Double function trigger bug.

Problem Description

If a function is called twice in the exact same time (by two Timers for instance), it is executed only once. The second trigger is ignored.

Expected behaviour would be to queue it somehow and execute function twice since it can behave differently based on parameters etc.

NOTE: Timers are queued if they trigger at the same time, therefore I assume that not queuing functions is not intended behaviour but a bug.

Description of Capx

On start of layout it creates two instances of "Sprite" object which has a Timer behaviour.

Starts Timer for each sprite (both exactly on 2 seconds, once).

On Timer: triggeres a function.

Function simply changes the frame of the sprite.

Steps to Reproduce Bug

• Just run the project and wait 2 seconds.

Observed Result

Only one sprite instance has frame changed.

Expected Result

Both instances should have frame changed.

It's the Timer that gets the queue. Add "For each Sprite", and you'll see the timer gets sent two Sprites at the same time.

I know that Timer is queued - it is good. That's how it should be. But the function which is called by two different timers at the same time, is triggered only once - this is not good. Should be triggered twice.

Ah that's what you mean. So it triggers with SOL. I was sure it triggers each instance separately.

Thanks a lot blackhornet!

Closing as not a bug. This does come up from time to time, but the "On timer" condition can have more than one instance picked at a time if multiple timers fire at the same time. Adding "for each" to the condition fixes it.
