Constructor & Destructor Documentation

TileStorm::TileStorm ( void )

Initialize the effect with default values. The default number of tile-particles is one (1), and so using this constructor is generally not very useful.

TileStorm::TileStorm	(	Vector	vPos,
		Vector	vFce,
		float	fSAngle,
		float	fFric,
		float	fRand,
		int	iParticles,
		int	tex
	)

Initialize the effect with specific initial values. Note that the class member (int) iNumParticles will be clamped to a maximum value of MAX_PARTICLES.

Here is the call graph for this function:

TileStorm::~TileStorm ( void )

This function is the default destructor, which frees the memory allocated to holding the particle structure data.

Here is the caller graph for this function:

bool TileStorm::Step ( float timeStep )

Step the effect forward in time by a specified amount. This will update the effect's particles' position, orientation, etc. and prepare the effect for being drawn to the screen. This function may change the boolean member bParticlesExpired to indicate when the energy of all particles in the system has reached zero.
