Array as a parameter?

[Torahteen]

I've done this before, but it's not working this time. Here is my error:

Code:

game.bi(15) : error 57: Illegal specification, at parameter 1: list
Declare Sub EraseBricks(list() As PointType)

[stylin]

Are you sure PointType has been declared before this function declaration?

[Torahteen]

Woops :oops:. Now that i've fixed that... Are you not allowed to DIMension an array (more specifically a dynamic array) inside a SUB or Function?

[stylin]

You sure can:

Code:

sub foo(dynamicSize as integer)

    '/ declare fixed-size array
    const staticSize as integer = 420
    dim as integer staticBar(staticSize)
    
    '/ declare variable-size array
    dim as integer bar(dynamicSize)

end sub

staticSize must be a compile-time constant, of course (const, enum or literal).

since .16, you can also do this

Code:

sub foo()

  dim as integer ary()

  ...

  redim ary( 7162 )

  ...

end sub

before you could not specify "dimensionless" arrays inside of sub/funcs

Don't forget the arrays DIMed in subs/functions are created on the stack, and the stack is 1Mb by default.
If you need a bigger array either you make it shared, increase the stack size or use direct memory allocation.

You can also make a memory block act like an array.

Code:

Declare Function newInt(size as uinteger) as integer ptr
Declare Sub delete(pointr as integer ptr)
dim myArray as integer ptr
myArray = newInt(200)

for i = 0 to 200
   myArray[i] = RND * 1000
next

delete myArray

Function newInt(size as uinteger) as integer ptr
   return allocate(size * 4)
End Function

Sub delete(pointr as integer ptr)
   deallocate pointr
End Sub

Ah, dynamic allocation

Be careful using literals for datatype size like that. You should always prefer sizeof or len. I prefer sizeof myself, simply because it seems more compile-time to me, as len is also a run-time function. But they both give compile-time results for var and datatype sizes.
