Console Commands

Command
Description

wire_expression2_model
Manually changes the expression's model

wire_expression2_reload
Reloads all E2 extensions, useful for debugging your own extensions. Keep in mind that client-side files will be taken from gmod's cache in multi-player mode.

wire_expression2_debug 0/1
Toggles debug mode, which shows info that might be useful for the developers. You need to do "wire_expression2_reload" after changing for this to have any effect.

wire_expression2_extension_enable
Enables the specified extension.

wire_expression2_extension_disable
Disables the specified extension.

wire_expression2_unlimited 0/1
Enables/disables performance limiting.

Note: Most E2 addons do not register themselves as extensions and thus cannot be turned on or off with the above commands. A notable exception is the Prop-core extension, which is disabled by default.

Also, you must run wire_expression2_reload in order for enabling/disabling extensions to take effect.
