I think i did things right, then again being new to programming i might have made some silly mistakes too...

I just can't seem to get the custom cursor to work. The cursor image is within the resource files. when i run the program it doesn't even show the cursor, it's just hidden as if i used the dbHideMouse command... which i obviously didn't...

i recall dbp having an issue with the mouse cursor images, something like the index of the image array was off by one because the ide used "count" and the engine uses "index". Not sure if this is a related issue tho

so... Dark GDK inherited the same issue?

Is there any other way to display a custom cursor then?

Make a few different images in a row, and play with the mouse command and sere if ANY of the images show. Then you might find a quirk (Which would break if this is actually a bug and ever fixed) Where you load TWO IMAGES, for your cursor, and the code seems to WORK on Imagwe 2 but actually Image one gets displayed.

I'd load 3 images in a row, and then play with it, make images look like #'s 1,2, and 3 so you know what's going on

Just a guess.

i tried three different images but the result is the same, the cursor disappears completely, i can't even see the default windows cursor. I am thinking out loud here, but what if it's a problem with back/front buffer? Perhaps should i use some code to manipulate the buffer and make the cursor visible?

Went over my head here. I don't know - or even have a guess. I DO KNOW that "GENERALLY" Speaking, in "Windows", that the mouse cursor can be set on a per "window" basis. I haven't done it other than with VB6, however I've seen enough API code to know you can change the "resource" (Same as a loaded image kinda) to control how the mouse looks.

It is also very possible that the way a mouse cursor is handled under DirectX or Specifically handled in DarkGDK/DBPro is way different. It could be like you said a No Z Buffer thingy - a sprite over (on top) everything else.

also - because DarkGDK "hides" the main loop from you - I think you'd have to get fancy by "learning" the HWND for the Game Window and then trying to use the Windows API somehow.

The SIMPLIST solution MIGHT be to simply make your own "Sprite" and Do your own ZBUFFER thing and hide the real mouse cursor - and position the sprite where the mouse cursor should be or where you think it should be from polling the mouse yourself. This needs to be in your main loop to work right - but could be the trick you need to move forward quick rather than writing a ton of tests on various API functions etc.

Good Luck.

well... a tiny step forqward was made today:

The following code is responsible for the custom cursor to appear on the screen, problem is the cursor won't move!

This reminds me of a similar issue i had on CoolBasic where i had to find a work around to have the position of the mouse being followed by the custom cursor... i'll try to look for that thread if i can find it, meanwhile is there something else you guys might know that would help?

mmh... perhaps i should put in the wishlist a working version of dbChangeMouse? Why is it even there if all it does is making the mouse pointer disappear? lol

done!

I figured i needed a loop to keep the custom cursor refreshed so since i had the while loop available i thought i'd put the custom cursor code in there, dbChangeMouse still doesn't work (perhaps it needs other things?) but dbSprite does the trick!

I don't THINK you need the HideMouse INSIDE the loop. I think once ought to do.
