#2, appears that you want to set a variable and then trigger an event on that gameobject? if so, apply these two actions.
Gameobject1, apply the Set FSM INT (for example)
gameobject = specify gameobject
**change from none to your gameobject
FSM name = FSM
Variable Name = Variable Name
Set Value = 10
Send Event by Name
Event Target = Game Object FSM
GameObject = Specify Game Object
**change from none to your gameobject
FSM Name = FSM
Send Event = Enter the name of the event you wish to send. Remember that this must be an available transition for the current state, otherwise it will not work.
