From the Forum – Issue #177

Welcome to this week’s From the Forum. In this post, we highlight a few Corona Community Forums posts that cover important topics.

Physics and groups

Groups are a wonderful way to organize your display objects but sometimes this can create issues for developers using physics. @roaminggamer and @horacebury contributed to a thread that explains the problem and offered up some solutions.

Loading large scenes

Doing tasks in Corona can take time. When you do many tasks in a row, your user interface will block. This can make loading large scenes appear as if your app has frozen. A standard tactic would be to show a progress bar. However, Lua is a single-threaded language that can make it difficult to avoid blocking and allow your progress bar to update. In this thread, several Corona developers jumped in and offered suggestions on how to manage loading a large number of assets.

Making an accordion widget

There are many different ways to present data to users. A popular web technique is an accordion style display where you click on an item and it expands to show more information. Building this in Corona can be a bit tricky since you need to know the height of other objects to move them around to open space for the added info. In this thread, our wonderful community of developers joined to solve the problem.
