-Usage of this directive will result in a size increase, and a very low performance decrease, but should not in any case alter how the existing code functions. (if it does, please report that as a bug)
-
-The following obfuscation methods are applied:
-
-- Rule filling: 2500 empty rules are inserted, making it impossible to view the gamemode within the workshop UI. It must be copy-pasted to be able to be edited (you can then apply various anti copy-paste integrity checks).
-- Name obfuscation: all rule titles and comments are removed, and all variable/subroutine names are replaced with a combination of capital i and lowercase L.
-- String obfuscation: characters in custom strings are replaced with special characters that display in Overwatch, but not text editors.
-- Constant obfuscation: some constants, such as heroes or maps, are replaced with other values that compute to the original value.
-- Inspector obfuscation: the inspector is disabled, and all inspector-related actions are removed.
-- Copy protection: the gamemode will break upon copying it via text. It is highly recommended to enable constant obfuscation to greatly strengthen this protection.
-
-To save elements, it is possible to specify methods to disable, by prefixing them with \`no\`. For example, \`#!obfuscate noRuleFilling noConstantObfuscation\` will disable rule filling and constant obfuscation, which is useful if the obfuscation adds too much elements.

+
+Usage of this directive will result in a size increase, and a very low performance decrease, but should not in any case alter how the existing code functions. (if it does, please report that as a bug)
+
+The following obfuscation methods are applied:
+
+- Rule filling: 2500 empty rules are inserted, making it impossible to view the gamemode within the workshop UI. It must be copy-pasted to be able to be edited (you can then apply various anti copy-paste integrity checks).
+- Name obfuscation: all rule titles and comments are removed, and all variable/subroutine names are replaced with a combination of capital i and lowercase L.
+- String obfuscation: characters in custom strings are replaced with special characters that display in Overwatch, but not text editors.
+- Constant obfuscation: some constants, such as heroes or maps, are replaced with other values that compute to the original value.
+- Inspector obfuscation: the inspector is disabled, and all inspector-related actions are removed.
+- Copy protection: the gamemode will break upon copying it via text. It is highly recommended to enable constant obfuscation to greatly strengthen this protection.
+
+To save elements, it is possible to specify methods to disable, by prefixing them with \`no\`. For example, \`#!obfuscate noRuleFilling noConstantObfuscation\` will disable rule filling and constant obfuscation, which is useful if the obfuscation adds too much elements.
