Code:



--the register values like EAX and EBX can be read here.
--Changing them has no effect though
--Note: Keep in mind hexadecimal values start with 0x

if RCX == 1 then
   eax=0           -- Can I change the value of the register?
end

Right click the instruction in the disassembler -> "Change register at this location"

Right click the instruction again -> "Set/change break condition"
You can also do this in Memory Viewer -> View -> Breakpointlist

Suspend the game beforehand using the "Advanced options" window if that code might be run between setting the breakpoint and setting the condition


For anything more advanced, you should probably just set a breakpoint using Lua:
Code:
debug_setBreakpoint('game.exe+1234', function()
  if RCX == 1 then
    RAX = 0
  end
end)
