Ive used the iframe_html_pode and all works fine
except when export to cocoonjs
How can I solve that ?
Develop games in your browser. Powerful, performant & highly capable.
You'd need to write a plugin which supports the CocoonJS Webview Extension. More info here: cocoonjs:extensions:basic:webview - Ludei. Or you could request that Pode implements it into his plugin.
The Clay.io plugin is a great reference for utilising the webview extension.
