It is also just regularly used to make hitscan weapons for extra accuracy. It gives us a way to do many advanced things that would not be possible otherwise, like FastCast and raycast-simulated bullet physics. Raycasting is a really useful tool when it comes to Roblox scripting, almost necessary. To make raycasts avoid detecting certain objects, you would change the FilterType property like this: rParams.FilterType = Local raycastResult = workspace:Raycast(origin,direction,rParams) You pass the RaycastParams as the third value in the function Sets the FilterDescendantsInstances property of the object to a certain folder in the workspace Now, we need to pass it what objects should be counted. Sets the FilterType property of the object to Whitelist Any interaction between two objects occurs at some distance.

If it finds anything, it will return a RaycastResult object. This will raycast from the center of the world to a point above the center of the world. Local raycastResult = workspace:Raycast(origin,direction) Well, here is the basics of how it works: local origin = Vector3.new(0,0,0) What is raycasting? Well, Raycasting is making a line between two points and seeing what object the line intersects with first on it’s travel. Hello, and today I will teach you how to use raycasting, as well as many common use cases of it in Roblox development.
