For Each Object

Hi guys,

I'm trying to get the For Each Object event working but I am not having much success... Here is a snippet of some test code.



1. I create five sprites on start of layout, then display the sprite.count which displays 5. This is correct.

2. I then added a sub event to destroy them. It only destroys 1 sprite. The count is then displayed as 4, which is correct.

The For Each doesn't seem to iterate through all the objects. Am I misunderstanding something?

Make another event for the "For Each" statement. I think the fact that you are creating new objects in the parent event is messing up the picking.

The 'create object' action sets the picked objects to just the created object.

Sub-events inherit the parent event's picked objects, so the subevent inherits a single Sprite (the last created one).

For-each only iterates the currently picked objects, so it runs once for that last created sprite. (In this case you don't need a for-each, it has no effect - actions naturally run "for each" picked object. You only need a for-each when this built-in behavior does not do what you want.)

To fix it, make a second 'start of layout' event that just has 'wait 5 seconds' then 'destroy Sprite'. That event has a blank slate for picked objects, so all sprites are destroyed.

HI Ashley and Cow_trix,

Thanks for the help. I need to rethink my approach when implementing such functionality with Construct 2. I have much to learn...

Cheers
