Plugin MAME

Thu Aug 31, 2017 8:47 am

Hello,

On lua script (plugin MAME), i try to understand the logic. I create a simple plugin to write a file with “test”. (no wiki :( )

Code: Select all

-- test.lua -- by XXXX -- -- local exports = {} exports.name = "test" exports.version = "1.0.0" exports.description = "Test" exports.license = "NewQuest" exports.author = { name = "XXXX" } local test = exports function test.startplugin() local test_path = "test"; local function get_file_name () local r; if emu.softname() ~= "" then r = test_path .. '/' .. emu.romname() .. "_" .. emu.softname() .. ".txt"; else r = test_path .. '/' .. emu.romname() .. ".txt"; end return r; end emu.print_verbose("test: init") emu.print_verbose(get_file_name()) local output = io.open(get_file_name(), "wb"); if not output then -- attempt to create the directory, and try again lfs.mkdir( test_path ); output = io.open(get_file_name(), "wb"); end output:write("test"); output:close(); end return exports
this plugin don’t work
Where is display “emu.print_verbose” ?
On plugin.json, option “start” : true/false What's the point?
If i set start:true on my test plugin, MAME can not play games
If i set start:false on my test plugin : it’s ok but a file don’t created
And if start:false when plugin is executed ?

Thanks for you help

Where is display “emu.print_verbose” ?
=> I don't find but with print function, it's OK

On plugin.json, option “start” : true/false What's the point?
=> it's OK : if true : auto start plugin :)

If i set start:true on my test plugin, MAME can not play games
=> simply a error on my script, use emu.romname() too early

Thanks

I update my questions :

- Where is display “emu.print_verbose” ?
- Are there events ? rom launched for example ?

Thanks

can help other people :

it is an example of a code that works, with a action on start of a game (inspired by hiscore plugin)

Code: Select all

-- test.lua -- by XXXX -- -- local exports = {} exports.name = "test" exports.version = "1.0.0" exports.description = "Test" exports.license = "XXX" exports.author = { name = "XXX" } local test = exports function test.startplugin() print('=>OKOK'); print("test: init") local last_write_time = -10; local function tick () if emu.time() > last_write_time + 5 then print("test:tick"); last_write_time = emu.time(); end end local function reset() print("test:reset"); end emu.register_start(function() print("Starting " .. emu.gamename()); last_write_time = -10 end) emu.register_frame(function() tick(); end) emu.register_stop(function() reset() end) emu.register_prestart(function() reset() end) end return exports
