Method Detail

getNow

long getNow()

Current time for this tick in nanoseconds. Also time elapsed from the start of game. This time does not change while the game is paused. This time does not change while within the same tick.

Returns:

current time in nanoseconds

getPlaytime

default long getPlaytime()

Gets the value of the property playtime.

getTick

default long getTick()

Returns current tick (frame). When the game has just started, the first cycle in the loop will have tick == 1, second cycle - 2 and so on.

The update to this number happens when a new update cycle starts.

Returns:

current tick

tpf

double tpf()

Returns:

time per frame

runAtInterval

TimerAction runAtInterval(Runnable action,
                          javafx.util.Duration interval)

The Runnable action will be scheduled to run at given interval. The action will run for the first time after given interval.

Note: the scheduled action will not run while the game is paused.

Parameters:

action - the action

interval - time

runAtIntervalWhile

TimerAction runAtIntervalWhile(Runnable action,
                               javafx.util.Duration interval,
                               javafx.beans.property.ReadOnlyBooleanProperty whileCondition)

The Runnable action will be scheduled for execution iff whileCondition is initially true. If that's the case then the Runnable action will be scheduled to run at given interval. The action will run for the first time after given interval

The action will be removed from schedule when whileCondition becomes false.

Note: the scheduled action will not run while the game is paused

Parameters:

action - action to execute

interval - interval between executions

whileCondition - condition

runOnceAfter

TimerAction runOnceAfter(Runnable action,
                         javafx.util.Duration delay)

The Runnable action will be executed once after given delay

Note: the scheduled action will not run while the game is paused

Parameters:

action - action to execute

delay - delay after which to execute

reset

void reset()

Clears all registered timer based actions.
