#includeIn this example, we first retrieve the ConVar variable "myVar" using the FindVar function. We then use the GetBool function to retrieve its boolean value, which is stored in the myBool variable. Finally, we use an if/else statement to check the value of myBool and print a message accordingly. The package library for ConVar GetBool is the Source Engine library, which is a game engine designed by Valve Corporation for use in their various video game titles.#include "engine/convar.h" void main() { ConVar* myConVar = cvar->FindVar("myVar"); bool myBool = myConVar->GetBool(); if (myBool) { printf("myVar is true"); } else { printf("myVar is false"); } }
