Game::World.update and ocean
Soo, I was playing around with Game::World.update(0,0,0); and I noticed it changes the level of the ocean, if you have previously set ocean with:
Water.plane.set(Vec(0,-300,0),Vec(0,1,0));

Then calling Game::World.update() would reset the position to Water.plane.set(Vec(0,0,0),Vec(0,1,0));?

Maybe if someone can explain why?

RE: Game::World.update and ocean
In the water.h file:

struct WaterClass : WaterMtrl // Main water control
has this for:
Plane plane ; // water plane , , default=(pos(0,0,0), normal(0,1,0))


in v1 tut 22 water.cpp


Code:
/******************************************************************************/
#include "stdafx.h"
/******************************************************************************/
Mesh terrain;
/******************************************************************************/
void InitPre()
{
   App.name("Water");
   App.flag=APP_FULL_TOGGLE|APP_MS_EXCLUSIVE;
   DataPath("../data");
   Paks.add("engine.pak");

   D.full(true).ambientPower(0.4).hpRt(true);

   Cam.at.set(0,2,0);
   Cam.pitch=-0.5f;
   Cam.dist =30;
   Cam.yaw  =2.8f;
}
Bool Init()
{
   terrain.load("obj/terrain/0.mesh");                                      // terrain
   terrain.scale(Vec(1,10,1)).move(Vec(0,5,0));                             // scale and move terrain vertically
   Sky.atmospheric();                                                       // sky
   Sun.image="Env/Sky/sun.gfx"; Sun.light_color=1-D.ambientColor(); // sun

   Water.colorMap(Images("Env/Water/0.gfx")).normalMap(("Env/Water/0.n.gfx")).reflectionMap(("Env/Water/reflection.gfx")); // set water from textures
   Water.draw      =true; // enable drawing
   Water.wave_scale=0.8f; // adjust wave scales

   return true;
}
void Shut()
{
}
/******************************************************************************/
Bool Update()
{
   if(Kb.bp(KB_ESC))return false;
   CamHandle(0.01f, 500, CAMH_ZOOM|(Ms.b(1)?CAMH_MOVE:CAMH_ROT));

   // here you can optionally set different water surface plane
   if(Kb.b(KB_UP  ))Water.plane+=Vec(0,1,0)*Time.d(); // move water surface plane upwards
   if(Kb.b(KB_DOWN))Water.plane-=Vec(0,1,0)*Time.d(); // move water surface plane downwards

   // update water waves movement
   Water.update(Vec2(0.01f, 0.01f));

   return true;
}
/******************************************************************************/
void Render()
{
   switch(Renderer())
   {
      case RM_PREPARE: terrain.draw(MatrixIdentity); break;
   }
}
void Draw()
{
   Renderer(Render);
   D.text(0, 0.9f, S+"Fps "+Time.fps());
   D.text(0, 0.8f, "Press up/down keys to change water level");
}
/******************************************************************************/

RE: Game::World.update and ocean
I am sorry, but what does this have to do with Water.plane.set(Vec(0,-300,0),Vec(0,1,0)); getting its values reset when you call Game::World.update()?

I have absolutely no idea what the reply you just made was about?

On Update() the default value gets restored if you do not manually overwrite the default value of the header, if I am not mistaken.

It's examples of others using water.
