  1. 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.

        • corona simulator

          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...

          • App orientation based on device type

            Ability to set app orientation based on device type. For example: phone will be portrait, tablet will be landscape.

            It would be the best to use full orientation settings for each device type.

            This feature is essential for mobile app development where business apps most often need to be in different orientations for phone and tablet.

            • Support for image sheets in composite.fill.effect

              Hey guys,
              I've found this amazing tool here called "Dynamic Shader".
              With this you can bring easily nice light effects to your game.

              There's just one big thing, the objects that you can apply the light on can't be sprites from an image sheet. It must be a single image.

              The developer of the tool said this here:
              <quote>
              The graphics 2.0 composite.fill.effect parameters require a "type" (like "image") and a location of the image files. Since image sheets are one big file, I have to break up the sprites and normal maps on those sheets and re-save them as…

                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

                      • Update firebase sdk and gps to 11 on android

                        In order to take advantage of the new firebase features like phone login and performance logging on android, firebase needs to be updated to 11.

                        Google play services would also need to be updated 11 as well.

                        • 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

                                Create functionality that allows us to have a context menu on a application's toolbar/taskbar icon to include a context-sensitive menu created in app. This would be great for apps that are frequently minimized.

                                • Nintendo Switch Support

                                  Now that it has been confirmed that the Nintendo Switch will allow for games that only support the touchscreen - http://www.eurogamer.net/articles/2017-02-27-nintendo-switch-has-its-first-touchscreen-only-game - it seems like a good time to bring up the question of Corona support.

                                  Obviously supporting new platforms is a massive undertaking, however, it would be great to know if this is even considered a possibility?

                                  With the support for touchscreen-only games and the fact that Unity will be supporting the Switch, I can imagine a lot of previously mobile-only games finding a new home on the console.

                                    • 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})

                                      • Run Scripts in app project

                                        In order to support crash logging on sdks like Firebase and Crashlytics, adding Run Scripts to app is required.

                                        maybe something like this

                                        iphone =
                                        {
                                        runScripts = {
                                        [["${PROJECT_DIR}/fabricRun" secretCode]],
                                        },

                                        },

                                        • [Plugin] WiFi Direct

                                          A request to add the WiFi direct methods in Corona. Plugins like Autolan and Zeroconf aren't feasible due to the fact that what I'm aiming for is the ability for a wireless proximity based connection between devices and bluetooth is not really an option.
