Back in 2009 I wrote the Detonator Explosion System and it's been used in a lot of Unity projects. In fact if you look at the URL it was apparently the very first asset that Unity submitted to the Asset Store. However that was a really long time ago, especially in Unity years! Well recently I have been able to dedicate some time to maintaining it and this thread will serve as my contact point with the community. Please post any bug reports and feature requests in this thread. Thanks! EDIT 9/22/2014 - Detonator 1.23 for Unity 4.x is live in the Asset Store Asset Store Link: https://www.assetstore.unity3d.com/en/#!/content/1 NOTE: The new minimum version is Unity 4.0.0, not 4.5.3. This should help some people out.
