Fightcade Lua Hotkey -

FightCade's emulator exposes a Lua API. To make a "hotkey," you generally need three things:

Here is an interesting piece of code that functions as a "Combo Breaker" or "One-button Special" script. This script allows you to map a complex combo (e.g., Quarter Circle Forward + Punch) to a single keyboard key. fightcade lua hotkey

Here’s the important part: Fightcade does not police Lua scripts. You could write an auto-block script that reads enemy position memory and blocks low every time. That would be cheating. Most players and lobbies consider macros for difficult but legitimate techniques (like pretzels in Garou) as gray-area, and anything that reads game state (memory reading) as outright cheating. FightCade's emulator exposes a Lua API

My rule of thumb:

Respect the lobby. Ask opponents if they’re okay with macros. Keep the spirit of the arcade alive. Here is an interesting piece of code that

local invincible = false
function toggle_inv()
  invincible = not invincible
  if invincible then
    print("Invincible ON")
  else
    print("Invincible OFF")
  end
end
function frame()
  -- assume health at address 0x1234 (example; find actual address per game)
  if invincible then
    memory.writebyte(0x1234, 0x99)
  end
end
emu.registerhotkey(1, "Toggle Invincibility", toggle_inv)
emu.registerframecallback(frame)

If you want to map a credit insert to a keyboard key that isn't in the standard config:

if input.get().F5 then
    -- Simulate Coin 1 press
    joystick.set(0, "Coin", true) 
end

You can save this as a .lua file and load it into FightCade (typically via the console or the LuaEngine menu).

-- FightCade Simple Macro Hotkey Example
-- NOTE: Key codes vary. Standard keyboard 'A' is usually 65 in ASCII, 
-- but emulators often use specific input libraries (like DirectInput).
local input = require("input") -- Access to input registers
local key_mem = 0x100 -- hypothetical memory address for P1 inputs (game specific)
-- Define a simple function to check if a key is pressed
-- This relies on the emulator's specific API for key registration
local function isKeyPressed(keyCode)
    -- In FBA Lua, we often check specific memory addresses or 
    -- use the 'input' module if available. 
    -- This is a placeholder logic for demonstration:
    return input.get()[keyCode] 
end
-- Main Loop
while true do
    -- Check if the "Tilde" key (`) is pressed
    -- We use a generic key check here; FightCade often uses DirectInput scancodes.
    local keys = input.get()
if keys["tilde"] then
        -- EXAMPLE: Perform a Hadouken (QCF + Punch)
        -- Logic: Down -> Down-Forward -> Forward -> Punch
print("Hotkey Triggered: Hadouken!")
-- Step 1: Hold Down (60 frames usually too long, let's do 4-5 frames)
        -- Note: Writing to memory requires knowing the game's specific input RAM address.
        -- Here we simulate writing to a generic input port.
-- Hypothetical write (pseudo-code logic for FBA)
        memory.writebyte(key_mem, 0x02) -- 0x02 = Down (Check game specific hex values)
        emu.frameadvance()
-- Step 2: Down-Forward
        memory.writebyte(key_mem, 0x06) -- 0x06 = Down+Right
        emu.frameadvance()
-- Step 3: Forward + Punch
        memory.writebyte(key_mem, 0x04) -- Right
        memory.writebyte(key_mem_punch, 0x01) -- Punch
        emu.frameadvance()
-- Release
        memory.writebyte(key_mem, 0x00)
        memory.writebyte(key_mem_punch, 0x00)
-- Debounce: Wait until key is released to prevent spamming
        while keys["tilde"] do
            keys = input.get()
            emu.frameadvance()
        end
    end
-- Always advance the emulator frame at the end of the loop
    emu.frameadvance()
