Constants

Declare named global variables here to use them from other command lists, [Key] bindings and [Preset]s. Named variables are namespaced so that any included ini files can use their own without worrying about name clashes:

global $my_named_variable = 0.0

Mark a variable as persist[ent] to automatically save it to the d3dx_user.ini on exit or F10 (config_reload). Use Ctrl+Alt+F10 (wipe_user_config) to discard persistent values:

global persist $some_persistent_variable = 1

Set the initial value of "IniParams" variables, which are accessible from within shaders, but they are not namespaced and too many can become unwieldy:

y = 1.0
z = 1.2
w = 2.0
y1 = 3

For more information about variables, please refer to the Variables section.

global

The necessary modifier when declaring a global variable. Variable rules can be found here. Also, note that global variables are only declared within the Constants section.

[Constants]
global $a_global_var = 1

local

The necessary modifier when declaring a local variable. Variable rules can be found here. Local variables can be declared anywhere needed for calculations. However, it is uncertain how GIMI handles the recycling mechanism for local variables. At least for now, local variables are not seen frequently.

[AnySection]
local $i = 0

persist

The necessary modifier when declaring a persistent variable. Variable rules can be found here. This modifier is only used for global variables. Once declared, the variable will persist(throughout gameplay sessions) and be stored in d3dx_user.ini. It will only be reset when you use Ctrl + Alt + F10.

[Constants]
global persist $a_persist_var = 1
