Randomize texts

Hey huys,
So I have these texts:

text 1 = display.newText("Text 1", 20, 40, native.systemFont, 20)  
text 2 = display.newText("Text 2", 20, 40, native.systemFont, 20)  
text 3 = display.newText("Text 3", 20, 40, native.systemFont, 20)  
text 4 = display.newText("Text 4", 20, 40, native.systemFont, 20)  
text 5 = display.newText("Text 5", 20, 40, native.systemFont, 20)

I need one of them to be randomly selected to appear each time the scene starts. How do I do that? Can someone help me with the code?

Thanks!

First, put all of your objects into a table like so:

[lua]local table = {
“Text1”,
“Text2”,
“Text3”,
“Text4”,
}[/lua]

Then when you want the scene to start, create new text with the value from one of the random table items inside of it:

[lua]display.newText(table[math.random(1,#table)], 0, 0, native.systemFont, 50)[/lua]

Hope this helps!

Beautifully elegant solution, Jordan! [import]uid: 52491 topic_id: 20369 reply_id: 79658[/import]

It didn’t quite work, but I managed something with a table, thanks!

Another question:
My texts are long. How do I break them into more lines? And then make them centralized?

display.newText() has two more parameters that specify the width and optional height of the box to fit the text into and it will automatically wrap if you use this:

local text1 = display.newText(string, x, y, width, height, font, fontSize)
That should help you out. [import]uid: 19626 topic_id: 20369 reply_id: 80085[/import]

Hm this isn’t working! It worked with width, but when I set height to 0 as it tells me to, nothing happens, and if I set like 500, it just distorts the whole text instead of adding lines.
Is there another way? [import]uid: 95495 topic_id: 20369 reply_id: 80482[/import]
