corona

问题 I'm using CORONA SDK. I have a set of pages and I would like to slide between them using swipe left -right. The page contains a set of controls (mostly text) What is the best way to do this slide/swipe in Corona? 回答1: Using touch events. When the phase of event is "began" (The user just touched the screen), allow the three pages to move (the actual, the forwards and the backwards). if event.phase == "began" then page1.canMove = true page2.canMove = true page3.canMove = true initial = {}

问题 I have a joystick graphic placed in the corner of the screen in my Corona game. When the user touches the joystick and drags it from side-to-side, it moves the character. However, if the user drags from the middle of the joystick all the way off to the side , then removes his/her finger, the character keeps on moving. I'd like the character to stop on touch-up, even if the touch up is no longer on the joystick graphic. The joystick image subscribes to the "touch" listener with control

问题 I am new to Corona and I have a set of 10 question and the input is in the range from 0-8. I have code it such that my numeric textbox will loop for i times (i = number of question in array). My question is how do I insert these value that is being keyed in into the database that i have created? Do i need to assign these individual question with a variable? local madrs = display.newGroup() local function textListener( event ) if ( event.phase == "began" ) then elseif ( event.phase == "ended"

问题 I'm learning Lua for corona sdk and I have these local type1 = {nil, "(", nil, "x" ,nil , ")" ; n=6} local type2 = {"(",nil, "x",nil, ")",nil ; n=6} print(#type1) --prints 6 print(#type2) --prints 3 why the second one is not 6 too?? 回答1: The # operator doesn't work on every table, it works only on a sequence, that is, the set of its positive numeric keys is equal to {1..n} for some integer n . In that case, n is its length. For instance, local t = {"hello", 42, true} is a sequence. But both

问题 I'm using Corona SDK, Sublime Text 3, and Lua. My goal in this particular program is to make a visual novel app that changes when the player clicks on the text displayed at the bottom of the screen to progress to the next text entry, therefore continuing the story. I set up a bunch of code for logo, title screen, and other things, that works perfectly. What I'm currently trying to do within the visual novel scene is to use a table to draw the text from by change the .TEXT property to select a

问题 How can I check cpu usage of my application with Corona SDK? the only thing i found on google is how to check memory usage collectgarbage() print( "MemUsage: " .. collectgarbage("count") ) local textMem = system.getInfo( "textureMemoryUsed" ) / 1000000 print( "TexMem: " .. textMem ) 回答1: Sorry, there is currently no way to check the cpu usage of your application in Corona SDK. 来源： https://stackoverflow.com/questions/17632091/how-to-check-cpu-usage-of-my-application

问题 I like that corona compiles to multiple environments, but I want to know what size sprites, and images do I need. I mean I don't have time to create separate images for every conceivable device size. I know corona supports some auto scaling of images. So for example if I have a 64x64 sprite is that all I need? or do I need new image sizes for every scenario? I am looking for 80% coverage not perfect for every device. 回答1: I'm doing it in a different way. I think this may help you. As my
