Could anyone supply me with the syntax for the array.swap command when handling multidimensional arrays? I've searched the help but the only reference to it I can find is

Quote: "Misc
There are some additional array commands that don't fit in the above categories, they are .swap(index1,index2) to swap two elements in an array (including types and multidimenional arrays) and .reverse() to reverse the elements in an array."


Using a 2-dimensional array of a type, I'm trying to swap two elements, e.g.

swap() can only swap within the same dimension, so you could swap [1,2] and [1,3] by doing giSpriteTiles[1].swap(2,3) or you could swap the arrays [1] and [2] by doing giSpriteTiles.swap(1,2). To do what you want in your example you would have to use the normal method of saving one in a temp variable and switch them manually.

its only possible if Paul overload with swap([a1,a2],[b1,b2]) ...
if type is same it should be possible.

@Paul
cut,copy,paste would be a nice to have in array.
array[1,2].cut
array[2,3].paste

Thanks Markus but that was the first command I tried; no joy.

Markus, absolutely - that's a good idea.

Just have an index array and swap the indices. Never swap the data unless you are absolutely forced to, which in my experience is never.

@JimHawkins , Paul
if we could use by reference also in array it can be fast
swapping data blocks.

function MySwap(ref a[,] as ttype)

//its early in this morning here
local t as ttype
t = ref a[1,2]
a[1,2] = ref a[2,3]
a[2,3] = ref t

That's a better way than moving data!

Not hijacking this thread, just didn't want to start a new post for a simple question:

in AGK2, how do you delete an array? In AGK1, you could use undim, but it seems that the DIM commands are depreciated.

If I have arrays within arrays, e.g. ARRAY[x].subarray[y].something, is there a way to delete ARRAY, without any memory leaks?

Thanks,

James

Only Paul can really answer this.

In an ideal world these would be objects which could be created and destroyed. Maybe that's possible, but I think not.

@Jambo B
i know only this way.

Quote: "
a as integer[100,50]
a[0].length=0
//a.length=0
do
print(a.length)
print(a[0].length)
print(a[1].length)
if GetPointerPressed() then exit
sync()
loop
end
"
