Quite a regular

Hi All,

I'm working on the images for the engine. I can load, display (paste) and delete images.

Here is a small star scroll based on an image that is 256x256 pixels wide. The source code IS NOT optimized. It's only for demo purpose and showing the engine commands set ;)

Now, you also have a logo that use blending for transparency using alpha channel.

Here is the demo source code :
(as easy as basic language, but in C)


#include "AmiDARKEngine.c"

float XPos, YPos;



void DarkLoop( void ){

  DESetDisplayMode( 640, 480, 32 );

  DESetMaximumTextures( 2 );

  DELoadImage( "Images/Space_3-2.mrw", 1 );

  DELoadImage( "Images/logo.mrw", 2 );

  DECls();

  XPos = YPos = 0;

  while( !DELoop() ){

    XPos = XPos - 0.1 ;

    DEPasteImage( 1, XPos, YPos );

    DEPasteImage( 1, XPos + 256, YPos );

    DEPasteImage( 1, XPos + 512, YPos );

    DEPasteImage( 1, XPos + 768, YPos );

    DEPasteImage( 1, XPos, YPos + 256 );

    DEPasteImage( 1, XPos + 256, YPos + 256 );

    DEPasteImage( 1, XPos + 512, YPos + 256 );

    DEPasteImage( 1, XPos + 768, YPos + 256 );



    DEPasteImageEx( 2, 64, 64, 2 );





    if ( XPos < -256 ){

      XPos = XPos + 256;

     }

    DESync();

   }

  DEDeleteImage( 1 );

  DEDeleteImage( 2 );

 }

Does this small sample work on your Amiga with OS4 ?

EDIT : Simply press escape to quit the demo.

Kindest Regards,
Fred

All we have to decide is what to do with the time that is given to us.

Just can't stay away

@freddix

It works but only in the original window size.
Check this picture.
I made the window bigger, but the stars didn't follow.
They keep scrolling in the original window size.

Hi Elwood,
In fact I've not yet defined stretching function that's why when you're resizing the window, the stars keep the same size .. it also show the clipping I've made at the default resolution.
