Spawning actors with different attributes

G'day people, I have had a search but can't find the answer to this problem. I have an actor(ball) that when touched I want it to spawn other actors(balls) but smaller. I'd rather not have to have multiple different size balls and that seems a bit silly.

Is it possible to spawn the same actor type with different attributes?

Thanks in advance.

    I think I'll just have to make 3 different sized balls. Or I could just spawn them and change the size immediately, but I think you'd notice that.

    When you spawn an actor , it gives you the option to control the Direction /rotation of the actor.

    You can spawn your actor and set the direction of the spawned actor to be random(1,3)

    if self.rotation = 1
    change color to blue
    change the rotation back to 0 ( this will change quick and you will not notice that the actor was rotated the second it was spawned)

    if self.rotation = 2
    change color to yellow
    change the rotation back to 0

    if self.rotation = 3
    change color to pink
    change the rotation back to 0

    You can extend this , so for example

    if self.rotation = 1
    change self.redball to true
    change image to red ball image
    change self.rotation to 0

    if self.redball is true
    { do whatever you want }

    Do the same for the other ball

    if self.rotation = 2
    change self.Greenball to true
    change image to green ball image
    change self.rotation to 0

    if self.Greenball is true
    { do whatever you want }

    I think adding seperate actors would be better , it will reduce complications in the long run.

    You can also "pass" attribute values to spawned actors through the use of game attributes. These rules will spawn three balls of different sizes...

    In the spawner actor:

    Change attribute game.newSize to 80
    Spawn actor [ball]

    Change attribute game.newSize to 60
    Spawn actor [ball]

    Change attribute game.newSize to 40
    Spawn actor [ball]

    In the spawned [ball] actor:

    Change attribute self.size.Height to game.newSize
    Change attribute self.size.Width to game.newSize

    If you want to spawn smaller sized balls you can also do this

    create a boolean self attribute name it parent set it to false

    if self.parent = false
    change self.size.width to random number
    change self.size.height to random number ( or width to maintain the same size )

    if touch is pressed spawn actor

    now place your actor on the scene , double click the actor in the scene , set its self.parent to true manually by ticking the boolean , so now its the parent and it wont be affected by the rule ( to change the size) , while the others will have self.parent set to false by default so they would change size randomly.

    Hey guys, sorry I never thanked you for your suggestions. I did have a play with what you said, and it works (as you knew it would:) but I had already set it up with the different sized balls. Decided since I will be using them elsewhere, it is just easier I think.
    Thanks again though, taught me to be a bit creative in my thinking.
