I don't want to but reading all the reply's it shows you have to know a lot more than only "a pointer is a variable holding an address"..
You basically have to know the inner workings of the programming language you use too and that's not like a quick read trough the manual if you ask me :(

Small ...

I see, that's why it's put inside a struct as a normal variable :)

So structure unions always pick the biggest value to make space for, even if you just want to store for example a bite?

Maybe I'm just better of not using pointers and memory allocation to store variables.. I'm looking for a simple ...

Wow, a lot of reply's, good! :p

So it's not as simple as allocating 4 (or 8) bites to a pointer for an integer and afterwards reallocating to the string size?

Also, using structure union doesn't allow strings as types and if you use structure union it's gonna use more memory than needed: "always ...

I have a few questions on pointers as I'm trying to learn them bit by bit.
To do so while simultaneously solving a little problem I encounter now and then I started a little learning project:

"Use pointers to store variables as variants"

; var = 10 (vbscript syntax used as example)

*variant ...

Nice ideas! Thanks everyone :)
I'm gonna check those out this weekend!

how would you guys go about clicking on a non rectangular object in a 2D game?
let's say I want the mouse arrow to change only when I hover above a pixel of a partially transparant image..

2D array with pixel coordinates?
Getting the pixel color of a separate bitmap that's black and white? (no idea ...

I mean I don't use #PB_any :)
and I reassign the map()\image part when I reload an image but in the helpfile it says unloading is not needed (automatically)

- An object that is associated with an index is automatically freed when reusing that index.

so replacing an image e.g. image 0 to another .bmp file wil not create a memory leak if I understand correctly?

I don't use #PB_Any in my original code, the index is stored in the map to change the image ...

So an image handle can randomly change in memory?
I thought handles were static? Sort of a constant so to, speak until released / altered?

Or do you mean something else?

But in my program it always returns the windows handle as a result, without imageid()..

debug LoadImage(0, "a.bmp")
debug imageID(0)

The way I load and use the images 'imageID()' is only an unnecessary extra step because it is stored in the map anyway..
I only need to display the images on a GUI ...

Woops, okay, first things first..

"Are you sure (as a start) that the next line did not rise any error?"

Sorry about my first code sample here,
it was very late and I made a quick little version of my code for this post to explain the problem.
I misplaced the '()' on the new map, and mistakenly ...

Structure newstruc
info.s
image.i ; save id hande
EndStructure

; Global NewMap imag().newstruc EDIT: made a mistake here while making this post
Global NewMap imag.newstruc()

Procedure load_imgs(name.s)
imag("name")\info = "test"
imag()\image = LoadImage(name + ".bmp")
imag(name + "2")\info ...

Nice, thanks :)
Didn't see that in the helpfile first for some reason :shock:

Okay, so how do you know it 'auto unloads' the file actually?
The help file is very limited about such things...

Hi :)

Quick question(s) about the inner workings of the sound system:

If I load a sound and want to replace/reload it afterwards while the program is running, do I first need to unload e.g. sound '0' to replace it?

LoadSound(0, "a.wav")
LoadSound(0, "b.wav")

I also wonder if continuously ...
