Is it possible to remove the default function of the ESC key in the webplayer ( Turning off Fullscreen )…
If there isn’t any built in functions in Unity any ideas are welcome!
Thanks.

I’m not completely sure of this, but I think the answer to your question is no, the behavior can’t be disabled or changed (the reasoning being that it’s a security feature that shouldn’t be overridden).

I expected that. My idea for now is to use C# features to disable the ESC functionality at all. I’m exploring the topic at the moment.
Global System Hooks maybe will do the trick.

Have you tried it? I would think that wouldn’t be included in a webplayer build for security reasons. Those are the same set of API’s you use to create things such as a keylogger.

I’ve read the materials on the subject but I highly doubt that It will work in the web player.
Basically I will have to cheat the unity web player, the browser, the windows and couple of other things JUST to disable a key. That may even be considered a threat by some anti-virus software. Unacceptable for a game.
