  1. Composer stops previous scene's runtime events and event listeners

    It would be great if the composer could handle stopping all runtime events and event listeners of the previous scene when goToScene is called (or when a new scene is loaded).

    • Basic 3D

      Basic 3d transformations For example if you had a game board on one side of a cube and user could then swipe the cube to rotate to another side which has more paths for the player character to follow. Doesn't have to be true 3D rendering if that's out of scope, just some kind of way to do transformations like described here.

      • Ability to place native object below Corona view [Corona native]

        Ability to create plugins which allow placing native objects under corona view. This can be useful for video player where we could build UI with corona instead of native elements.

        • A manual "simulateTouch( event )"

          I would like the ability to manually fire a touch event that gets treated like a regular touch event.

          Essentially how the mouse is treated on desktop builds where display objects get told about it as if they were actually touched.

          I'm hoping that as this ability must already be built into Corona it might be relatively easy to allow us to hook into it?

          Please see this thread for more info - https://forums.coronalabs.com/topic/71198-manually-fire-a-touch-event

          • Disable Native WebView Zoom buttons

            There's no way to disable Zoom Buttons of the WebView in Corona and this is quite frustrating because they continously appear on screen using Android.

            However, as posted on Stack Overflow, there's a way to do it in Java overriding some methods. Explanation can found here: https://stackoverflow.com/a/11901948

            Best solution would be to have a boolean property like "zoomButtonsEnabled" to control this.

            I don't know if on iOS there's the same problem.

            Thanks in advance!

            • Z-index

              Z-Index for easily being in control of what objects should be in the front and in the back, should be added as a property for all objects e.g bkg.z-index=1

              • Radial Gravity with Particle Systems

                (I'm not sure what category this should be under, so feel free to mark it under whatever is related to LiquidFun/Physics.)

                LiquidFun's API allows for radial gravity via the ReportParticle callback of the QueryAABB and QueryShapeAABB methods. Note LiquidFun's methods ParticleApplyForce and ParticleApplyLinearImpulse.

                Core features being requested:
                - Expose LiquidFun's ParticleApplyForce and ParticleApplyLinearImpulse methods on ParticleSystem objects.
                - Add an index property to the "hits" table returned from ParticleSystem:queryRegion()
                - Expose LiquidFun's QueryShapeAABB method so we can query circular regions. This allows for more natural/accurate radial gravity behavior.

                Alternatively, feel free to encapsulate these ideas into your own preferred methods.…

                • MQTT and IOT integration

                  Would be nice to have updated plugins and docs. on mqtt handelig, i.e. towards iot.eclipse.org and maybe other servers. I can make some tutorials on configuring NodeMCU and Wemos R1. The goal would be to make Corona apps that can handle SmartHouse integration

                  • Easier way to POST simple text field forms

                    Easier way to POST simple strings that then look like simple form Post fields on the server side (simpler forms and processing like with html forms). Easier way to POST simple string that look like form fields on the server side (simpler forms and processing like with html forms). Would help tremendously with creating accounts and also all business apps

                    • Support modification of package path

                      It would be super helpful if Corona SDK could support modifications to the package path (http://lua-users.org/wiki/PackagePath).

                      This would - among other things - support the easy setup of Lua-only Luarocks installed in a local tree:
                      http://leafo.net/guides/customizing-the-luarocks-tree.html

                      This would make code sharing and working with external libraries/dependencies much easier, but for it to work we need to be able to modify the package path:

                      package.path = 'lua_modules/share/lua/5.1/?.lua;lua_modules/share/lua/' .. version .. '/?/init.lua;' .. package.path

                        • emboss=true button text should fade properly

                          Currently if you set emboss=true when creating a button object, and then fade that button object using alpha values, the embossed text doesn't fade properly.

                          Simple test case (requires some kind of button image file):

                          local widget = require "widget"
                          local composer = require( "composer" )
                          local scene = composer.newScene()

                          local aboutBN = widget.newButton{
                          label="Embossed Button Text",
                          labelColor = { default={ 0, 0, 0 }, over={ 0, 0, 0, 0.5 } },
                          defaultFile="ButtonBig.png",
                          overFile="ButtonBig_down.png",
                          width=154, height=40,
                          x = display.contentCenterX,
                          y = display.contentCenterY + 120,
                          emboss=true,
                          alpha = 0
                          }
                          aboutBN.alpha=0

                          transition.to(aboutBN, {alpha=1, time=5000, delay=500})
                          transition.to(aboutBN, {alpha=0, time=5000, delay=5500})

                              • A server to receive all errors

                                Purpose a plugin who send automatically all errors from all device to a server. The server classify the data and show it to the developer.
                                - All developers need this plugin
                                - The reputation of corona will increase because corona app will have less bug

                                If someone is interest to develop it and need more informations, I can provide them because I use it every day to improve my app !

                                In the app:
                                local function networkListener( event )

                                • Update AdColony Plugin to 3.3.0

                                  AdColony mention:
                                  "Several bug fixes, memory usage optimizations, and stability improvements"
                                  in 3.3.0 .. this could help with some crashes we face.
                                  No need for new api or any modification. just rebuild plugin with newer sdk

                                      Add a setting to clear the output screen of the simulator at the start of each application relaunch. This is a companion to the relaunch on program change, which is handy but leaves the output screen with combined output, not just the latest execution. To find the top, you have to slowly scan through the output looking for the latest top...

                                        • contentBounds should be able to be accessed as non-rounded value

                                          Have these just as integers prevents us from using it for positioning. Since an object with 'x' position of 0 has the same xMin as an object with 'x' position of 0.4.

                                          I understand this can't be changed all of a sudden because it could break existing implementations, but wouldn't it be an idea to add an additional one? (eg. preciseContentBounds or display.setDefault("contentBoundMode", "float"))

                                          This will make it viable to use for positioning, as described in this post.
