Trying to spawn coins using a custom action or a function.

Hi. I have a level setup that spawns items like keys and coins, but for some reason it doesn't always spawn the coins when the action (or function) is called. Custom actions work for spawning the keys everytime but not the coins... is it because there are too many of them (450+) so it fails to execute?

When I spawn the coins using "on start of layout" they spawn every time without fail, but I would like to have confidence that I can rely on actions and functions to work correctly so I want to know if I'm doing something wrong. Thanks.

* scene_controller action 'Spawn Score'

----+ System: Pick all Score_Spawner

-----> Score_Spawner: Spawn obj_coin on layer "a_objects" (image point 0, create hierarchy: False)

Edit: It seems to happen because I start the 'Spawn Score' action at the end of another action (in a chain of actions). Calling the custom action from 'on start of layout' seems to work fine too.

Here's the full group for reference -

[Item Spawning]

** sorry ignore that 'spawn score' in the first 'on start of layout event, I forgot I added that when I was testing other solutions. **

I think the problem is that you are picking a random spawner first, and then checking if it has not spawned a key. If the first condition picked the spawner which has already spawned a key, the whole event won't run. You need to swap the order of these conditions in every event.

Also, "Wait for previous action" should not be used like that - you need to remove them or replace with "Wait 0" if you want to wait to the end of the tick.
