Package-level declarations

Types

class AnimatedSprite(var slice: TextureSlice = Textures.white, var anchorX: Float = 0.0f, var anchorY: Float = 0.0f) : AnimationPlayer<TextureSlice>

Animation

class Animation<KeyFrameType>(val frames: List<KeyFrameType>, val frameIndices: List<Int>, val frameTimes: List<Duration>)

Animation based class that holds info on what frames to be animating. Recommended to be used with AnimationPlayer to assist in playing back the frames.

AnimationBuilder

class AnimationBuilder<T>(frames: List<T>)

An Animation builder to help create custom animations easily.

AnimationPlayer

open class AnimationPlayer<KeyFrameType>

Enables playback of Animation classes.

AnimationType

enum AnimationType : Enum<AnimationType>

The playback types of animation.

Batch

interface Batch : Disposable

NinePatch

class NinePatch(slice: TextureSlice, val left: Int, val right: Int, val top: Int, val bottom: Int)

Creates a ninepatch by slicing up the TextureSlice into nine patches which produces clean panels of any size, based on a small texture by splitting it into a 3x3 grid. The drawn, the texture tiles the textures sides horizontally or vertically and the center on both axes but doesn't scale or tile the corners.

Particle

class Particle(var slice: TextureSlice)

ParticleSimulator

class ParticleSimulator(maxParticles: Int)

SpriteBatch

class SpriteBatch(val context: Context, val size: Int = 8191) : Batch

Draws batched quads using indices.

TextureArraySpriteBatch

class TextureArraySpriteBatch(val context: Context, val size: Int = 1000, maxTextureSlots: Int, maxTextureWidth: Int, maxTextureHeight: Int, textureArrayMagFilter: TexMagFilter = TexMagFilter.NEAREST, textureArrayMinFilter: TexMinFilter = TexMinFilter.NEAREST) : Batch

Requires GLES 3.0!

TextureAtlas

class TextureAtlas : Disposable

Holds all the TextureSlice entries of the atlas that was read and loaded in.

TextureSlice

open class TextureSlice(var texture: Texture, x: Int = 0, y: Int = 0, width: Int = texture.width, height: Int = texture.height)

Functions

createAnimation

fun TextureAtlas.createAnimation(prefix: String, action: AnimationBuilder<TextureSlice>.() -> Unit): Animation<TextureSlice>

Create an animation from a prefix of the names of the sprites in a TextureAtlas using an AnimationBuilder to specify the frame index orders and times.

draw

fun Particle.draw(batch: Batch)

fun ParticleSimulator.draw(batch: Batch)

getAnimation

fun TextureAtlas.getAnimation(prefix: String = "", defaultTimePerFrame: Duration = 100.milliseconds): Animation<TextureSlice>

Creates an animation from a prefix based on the names of the sprites in a TextureAtlas.

use

inline fun <T : Batch> T.use(projectionMatrix: Mat4? = null, action: (T) -> Unit)
