Buttons and Changing Screens

Director Class
1

Sorry for the newbie question. Just started with Corona a few days ago with limited programming experience and have already pieced together about half of my basic app.

Question: I have a screen with 2 buttons. Pressing each button should change screens. Is there a way to dynamically pass a variable in the addEventListener so that I can create one function to switch screens.

Not complete code below, just a general idea.

function pressChangeScreen (event)
director:changeScene (variable)

button1:addEventListener (“touch”, pressChangeScreen)
button2:addEventListener (“touch”, pressChangeScreen)

can these event listeners above be passed with a variable so each button can use the same function and go to a different screen.

thanks,

I dont seem to understand why you want the use the same function to change screens?

here’s the way I do it;

  
function button1:tap()   
director:changeScene('whatever','whatever') -- you can put whatever you want here for transitions etc  
end  
  
function button2:tap()  
director:changeScene('whatever', 'whatever')-- same thing here   
end  
  
button1:addEventListener('tap', button1)  
button2:addEventListener('tap', button2)

not sure if thats helpful but thats how I do it in my apps [import]uid: 24641 topic_id: 6706 reply_id: 23729[/import]

Thanks. I was hoping there was a way to have only one function to change scenes and use it multiple times passing the scene name as the variable. It looks like I need to create a function for every button. [import]uid: 38758 topic_id: 6706 reply_id: 23977[/import]

yeah, that’s what I do, not sure if it’s the most efficient but it works every time :stuck_out_tongue: [import]uid: 24641 topic_id: 6706 reply_id: 24030[/import]
