问题 What is the best way to remove all spawned coins when the game is over? Here is the code that spawns the coins: screenGroup = self.view coin = {} coinspawn = function() i = display.newSprite( imageSheet1, sequenceData1 ) i.x = display.contentWidth i.y = math.random(0, display.contentHeight-50) i:play() i.collided = true i.name = "coin" physics.addBody(i, "dynamic", {density=.1, bounce=0.1, friction=.2, shape= shape2 ,filter=playerCollisionFilter } ) --player.gravityScale = 0.5 coinIntro =

问题 I'm making a main menu scene in corona, however I've come across an error and its driving me crazy. The compiler makes it confusing for me to understand what it is but I can point out 2 problems from it: attempt to call global "startButtonListeners" [C] in function "startButtonListeners" Here is the section of code: function scene:enterScene(event) local group = self.view startButtonListeners('add') function startButtonListeners(action) if(action == 'add') then aboutBtn:addEventListener('tap'

问题 I have 2 server file work with corona simulator. One is work but another isn't. Not sure what is the different between these 2 file. Below is my server code. Non-working: class Chat(Protocol): def connectionMade(self): self.factory.clients.append(self) def connectionLost(self, reason): self.factory.clients.remove(self) def dataReceived(self,data): for c in self.factory.clients: c.message(data) print data def message(self, data): self.transport.write(data) factory = Factory() factory.clients =

问题 I have an area where the enemy needs to be spawned to look good (they are behind a fence) and I don't want the enemies to spawn over each other so I was wondering if there is any good way to do this? http://sv.tinypic.com/r/2zowwu1/8 I created a function that check if the next box (the next enemy) fits in all possible positions (pixel by pixel) but this is to slow as it is a mobile application and the enemies can be spawned rather fast sometimes. Sure there must be a nice formula that can

问题 I have 2 object Object1 and Object2 When I use transition.to(Object1,{time=1000,x=Object2.x,y = Object2.y}) Object1 will be above Object2. If I want Object2 to be above Object1, how can I do? Thanks for all answers! 回答1: You can use object:toFront to move Object2 to front. Something like this: Object2:toFront() Note: this not only moves Object2 in front of Object1 but in front of all other siblings. If you want more control about displaying you need to built it yourself :) 来源： https:/

问题 I'm trying trying to have users name fade in one letter at a time vertically. Example: Adam "A" would appear after 1 second , "d" would appear after 3 seconds under the displayed A, "a" would appear after 5 seconds under the displayed d, "m" would appear after 7 seconds under the displayed a. The visuals would have a sort of domino effect.When they appear they would stay displayed on screen. When if I comment out userNameField:removeSelf () then the code works fine. I get the effect I want,

问题 this is how i call a function from menu.lua at main.lua local menu = require("menu") menu.drawMenu() but how i gonna call a function from main.lua at menu.lua ? is it possible ? or set a listener or something like that 回答1: If you are simply looking to provide actions for the menu, would it not be better to use a set of call back functions (as used when building GUI elements) to be triggered when menu items are clicked?

问题 By default AVD runs ARMv6, is there any way to make it emulate an ARMv7 device? 回答1: There is the ability to download an "ARM EABI v7a System Image" via the 'SDK Manager tool' (this is in the 4.2 API product tree). Then you will need to create an emulator, that uses this system image. If the image you are looking for doesn't exist (you aren't seeing it in the list of downloadable options in the SDK Manager) it probably isn't possible right now. Bottom line, you will need the ARMv7 system
