lvcabral/brs-engine v2.6.0

v2.6.0 - Effect Node, roWebSocket and Draw2D Updates

on GitHub

This release adds substantial Roku OS 16.0 feature coverage across the core engine and the SceneGraph extension. The new Effect node brings rounded corners, borders, and linear/radial gradients to Rectangle and Poster (approximated via Canvas2D, since the engine has no real GPU/shader pipeline), paired with a new FloatArrayFieldInterpolator node for animating its array-valued fields and a public ArrayGrid.focusFeedbackPoster field for customizing a grid's focus indicator. The core engine gains a new roWebSocket component with full Node.js and browser support — unlike the raw-socket components, it performs real WebSocket network I/O on both platforms — and ifDraw2D.Clear() now returns a Boolean like DrawLine()/DrawPoint()/DrawRect() already did, with a new roTextureRequest.SetDrawable() controlling whether a texture-manager bitmap can be drawn onto directly. An undefined conditional-compilation name in #if/#elseif now evaluates to false instead of raising a compile error, matching Roku OS 16.0's relaxed rule. The remote-control simulation also gains experimental multi-controller support (multi_controllers=1), an expanded game pad button map, and an analog GetValue() extension on roUniversalControlEvent — simulator-only capabilities with no real-Roku equivalent, whose API may still change in a future release. Also fixed: DrawScaledObject() not mirroring the image for a negative scaleX/scaleY, a SceneGraph focus re-grab being dropped when the competing focus lived in a still-detached subtree, and DynamicKeyGrid not rendering a Key Definition File's own icon/focusIcon bitmaps. Read the full release notes below for more details.

Release Changes

Core Engine

• (brs) Added roWebSocket component (Roku OS 16.0) with full Node.js and browser support by @lvcabral in #1234
• (draw2d) Fixed DrawScaledObject() not mirroring the image for a negative scaleX/scaleY by @lvcabral in #1235
• (draw2d) ifDraw2D.Clear() now returns Boolean and added roTextureRequest.SetDrawable() (Roku OS 16.0) by @lvcabral in #1236
• (brs) An undefined #if/#elseif conditional-compilation name now evaluates to false instead of raising a compile error (Roku OS 16.0) by @lvcabral in #1237
• (brs) Added experimental support for multiple simultaneous game controllers and an analog GetValue() extension on roUniversalControlEvent — simulator only, no real-Roku equivalent, API may change by @lvcabral in #1226

SceneGraph Extension (brs-scenegraph release v0.6.0)

• (rsg) Added new Effect node for rounded corners, borders and gradients (Roku OS 16.0) by @lvcabral in #1230
