Can someone please tell me a good way of making the same physics system the knife from this game uses?
I’ve tried everything but I can’t make it rotate like that
Did you eventually found a way? I am currently struggling with the same type of mechanic(
Dude, did you find a way eventually?
No, not even close.
Still trying to find a way
There is no chance of this being realtime slicing. Instead it’s likely they’re just rendering each object to be sliced twice with a cross-section shader (for example https://assetstore.unity.com/packages/vfx/shaders/cross-section-66300)
When the knife collides with the object a hidden copy is enabled and shown in the same place. Both are then given different cross section settings and physics are then enabled.
This is highly efficient and requires very little technical knowledge to implement.
If you mean the knife then it’s pretty basic, and a set of slerp targets would do it. The only thing physical about that knife is probably a hidden sphere collider so it only begins to cut when it is moved to a favourable position. It is all faked as far as physics go.
