Ebitengine - A dead simple 2D game engine for Go

ebiten's Issues

Improve drawing performance

Can we have automatic optimization?

Run on browsers (with gopherjs)

Add PushOffscreen / PopOffscreen

Self-drawing

What if x.DrawImage(x, nil)?

Simplify APIs

Now just showing an image requires about 70 lines in Go. Can I simplify APIs and perform this with less code?

Use travis

Improve GIF qualities

Or, can I introduce 'Ebiten in WebGL'?

Add 'Add' method for matrixes

Run ebiten on Ubuntu

sudo aptitude install libglew-dev

How about glfw?

ebiten.Image should implement image.Image

Add the license of the gopher image in _doc

Don't panic

Return errors instead.

Create a benchmark

Change the texture format to premultiplied alpha

Unfortunately, straight alpha can't treat well bi-linear filter (http://blogs.msdn.com/b/ito/archive/2010/07/10/what-is-the-premultilied-alpha-part-1.aspx).

Before applying a color matrix, the color should be unmultiplied (http://msdn.microsoft.com/en-us/library/windows/desktop/hh706319%28v=vs.85%29.aspx).

Additionally, we can use glBlendFunc again!

Use JavaScript for _docs examples

Add licenses to each file

Rename ImageDrawOptions -> DrawImageOptions?

Add a function to create an image from a texture

Implement CurrentCursor / IsMouseButtonsPressed for JS

Use GLFW

I don't want to use native APIs any more...

Rename go-ebiten -> ebiten

Reconsider unifying the module

Am I separating Go code into many modules?

Abolish GraphicsContext; Add methods to RenderTarget for rendering

Use go-gl

Move matrix/* to graphics/*

Less modules seems better

Rename Texture -> Image

Polish the input API

Create a page

Don't use glGet* in rendering loop

This might cause performance issues. Use a thread-local variable or something alike instead.

Add a function to generate GIF images

Works on iOS

Use image.Rectangle instead of ebiten.Rect

Unify ebiten.Image and ebiten.RenderTarget

It is because glReadPixels requires the pixel data at the farmebuffer.

Polish blocks game

• Drop blocks automatically
• Add 'level'
• Add 'score'
• Add 'gameover'

Rename *Geometry* -> *Geo*

Use VBO

Add keyboard keys

It should be possible to generate this from glfw key set.

Unify using NRGBA or RGBA

Use premultiplied alpha

Add a method to draw debug texts

Remove unneeded underscores from the file names

Prepare assets (like RPG Maker's tile sets) to develop prototypes

Add a method to render an image with a mask

Native app on Android

Use https://github.com/ajhager/webgl

Remove unneeded new-lines to obey the convension

Add variations of DrawImage like the package regexp's Find* functions

Maybe:

DrawImage(Parts)?(Geometry)?(Color)?

If 'Geometry' is not present, the location (x, y) should be given instead of a matrix.

Audio

As SNES sound system is PCM, should we do the same way? Is there any good way to develop SNES-like sound easily?

Use options instead of Draw* functions

Add drawing line or basic shapes method to Image

For debugging.

Ideally, it would be possible to develop a prototype without preparing images.
