The initial settings for a game, used to create the map in RM & tosetup the simulation, are named InitAttributes in the C++, but generally referred to as GameAttributes in the JS GUI. This renames the latter to the former to avoid confusion, since these settings are immutable once the map starts, so InitAttributes is more accurate. Differential Revision: https://code.wildfiregames.com/D3705 This was SVN commit r25083.

* Cheat prevention:
|
|
*
|
|
* 1. Ensure that the host cannot start the game unless all clients agreed on the game settings using the ready system.
|
|
*
|
|
* TODO:
|
|
* 2. Ensure that the host cannot start the game with InitAttributes different from the agreed ones.
|
|
* This may be achieved by:
|
|
* - Determining the seed collectively.
|
|
* - passing the agreed game settings to the engine when starting the game instance
|
|
* - rejecting new game settings from the server after the game launch event
