I only put the "health" on the family because there is no way to get to the "myhealth" on the family member, but that means all family members have the same "health" value, its global to the family and not independent to the family member.
That is incorrect.
All family members will share the variable name, however each value is separate to each instance.
Example:
Family members: Mom, Dad, Son
Family Variable: "Health" = 0
In the properties menu of:
Mom > Instance Variables > Heatlth = 90 ; Dad = 100 ; Son = 60
Event: Family gets hit by a brick; Action: subtract 20 from health
Which ever member is hit will lose 20 health relative to there own health
Lets say Dad and Son gets hit, Dad now has 80 health and Son has 40.
To get the Son's health simply request son.health
