◆ take_side()

bool wesnothd::game::take_side ( player_iterator user )

private

Figures out which side to take and tells that side to the game owner.

The owner then should send a [scenario_diff] that implements the side change and a subsequent update_side_data() call makes it actually happen. First we look for a side where save_id= or current_player= matches the new user's name then we search for the first controller=human or reserved side.

Parameters

user	The player taking a side.

Returns: True if the side was taken, false otherwise.

◆ level_

simple_wml::document wesnothd::game::level_

private

The current scenario data.

WRONG! This contains the initial state or the state from which the game was loaded from. Using this to make assumptions about the current gamestate is extremely dangerous and should especially not be done for anything that can be nodified by wml (especially by [modify_side]), like team_name, controller ... in [side].

FIXME: move every code here that uses this object to query those information to the clients. But note that there are some checks (like controller == null) that are definitely needed by the server and in this case we should try to modify the client to inform the server if a change of those properties occur. Ofc we shouldn't update level_ then, but rather store that information in a separate object (like in side_controllers_).
