Hi.
Yes it faster to place a object directly in a variable or action.
But if you would need to use for example 'Get Fsm Gameobject' to get a different object, you can set a state to work in sequence. (select a state, then in the state window where the actions are, right click on a empty space and select 'Action Sequence')
The difference is :
Action Sequence Disabled :
Top action start, then next action start and so on
Action Sequence Enabled :
Top action starts, then wait for action to 'Finish' then start next action.
you can also do 'Get Fsm Gameobject' in state 1 and then slider in state 2, that would work the same as Action Sequence Enabled.
but you could end up with a lot of states then
