v1.9.0

Issues for 1.9.0

• New features
  • No Cgo on Windows!
    • You can build and run Ebiten games without C compilers on Windows! (Issue 171)
  • Metal on macOS
    • Now Ebiten uses Metal instead of OpenGL on macOS. (Issue 621)
  • Performance improvement
    • e.g. Speed improvement by simplifying shaders (Issue 762, Issue 812)
    • e.g. Memory usage at Ogg decoding was significantly reduced (Issue 733)
• New APIs
  • Graphics
    • func (i *Image) SubImage(r image.Rectangle) image.Image: specifies a part of an image. This replaces DrawImageOptions's SourceRect.
    • func (img *Image) Set(x, y int, clr color.Color): sets a pixel at the specified position on an image. Now *ebiten.Image implements the standard's draw.Image interface.
    • Address: represents whether the texture is repeated at DrawTriangles.
• Deprecated APIs
  • Graphics
    • DrawImageOptions's SourceRect: Use (*Image).SubImage instead.
• Bug fix
  • Monitor issues
    • e.g. The window was sometimes not opened in the current monitor (Issue 829)
  • Several mobile issues
    • e.g. Strange lines on an Xperia phone (Issue 622)
    • e.g. Crash when creating a very small image on old iOS devices (Issue 810)
  • Go 1.12 issues
    • e.g. OpenAL crashes (Oto Issue 65)

  • audio.Player objects could be leaked when they play
  • ebiten.SetWindowDecorated didn't work
  • ebiten.SetWindowIcon before Run didn't work
  • ebiten.SetCursorVisible before Run didn't work

v1.8.0

Issues for 1.8.0

• New features
  • WebAssembly Port!
    • This is still experimental: Be careful to use this.
    • Flappy example
    • Chipmunk physics engine example
      • Much faster than GopherJS version!
  • Polygon support (experimental)
    • DrawTriangles function
    • Polygons example
  • Multi monitors support
    • The window starts in the current monitor.
    • The fullscreen is done in the current monitor.
  • Faster Ogg/Vorbis decoder on browsers
    • The decoder is now Wasm and works in a Web Worker.
  • TPS (Tick per second)
    • Tick is a unit to represent logical time. TPS means how many times the game is updated in a second.
  • Automatic mipmap image creation
    • More beautiful linear filtering
• New APIs
  • Polygons
    • type DrawTrianglesOptions: represents options to render triangles on an image.
    • type Vertex: represents a vertex passed to DrawTriangles.
    • func (i *Image) DrawTriangles(vertices []Vertex, indices []uint16, img *Image, options *DrawTrianglesOptions): draws a triangle with the specified vertices and their indices.
  • TPS
    • func CurrentTPS() float64: eturns the current TPS (ticks per second), that represents how many update function is called in a second.
    • func MaxTPS() int: returns the current maximum TPS.
    • func SetMaxTPS(tps int): sets the maximum TPS (ticks per second), that represents how many updating function is called per second.
  • Vsync
    • func IsVsyncEnabled() bool: returns a boolean value indicating whether the game uses the display's vsync.
    • func SetVsyncEnabled(enabled bool): sets a boolean value indicating whether the game uses the display's vsync.
  • Package audio
    • func (c *Context) IsReady() bool: returns a boolean value indicating whether the audio is ready or not.
    • func NewInfiniteLoopWithIntro(src ReadSeekCloser, introLength int64, loopLength int64) *InfiniteLoop: creates a new infinite loop stream with an intro part.
  • Package ebitenutil
    • func DebugPrintAt(image *ebiten.Image, str string, x, y int): draws the string str on the image at (x, y) position.
  • func IsDrawingSkipped: returns true if rendering result is not adopted. Renamed from IsRunningSlowly.
  • func ScreenSizeInFullscreen() (int, int): returns the size in device-independent pixels when the game is fullscreen.. Renamed from MonitorSize.
  • func Wheel() (xoff, yoff float64): returns the x and y offset of the mouse wheel or touchpad scroll.
  • func (g *GeoM) Skew(skewX, skewY float64): skews the matrix by (skewX, skewY).
• Deprecated APIs
