Background Image Issues

Getting Started Newbie Questions
#1

I am a new user of Corona and trying to learn code. I have just started to develop a game and I want it in the Landscape view always. I have gotten my opening screen up and in the landscape view but my image is slightly too big and I want to scale it down. My files look like this below.

Also the build.settings file is that a file you create in text editor also. I wanted to look in some of the build.settings files of the example apps they have posted on the site but I can’t open them. What kind of file is it and how do you create one?

Thanks a million for your help!

Michelle

config.lua (file 1)

application =
(
content =
(
width = 320,
height = 480,
scale = “letterbox”
)
)

titlescreen.lua (file 2)
local background = display.newImage (“title.jpg”, 0, 0, true)
background.x = display.contentWidth / 2
background.x = display.contentHeight / 2
localGroup:insert(background)

return localGroup

Heya,

You can open build.settings in the same text editor that you use for Lua, just drag and drop. (If you’re looking for a text editor, Eddie is basic and clean.)

For your background image; I’d resize it manually myself in Photoshop (or the like) - but you can also use xScale and yScale if you really don’t want to.

Hope that helps!

Peach,

Thank you so much for the reply. In regards to the build.settings file, all of them are grayed out and I can’t select them. I have tried several times. This is even on the sample examples on the website. I am currently using TextWrangler.

In regards to photoshop, I have not used that but I do have it. I thought you could only save files as a photoshop extention. Can you save as a .png or .jpg in that software. Thanks a million.

Peach,

I got the background image fixed and centered the way I wanted it. I have one other question and I have seen several ways to do it but it does not seem to want to work for me. I want a red block to drop when my titlescreen opens. I tried to use the simple code from the program in 8 minutes and it doesn’t seem to work. This is what I have and if it works I should be able to throw the block around also. Can you see what’s wrong in my code?
[lua]module(…, package.seeall)

function new()
local localGroup = display.newGroup()

local physics = require(“physics”)
physics.start()
physics.setGravity(0, 4.9)

system.activate( “multitouch” )

– physics.setDrawmode(“hybrid”)

local background = display.newImage (“title2.png”)
background.x = display.contentWidth / 2
background.y = display.contentHeight / 2
localGroup:insert(background)
–> This sets the background

local redblock = display.newImage(“redblock.png”)
redblock.x = display.contentWidth/2
physics.addBody( redblock, (bounce = 0.4, friction = .2) )

– Define our touch event listerner.
function doImpulse(event)
redblock:applyLinearImpulse( 0, -0.2, event.x, event.y )

end

–Add the listener to our redblock
redblock:addEventListener(“touch”, doImpulse)[/lua]

*Edited by Peach Pellen: Please put code you post in Lua tags. < lua > and < / lua > without the spaces. Much easier to read :wink:

First up, build.settings - download Eddie. http://www.macupdate.com/app/mac/19658/eddie/

I think these should open in any editor but I don’t know for sure; that’s not my area of expertise :wink: But I know Eddie opens them as I use it myself. (It’s free, nothing fancy, just a basic editor.)

For Photoshop, yes, you can save as a bunch of image formats including GIF, JPG and PNG. Hit CMD+SHIFT+S to do a “Save As”, or choose it in the menu manually.

For the block - is this just a visual effect you’re trying to do? If so, do you know how to do a transition? It would be far simpler :slight_smile: [import]uid: 52491 topic_id: 12018 reply_id: 44008[/import]

Got it fixed!!! [import]uid: 72372 topic_id: 12018 reply_id: 44032[/import]

Well done :slight_smile: [import]uid: 52491 topic_id: 12018 reply_id: 44179[/import]

Peach,

How do I post my code on here with Lua Tags. I have been asked to do that but I’m just copying from my file and pasting it now. I assume they want it with the color coding when they say with Lua Tags.

Caleb explained this really well in your other thread - just put < lua > before your code and < / lua > after it. (without the spaces) [import]uid: 52491 topic_id: 12018 reply_id: 44378[/import]
