hey youaresam, i dunt understand the math.ceil function much.. so howo can you do this? if analog stik moves LEFT, the speed = speed-1 . if analog stik moves RIGHT, then speed = speed+1. thx!

---

math.ceil(number) returns the valuse put in, and if there is any decimal value, it goes up one. like:
5 would be 5
5.1 would be 6
5.7 would be 6
8 would be 8
8.4 would be 9

I just came up with a formula that would return 1 or -1 based on if the number was positive or negative. Yeah, its a bit confusing, but it should work.

Ok... http://forums.qj.net/images/smilies/neutral.gif
Here, this will display "Hello", then if you press cross, it will say "Goodbye" for 1 second.

green = Color.new(0,255,0)
while true do
screen:clear()
screen:print(10,10,"Hello ",green)
pad = Controls.read()
if pad:cross() then
screen:clear()
screen:print(10,10,"Goodb ye",green)
screen.flip()
screen.waitVblankStart(60 )
end
if pad:start() then break end
screen.waitVblankStart()
screen.flip()
end


And, yes, the tutorial Shine wrote has everything you need. Back when I learned, Shines tutorials were half way done! (And of course, there were NO other LuaPlayer tutorials what-so-ever)

im sorry. :Cry: :Cry:

my code:(so far)

Code:

---


speed = 0

pad = Controls.read()
dx = pad:analogX()
dy = pad:analogY()

        if math.abs(dx) > 32 then
                cursorx = cursorx + dx / 64
        end
       
        if math.abs(dy) > 32 then
                cursory = cursory + dy / 64
        end
end

---

i want it so that when the analog stik goes LEFT, the speed will decrease, and when it goes RIGHT, the speed will increase.

thx for ur help(yoursam), and sry for pissing u off(sigg)

I already showed you my formula.

height = height + math.ceil(1/dx)

Modify it to your needs. Basically, if dx is positive, it adds 1 to height. if its negative, it subtracts 1 from height.

OR if you want to add or subtract more, just put a number at the end. For example, to add or subtract 4, do this:

height = height + math.ceil(1/dx)4

im new to lua but i do know javascript and you forgot to declare 2 of your variables cursorx and cursory
