What I want the results to be.
I want my knife throws to be more accurate. The problem is detecting when the knife is touched and how the knife throw can go perfectly straight. It works great with damaging NPC and players, but what I’m concerned with is when the knife touches a wall or object and the direction of the knife.
What happens.
I used the touched event in the same way as the damaging function, yet yielded terrible results. I threw the knife at a wall, and the knife doesn’t even touch the wall by the time it is anchored. The knife went through the wall because cancollide was off, but then anchored and kept floating in the air. When I threw the knife, the direction of the knife was terrible too, it kept facing sideways and not forward to the target.
What I tried to fix it.
I went searching on the dev forum and saw Region3 and GetTouchingParts(), but didn’t even know how to use them. I tried doing the touching parts thing, but it doesn’t work on cancollide objects. I tried looking at region3 and was immediately confused, but then saw on a dev forum about the region3 saying that touched was better than region3 in my situation. Then I went searching on the dev forum even more and found out that touched is terrible when it comes to high-speed moving objects.
Here’s the knife throw script.
Note: The require at the first line of the code is really useful, it’s basically merging a local script and a script, allowing you to do game.Players.LocalPlayer on a script.

Just let me know my mistake, how I can fix it, and if you want to, send me some compatible code (non-mandatory). For those asking, yes this is a Jojo script.
