Here is a simple example demonstrating how to use Dark Physics with Dark GDK. The program is very simple - it drops a lot of spheres into a very basic scene.
void DarkGDK ( void )
{
dbPhyStart ( );
dbAutoCamOff ( );
dbSyncOn ( );
dbSyncRate ( 60 );
dbColorBackdrop ( 0 );
dbSetTextFont ( "tahoma" );
dbSetTextSize ( 32 );
dbSetDir ( "media" );
dbMakeLight ( 1 );
dbSetDirectionalLight ( 1, -5, -5, 5 );
dbLoadImage ( "stripe5.png", 1 );
dbMakeObjectSphere ( 2, 400, 48, 48 );
dbTextureObject ( 2, 1 );
dbScaleObjectTexture ( 2, 6, 6 );
dbSetObjectCull ( 2, 0 );
dbSetAmbientLight ( 80 );
dbGhostObjectOn ( 2, 0 );
dbRotateObject ( 2, 0, 0, 90 );
dbMoveCamera ( -60 );
dbLoadImage ( "stripe6.png", 3 );
dbMakeObjectBox ( 10, 50, 1, 50 );
dbPositionObject ( 10, 35, -10, 0 );
dbRotateObject ( 10, 0, 0, 60 );
dbGhostObjectOn ( 10, 0 );
dbTextureObject ( 10, 3 );
dbPhyMakeRigidBodyStaticBox ( 10 );
dbMakeObjectBox ( 11, 50, 1, 50 );
dbPositionObject ( 11, 0, -40, 0 );
dbRotateObject ( 11, 0, 0, -20 );
dbTextureObject ( 11, 3 );
dbPhyMakeRigidBodyStaticBox ( 11 );
dbPositionCamera ( -46.8f, 26.8f, -49.0f );
dbRotateCamera ( 34.7f, 46.4f, 0.0f );
dbSetAmbientLight ( 30 );
int y = 20;
int x = 40;
int z = 0;
for ( int a = 100; a < 500; a++ )
{
dbMakeObjectSphere ( a, 5, 20, 20 );
dbPositionObject ( a, ( float ) x, ( float ) y, ( float ) z );
dbPhyMakeRigidBodyDynamicSphere ( a );
dbColorObject ( a, dbRgb ( dbRnd ( 255 ), dbRnd ( 255 ), dbRnd ( 255 ) ) );
dbSetObjectSpecular ( a, dbRgb ( dbRnd ( 255 ), dbRnd ( 255 ), dbRnd ( 255 ) ) );
dbSetObjectSpecularPower ( a, 255 );
dbSetObjectAmbient ( a, 0 );
y = y + 20;
z = -10 + dbRnd ( 20 );
}
dbSetDir ( ".." );
float r = 80;
float h = -10;
float angle = 180;
int count = 0;
float xpos = 0;
float zpos = 0;
while ( !dbEscapeKey ( ) )
{
count++;
xpos = 10.0f * dbSin ( ( float ) count );
angle = angle - 0.4f;
if ( r < 1.0f )
r = 1.0f;
xpos = r * dbSin ( angle );
zpos = r * dbCos ( angle );
dbPositionCamera ( 0, xpos, h, zpos );
dbPointCamera ( 0, 0.0f, h, 0.0f );
dbCenterText ( dbScreenWidth ( ) / 2, 20, "Bouncing Objects" );
dbRotateObject ( 2, 0.0f, dbObjectAngleY ( 2 ) + 0.3f, 0.0f );
dbPhyUpdate ( );
dbSync ( );
}
}
It integrates into Dark GDK quite well.
