Detailed Description

Water manager/renderer.

Water is drawn where the terrain is below specified level. The mapping is based on terrain coordinates - for each "brick" coordinate, the level of terrain is tested. For every Y coordinate, many lines in X direction are created (WaterLines).

There are two parts of drawing process: drawing the background image blocking the normal sky layer and drawing the surface of water. The surface is drawn with texture, so with proper texture it can be lava.

Member Function Documentation

Flush()

void Gfx::CWater::Flush

(

)

Removes all the water.

Create()

void Gfx::CWater::Create	(	WaterType	type1,
		WaterType	type2,
		const std::string &	fileName,
		Color	diffuse,
		Color	ambient,
		float	level,
		float	glint,
		Math::Vector	eddy
	)

Creates all expanses of water.

DrawBack()

void Gfx::CWater::DrawBack

(

)

Draw the back surface of the water.

This surface prevents to see the sky (background) underwater!

DrawSurf()

void Gfx::CWater::DrawSurf

(

)

Draws the flat surface of the water.

SetLevel()

void Gfx::CWater::SetLevel

(

float

level

)

Changes the level of the water.

GetLevel() [1/2]

float Gfx::CWater::GetLevel

(

)

Returns the current level of water.

GetLevel() [2/2]

float Gfx::CWater::GetLevel

(

CObject *

object

)

Returns the current level of water for a given object.

SetLava()

void Gfx::CWater::SetLava

(

bool

lava

)

Management of the mode of lava/water.

AdjustEye()

void Gfx::CWater::AdjustEye

(

Math::Vector &

eye

)

Adjusts the eye of the camera, not to be in the water.

EventFrame()

bool Gfx::CWater::EventFrame ( const Event &  event )

protected

Makes water evolve.

LavaFrame()

void Gfx::CWater::LavaFrame ( float  rTime )

protected

Makes evolve the steam jets on the lava.

AdjustLevel()

void Gfx::CWater::AdjustLevel ( Math::Vector &  pos, Math::Vector &  norm, Math::Point &  uv1, Math::Point &  uv2  )

protected

Adjusts the position to normal, to imitate reflections on an expanse of water at rest.

GetWater()

bool Gfx::CWater::GetWater ( int  x, int  y  )

protected

Indicates if there is water in a given position.

CreateLine()

void Gfx::CWater::CreateLine ( int  x, int  y, int  len  )

protected

Updates the positions, relative to the ground.

VaporFlush()

void Gfx::CWater::VaporFlush ( )

protected

Removes all the steam jets.

VaporCreate()

bool Gfx::CWater::VaporCreate ( ParticleType  type, Math::Vector  pos, float  delay  )

protected

Creates a new steam.

VaporFrame()

void Gfx::CWater::VaporFrame ( int  i, float  rTime  )

protected

Makes evolve a steam jet.
