How do I find Ray Closest Point?

[ryanadamdragon (Dragon)]

I am using the new rays (workspace:raycast())
I want to find the Closest point of something to the ray like Ray:ClosestPoint().
BUT… only the deprecated raycast has that built-in function. I want to use the new raycast. How do I do it?

deprecated raycast

That is semi-incorrect, what is deprecated is the FindPartOnRay function which is right.

However the actual ray object is not deprecated as seen here. It’s just a data type with a neat built in function.

So you just go ahead make the ray then use the closest point function.

workspace:raycast(origin, direction)
local ray = Ray.new(origin, direction.Unit)--make sure to .Unit for closest point to work

Or you can use the mathematical method here:

Calculating closest point on a line?

Just in case you were wondering the way you could have found a point on a line given the distance returned from the function you provided, would be (one way) to use the Pythagorean theorem to find the length of the adjacent side of the triangle given the distance from the line and the distance from the start of the line so that: math.sqrt((FromStart^2)- (Distance^2)) is the length of the adjacent side , where FromStart is the distance from a and v and Distance is the distance returne…
