Does actor self-destruct when off of the screen?

HappyKat78

Hi All,

It looks to me like an actor automatically destroys itself when off the screen by a certain distance or for a certain amount of time. Is this right and where can I learn more about this? I tried searching for this but couldn't locate anything. I want to destroy an actor when it's left the scene for ~3 seconds and I have a way of doing this using a separate actor that counts when the main actor is off-scene (and if it's 3 seconds it initiates levelfailed), but I just want to make sure I'm doing this in the most efficient way.

Thanks

yes, if an actor goes outside the screen area to far it will destroy itself.

Do you know how far it must go outside the screen before Saladcide occurs ? It'd be good to know.

based on a standard iphone screen size it should destroy itself around these co-ordinates

Actor X = -504 to -509
Actor X = 980
Actor Y = 822 to 827
Actor Y = -502 to -507

Thanks for this. Is there a way to tell when the game has automatically destroyed the actor in this way? I'm thinking a workaround could be to have the actor control a global attribute in some way which would obviously stop when the actor is destroyed but that would require a timer checking it every second, so wondering if there is a more simple way?

actually the sceneSize affects the destruction point

yes … you can make that destruction control another attribute … but you need to constrain another gameAttribute to the moving Actor's X or Y position
then when that gameAttribute ≥ the destruction point … changeAttribute the on you want it to change
(this Rule needs to be in a controlActor)

you can monitor what is going on with DisplayText behaviors in other actors

Thanks for the info. I decided to go with a boolean that triggers when the actor isn't over the scene and then a timer will count for 3 seconds. If the actor doesn't overlap with the scene within those 3 seconds it assumes it's destroyed or not coming back so triggers the levelfailed attribute. This seems to work well.
