So I’ve been using FastCast for my guns, and I wanted to implement bullet accuracy to make it look a bit more natural.

This is my code:

```
function bulletSpread(maxAngle, direction)
--maxAngle is a number, direction is a vector
--Get random angles for both axis first
local yAngle = math.random(-maxAngle * 10, maxAngle * 10) / 10
local xAngle = math.random(-maxAngle * 10, maxAngle * 10) / 10
--my Current solution: get the offset from the baseCframe, and then apply it to the calculated vector
local unitVector = direction.Unit
local baseCframe = CFrame.new(0, 0, 1) --Ew
local dirCframe = CFrame.new(direction)
local offsetCframe = baseCframe:Inverse() * dirCframe
--Now use trigonometry to convert into new vector
--Im using Cframe (0,0,1) becoz im gonna change it on x and y axis, so its kinda intuitive to leave the z untouched
--it wont remain a unit vector after this, but that has no effect so i dont care
local y = math.tan(math.rad(yAngle))
local x = math.tan(math.rad(xAngle))
local adjustedCframe = CFrame.new(x, y, 1)
local finalCFrame = adjustedCframe * offsetCframe
local newVector = finalCFrame.Position
return newVector
end
```

(I’m calculating the offset from a base Cframe, because the player can fire in any direction and my brains are unable to directly apply the spread to the provided vector)

This works, but I’m not happy with having to do this, because I feel like there is a way to apply the spread directly. I will much appreciate any help in doing this, thank you.
