What I still don't understand is why an object, that obviously exists, at the same time is not pickable.

I think this is about the first time this has been addressed, at least in this detail, and its awesome.
While we have your attention Ashley do you think C2 could be designed at least as far as the gui goes to show whats going on?
For example, conditions, and actions get muddied up a bit when we start to think of it as an event, instead of its separate parts.
If we could have a different numbering system, where all conditions, actions..."sub- conditions?", and "sub- actions" were given their own title, like:
(1) condition| (1a) action
-(1s1) sub condition| (1as1) sub action
(2) condition| (2a) action
-(2s1) sub condition| (2as1) sub action
-(2s1) sub condition| (2as1) sub action
--(2s2) sub condition| (2as2) sub action
.......ehh ok that might be a bit much, but perhaps a graduated color scheme for subevents, and at least some kind of marker for the first top level event of each new event.]]> Sun, 30 Jan 2011 23:18:18 +0000 http://www.scirra.com/forum/picking-problem_topic41776.html http://www.scirra.com/forum/picking-problem_topic41776_post257715.html#257715 Author: Ashley

Thanks for the picture R0J0, that sums it up nicely. For the record, it used to be that it wouldn't be pickable until the next tick - a fix a few versions ago made it the next top level event, but due to the design of the engine, it's very tricky to make it available in subevents (where Destroy is in your diagram).]]> Sun, 30 Jan 2011 22:46:17 +0000 http://www.scirra.com/forum/picking-problem_topic41776.html http://www.scirra.com/forum/picking-problem_topic41776_post257714.html#257714 Author: R0J0hound

In an effort to nail down the rules:

1. When an object is created it becomes the only picked object of that type for the actions below it and in sub-events of the event the object was created in.
2. The new object can't be picked in the following events with the same nesting level as the event it was created in (unless it was created in a top level event).
3. Once a new toplevel event is reached the new object can be picked like normal.

To illustrate:

You can, if the action is associated with the object.
You can do that if its within that particular top tier event, or its subevent.
Note a top tier event doesn't necessarily have to be the first event.
A top tier event can be a condition's sub event.
Its basically the same as the first event if its not associated with a preceding event.

Does that make sense?[/quote:3258oobi]
newt, did you try my example? Because all you say is tested in my example and it does NOT work.

I, too, know what I am saying, although it seems to be ignored...]]> Sun, 30 Jan 2011 20:46:02 +0000 http://www.scirra.com/forum/picking-problem_topic41776.html http://www.scirra.com/forum/picking-problem_topic41776_post257693.html#257693 Author: newt

[quote="PixelRebirth":3v5zn9nb]
I do think Ashley said what he said for a reason. Look at this overly simplistic example:

[url:3v5zn9nb]http://dl.dropbox.com/u/2306601/blinky.cap[/url:3v5zn9nb]

When you press X, a Sprite is being created at the center of the screen. But with the current event order, you won't see anything. It's immediately being destroyed by the second event. However if you switch the event order, the sprite briefly appears before being destroyed. Which means it already existed and could be picked before the next tick - according to my very own logic. Otherwise it shouldn't have blinked when you switch the order. Unless something is going on I'm not getting, which is always a good chance. Still Ashley said what he said! [/quote:3v5zn9nb]
Thanks for the example
I understand the logic and agree with the creation. But, well, why can't I access a pv then until the next tick? Doesn't make sense.

EDIT: All the top level and subevent explanations, they don't make sense. I was following your logic (that I feel is correct, if I can see the object it must exist) and played around. Now look at this example. The sprite is created in a subevent and immediatly exists - but the pv is not accessible. I get a headache ]]> Sun, 30 Jan 2011 08:48:15 +0000 http://www.scirra.com/forum/picking-problem_topic41776.html http://www.scirra.com/forum/picking-problem_topic41776_post257679.html#257679 Author: newt

[code:37vuf9xt]+ System: Start of layout
-> Sprite: Rotate 90 degrees clockwise
-> Sprite: Set filter to
[/code:37vuf9xt]

Nothing wrong with another start of layout, after all events are run in order, even in start of layout.
Speaking of...
From my perspective both Ash, and Rojo are correct.
The second, third, and fourth events are subevents, and have nothing to do with each other.
If the second, and third were somehow picked in the top tier then the 4th would.
But your dealing with multiple instances, and you have to come at it from the left side, or conditional picking of the equation.

Edit:
Rojo beat me to it. ]]> Sun, 30 Jan 2011 04:11:53 +0000 http://www.scirra.com/forum/picking-problem_topic41776.html http://www.scirra.com/forum/picking-problem_topic41776_post257678.html#257678 Author: R0J0hound

Hey cool,
Thanks PixelRebirth, I was not aware that created objects could be picked in the next toplevel event. That will make my eventing easier than waiting till the next tick. My assumption came by trial and error, but obviously I didn't try everything.

So here's a better solution to the initial problem:
Instead of rotating the objects the next tick, just add another toplevel "Start of Layout" event.
