Problem referencing instances from a For Each JSON loop

Not sure on the precise problem here but obviously it is managing to create the enemies first. If you slow it right down, pull the build enemy into a different function then call that function after a 'wait for previous actions to complete' on the floor function then it works.

the problem is that when objects are created, they are not added to C3's internal object lists until after the top level event that creates them.

in your sample file, that is the entire buildlevel function that starts at event 3.

that means you can not pick them yet in event 14 where you want to destroy them.

the easiest solution here is to add a Wait 0 action to event 10. That will defer running the "place enemies" loops until the end of the current tick - by then C3 has finished adding all the tiles and they can be picked the way you would expect - and destroyed as required.

No, It's not. I debugged that and you can see on the browser log that all tiles are created BEFORE starting to create enemies.

The logging occurs yes but they're not created yet so I gave you a fix to ensure they are created before trying to reference them.

So, no developments on this.

I tried crating another function to create enemies and call it at the end of the function that builds the level. It still can't reference floor tiles. Any other thoughts?

Cheers!

the wait 0 is critical to making it work. without the wait 0, the tiles will not have finished the process of being created when the CreateEnemies function is called. it is not a bug, Ashley has said it is a "feature" of the way objects gets created in Construct and to change it would cause too much trouble.

with the wait 0, the tiles will be fully created and can be picked the way you want.

I remember following that thread :)

the first function will completely execute before the second one, but since they are both called from the same top level event, the objects will not have completed the creation process.

I took your sample file and added a couple buttons - one to call the two functions without a wait, and one to call with a wait. (and a third to clear the board)

without a wait the spFloor.Count is zero, and the Pick All fails because there is nothing to pick yet.

with the wait, calling the same functions, it works just the way you expect it to work.

So you say, but I'm doing it, without the wait and it's working perfectly as it should. :)

That would only be a problem if you were calling the second function from inside the first one.

For instance. This would need a "wait":

on Start of layout:
----Call createLevel

on createLevel:
----(all code for the create level functions, positioning tiles and stuff)
----Wait 0
----Call loadEnemies

on loadEnemies:
----(all code for creating enemies and destroying overlapping tile)

on Start of layout:
----Call createLevel
----Call loadEnemies

on createLevel:
----(all code for the create level functions, positioning tiles and stuff)


on loadEnemies:
----(all code for creating enemies and destroying overlapping tile)

I'm guessing you didn't take a look at the example I posted (based on your file).

I do it the way you say should work - and it doesn't, until you add a wait. Try it - click the no wait button, then click the clear button, then click the wait button.

in the pseudo code you posted, the "On Start Of Layout" is the top level event. Any objects created by actions under it will not be pickable until all the actions in that event are complete and the next top level event starts. The functions don't count as top level events because they are called from the same "on Start of Layout" event. However, having two "On Start of Layout" events would work:

on Start of Layout - createLevel

on Start of Layout - loadEnemies

post a sample showing me that I am wrong. I don't think you can - I have seen this issue cause a lot of trouble, so fully understanding how objects are created and how the eventsheet works is really important.
