Hit button once

Its probably not the best implementation but it saves time and code so... here it is.

Here is an example of how to use it. Make sure oldpad is at the bottom of your index.lua or whatever you are running. Also make sure pad is at the top.

--Init
oldpad = Controls.read()
 
while true do
pad = Controls.read()
 
..
 
if cp(start) then break end
 
..
 
oldpad = pad
end

Heres the function so you can push a button once. A good use of this would be for menus and stuff like that.

triangle = 1 square = 2 cross = 3 circle = 4 up = 5 down = 6
left = 7 right = 8 r = 9 l = 10
 
function cp(cpad)
 if cpad == triangle then
	if pad:triangle() and oldpad:triangle() ~= pad:triangle() then return true end
 elseif cpad == square then
	if pad:square() and oldpad:square() ~= pad:square() then return true end
 elseif cpad == cross then
	if pad:cross() and oldpad:cross() ~= pad:cross() then return true end
 elseif cpad == circle then
	if pad:circle() and oldpad:circle() ~= pad:circle() then return true end
 elseif cpad == up then
	if pad:up() and oldpad:up() ~= pad:up() then return true end
 elseif cpad == down then
	if pad:down() and oldpad:down() ~= pad:down() then return true end
 elseif cpad == left then
	if pad:left() and oldpad:left() ~= pad:left() then return true end
 elseif cpad == right then
	if pad:right() and oldpad:right() ~= pad:right() then return true end
 elseif cpad == r then
	if pad:r() and oldpad:r() ~= pad:r() then return true end
 elseif cpad == l then
	if pad:l() and oldpad:l() ~= pad:l() then return true end
 else 
	return false 
 end
 
end
