Hi there! Thank you in advance for helping me.
I created my first folded game by downloading and modifying a free existing game. But…
thought the build works on macOS and on “debug” it doesn’t work under HTML5
It’s just freeze on the splash screen, but no sound, no movement if i use command keys (Everything works perfect on other no-html5 bulds).
If i Open console i see these messages.
Can someone help me?
I really don’t know what is happening here.
Thank you,
bandian

I can’t say for sure without seeing any code, but it sounds like a script in your game is trying to force the game into fullscreen with `defos.set_fullscreen()` or `defos.toggle_fullscreen()`. As it says in the DefOS readme:
> On HTML5, this only works from `defos.on_click()` or `defos.on_interaction()`.

and the game is TimeLooper (if you’d like to check the code).
Even if i didn’t modify any code, i have this html5 issue.
Thank you so much,

I was sort of right, the game calls `data.fullscreen(self)` which in turn calls `defos.toggle_fullscreen()`, and that throws a warning in the console. But the game also has a domain lock built-in that disables input if the game is run in a browser, unless it’s on one of the websites listed [here](https://github.com/benjames-171/defold-games/blob/119846240267db22d855f0ee52b1cd8034b301df/Timelooper/main/handler.script#L7). Everything should work if you change:
```lua
if domaincheck() then msg.post(".", "acquire_input_focus") end
```
to:
```lua
msg.post(".", "acquire_input_focus")
```
in `handler.script`.
