hah, i think i got it know! maybe i am an idiot, but here is the point where ive got confused:
[quote:n2acthbj]If you add an instance variable to a family, all the object types in the family inherit the instance variable. For example, adding the instance variable health to the family Enemies in the above example will mean BladeEnemy, BugEnemy, CrescentEnemy, FighterEnemy, SaucerEnemy, ScytheEnemy and SlicerEnemy all gain a health instance variable. It will also appear in the editor alongside each object's own instance variables.
As you can see the object astroid_iron is in the family RadarObjects. But in the editor it has neither of the instance variables from RadarObjects.
[attachment=0:n2acthbj][/attachment:n2acthbj]
so i assumed that the instancevariable from the family doest count for every single object, but just one time for the whole family. and if i set it to another value all values get changed for every object. if it count for each object in a single way and is editable for each single object seperatly it does exactly what i want it to do
Is this an roor in the discription, a bug or am i still missing something?
found it: on the propertys on the left site of construct it shows up... man thank you so much again
