This change adds an optional function Draw to the Game interface.
With Draw function, the game logic and rendering are separate.
There are some benefits:
* The API is clearer and easier to understand.
* When TPS < FPS, smoother rendering can be performed without
changing the game logic depending on TPS.
* Porting to XNA, which has separate functions Update and Draw,
would be a little easier.
Draw is optional due to backward compatibility. Game interface was
already used before v1.11.x in mobile packages, and adding a
function would break existing code unfortunately. Then, we adopted
switching the behavior based on whether Draw is implemented or not
by type assertions.
IsDrawingSkipped will always return false when Draw is implemented.
Fixes#1104
Now a window can be floating with SetWindowFloating, the functions
that have suffix 'IsBackground' seems misleading. However, we
cannot rename them due to backward compatibility. Then, let's add
aliases and revisit them when updating the major version of Ebiten.
Fixes#1102
This means that the whole offscreen is cleared correctly.
This change is a little breaking change: SetScreenSize or other
functions no longer works on ebitenmobile. Use Layout instead.
Fixes#1019
This change introduces the new APIs RunGame, WindowSize and
SetWindowSize. These new APIs hides the notion of 'scale', and is
more flexible with the outside size change. This means that we can
introduce a resizable window.
This change also adds -legacy flag to examples/windowsize. If the
flag is off, the new APIs are used.
This change deprecates these functions since the notion of 'scale'
is deprecated:
* ScreenScale
* ScreenSizeInFullscreen
* SetScreenScale
* SetScreenSize
Fixes#943, #571
Updates #320
This change forces Ebiten apps on browsers 'fullscreen' mode.
After this change, 'scale' value is no longer used on browsers.
Note that this breaks backward compatibility, but as long as the
game works in an iframe, this should not be problematic.
Fixes#960
