Object variable issue

I
Not sure if I use the right words for what things are.
I have an object constructed that way:
myvar.h
myvar[i].v
myvar[i].fov

Then I want to save a temporary version of all myvar to be able to recall it later.

To save in temp:
set (myvarTEMP, get(myvar));

then myvar is modified but at some point I want to recall to original myvar so I do:
set (myvar, get(myvarTEMP));

The saving works.
The recall doesn't. In fact it looks like myvarTEMP is in fact a reference to myvar so all the modifications done to myvar were updated for myvarTEMP (bad way to say it as it is a reference I suppose). So when I call back the old values they were actually the mod ones.
I need the temp not to be a reference but a completely independent variable/object.

I tried search and find ways around this.
It feels like some basic thing I don't understand.

Thanks for help anyone.

<action name="checkVartemp" autorun="preinit">    
set(myvar, 00001);    
trace('1: ',get(myvar));    
set(myvarTEMP, get(myvar));    
trace('2: ',get(myvar),' temp: ',get(myvarTEMP));    
set(myvar, 00002);    
trace('3: ',get(myvar));    
set(myvar, get(myvarTEMP));    
trace('4: ',get(myvar));  
</action>



and I have this data:

Quellcode

INFO: 1: 00001  
INFO: 2: 00001 temp: 00001

Hi Piotr
Yes it works with a simple variable. But it seems that if the variable is an array, then a copy of it is a reference...
I can't rechceck right now sorry. Later tonight.

Hi

copy(myvarTEMP, myvar); == set(myvarTEMP, get(myvar)); - The effect is the same ;-)
