set (and get) array elements

Hi to all

I'm trying to set two arrays, that they're going to be read next.

Quellcode

 
1
2
3
4
5
6
7
8
9
10

for(set(i,0), i LT hotspot.count, inc(i),
		
			add(risulta, hotspot[get(i)].ath, 10);
			set(listR[get(i)],get(risulta));
   		
			set(listName[get(i)], get(hotspot[get(i)].name));
//to test trace the hotspot array and new array created -> ok
			trace(hotspot[get(i)].name, " - ", listName[get(i)], " - ",listR[get(i)]);
	
	);


but, trying to read the new array it's seem that the overall array is only the last one set eg:

Quellcode

 
1
2
3
4
5
6
7

trace(listName[0])
trace(listName[1])
trace(listName[2])
...
trace(listName[N]) 

--> they're the same, ie the last value set


Perhaps I'm not able to manage properly the arrays... *cry*

Any kind of help... *g*

Regards...

Hi,

the krpano arrays are always 'arrays of objects' - where each array item is always a special object which has name and index properties - 'arrays of values' are not possible.

That means if you want to set some array item content, you need to set that to a property,
e.g.
set(listName[get(i)].hs, get(hotspot[get(i)].name));
...
trace(listName[0].hs);
trace(listName[1].hs);

For more details about krpano arrays, please also see here:

Best regards,
Klaus

Hi !
I'm experiencing a destabilizing behaviour with arrays.
I want a global array to store data. In a high-level action, I ask for array creation as documented:

Quellcode

 
1

def(miaou, array);

Then I start using it:

Quellcode

 
1

set( miaou[0].stuff, "meow" );

But this tells me :

Zitat

WARNING: set miaou[0].stuff=meow - miaou is not an array!
... WHY ?!?
If I don't use DEF(), it works... ^_^ But I don't really like using data I don't initialize...
Pleaaaase, help ! :D

Hi,

by using:

Quellcode

 
1

def(miaou, array);
you're defining a special 'value-array':
https://krpano.com/docu/actions/#valuearrays

Such arrays can directly contain values, not objects like the normal arrays.
Add/set a value this way:

Quellcode

 
1
2
3

def(miaou, array);
set(miaou[0], "meow");
debugvar(miaou);


For 'normal' arrays just use the set, then the array will be created automatically:

Quellcode

 
1
2

set(miaou[0].stuff, "meow" );
debugvar(miaou);


See also here for more:
https://krpano.com/docu/actions/#arrays

But if you want to explicitly create/define the array the createarray function can be used:
https://krpano.com/docu/plugininterface/#createarray
E.g.

Quellcode

 
1
2
3

createarray(miaou);
set(miaou[0].stuff, "meow" );
debugvar(miaou);


Best regards,
Klaus
