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

hi,

have you an example ?

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

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

Ok work..

But another question.

I have 100 suns at Screen, but if i move the Cam , nothing move at screen.. ?
normal ?

only camera rotations affect the suns (not camera movement)

Hirogens · 05-28-2009 06:21 PM

Ok,

I can't use Suns for draw my galaxy...

please use particles for space simulation (especially manual drawing)

Hirogens · 05-28-2009 07:03 PM

Particle ?!,

But I must click on each stars...I can click on particle ? and get the coordinnate ?

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)

I have try all the night... don't work
Can you write a little example ?

Hi,

A sample usage is in Bloody Massacre,

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

Sorry, I can't draw a particle..Nothing draw...
