Concise game implementations

[undef]

Hey,

let's share very short game implementations.

I wrote this pure Lua, terminal based, two player RPS game today:

Code: Select all

choice, winning = {}, { r = 's', p = 'r', s = 'p' }
for n=1, 2 do
	print( ("Player %d:\nType 'r' for rock, 'p' for paper, or 's' for scissors and press return."):format( n ) )
	while not choice[n] do  choice[n] = io.read():match"^[rps]"  end
end

print( choice[1]==choice[2] and "Draw!" or ("Player %d wins!"):format( winning[choice[1]]==choice[2] and 1 or 2 ) )

Code: Select all

choice, winning = {}, { r = 's', p = 'r', s = 'p' }
for n=1, 2 do
	os.execute("cls") 
	os.execute("clear")
	print( ("Player %d:\nType 'r' for rock, 'p' for paper, or 's' for scissors and press return."):format( n ) )
	while not choice[n] do  choice[n] = io.read():match"^[rps]"  end
end

print( choice[1]==choice[2] and "Draw!" or ("Player %d wins!"):format( winning[choice[1]]==choice[2] and 1 or 2 ) )

I added something to clear the terminal, so the second player can't read the first choice

Ooops, the danger of playtesting alone^^

Graphical snake in 73 lines of code. There are magic numbers in there, but it should be easily understandable.

Controls:

• arrow keys for moving
• Esc or q to quit

There are no borders and the game restarts itself two seconds after losing it.

My trimmed down version is just 51 lines of code long.

How about pong in less than 100 lines of code?

thanks for the pong code!

A few years ago I ported HAMURABI.BAS to lua, it's not "concise" but I figure it's worth a mention: https://gist.github.com/inmatarian/5121902
