Creating new arrays

[EthernautParticipant]

Ok, really basic. How do you create a new array and add all values at once (without iterating)?

In Monkey1 it used to be:

1С (Запрос)

Local frames := [0,1,2,3,4]

1 2	Local frames := [0,1,2,3,4]

In Monkey2 that doesn’t work. I also tried this:

1С (Запрос)

Local frames := New Int[5] frames = [0,1,2,3,4]

1 2	Local frames := New Int[5] frames = [0,1,2,3,4]

Doesn’t work either.

Help!

I really love (in Bmax) this

Monkey

<del>Local def$[]="alfa,beta,gamma".Split(",")</del>

1	<del>Local def$[]="alfa,beta,gamma".Split(",")</del>

I don’t know if MX2CC can ‘understand’ this type of situation or needs a ‘creation step’ before (I mean how many items can the array store initially).

At least something to ‘feed’ the array in some way could be handy

Monkey

<del>Local def:=New String[10] def=Array("alfa,beta,gamma".Split(",")) </del>

1 2 3

<del>Local def:=New String[10] def=Array("alfa,beta,gamma".Split(",")) </del>

 

No matter, I found the solution on the MonkeyX forum (referring at a blog post here :D)!

 

In any case I found that this works

Monkey

#Import "<std>" Using std.. Function Main() Local w:=New Int[](1,2,3) Print w[0]+" - "+w[1] End #Import "<std>" Using std.. Function Main() Local sa:=New String[]("alfa","beta") Print sa[0]+"-"+sa[1] End

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

#Import "<std>" Using std.. Function Main() Local w:=New Int[](1,2,3) Print w[0]+" - "+w[1] End   #Import "<std>" Using std.. Function Main() Local sa:=New String[]("alfa","beta") Print sa[0]+"-"+sa[1] End

So Int[] and String[] can be ‘instanced & resized’ automatically depending on the items passed

This one doesn’t work (

Monkey

#Import "<std>" Using std.. Function Main() Local sa:=New String[]("alfa,beta".Split(",")) Print sa[0]+"-"+sa[1] End

1 2 3 4 5 6 7 8 9 10

#Import "<std>" Using std.. Function Main() Local sa:=New String[]("alfa,beta".Split(",")) Print sa[0]+"-"+sa[1] End

I need to specify the size of the array

Monkey

#Import "<std>" Using std.. Function Main() Local sa:=New String[2] sa="alfa,beta".Split(",") Print sa[0]+"-"+sa[1] End

1 2 3 4 5 6 7 8 9 10 11

#Import "<std>" Using std.. Function Main() Local sa:=New String[2] sa="alfa,beta".Split(",") Print sa[0]+"-"+sa[1] End

Maybe (probably!) I missed something obvious in the syntax.

This works:

Monkey

Local sa:= "alfa,beta,gamma,delta".Split(",") For Local n := Eachin sa Print n Next

1 2 3 4

Local sa:= "alfa,beta,gamma,delta".Split(",") For Local n := Eachin sa     Print n Next

I think String.Split() already returns a new array, so you don’t have to use “New” or specify the size before calling it!

And yes, I posted in the Monkey-X forums as well, but I like posting here since it can be useful to people starting on Monkey 2.

Cheers!

Thanks – I know I’ve did something wrong in the syntax!

 

I think I’ll add these informations directly in the modules section/monkey-types/array http://monkey2.monkey-x.com/modules-reference/

I missed this one before:

Monkey

Local tmp:=New Int[]( 1,2,3,4 )

1	Local tmp:=New Int[]( 1,2,3,4 )

Found it again here

OK, after trying & searching I need help.

How we can ‘resize’ an array?

Monkey

Namespace myapp #Import "<std>" Using std.. Function Main() Local nn:Float[] Print "GetSize: "+nn.GetSize(0) 'there's nothing! OK Print "Length : "+nn.Length nn=nn.Slice(0,10) 'should 'resize' to 10 items??? ' nn[0]=1.0 'of course, array out of index... Print "GetSize: "+nn.GetSize(0) 'same, 0 Print "Length : "+nn.Length End

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

Namespace myapp   #Import "<std>"   Using std..   Function Main()   Local nn:Float[] Print "GetSize: "+nn.GetSize(0) 'there's nothing! OK Print "Length : "+nn.Length nn=nn.Slice(0,10) 'should 'resize' to 10 items??? ' nn[0]=1.0 'of course, array out of index... Print "GetSize: "+nn.GetSize(0) 'same, 0 Print "Length : "+nn.Length End

or

I think you need to do a CopyTo:
> Method CopyTo:Void( dstArray:T[], srcOffset:Int, dstOffset:Int, count:Int )

I believe you have to create a temporary variable array of the desired length as I don’t see any other way.

or you can simply resize an empty array:
> nn = New Float[10]

Slice() can shrink an array but it can’t grow it – I still need to add a proper Resize().

OK, thanks
