How to get the length of Intersection of a block with a ray?

[SIayec (Daniel)]

this Picture from Topic describes what I need.

I want to get the length of Intersections between the two parts, or the magnitude between both the intersections.

You can use the .Position property of a RaycastResult to know where the intersection positions are and calculate accordingly (via Magnitude). For the first part hit, you could (with raycast params) blacklist the part that was hit, and raycast again using the same direction as the first ray cast, thus getting your 2 points

Bullet doesn't like to go through parts who's X or Z size is lower than 2?

This doesn’t answer your question, but it might help you: An easier way to do bullet penetration might be to move forward a bit, raycast backwards (with a whitelist of only the part you hit), and check where the exit point is. Then you can just check the distance between those. Something like this: -- returns entry and exit point local function RaycastEntryExit(origin: Vector3, dir: Vector3, raycastParams: RaycastParams): (Vector3|nil, Vector3|nil) local result = workspace:Raycast(origin, di…
