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
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
Now grpahicscommand saves the error and shows the error after a
while. This was good to simplify the API but was the cause to hide
some issues.
This change fixes all the errors to be returned immediately, and
buffer this in the ebiten package instead.
Fixes#971
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 make package shareable more consistent. The mutex is lock
after EndFrame and before BeginFrame, and the similar rule will be
applied at launching (BeginFrame unlocks the lock in any cases).
Instead, package ebiten queues image operations if BeginFrame and
doesn't create provisional non-shared images. This should improve
performance at launching since this reduces the number of draw
calls, especifally for creating new images.
