NeonShaped module : Module 'plugin_utf8' not found

Corona Marketplace Corona Community Plugins
#1

I’m using the Neon shapes plugin by René Aye

I have one line of code

local Neon = require( "devilsquid.neonshapes.neon" )

which generates an error

Corona Simulator Runtime error Module 'plugin\_utf8' not found: no field package.preload['plugin\_utf8'] no file '/Users/d/Library/Application Support/Corona/Simulator/Plugins/plugin\_utf8.lua' no file '/Users/d/Sites/ramen/app/sixBeforeSix/plugin\_utf8.lua' no file '/Applications/Corona-3268/Corona Simulator.app/Contents/Resources/plugin\_utf8.lua' no file '/Users/d/Library/Application Support/Corona/Simulator/Plugins/plugin\_utf8.dylib' no file './plugin\_utf8.dylib' no file '/Applications/Corona-3268/Corona Simulator.app/Contents/Resources/plugin\_utf8.dylib' File: module 'plugin\_utf8' not found stack traceback: [C]: in function 'require' ?: in function 'require' devilsquid/util/fontmanager.lua:16: in main chunk [C]: in function 'require' ?: in function 'require' devilsquid/neonshapes/neon.lua:16: in main chunk [C]: in function 'require' ?: in function 'require' main.lua:14: in main chunk

I’m following the instructions here https://devilsquid.com/create-flickering-neon-effects-corona-sdk/

I have the  devilsquid folder in my root of your Corona SDK project.

Any ideas? Thanks.

I’m pretty sure you need to be a member of his site, and download the plugin, then put it in your project.

Installation

To Download the NeonShapes you need to be part of our free Basic membership or of our paid Premium plan. If you are already a member, you can dowload the latest version of this module in your member download section.

You can’t just add that line to a project and have it work.

Hi there,

thanks for the reply.

I have indeed downloaded the module and placed in the  the devilsquid folder in my root of my Corona SDK project.

That’s not all there is to it.  You need the util folder too.

Testing, and will type steps in a moment.

thanks for your assistance.

I have the following in the devilsquid folder

Looks like his code depends on the utf-8 plugin: https://docs.coronalabs.com/plugin/utf8/index.html

Make sure to put this in build.settings file:

   plugins =    {       ["plugin.utf8"] = { publisherId = "com.coronalabs" },    },   

For example, my full build.settings file for running his test code looks like this:

-- ============================================================= -- Minimalistic 'starter' build.settings -- ============================================================= -- https://docs.coronalabs.com/guide/distribution/buildSettings/index.html -- https://docs.coronalabs.com/guide/tvos/index.html -- https://docs.coronalabs.com/guide/distribution/win32Build/index.html -- https://docs.coronalabs.com/guide/distribution/osxBuild/index.html -- ============================================================= local orientation = 'portrait' -- portrait, landscapeRight, ... settings = { ------------------------------------------------------------------------------- -- Orientation Settings ------------------------------------------------------------------------------- orientation = { default = orientation, supported = { orientation }, }, plugins = { ["plugin.utf8"] = { publisherId = "com.coronalabs" }, }, --[[build = { neverStripDebugInfo = true, }, --]] }

I tried requiring example0.lua from main.lua to essentially run the scripts in it.

I got some missing image warnings.

So, I copied the img folder (from the downloaded zip) into ‘devilsquid/neonshapes/’

Now it runs fine.

sent you a pm with my project attached.

scroll to top of screen here and you should see a little mail icon with a notification bubble.  Click it.

Hi again,

Many thanks for going above and beyond the call of duty. Using your examples I was able to get it working.

Glad to hear it.  Welcome to the community.

It’s a bit early and not related to this question, but for future reference I have many coded answers to forums questions here:
