Center Text

[Virtue]

How can you center text in Lua?

Lets say I have this:

screenrint(x, 240, message)
if msg = 1 then
message = "HELLO!"
end


if msg = 2 then
message = "HELLO! I AM SO FRIGGEN COOL HAHA"
end


And it's in a loop, where message variable can change at any moment, how can I get it to print the message in the middle, so its always even?

Thanks.

Well, I think there is a function to get the length of a string. So if you could find the size of each character, multiply them by the length of the string, then divide that number by two, you would get half the length of the string. Subtract that from the original position and it will center it on the original position... I think... I got 1 hour of sleep last night... >_>

Edit: I think I'm gonna code this, it sounds like fun. Expect another reply in a while. =P

Ahh dude, thanks sooo much. I mean, I had teh same idea if their wasn't a function to do this automatically, but if you code the example it will be easier for me to implement it

I know in most langauges it would be like this to get the lenght of a string:

lenofmsg = Len(message)

Not sure about Lua

Also lancer, do you have aim or msn?

System.usbDiskModeActivate()

red = Color.new(255, 0, 0)

function centerText(where, y, text, color)
	where:print((screen:width()/2)-((string.len(text)/2)*8), y, text, color)
end

centerText(screen, 240, "HELLO!!!", red)
screen:flip()

repeat
	pad = Controls.read()
until pad:cross()

I think that would work.

No errors, but doesn't work... hmm?

Aw... Beat me to it. =[ I'll post mine anyway.

function centertext(x, str)
	return x - ((string.len(str) * 8) / 2)
end

The function in use:

screen:print(centertext(100, "ZOMGHAX"), 200, "ZOMGHAX", white)

Of course, 100 could be changed to 480/2 and 200 could be changed to 272/2 to get the center of the screen.

Edit: You can get ahold of me on AIM, my username is LancerY. Also, the reason his code doesnt work is because his print and screen:flip aren't in a loop.
