Day-Night Cycle

[Shard]

Hey everyone. So I've written a(n okay) day-night cycle but I'm having a little trouble placing the corona for the sun to make it look realistic and I was wondering if someone code help my code out a little bit.

 

The problem I'm having right now is making the corona show up and making it rotate along with the light.

 

void World::CreateCycle(int time = 0)
{

time = (15*time) - 90;

this->cycle = true;



//Sunlight
this->sunLight = CreateDirectionalLight();
PositionEntity(this->sunLight, Vec3(0,0,0));
RotateEntity(this->sunLight,Vec3(time,0,0));

sun = CreateCorona();
PaintEntity(sun, LoadMaterial("abstract::flare1.mat"));
SetCoronaRadius(sun,10,30);
PositionEntity(sun,Vec3(0,500,0));

////Moonlight
//this->moonLight = CreateDirectionalLight();
//PositionEntity(this->moonLight, Vec3(0,0,0));
//RotateEntity(this->moonLight,Vec3(time + 180,0,0));
//EntityColor(this->moonLight,Vec4(0));

}

void World::UpdateCycle()
{

TurnEntity(this->sunLight,Vec3(.5,0,0),1);

TVec3 sunPos = EntityPosition(sun);

sunPos.X = 500*cos(.5);
sunPos.Y = 500*sin(.5);

PositionEntity(sun,sunPos);

}

Try making your directional light the parent to your corona. It should just follow it then.

Well if you notice the directional light has been placed at 0,0,0 and is rotated at that spot. But the corona has to be up in the sky.

 

I did try it in code but it didn't result with any changes.
