Configuration Variables

Much of the the configuration of Ren'Py is done using configuration variable. These variables, when assigned in a python block, change the behavior of the interpreter. As configuration variables aren't saved, and many need to be set before the GUI initializes, it makes sense to set all configuration variable inside init blocks. An example setting of variables is:

init:
    $ config.screen_width = 640
    $ config.screen_width = 480
