# PIXI-Kotlin
This is a simple example of what a [PIXI.js](https://github.com/pixijs/pixijs) transcription in Kotlin could look like.
For now, there are all the classes, interfaces, enums, functions, type aliases, and objects. The private members are not present.
The types are from [`PIXI 6.5.2`](https://github.com/pixijs/pixijs/releases/tag/v6.5.2).
## Usage
To use it in a project, just add this to your dependencies:
```kotlin
repositories {
...
mavenLocal()
}
dependencies {
implementation("io.github.ayfri:PIXI-Kotlin:VERSION")
}
```
If you want to add optional PIXI modules, you have to implement them in your project.
```kotlin
const val PIXI_KOTLIN_VERSION = "VERSION"
dependencies {
implementation("io.github.ayfri:PIXI-Kotlin:PIXI_KOTLIN_VERSION")
implementation("io.github.ayfri:PIXI-Kotlin-unsafe-eval:PIXI_KOTLIN_VERSION")
}
```
## Example
Simple application with a sprite, size change when clicking.
```kotlin
fun main() {
val app = application {
backgroundColor = Color(120, 200, 230)
resizeTo = window
}
app.addToBody()
val bunny = sprite("bunny.png") {
setPositionFromWindow(0.5, 0.5)
anchor.set(0.5)
interactive = true
addToApplication(app)
}
bunny.on(DisplayObjectEvents.mousedown) {
bunny.scale.set(1.1)
}
bunny.on(DisplayObjectEvents.mouseup) {
bunny.scale.set(1.0)
}
}
```
Application with keymap and test if sprite sticks out of area.
```kotlin
fun main() {
val app = application {
resizeTo = window
}
app.addToBody()
val speed = 10.0
val sprite = sprite(generateBlankTexture(app) {
width = 300.0
height = 300.0
color = Color(255, 0, 0)
}) {
addToApplication(app)
anchor.set(0.5)
setPositionFromApplication(app, 0.5, 0.5)
window["sprite"] = this
}
val area = Rectangle(0.0, 0.0, app.screen.width, app.screen.height)
app.renderer.on(AbstractRendererEvents.resize) {
area.setSize(app.screen.width, app.screen.height)
}
val english = "en" in window.navigator.languages.elementAtOrElse(0) { window.navigator.language }
KeyMap(
mapOf(
"forward" to setOf(if (english) "W" else "Z", "ArrowUp"),
"backward" to setOf("S", "ArrowDown"),
"left" to setOf(if (english) "A" else "Q", "ArrowLeft"),
"right" to setOf("D", "ArrowRight"),
"power" to setOf(" ")
),
ignoreCase = true
).apply {
onKeep("forward") {
if ((sprite.hitBox.top + speed * 2) > area.top) sprite.y -= speed
}
onKeep("backward") {
if ((sprite.hitBox.bottom - speed * 2) < area.bottom) sprite.y += speed
}
onKeep("left") {
if ((sprite.hitBox.left + speed * 2) > area.left) sprite.x -= speed
}
onKeep("right") {
if ((sprite.hitBox.right - speed * 2) < area.right) sprite.x += speed
}
onPress("power") {
sprite.alpha = if (sprite.alpha == 0.1) 1.0 else 0.1
}
}
}
```
