Custom Subaction Format
Enable Reflect: FF01RRRR DDDDSSSS XXXXYYYY
Disable Reflect: FF000000


FF = Reflect Subaction Command Byte
00/01 = Used by the function to determine whether to enable the reflect hitbox or disable it. Keep this 01 for enabling and 00 for disabling.

RRRR = Radius Size, use the upper 2 bytes of a single floating point representation*
DDDD = Damage Multiplier, use the upper 2 bytes of a single floating point representation*
SSSS = Projectile Speed Multiplier, use the upper 2 bytes of a single floating point representation*
XXXX = X Position, use the upper 2 bytes of a single floating point representation*
YYYY = Y Position, use the upper 2 bytes of a single floating point representation*

*Use the converter here, http://www6.uniovi.es/~antonio/uned/ieee754/IEEE-754.html



Example in Crazy Hand:

Code:
#r5 = subaction RAM location

lwz    r5,0x8(r4)                #load current subaction RAM location
lbz r14,0x1(r5)            #get enable/disable byte
cmpwi r14,0x0            #check if 0
beq disableReflect            #branch to disable reflect


enableReflect:                #a lot of this code was copied from the game's createReflectHitbox function
mr r7,player                #move player block pointer into r7
li    r6, 1
load r14,0x8006da48                 #function that points to blr
