Classic: how to replace UnitCastingInfo?
 

This function does not exist on Classic :((

What is the simplest way to detect that player's character is casting a spell?

Detect of mobs or other players casting is also welcome :)

I had this problem with nUI. Took a while to figure it out but here it is ..

UnitChannelInfo(unit) doesn't exist .. but there is ChannelInfo() to get the players channel info
UnitCastingInfo(unit) doesn't exist .. but there is CastingInfo() to get the players casting info

I thought there was a way to get the targets casting and channeling info but maybe you can't get the details and I just remembered a time more recent than classic.

You can register the COMBAT_LOG_EVENT_UNFILTERED to check combat event like SPELL_CAST_START, SPELL_CAST_SUCCESS, SPELL_MISSED, SPELL_CAST_FAILED, SPELL_INTERRUPT.

But blizzard has removed the spell id in those events, so you only have a spell name and not spell rank in those event. We won't get the exactly cast duration but good enough to show the cast bar.

It works, thank you much!

Thanks, that may be how nUI dealt with it before, I'll have to look into that at some point I guess.
