Raycast between two areas or on a surface?

[telebama (Bload)]

I’m doing something that requires raycasts for collision. I want to know how I could cast multiple rays along a surface or between two positions.
If it helps my current raycasts are working fine, it’s just that right now I only have them casting from the corners of the block.
I’m grabbing the corners through this:

local c1 = Vector3.new(charcol.Position.X - charcol.Size.X/2, charcol.Position.Y + charcol.Size.Y/2) -- top left
local c2 = Vector3.new(charcol.Position.X + charcol.Size.X/2, charcol.Position.Y + charcol.Size.Y/2) -- top right
local c3 =  Vector3.new(charcol.Position.X - charcol.Size.X/2, charcol.Position.Y - charcol.Size.Y/2) -- bottom left
local c4 = Vector3.new(charcol.Position.X + charcol.Size.X/2, charcol.Position.Y - charcol.Size.Y/2)  -- bottom right

I don’t think there’s a way to get specific locations of a face of a part, especially for parts with more complex geometries. In the meantime, check out this thread on Fibonacci spheres:

Generating Equidistant Points on a Sphere

[image] Generating Equidistant Points on a Sphere In this post, I’ll be covering how to generate points in 3D space that are equally spaced on the unit sphere. The method is based on a spiral walk of the spherical surface in angular increments equal to the golden angle. At the end of this post, I’ll also briefly go over some potential uses in your games, and what I’m personally using it for. 1. The Golden Ratio Let’s first illustrate what the golden ratio is. Say you have a line segment a, a…

Also, I’m sure you could just use spatial queries for your collision system instead, it would be much simpler and perhaps more performant than running hundreds of raycasts
