Global variables #

Global variables are named variables accessible across multiple levels. This feature existed in original Half-Life and has been extended in Featureful SDK.

In addition to State (which can be On, Off or Dead) each global variable has an associated numeric integer Value.

Just like in original HL, global variables can be set and read via env_global entity. It got some new parameters in Featureful SDK.

Console commands #

To see the output of the following commands you must set developer cvar to 1 or higher.

• impulse 104 is used to output all existing global variables.
• set_global_state - set a global variable state (off, on, dead). This is for debugging purposes and it’s allowed only when sv_cheats is enabled.
• set_global_value - set a number value associated with a global variable. This is for debugging purposes and it’s allowed only when sv_cheats is enabled.
