@mikeNspired it is indeed cutting a solid mesh dynamically at runtime. Unity allows manipulation of mesh vertices and textures at runtime. There are a few mesh cutting tools out there, the one I used is called Shatter Toolkit which can be found on the asset store. From there, it was simply a matter of converting the planar cuts from 2D XY (with mouse) to 3D with appropriate rotation angles. Currently, when you cut, it will always make a straight cut (planar cut), which is actually quite difficult to do when cutting with a real sword, so in a way, you are cutting as a master swordsman as a result. If I were to expand on this game idea, I would like to figure out how to make curved cuts work with dynamic meshes, which is something that doesn't seem possible currently or at least is very difficult. This way, you can actually get rated on the quality of your cut, whether it was a clean/straight cut, or whether it curved or changed direction through the target.

How did you get the dynamic cutting of a static mesh? Is that unique to Unity at the moment? Or are you somehow faking the cutting like alot of cutting games. I just know it's not possible right now in Unreal Engine for real dynamic mesh cutting in real time. Everything has to be pre-cut, or replace the geometry with 2 new geometry.

@johnjoemcbob Thanks for the comments, I updated this so the menu works with the Leap Motion. I also improved the Thrown Tatami gameplay - should be a bit easier/nicer to cut now.

Very cool game. I enjoyed trying to make as many cuts as possible in the stationary mode, and trying to hit every tatami in the thrown mode. It's nice to have the stationary mode to play around with the destruction & the thrown mode to add some challenge. Controlling the katanas with my hands felt awesome, I really like the audio/visual feedback when you swipe with them. The background art looks good and fits well with the theme. It would be cool to have the ability to interact with the menus with the Leap rather than using a mouse. Also some sort of scoring system on the thrown mode would be awesome!

Overall a really polished game, well done!
