Code draw nothing !!!!
Hi all,

This code draw nothing...but the demo of suns.cpp work perfectly

Have you a solution ?

regards
Christophe [Hirogens]

Code:
#pragma pack()
struct PosG
{
    double X;
    double Y;
    double Z;
};

PosG PositionGalaxie[100];
int NbStars = 0;


int Cpt = 0;
Sun sunTab[100];

chargeFichierGalaxy();
for (Cpt = 0;Cpt < 100;Cpt++)
{
    sunTab[Cpt]       = Suns.New();
    sunTab[Cpt].set(*Images("gfx/sky/sun.gfx"));
    sunTab[Cpt].pos   = !Vec((Flt)PositionGalaxie[Cpt].X, (Flt)PositionGalaxie[Cpt].Y, (Flt)PositionGalaxie[Cpt].Z);

}

You shouldn't use additional Sun objects 'Sun sunTab[100];'
but please use 'Suns' container instead

use reference
Sun &sun=Suns.New();

or suns array after it has been created
Suns[i]

Re: Code draw nothing !!!!
please use these functions:

Code:
Bool DrawParticleBegin(Image &image,Byte glow                                         ); // call this at start of drawing particles, 'glow'=glow amount 0..255, false on fail
void DrawParticleAdd  (Color  color,Flt opacity,Flt radius,Flt angle,Vec &pos,Vec &vel); // call this repeatedly for each particle
void DrawParticleEnd  (                                                               ); // call this after drawing  all  particles

I have search in entire directory, and I no found example to use it.

Hi,

this is a sample

Code:
inline void DrawParticle(Image &image,Byte glow,Color color,Flt opacity,Flt radius,Flt angle,Vec &pos,Vec &vel) // draw a single particle
{
   if(DrawParticleBegin(image,glow))
   {
      DrawParticleAdd(color,opacity,radius,angle,pos,vel);
      DrawParticleEnd();
   }
}

it's in the particles header file, just below the mentioned functions
this function is also used in Bloody Massacre (DrawParticle)

Hi,

A sample usage is in Bloody Massacre,

This is just a Particle drawing function, which can be called instead of Particles::draw
