::*");Edit:

Or I can use this?
DeleteVariables("$*");

Actually because FindMatch::isMatch() is used by Dictionary::deleteVariables() then Yue's following code will destroy all global variables:DeleteVariables("*");

Which I highly recommend not doing as some $globals are used between the engine and scripting layer :P

Perhaps we should catch that and disallow it.

Ooooh - lol - that's what I get for posting while doing seven other things... I should have read that more closely. So yeah, don't deleteVariables("*")....Perhaps we should catch that and disallow it.

[] is an appending operator in TS for a more of a way to create a dynamic variable name on the fly (dunno if that's a good way to put it or not) and not necessary a true "array"
