Hi,

I have an array defined as follows:

dim TwinTriangle[8] as integer

According to the documentation at http://www.appgamekit.com/documentation/guides/12_array_changes.htm

I should be able to define an array as follows:

TwinTriangle as integer[8]

It doesn't work!

Is this a known problem or am I doing something wrong?

The new nomenclature for defining arrays changed in AppGameKit V2, the recommendation is to not use DIM in that version, although both are supported.

I am able to correctly define



or simply



If I use the same in AppGameKit V1, then it is not supported and you will see an error something like (Variable declared using unknown type)

Therefore continue using DIM in AppGameKit V1

Kind Regards
Jason

AGK2 Only:
----------------------
"To maintain backwards compatibility arrays can still be defined with DIM, but version 2 introduces a new method of defining arrays that will become particularly important when defining them in types. Note that both DIM arrays and new style arrays perform exactly the same after they are declared so any functions mentioned here will also work on DIM arrays. The new method is mainly for consistency."
---------------------

You have to use the new method when putting an array in a type.

It is fine to create an array as:
TwinTriangle as integer[8]

Works fine here in V2.

Isn't this an implicit definition?

TwinTriangle is an integer array of length 8.

In V2 you can define an empty array like this:
TwinTriangle as integer[]

or even:
global TwinTriangle as meType[]

...for UDT arrays.

When you say it doesn't work what exactly do you mean? I can compile this just fine.

Further to my previous post:

I am using:
AGK IDE 2.0.10 Built on Dec 4 2014


The code is below. I have commented out the DIM statement that worked.

The array definition without the DIM does not work, the comment is that the array is not defined.

Any more suggestions?

//dim TwinTriangle[8] as integer
TwinTriangle as integer[8]
fillTwinTriangle()

function fillTwinTriangle()
TwinTriangle[0] = 7:TwinTriangle[1] = 15:TwinTriangle[2] = 16:TwinTriangle[3] = 17:TwinTriangle[4] = 24:TwinTriangle[5] = 25:TwinTriangle[6] = 26:TwinTriangle[7] = 27
endfunction

tables.agc:441: error: "twintriangle" has not been defined

Try adding Global to the front, this line works OK for me in my code, using the same AppGameKit V2 build:

global gBox as tBox[3]

and an example of the array used in a function elsewhere:

function TriggerHighlight(index)

colour = gBox[index].multiplier
...


[EDIT]
DIM is always global, wherever you define it. Are you declaring this array in a function? If so, it is local unless you specify otherwise, with the new syntax.

Hi BatVink,

Thanks for the suggestion.

It works if I add Global ahead of the array definition.

Someone needs to update the documentation in this regard.

Thanks

why are you trying to add as integer to it?

dim TwinTriangle[8]

thats it and it will be integer values and global.

and if you want floats?

dim twintriangle#[8]

you do not need to define as integer or as float with dimmed arrays.
