How to find out which #RANDOMEFFECT was used?

[nexus]

Hi,

I tried to search the doku and also this forum but could not find the answer to my question.

I am using HideLayerFX & ShowLayerFX with type=#RANDOMEFFECT and async=True. Then I am using AsyncDrawFrame() to show/hide some image/brush.

However, sometimes

Code: Select all

GetAttribute(#ASYNCDRAW, id, #ATTRNUMFRAMES) 

returns a 0. I am wondering how that can be and which RANDOMEFFECT causes that?

Any clue?

returns a 0. I am wondering how that can be and which RANDOMEFFECT causes that?

Good question. Normally that shouldn't happen. Have you got an MCVE that demonstrates the issue?

Not yet. Actually, I could not re-produce it with Hollywood 10. However, I discovered it the first time (and afterwards regularly) with Hollywood 8. I programmed a workaround by re-calling the Show/HIdeLayerFx until the number of frames is >0.

That's why I asked how to find out which effect was chosen

I meanwhile also do not call #RANDOMEFFECT anymore but copied all possible FX from docu and re-implemented the random functionality including the possibility to map the FX Constant to a human readable string. So, when switching back to HW8, I should be able to see which FX is causing the issue

But first, another week of real work instead of fun -- unfortunately

Cheers,
Tom

Could be a bug in Hollywood 8. There were quite a number of fixes in the transition effects library in preparation for the Designer 6 and 7 releases.

Uh, I got this now once for HW10, too. Pretty hard to reproduce though. If I can find a MCVE, I will post it here

cheers,

Thanks, clearly a bug. Will be fixed.

Code: Select all

- Fix: Querying #ATTRNUMFRAMES for an #ASYNCDRAW object of the #SCROLLXXX effect group always returned 0
