Fighter Cleric Usability Flag

Greener

I'm trying to allow fighter clerics to use axes, but I'm struggling with some of the code any thoughts?
COPY_EXISTING_REGEXP GLOB ~ax.*.itm~ ~override~ PATCH_IF (SOURCE_SIZE > 0x71) THEN BEGIN READ_BYTE 0x2f "use" WRITE_BYTE 0x2f ("%use%" BAND "0x4000") END BUT_ONLY_IF_IT_CHANGES

This is the code that DoF uses... it makes cleric have the same restriction that fighters has (what means none). A think that adapted for your needs it would be

COPY_EXISTING_REGEXP ~ax.*.itm~ ~override~
	PATCH_IF (SOURCE_SIZE > 0x71)     BEGIN
		READ_LONG	0x64	       ex_off
		READ_SHORT	0x68	       glob_ex
		FOR	(j = 0; j < glob_ex; ++j)	BEGIN
			READ_SHORT (ex_off + (j * 0x38) + 0x0002) location
			PATCH_IF location = 1 BEGIN
			WRITE_BYTE 0x1e (THIS BAND 0b11111111)
			WRITE_BYTE 0x1f (THIS BAND 0b00001000)
			SET j = glob_ex
			END
		END
	END

Here's my take on the code. It should also include custom axes, as well as axes made by Beamdog, as these don't always use the ax prefix:

COPY_EXISTING_REGEXP GLOB ~^.+\.itm$~ ~override~
	PATCH_IF (SOURCE_SIZE > 0x71) BEGIN
		READ_BYTE 0x1f usability2	//second byte of the usability flags, so bits 8 to 15. 
		READ_BYTE 0x1c category	//Item Type

		PATCH_IF (category = 25) BEGIN //Checks if the item is an axe, which is category 25. Another way of identifying if an item is an axe is by checking the proficiencies, but these should be equivalent
			WRITE_BYTE 0x1F (usability2 & 0b10111111)  //Rewrites usability2 and sets its BIT 6 to 0
		END
	END
BUT_ONLY_IF_IT_CHANGES

If you want to allow axes for FMC too, replace 0b10111111 with
0b00111111, to also set bit 15 (which matches FMC) to 0.
