In the code you originally posted, the call to VDP_setPlanSize sets the background plane size to 32x32 tiles. At this setting, it's too small to fit your 680 pixel image. You'd have to set the plane size to 128x32 which would give you a maximum size of 1024 x 256. If your image fits into that, then ...

Hi,

I made the changes with & 31 and & 127. My background image is 680 px wide and with the "& 127" modification I can't display the entire image. So maybe I need to charge another background image (maybe is less memory consuming) when the posx is bigger than 128 tiles each time or I need to place ...

Hi,

I've been trying to display correctly the background with your suggestions. I made some advance but seems that I need to reset something when the background reaches the width of the plan, because its loading the background but one tile below position 0 each time. Here's is the code:

#include ...

Thank you!

I see that VDP_setPlanSize can be used to change the background size.

So if I understand, I can make a bigger background image and by code I need to update the plane when the a full chunk (maybe a 32 tile width chunk) of that image has been scrolled. Maybe using u16 VDP_drawImageEx and ...

Hi!

I was playing with the sprite demo included with the sgdk download. I was trying to make the "level" bigger than it actually is so I modified the following lines of main.c:

Line 25: #define MAX_POSX FIX32(3200)

and

Line 190: // clip camera position
if (npx_cam < FIX32(0)) npx_cam = FIX32(0 ...

I see. Then the code is:

hola.c

#include <genesis.h>
#include "moon.h"

int main()
{

// draw the moon at (12,12)
VDP_drawImage(VDP_PLAN_A, &moon, 12, 12);

while(1)
{
VDP_waitVSync();
}
return 0;
}

moon.res

IMAGE moon "moon.bmp" -1

Thank you! :D

Easier is not it ? :wink:

Nice!

That's a lot easier :D
Now the moon example is working. Thank you!

Would be nice to have an updated version in the wiki.

Here is the code:

hola.c

#include ...

I find that I need to create the .res file in order to generate the moon.h

I can compile the example but I'm getting a weird result.

Here's my code:

#include <genesis.h>
#include "moon.h"

int main()
{

// get the image width (in pixel) ==> should be 8pix aligned
u16 w = moon.w;
// get the ...

Before checking the project settings I can't compile from Eclipse so I tried the command line and I can do it. I'm stuck at the Multi tiles part of the tutorial (the moon) I can't compile the source code from the command line. Here's the error:

Hi!

I was trying to setup and run the HelloWorld demo on Windows 7 but I'm getting this message:
