### Re: get what angle an object is moving at ?

Generally you would want to have discrete steps with some time in between because of minor inaccuracies and the really small change in position. The solution is trigonometry! The formula is: angle = math.atan2(dx, dy) Where dx and dy are the difference between pointA and pointB. dx = math.abs(x1 - ...

### Re: checking if a value is not on table ?

If you want to know if a value is inside the table, you might as well return the index. You should probably check if the search value is non-nil to prevent bugs: --- Finds the first occurrence in a list -- @param t Table -- @param s Search value -- @param o Starting index (optional) -- @return Nume...

### checking if a value is not on table ?

for example:

Code: Select all

love.load()
a = 9
table = {}
for i=0, 10, 1 do
table.insert(table, i)
end
end

love.draw()
for i,v in pairs(table) do
if v ~= a then
--print something
end
end
end

so what i want to do here is to print something out only once if the value is not on table, how do i do it ?
