From 0ba6048ad3c945e2bd1d0114b5095535c22103ce Mon Sep 17 00:00:00 2001 From: George Marques Date: Wed, 19 Apr 2023 11:10:35 -0300 Subject: Add support for static variables in GDScript Which allows editable data associated with a particular class instead of the instance. Scripts with static variables are kept in memory indefinitely unless the `@static_unload` annotation is used or the `static_unload()` method is called on the GDScript. If the custom function `_static_init()` exists it will be called when the class is loaded, after the static variables are set. --- .../scripts/runtime/features/static_variables.gd | 56 ++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 modules/gdscript/tests/scripts/runtime/features/static_variables.gd (limited to 'modules/gdscript/tests/scripts/runtime/features/static_variables.gd') diff --git a/modules/gdscript/tests/scripts/runtime/features/static_variables.gd b/modules/gdscript/tests/scripts/runtime/features/static_variables.gd new file mode 100644 index 0000000000..e193312381 --- /dev/null +++ b/modules/gdscript/tests/scripts/runtime/features/static_variables.gd @@ -0,0 +1,56 @@ +@static_unload + +static var perm := 0 + +static var prop := "Hello!": + get: return prop + " suffix" + set(value): prop = "prefix " + str(value) + +static func get_data(): + return "data" + +static var data = get_data() + +class Inner: + static var prop := "inner" + static func _static_init() -> void: + prints("Inner._static_init", prop) + + class InnerInner: + static var prop := "inner inner" + static func _static_init() -> void: + prints("InnerInner._static_init", prop) + +func test(): + prints("data:", data) + + prints("perm:", perm) + prints("prop:", prop) + + perm = 1 + prop = "World!" + + prints("perm:", perm) + prints("prop:", prop) + + print("other.perm:", StaticVariablesOther.perm) + print("other.prop:", StaticVariablesOther.prop) + + StaticVariablesOther.perm = 2 + StaticVariablesOther.prop = "foo" + + print("other.perm:", StaticVariablesOther.perm) + print("other.prop:", StaticVariablesOther.prop) + + @warning_ignore("unsafe_method_access") + var path = get_script().get_path().get_base_dir() + var other = load(path + "/static_variables_load.gd") + + print("load.perm:", other.perm) + print("load.prop:", other.prop) + + other.perm = 3 + other.prop = "bar" + + print("load.perm:", other.perm) + print("load.prop:", other.prop) -- cgit v1.2.3
