Changelog

0.10.2 (SNAPSHOT)

0.10.1

Changes

Fix miscalculation for scene-graph Cotnrol.anchor() for TOP_* related layouts.
Fix AssetProvider to asset preparation logic not preparing additional assets after the initial preparation.

0.10.0

Breaking

Replace all of OpenGL with WebGPU. The overall API is mostly the same, save for the specifics of having to use WebGPU. These changes are too large to fit in a changelog but can be checked out on the documentation and migrated.
- Much of the API under graphics.* has changed but stayed relatively the same. E.g. SpriteBatch contains the same begin() -> draw() -> end() flow but requires WebGPU specific classes.
- graphics.gl.* classes replaced with graphics.webgpu.*
Remove the Android target until a generator can be created for the WGPU natives for JNI (Future update).
The module group id, for defining in dependencies, has been changed from com.lehaine.littlekt to com.littlekt.
The scene-graph module has been extracted into its own package and will explicitly be defined in your dependencies: com.littlekt:scene-graph
Remove FrameBufferNode and related UI classes. Use CanvasLayerContainer and CanvasLayer for FBO related purposes.
Remove FrameBuffer class. WebGPUs RenderPass is essentially a Framebuffer / Render target.
Remove GlslGenerator and all related classes. Use WGSL for your shader needs, either by loading them from a file or directly in a string.
Remove vSync and backgroundColor configuration options.
Remove Game<T> and Scene<T> classes as they aren't in scope of the framework.
Rename Disposable to be Releasable as well as dispose() to release().
Remove FitViewport and FillViewport as they don't work with the current viewport limitations WebGPU imposes. WebGPU doesn't allow out-of-bounds viewports which causes a fatal error. There is no workaround without getting clever with shaders.
Update TextureSlice.originalWidth/Height & TextureSlice.packedWidth/Height to actualWidth/Height and trimmedWidth/Height, respecitively.

Update Dokka gradle plugin to 1.9.20.

Fixes

Fix InputQueueProcessor to clear events pool even when no InputProcessor exists.
Fix SpriteBatch default size to be back to 1000 sprites instead of 8191 sprites.
- This makes it consistent with TextureArraySpriteBatch as well as increases performance if using the default size and using less than 8191 sprites.

v0.7.0

Changes

Update Kotlin to 1.8.20.
Update FrameBuffer class is now open.
Add new forEachTileInView to LdtkLayer to iterate over tiles current in the view bounds without rendering.
Breaking: Move BlendMode and DepthStencilMode out of the graph package and into the graphics.utils.
Add new setBlendFunction(blendMode) to Batch.
Breaking: update createShader to return the type of vertex and fragment shaders instead of the super class.
Add FrameBuffer.use extension similar to Batch.use.
Breaking: Shader.parameters are now to be used with a LinkedHashSet instead of a MutableList(). mutableListOf(param1, param2) -> linkedSetOf(param1, param2).
Breaking: Update Shader.parameters to grab parameters by variable name instead of index. parameters[0] -> parameters["u_texture"]
Breaking: GlslGenerator.texture2D, GlslGenerator.shadow2D, and GlslGenerator.texture now returns a constructor delegate instead of a literal. val color = texture2D(...) -> val color by texture2D(...)

Fixes

v0.6.3

Fix an issue with Button not calculating label sizing when added after scene creation.

v0.6.2

This contains only a single change related to the GLSLGenerator.

Update GLSLGenerator uniform delegates to only add to the Shader.paremeters only when has its value used in the source. Due to some static conditions some uniforms may not be used while still being defined in the paramters list. When creating a ShaderProgram with WebGL, it would throw shader compilation error due to not finding in the glsl source. This was preventing a SceneGraph from being rendered on the Web due to the default 3D model shader.

v0.6.1

This contains fixes for Mac support.

Fixes

Add new HdpiMode for JVM platforms. Setting to HdpiMode.PIXELS will allow correct display on Macs with retina displays.
Update GlVersion to handle comparisons of versions correctly. This fixes issues in the GlslGenerator.
Update LjwglGL to only use the extension framebuffer and renderbuffer calls if the OpenGL version is < 3.
Fix shader compilation errors on Macs.

v0.6.0

This version is full of breaking changes, mainly to mesh creation and handling, to make way for adding some basic 3d related graphics and handling.

Highlights

Basic 3D support This is experimental and not really meant to be used in a real game yet:
- Adds a few new nodes to the SceneGraph to handle rendering 3D meshes and models:
  - Node3D, VisualInstance, Model, and Camera3D.
- Extremely basic lighting (this will improve in the future).
- Skeletal animation.
- glTF loading and basic material rendering: resourceVfs["myModel.glb"].readGltfModel().
- New PerspectiveCamera class.
New MeshGeometry class. Replaces the old MeshBatcher but doesn't require to make a new Mesh instance to create the vertices. An instance can be passed into a Mesh for it to use.
New MeshBuilder class that uses the new MeshGeometry class to help facilitate generating meshes and vertices.
Various GLSL generator improvements and optimizations
- Declare and set value of variable in line.
- 3.3 layout locations support.
- Add new predicate option when declaring an attribute or varying for conditional shaders.
Vec4 updates to handle Quaternion related math

Breaking

Update BaseButton.buttonGroup to be private and added a new setButtonGroup(group) function to handle setting button groups.

Migration:

Previous:

val myButtonGroup = ButtonGroup()
button {
  buttonGroup = myButtonGroup
  buttonGroup.buttons += this
}

New:

val myButtonGroup = ButtonGroup()
button {
  setButtonGroup(myButtonGroup)
}

Move all 2D graphic related items to new subpackage call g2d. To migrate: append .g2d to all imports using any 2D related class.
Mesh changes:
- Removed MeshBatcher and replaced with separate MeshGeometry.
- If you are using a Mesh instance that was using the batcher and making use of Mesh.addVertex do the following:
  - Previously: mesh.addVertex { ... }. New: mesh.geometry.addVertex { ... }
- Removed useBatcher in favor of using MeshGeometry to create a Mesh without binding it.
SceneGraph.showDebugInfo is no longer able to be changed. To request debug rendering use the new SceneGraph.requestShowDebugInfo. The reason for this change was the showDebugInfo was taking effect immediately and throwing exceptions due to the internal Batch not being ready to render with ShapeRenderer and such. The request will take into effect after the current frame finishes rendering. SceneGraph.showDebugInfo will contain the true value of debug rendering.

Changes

Fix BaseButton pressed & disabled properties incorrectly comparing new value with a wrong value affecting toggle buttons.
Update NodeList to handle Node.updateInterval values less than 1. Anything less than 1 will now not update itself or its children.
Add useOriginalSize option to TextureRect node to allow positioning the TextureSlice based off the original size before packing and trimming.
Fix SceneGraph touch focuses not being cleared after a TOUCH_UP event being fired resulting in thousands of elements in the list.
Fix SceneGraph to fire the correct MOUSE_EXIT input event with pointers last over an input control.
Update Control.hasPoint to handle rotated control nodes
Fix CanvasItem.toLocal and CanvasItem.toGlobal to use its respective matrices for calculation of the coordinates.
Fix Control.hit not handling rotated nodes in its calculation
Update all checks of rotation == Angle.ZERO to use a normalized angle and fuzzy zero checking. This results in angles of 360 degrees to satisfy the condition.
Fix TOUCH_UP event not being sent to input & unhandledInput functions when not clicking on a Control node.
Fix multiple calls to debugRender in the SceneGraph when using any nested CanvasLayer.
Fix FrameBufferNode not propagating debug render calls to its children.
Add new InputEvent.canvasX and InputEvent.canvasY to get coordinates of the event in the CanvasItem.canvas coordinates. This is useful when nesting Canvas nodes.
Update existing Control nodes that use uiInput to check against new InputEvent.canvasX and InputEvent.canvasY coordinates.
Fix GlyphLayout not calculating glyph advances properly resulting in incorrect wrapping calculations
Fix when a Control node should calculate its minimum size. This fixes issues with labels not using the correct layout height.
Add getOrNull(Int) to all variants of ArrayList data structure.

Libraries

Update kotlin to 1.8.10.
Update kotlinx.serialization to 1.5.0-RC.
Update kotlinx.atomicfu to 0.19.0.

v0.5.3

Changes

Fix NodeList not handling removing children correctly, missing onDestroy calls and not removing every child.

v0.5.2

Changes

Fix NodeList not adding newly added nodes to the internal sortedNodeList preventing nodes from being rendered.

v0.5.1

Breaking

Update EmptyDrawable to be an immutable singleton object instead of a class. Any attempted changes to this will throw an exception.
- Migration: val drawable = EmptyDrawable() to val drawable = createEmptyDrawable() or val drawable = EmptyDrawable

Changes

Update ScrollContainer vertical scrollbar to extend the entire height of the container.
Update ScrollContainer add new Drawable properties that can be overridden.
Update Scrollbar add new Drawable properties that can be overridden.
Fix Scrollbar grabber height and position not fully reaching the correct position at the end of the scrollbar.
Adds new child tree positioning methods. NodeList updated to use just an array list to handle the indexing as the multiple collections were not able to handle the movement changes.
- sendChildToTop() - sends child to top of parent tree
- sendChildAtToTop() - sends child at index to top of parent tree
- sendChildToBottom() - sends child to bottom of parent tree
- sendChildAtToBottom() - sends child at index to bottom of parent tree
- addChildAt() - adds new child to parent node at specified index
- swapChildren() - swap child positions in the parent tree
- swapChildrenAt() - swap children node positions at indices in the paren tree

v.0.5.0

Highlights

Add ScrollContainer, VScrollBar, and HScrollBar control nodes for scroll handling
Add automatic caching of Control theme values when first grabbing the theme value.
- For Example: getThemeDrawable() will return a result and then is cached in the drawableCache map. Any subsequent calls to getThemeDrawable() will first check in the drawableOverrides and then in the drawableCache map and return a result if it exists.
- When a theme owners theme changes, the theme owners and its child control nodes will all have their caches cleared.
Add an experimental API for rendering scalable TrueType Fonts (TTF) called VectorFont. A sample VectorFontTest exists for usage.
Add a GestureProcessor interface with a GestureController input processor to handle gesture detection and callbacks. Comes with a GestureProcessorBuilder class for easy callback creation. A helper extension Input.gestureController to easily create and add the gesture controller as an input processor to the input.
Update default theme colors and tweak default UI assets to be slightly more presentable.
Add column and row DSL aliases for VBoxContainer and HBoxContainer containers.

Breaking

Context.onRender, Context.onPostRender, Context.onPostRunnable, and Context.onResize are now non-suspending. This fixed issues with the Android and Web platforms from creating unneeded coroutines every frame. Wrap any suspending calls called within these callbacks in a coroutine, KtScope.launch { }, or check if the suspending function can be made non-suspending.

New

add: EmptyDrawable to handle drawables that don't need drawn.
add: Additional vec3 CanvasLayer.canvasToScreen methods.

val viewport = ExtendViewport(480, 270)
val camera = OrthographicCamrea().apply {
    this.viewport = viewport
}

New:

val viewport = ExtendViewport(480, 270)
val camera = viewport.camera

remove SceneGraph.viewport: Viewport and SceneGraph.camera and replaced with the ViewportCanvasLayer node.

add: CanvasLayer node that creates a separate OrthographicCamera for rendering instead of inheriting the base camera from the SceneGraph. For example: When rendering certain nodes at a low resolution using a Viewport to render UI at a higher resolution. This contains an instance to a Viewport but isn't used directly to render children. A new node called ViewportCanvasLayer can be used to render children nodes with a separate viewport.
add: ViewportCanvasLayer to use separate Viewport to render children nodes in a SceneGraph.
add: FrameBufferNode which is a CanvasLayer to allow rendering children nodes directly to a FrameBuffer. The FrameBuffer texture is then available to be rendered in a separate node.

add: tmod and targetFPS properties to SceneGraph to be used as another way to handle frame independent movements.
add: three new lifecycle calls to a Node: onPreUpdate, onPostUpdate, and onFixedUpdate as well as their respective Signal types. The onFixedUpdate comes with a few more properties to handle changing the fixed time step and as well as an interpolating ratio.
- SceneGraph.fixedTimesPerSecond: can be used to set the amount of times onFixedUpdate is call per second
- SceneGraph.fixedProgressionRatio: is an interpolation ratio that can be used to render nodes that use onFixedUpdate for movement / physics.
add: input and unhandledInput callbacks to all Node.
- input: is called whenever there is an InputEvent generated and is propagated up the node tree until a node consumes it.
- unhandledInput: is called when an InputEvent isn't consumed by input or the UI.
add: resizable, maximize, and windowPosition configuration parameters to JVM.
add: ppu and ppuInv properties to SceneGraph and Node that allow setting the Pixels per Unit which is used for rendering.

add: AnimationState optional state machine stack that can be to register animation states that will be played based on a predicate.
add: CropType options to TexturePacker: NONE, FLUSH_POSITION, and KEEP_POSITION.
add: ShapeRenderer class to handle drawing shapes, lines, and paths using a Batch instance and a TextureSlice.
