UPDATE 4/11/16: For those wondering why I never released this mod it is because I had heard through the grapevine that pistons will be in the next update (which they are). Also it was during testing season and I was really really really busy :P

Terrain deformation didn't work out unfortunately but I have a new mod that will be released soon that adds pistons in the game. These are initially the size of an rcs thruster and extends out from there. The amount of extension can be changed in the block setting menu. The 3d model is very basic I'm still working on it. You can mount all sorts of things on this including missiles (extremely useful for missile bays), bombs, guns, anything. Screenshots coming soon followed by release. If you want to beta test please reply with your platform (android/PC) and device (only android). I'll pick some people and send further instructions

EDIT: I would love to hear some suggestions about what people would like these things to be capable of. For example should I allow the speed at which they expand be changed as well as how far they expand? Lemme know what you would like to see and I'll try and fit them all in

EDIT 2: I'll probably release it to the public but have it marked as BETA at first. People that are willing are highly encouraged to let me know when it bugs out/glitches/breaks. If you run across these things please try and include how you did it so I can try and reproduce it.
NINJA EDIT 3 WITH THE DOWNLOAD LINK COMING.... not Sunday. Looking for someone to help me sort out the 3D model
