Corona SDK - Feature Requests/Feedback

Welcome to the Corona SDK feature request/feedback tool.

Tell us what features you would like to see in Corona by entering new ones and/or voting on existing entries.

PLEASE NOTE:

  • You only have 15 votes. Use them wisely! You only regain votes if we delete or close an item.
  • Write short descriptions/comments to give us context on what you need and mean.
  • This tool is not for asking questions or long discussions. Use our forum instead.

What features should we add to Corona SDK?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Draw smooth curves efficiently

    It is impossible to make a paint app just like drawing carl, that user can draw smooth curves efficiently,

    • add meshes support for spine

      From the Spine official blog:


      "On the runtime side of things, almost all of the runtimes are up to date with the latest editor features. Corona is yet unable to render meshes, but the Corona guys are working on that. LÖVE can render meshes, but hasn't been updated to do so yet. All the other runtimes are up to date and work great with IK, meshes, weights, bone flipping, etc."


      Hopefully Corona Labs will sort this out as this isn't the best promotion for Corona.

      • Antialiasing for drawn shapes (rounded rects, circles, ...)

        Please re-introduce antialiasing for drawn shapes (rounded rects, circles, ...) in corona. Right now those shapes cannot be used because they look horrible without antialiasing.

        • isBounceEnabled for webView

          scrollView supports isBounceEnabled to enable/disable the bouncing effect when you reach the end of the scroll.

          Corona API should support the same feature for webView.
          It's really needed since some webapps break by scrolling past the end of "fixed" objects in the webview.

          iOS 5.x+ supports it already with this simple command:
          webView.scrollView.bounces = NO;

          • Allow specification of email attachment's Content-id

            In order to properly include an image inline of email message, we require content-id to be set on the attachment.
            I think this would be an easy thing to implement and would allow sending proper emails.

            • system.getFrameID() or system.getTimerAtStartOfFrame()

              It would occasionally be handy to know which frame it is.

              For instance, we might want ask for something several times, but only need the same results (memoization). For that matter, we might not need them right away, or perhaps not at all (lazy evaluation).

              When the logic also needs to be ready at a moment's notice, it can be difficult to have all the details in order.

              If this situation arises on a per-frame basis, however, it can be built on top of a frame ID.

              In a given piece of code, we might have some "last known ID"…

              • Allow widget theme imags to be excluded from build

                Thread reference: https://forums.coronalabs.com/topic/57369-extraneous-gunk-in-apk/

                Suggestion: For a project that does not use the widget library at all, allow it to specify (presumably in build.settings) that the widget theme images should be excluded from the build, thus saving approx 900K file size. For example:

                -- somewhere in build.settings
                -- defaulting to false if not present to preserve current functionality
                excludeWidgetThemes = true,
                -- (or reversing the logic to "includeWidgetThemes = false," defaulting to true - whichever suits)

                Depending on the complexity of implementing, (for example, if requiring widgets become a plugin to fully implement), it would acceptable if this flag merely caused…

                • Extend facebook support to handle clients already logged in

                  The current Facebook API requires facebook.login() be called when the app starts to register a handler which forces the app to switch away to facebook then back. In the case where you are already logged in from a previous run of the app, this should not be necessary. Perhaps add a parameter to login which was the access token retrieved from a previous login to prevent a switch

                  • Support for Touch ID API

                    Apple has a Touch ID API for authenticating users biometrically. I would love for Corona to support this API natively.

                    Many thanks!

                      • Fix "elseif" bug indentation issue in CoronaEditor when using "Edit->Line->Reindent" to reformat existing code.

                        Fix "elseif" bug indentation issue in CoronaEditor when using "Edit->Line->Reindent" to reformat existing code. Some code doesn't indent to the proper spacing when it comes across an "elseif" statement and causes all code to continue to indent out ad-infinitum.

                              • Abillity to have a delay after the transition.

                                It will have at list two ways it would help:
                                1. The onComplete could be delayed.
                                2. We will be able to put two tranitions on the same body which will iterate istead of making a whole function.

                                Example of an implemention:

                                transition.to ( Ball, {delay=1000, time = 1000, delta = true, x = 100, iterations = 0)
                                transition.to ( Ball, {time = 1000, afterdelay=1000, delta = true, x = -100, iterations = 0)

                                • Display object instancing, part 2: adding data

                                  The following extends, and assumes familiarity with, the "Display Object Instancing" proposal.

                                  I've used something similar in the past, with another engine, and found it to complement instancing quite well.

                                  SHARED DATA

                                  OpenGLES promises at least 128 vertex uniform vectors. Corona snags a few of those, and your own vertex shader might grab some more, but there will probably be many remaining. Since we have an index handy, and we know we'll be sticking with the same shader for a while, it's a shame to let them all just sit there! :)

                                  In the kernel, we could write

                                  kernel.sharedVertexFormat =…

                                  • Display object instancing

                                    This feature request is a simpler and more powerful successor to my earlier "copycat object" proposal. Custom shaders and snapshots have become available since then; in some ways, the previous idea was trying to dance around their absence.

                                    BASIC IDEA

                                    When defining a shader effect, one could add the line

                                    kernel.isInstanced = true

                                    and then, on the Lua side, write

                                    -- object gets drawn with the effect, 20 times; default is 1
                                    object.fill.effect.instances = 20

                                    On its own, this doesn't give us much. With normal blending and alphas, we would never even see 19 of the 20 instances, which all…

                                    • localization for push notification in Android

                                      iOS can do the localization for push notification by placing .lproj folder in root and "Localizable.strings" in that folder. However, Android cannot do this trick. It will be good if Android can get the localized push notification like the way iOS do

                                        • [PLUGIN] Image file (jpg/png) resizer with changing of image quality support

                                          It would be great to have something that could take an image file and resize (maybe crop it too) and change its compression level.
