this && alive unitName
-Put the above line in the Condition field of a trigger which is activated by...Blufor 'Present' for example
& the trigger will only activate if the passed unit is alive.
***However you could achieve the same result by grouping a Unit to a trigger (condition field > 'this') & setting the activation field of the said trigger to Vehicle||Group Leader||Any Group Member||etc, 'Present'. Since im figuring that the unit has to be alive to activate the trigger in this case, the trigger will activate because - by the Unit being present, the Unit is alive....however, if you want the trigger to activate when the Unit is dead simply change the activation field to 'Not Present", becasue when the Unit is dead within the trigger he is then 'Not Present'...obviously because he is Dead > Not Alive, therefore > Not Present.
