Update: Replay recording!

At last, I’m done with replays! This feature has certainly taken more time and effort to complete than what I initially thought it would. For those curious, some form of per-room player ban is next on the list.

Changes:

• Added a rec button, press it once to start recording, press it again to stop and save the recorded gameplay as a .hbr file!
• Added a “Replays” button to the room list, use this to load previously saved replays.
• Added a ping graph option, enabling it will display a graph of your ping history (Doesn’t show if you are the host).
• Added a new URL parameter which lets users link to replay files. Try it! Detailed explanation below.

Replay links explained (gets a bit technical):

A replay link has the following format:

“http://www.haxball.com/?replay=#”

is currently 0, but this number will change every time a new version of HaxBall is released. HaxBall replay files (.hbr) have got this number stored in their first 4 bytes (as a big-endian unsigned integer), which should be useful if someone wanted to implement some sort of HaxBallReplay-Tube (wink wink ;).

is the URL of the .hbr file to load.

Example: http://www.haxball.com/?replay=0#http://www.haxball.com/demo.hbr

There’s also a small catch, because of Flash security policies your file host needs have a crossdomain.xml policy file allowing haxball.com (and haxball.appspot.com) to read files from it.
