[3.1.3] IsCurrentSpellBySpellId

[namreeb]

I was looking for a way to check if a given spell is currently being cast by the local player. After reading this thread: http://www.mmowned.com/forums/wow-me...rice-none.html I have updated the information there and come up with the following:

	  <Pattern desc="IsCurrentSpellBySpellId" pattern="\x55\x8B\xEC\xA1\xAC\xA2\xA1\x00\xA8\x01\x75\x04\x85\xC0\x75\x02\x33\xC0\x8B\x4D\x08\xA8\x01\x75\x12\x85\xC0\x74\x0E\x39\x48\x20\x74\x05\x8B\x40\x04\xEB\xEE\xB0\x01\x5D\xC3" mask="xxxx????xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />

bool CGLocalPlayer_C::IsCurrentSpell( unsigned long SpellId )
{
	typedef bool ( __cdecl * tIsCurrentSpellBySpellId ) ( unsigned long );
	tIsCurrentSpellBySpellId IsCurrentSpellBySpellId = ( tIsCurrentSpellBySpellId )gpWoWX->GetFindPattern()->GetAddress("IsCurrentSpellBySpellId");

	return IsCurrentSpellBySpellId(SpellId);
}

Thanks for sharing

Thanks for sharing. The pattern is quite big and I would recommend shortening it a bit.

[namreeb]

Yah, the pattern is actually the entire function. I had to lengthen it quite a bit (though probably not this much) because there is another very similar function.

Pattern the bit that is different and then subtract the amount of bytes to the start of the function
