Hello all,
I'm planning on making my first TAS. My goal is to make one in which I complete Very Hard mode of the classic puzzle game "Panel de Pon" as fast as possible. Although I'm debating this, I am hoping to accomplish this all with a Lua bot and zero human input. I want this for a multitude of reasons:
- The bot could probably run on multiple versions of the same game, so long as the memory addresses are slightly modified.
- Improving on the speed would be a lot simpler than redoing the entire game.
- It could serve as an educating experience for both myself and the TAS community.
- AI is fun!
In its current form, it will navigate to VS, select Very Hard mode, start the match, and move to a particular location on the grid. Also, it defines a function "cursor" that can be used to tell the bot to move the cursor so that the left cursor box is at the given column (Which can be anything integer 0 to 4) and row (Which can be anything integer 0 to 10) of the 11x5 playing grid. Presumably, the next step is to parse the grid and to have the bot decide what moves to make accordingly.
So, if anyone has any ideas or wants to contribute, I'm all ears. My current code can be seen below:
Language: lua
function chain()
end
function cursor(col, row)
local mode
while mode == nil or mode == 1 do
mode = memory.readbyte(0x7E00B1)
local coal = memory.readbyte(0x7E03A6)
local roal = 15 - memory.readbyte(0x7E03AA)
if coal > col then
press(1, {left=true})
end
if coal < col then
press(1, {right=true})
end
if roal <row> row then
press(1, {down=true})
end
if coal == col and roal == row then
break
end
end
end
function draw()
local grid = parse()
local ascii = ''
for row = 11, 1, -1 do
ascii = ascii .. '|'
for col = 1, 6 do
ascii = ascii .. grid[col][row] .. '|'
end
ascii = ascii .. '\n'
end
gui.text(105, 0, ascii)
end
function parse()
local array = {}
for col = 0, 5 do
local entry = {}
for row = 0, 10 do
local address = 0x7E1860 + (col * 2) - (row * 0x10)
local value = memory.readbyte(address)
if memory.readbyte(address + 1) ~= 0 then
value = 'G'
end
table.insert(entry, value)
end
table.insert(array, entry)
end
return array
end
function press(controller, buttons)
joypad.set(controller, buttons)

emu.frameadvance()
