Hi,
ok, so yes, the api will give you access to all the global variables, per type.
Within the context of an action, you can query:
FsmVariables.GlobalVariables.GetFsmBool("my global bool");
this will give you a pointer to that global boolean "my global bool" and then you can set or get its value
If you need a working example or a custom action, let me know, so that you can get started.
bye,
Jean
