NDS special effect library

Contents

What is this?

This is a simple library for controlling special effects functions in the form of macros for the Nintendo DS's sprite and background hardware. These functions are available for both screens.

Where do i get it?

Currently the sources for this are part of LibThds. The source can be downloaded via SVN (see libthds page) or directly from the svn httpd:

Okay I'm convinced. Let's put it to atcion.

Examples

Fadeout
Fade screen 0 to black.

thSfxEnable(0, SFX_BRIGHTDEC, SFX_BG0|SFX_BG1|SFX_BG2|SFX_BG3|SFX_OBJ|SFX_BD, SFX_NONE);
int fade=0;
do {
  thSfxSetBrightness(0, fade);
  swiWaitForVBlank();
} while(++fade<=SFX_MAX);

Fade to White
Fade screen 1 to White slowly.

thSfxEnable(1, SFX_BRIGHTINC, SFX_BG0|SFX_BG1|SFX_BG2|SFX_BG3|SFX_OBJ|SFX_BD, SFX_NONE);
int fade=0;
do {
  thSfxSetBrightness(1, fade>>2);
  swiWaitForVBlank();
} while(++fade<=(SFX_MAX<<2));

Blend backgrounds with sprites
Blend sprites evenly with backgrounds

thSfxEnable(0, SFX_BRIGHTINC, SFX_OBJ, SFX_BG0|SFX_BG1|SFX_BG2|SFX_BG3|SFX_BD);
thSfxSetAlphaBlend(0, 15, 15);
