orx-timer
Simple timer functionality providing repeat, to run code with a given interval
and timeOut, to run code once after a given delay.
Prerequisites
Add orx-timer to the orxFeatures set in your build.gradle.kts
Usage
orx-timer facilitates two extension functions for Program
fun Program.repeat(intervalInSeconds: Double, count: Int? = null, initialDelayInSeconds: Double = 0.0, action: () -> Unit)
fun Program.timeOut(delayInSeconds: Double, action: () -> Unit)
A simple example looks like this:
fun main() = application {
program {
repeat(2.0) {
println("hello there")
}
extend {
}
}
}
Note that drawing inside the repeat action has no effect. Have a look at the demos listed below for an example of
repeat triggered drawing.
Demos
DemoRepeat01
A simple demonstration on using the repeat method to execute a function
at regular intervals.
Note that drawing inside the repeat action has no effect. See DemoRepeat02.kt to learn how to trigger drawing.
DemoRepeat02
This demonstrates how to combine repeat {} with a postponed event to trigger drawing.
DemoRepeat03
Shows how a repeat block can update a variable used
for rendering. In this demo, the opacity variable is
reduced on every animation frame, and increased to 1.0
every 2 seconds, creating a pulsating animation effect.
DemoTimeOut01
Demonstrates the timeOut function.
It is similar to the repeat function,
but it runs only once after the specified delay in seconds.
