QcClientWeather Class

The weather as the client shows it (decision E-395): the strengths of rain and thunder the server sent, eased so a step of a message never jumps; the climate where the player stands; the flash of the latest lightning; and the thunder still on its way (sound travels 343 m/s, so a strike 170 m away is heard half a second after its flash).

Detailed Description

GUI-free; the session ticks it.

Member Function Documentation

const QcWeather::Climate &QcClientWeather::climate() const

Returns the climate where the player stands.

float QcClientWeather::flash(double ticks) const

Returns the brightness of the lightning flash in 0..1 at ticks (the client tick with its fraction): a bright stroke, a short dark gap, a second stroke, then fading out.

void QcClientWeather::lightning(const QcMsg::Lightning &strike, const QcVec3 &listener, quint64 tick)

The strike seen by a listener at listener in client tick tick: the flash begins, the thunder waits for its time.

QcPrecipitation QcClientWeather::precipitationAt(int y) const

Returns what falls at height y near the player while it rains (QcWeather::precipitationAt).

float QcClientWeather::rain() const

Returns the shown strength of the rain, 0..1.

float QcClientWeather::rainAt(int y) const

Returns the rain strength falling at height y near the player: 0 where it snows or stays dry.

void QcClientWeather::receive(QcMsg::Weather weather)

Takes the strengths and the climate the server sent in weather.

quint64 QcClientWeather::strikes() const

Returns the number of strikes seen since the session began (tests, control interface).

float QcClientWeather::thunder() const

Returns the shown strength of the thunderstorm, 0..1.

QList<QcSoundCue> QcClientWeather::tick(quint64 tick)

One client tick, tick: eases the strengths and returns the thunder due now.

Member Variable Documentation

const float QcClientWeather::easePerTick

The shown strengths move at most this much per tick towards the received ones (twice the server's fade, so they keep up with it).

const int QcClientWeather::flashTicks

A flash lights the sky for this many ticks.

const double QcClientWeather::speedOfSound

Speed of sound in metres per second.

const double QcClientWeather::thunderHearing

Thunder from strikes further away than this is not heard at all.

const double QcClientWeather::thunderPlacement

Thunder further away than this is placed at this distance (towards the strike) and quieter by the ratio, so it stays within the reach of its sound (QcSoundDefinition::maxRange).
