Cvars

Variables you can set via the command line:

./dragonruby game_folder --set veriable.name value

Accessing Cvars

args.cvars['variable.name']

Available methods:

• name
• value
• value= (only for non-locked variables)
• type
• description
• locked: Variable can only be set on application start via the --set flag, not during runtime

Register Cvars

$gtk.register_cvar varname, description, type, default_value

• type: :string, :int, :uint, :bool

Default Cvars

$args.cvars.each do |name, var|
  puts "#{name}: #{var.value} (#{var.description}. Type: #{var.type}. Locked? #{var.locked})"
end
