Version 4.0 - beta 7

Major Changes

• Camera System Rewrite

The camera system rewrite changes the way camera matrices are calculated.

The Phaser 3 camera combined position, rotation, and zoom into Camera#matrix. Camera scroll was appended later.

The new camera system uses two matrices. Camera#matrix is now a combination of rotation, zoom, and scroll. A new Camera#matrixExternal property includes camera position. This allows us to cleanly divide the view from the position.

This change doesn't affect how you set camera properties to change the view. It mostly affects internal systems. However, if you use camera matrices directly, be aware that they have changed.

• Camera#matrix now includes scroll, and excludes position.
• Camera#matrixExternal is a new matrix, which includes the position.
• Camera#matrixCombined is the multiplication of matrix and matrixExternal. This is sometimes relevant.
• The GetCalcMatrix(src, camera, parentMatrix, ignoreCameraPosition) method now takes ignoreCameraPosition, causing its return value to use the identity matrix instead of the camera's position.
• GetCalcMatrixResults now includes a matrixExternal property, and factors scroll into the camera and calc matrices.
• To get a copy of a matrix with scroll factor applied, use TransformMatrix#copyWithScrollFactorFrom(matrix, scrollX, scrollY, scrollFactorX, scrollFactorY). This generally replaces cases where phrases such as spriteMatrix.e -= camera.scrollX * src.scrollFactorX were used.

The new system fixes many issues with nested transforms, filters, and other uses of transforms.

Minor Additions

• Add documentation explaining how to modify a SpriteGPULayer efficiently.
• Add SpriteGPULayer#insertMembers method.
• Add SpriteGPULayer#insertMembersData method.
• Add SpriteGPULayer#getDataByteSize method.
• Add non-looping animations to SpriteGPULayer (set animation to loop: false) to support one-time particle effects and dynamic sources.
• Add creation time to SpriteGPULayer members.
• Add documentation for writing a Extern#render function.
• TilemapLayer and TilemapGPULayer now support a parent matrix during rendering.
• Shape now sets filtersFocusContext = true by default, to prevent clipping stroke off at the edges.

Fixes and Tweaks

• Fix missing reference to Renderer events in BatchHandler (thanks @mikuso)
• Fix SpriteGPULayer segment handling (segments changed from 32 to 24 to avoid problems with 32-bit number processing)
• Allow negative acceleration in SpriteGPULayer member animations using Gravity.
• Rearrange SpriteGPULayer data encoding.
• Fix SpriteGPULayer failing to generate frame animations from config objects.
• Allow TextureSource#setFlipY to affect all textures (except compressed textures, which have fixed orientation).
• WebGLProgramWrapper now correctly recognizes uniforms with a value of undefined and can recognize if they have not changed and do not need updates.
• Set roundPixels game option to false by default. It's very easy to get messy results with this option, but it remains available for use cases where it is necessary.
• Throw an error if DOMElement has no container.
• Fix TileSprite applying smoothPixelArt game option incorrectly.
