Title: [SOLVED] Spell attributes
Post by: Chase on June 18, 2014, 06:57:02 pm

So I'm trying to understand spell attributes in the spell.dbc

One spell has the first attribute column as 0x800100
That seems to be. CASTABLE_WHILE_DEAD which is 0x800000

But whats the 100 part at the end?

Flags can be combined. Each attribute has 31 unique values that can all be used at once. E.g, to combine the first two flags you would use the value 3 because 1 + 2 = 3. The 3rd unique flag is 4.

To further explain how this works, look at numbers in binary: in harrys example, he had 1 = 0b01 and 2 = 0b10 which combined is 3 = 0b11. Your value 0x800100 is 0b100000000000000100000000, thus 0b100000000000000000000000 and 0b100000000 (= 0x100) which is SPELL_ATTR0_HIDE_IN_COMBAT_LOG and SPELL_ATTR0_CASTABLE_WHILE_DEAD.

(Didn't know of any other way to show you these.)

All I get in-game is my spell with the correct Icon, I cannot cast it though. (Or its just not doing anything.)
Nothing in the combat log either.

This was a mostly Direct copy of Rocket Pack, (Even having a 100% copy, and only changing ID's did not work)

It is possible the spell ID is hardcoded in the emulator.
