Say your text object is called livesDisplay, you would just set the .text property of it:
[lua]–Change the number of lives
lives = lives -1
livesDisplay.text = lives[/lua] [import]uid: 8782 topic_id: 6600 reply_id: 23067[/import]

I’m really not getting this. I have bombs in my game. My text object is called bombCount and by default it displays the number “3.” When the object bombButton is tapped I want the bombCount to decrease by one. At the moment I have this:

function bombButton:tap( event )  
 audio.play( bombSound )  
 bombButton.alpha = .5  
 function returnColor (event)  
 bombButton.alpha = 1  
 end  
 timer.performWithDelay ( 250, returnColor, 1)  
end  
bombButton:addEventListener( "tap", bombButton)

From what I read here I think I need to have something like “bombCount = bombCount -1” in there somewhere but I don’t know where to put it or how to make it work. [import]uid: 35706 topic_id: 6600 reply_id: 25063[/import]

Just put bombCount = bombCount - 1 right underneath where you set the alpha property. You could place it several places, but that’s as good as any.

Since Lua is a “typeless” language you can set the text property as “3” and still perform subtraction on it – and then display it as text again.

Awesome, thanks! It wasn’t working for me at first, but after some trial & error I realized I could just say “bombs = 3” and then have that feed into the bombCount. [import]uid: 35706 topic_id: 6600 reply_id: 25365[/import]
