How to detect if a spell is usable?

[phthegreat]

HI!
Generally speaking, distance, mana and cooldown determine if a spell is usable.
I learn from this thread
http://www.mmowned.com/forums/world-...cooldowns.html
that there is a list of active cooldowns. But only a list of coldown isn't enough.
And I have set bps at function IsValidSpell and lua_IsUsableSpell, but nothing happened.
So my question is: is there a way to detect if spells are usable?
Thanks a lot.

None of these APIs can tell if a spell is usable

Either use this lua function directly or revers it to find out how it works and reimplement it.
It does take into account all conditions, such as mana rage energy and ofc that you've got a valid target.
Your first post is utter bullshit, if you want to trigger a breakpoint on a lua function you'll have to actually call it...

I think it is not me but the addon that call the lua function to trigger the bp. But thank you all the same!
