Hi there!
This is very trivial, however the code example provided at https://ebiten.org/documents/cheatsheet.html#ebiten.RunGame is outdated as the signature of Update now takes an argument of type *ebiten.Image.
Thanks for the great documentation!
Example to compile Go compiler itself: https://github.com/ccbrown/wasm-go-playground
Hm, we will be able to offer the playground part as custom elements.

Some FPS drops were pointed out:
https://dstoiko.github.io/posts/go-pong-wasm/
So I checked the examples on the website and noticed the same frame drops especially when maintaining a key pressed on the keyboard. It’s not a critical issue but needs to be investigated further… Maybe in another post when I get some time to debug!
but hajimehoshi/ebiten#1175 should improve the situation.

Having followed the steps in the page above to embed my ebiten game into a web page with wasm, I find that the games does not have focus until clicked on. This behavior occurs on both firefox and chromium. Perhaps you could add another step in the directions to make game the focus upon load?
When you're running an app produced on windows when you have 2 different scaling options the game resizes based on what the active window is rather than what desktop it's on.
See video.. All I'm doing is switching window (not ebiten related either). Between display 1 and 2.
It seems it's basing it's internal scaling based on what the active window is. I don't often program using windows api so I can't tell you what the solution is. But some testing with another app shows that: https://docs.microsoft.com/en-us/windows/win32/winmsg/wm-windowposchanged is triggered with SWP_NOSIZE when I move a window between the two. (But not my field.)

I tried to draw a border. But the left line doesn't want to be drawn:) I think it's a bug.

sigunature must be signature
Now, if you double-click, an unexpected area is selected.
display: inline-block is to blame
Maybe due to too much memory?
From the installation page:
go run -tags=example ./examples/rotate
The command is very long and at start i though there was some problem because nothing happened. Maybe we can add a warning about this, something like "As the first compiling takes a little long time, you may wait a while." or similar.

Following the instructions didn't work (gcc missing), but I found this issue suggesting TDM GCC.
After installing TDM GCC (tdm64-gcc-5.1.0-2.exe), and opening a fresh terminal window, it ran fine.
IPA symbols are not rendered.
A lot of documents were moved to 'documents' now...

Following the instructions on this page using go1.16 windows/amd64 to install Ebiten doesn't work.
Trying to execute the following command
go run -tags=example github.com/hajimehoshi/ebiten/v2/examples/rotate
Yields the following result:
no required module provides package github.com/hajimehoshi/ebiten/v2/examples/rotate; to add it:
go get github.com/hajimehoshi/ebiten/v2/examples/rotate
Attempting to perform the command as instructed then yields this result:

%HOME% is not an official Windows environment variable (you likely meant %USERPROFILE%).
However, using %GOPATH% is more foolproof, since not everyone has their Go workspace in their user's home directory (like me). Strangely enough, %GOPATH% was automatically created after (clean) installing go1.12.3. I just had to need to change its value to point to the right directory after installation.
Oh, and the id-attributes of the page's h3 aren't unique, which is kinda sad when someone wants to link to a separate section of the page.

Regarding the page above, I understand that rotation can affect the borders between tiles when using SubImage(). However, I am importing PNGs directly to use in tiling, with no spaces around each tile's pixels on each PNG.
Before updating to 1.12, the tiles are flush against one another (I have a simple function set that places them adjacently). After updating, the tiles in my scene appear to have small gaps, making the (black) background visible between them.
I can continue to debug what's going on here, but believe that the back-end updates to 1.12 before they're sent to the GPU are causing this behavior change.
This problem may well be PEBKAC, and I could be misunderstanding some element of vector math etc. However, to reproduce this, all I have to do is change the import from 1.11.x to 1.12.x.
If there is any advice/a particular place for me to look in order to update my code and therefore be able to update the version number, I'd love to hear any and all advice! Thank you very much :)
