While Unity3D had its flash exporter in beta, I’ve created a bridge to be able to add MochiAds to Unity3D flash games. Unfortunately this bridge didn’t work anymore since Unity released version 3.5.7 and later 4.
I’ve been creating a little plugin for Unity3D Flash to enable some of the features that MochiAds (Advertisements, leader boards, awards, etc) has to offer. Wrote an article about it with instructions on how to use it in a MochiLand article. Check it out:
