ok, let's try SpaceZap


download from https://github.com/FrankRizzo890/SpaceZapBot

extract the sz.lua and make a few changes:

--local cpu = manager:machine().devices[":maincpu"]
local cpu = manager.machine.devices[":maincpu"]
local mem = cpu.spaces["program"]
--local ioport = manager:machine():ioport()
local ioport = manager.machine.ioport
local in0 = ioport.ports[":P1HANDLE"]
local in1 = ioport.ports[":P3HANDLE"]


then just put the file in your mame directory and dofile("sz.lua") from the lua console.

[MAME]> dofile("sz.lua")
[MAME]>
[LUA ERROR] in execute_function: sz.lua:194: number (global 'test') has no integer representation
[LUA ERROR] in execute_function: sz.lua:163: number (global 'test') has no integer representation


It shows a bunch of errors, but it seems to work despite them.

It seems to have something to do with reading u64 and then getting a really big number and not being able to convert to an integer possibly?


test = mem:read_u64(0x5ECE + (i * 8))
if test ~= 0 then
if (test & 0xFF) ~= 0 then


just as a test of numerical precision:
[MAME]> a=1e15+1 print(a&0x3)
1
[MAME]> a=1e20+1 print(a&0x3)
error: [string "..."]:2: number (global 'a') has no integer representation
[MAME]> print(a)
1e+20

Yeah, working now. Thanks Golden Child.

I would like some more AI's.

It's mesmerising, especially Robotron.

You're missing the r = require "robotron"

<deNiro>Are you talkin' to me?</deNiro>

I'm asking because like I posted above, everything works now, even SpaceZap that was giving me problems. My error was putting the script into the plugins folder instead of the MAME folder itself.

This is not a request thread. It's for people to either post cool scripts, or get help with specific problems.

Yeah I know this isn't a request thread. Sorry. lol
