This is sort of hard to explain, so let me try my best.
What I’m attempting to achieve is a system that raycasts a circle with a vector as the starting position, here is a picture of what I want in an over head view
I was attempting to use a for loop,
for i = 1, 360, 10 do
end
but I had no real luck with that, if anyone could help it’d be greatly appreciated!
Hi there, I think you should take a look at this: Circle and ellipse drawing algorithm - Math Open Reference
I took a look, I came up with this…
local Part = game:GetService("Workspace"):WaitForChild("CenterPart")
local h, k = Part.Position.X, Part.Position.Z
for i = 1, 360, 10 do
x = h + 10 * math.cos(i)
z = k + 10 * math.cos(i)
local part = Instance.new("Part")
part.Anchored = true
part.Size = Vector3.new(1, 1, 1)
part.Position = Vector3.new(x, Part.Position.Y, z)
part.Parent = workspace
part.BrickColor = BrickColor.new("Really red")
end
It resulted in this weird line.
You have to use radians when using math.cos or math.sin, so just put i in math.rad()
You have to use math.sin for x and math.cos for z, or vice versa, doesn’t really matter. You used the same function for both x and z, so you essentially made x and z equal.
Not much else needs to be done, I would think.
As I said before, you have to use math.rad to convert i to radians:
x = h + 10 * math.cos(math.rad(i))
z = k + 10 * math.sin(math.rad(i))
Quick note about your loop: it will go 1, 11, 21, …, 351. I imagine you probably didn’t intend it to work like that (although it will do the job just fine).
You can fix it like this:
for i = 10, 360, 10 do
-- loop body
end
This does beg the question… why are you doing this? Raycasting in the circle is generally a bad idea because there are better ways to do it. Is this for an explosion?
probably related to this thread, from the same OP.
I’ve made a place for you to check out, how I’d do it. It’s quite satisfying too watch.
