Detect if player is inside a sphere zone

I have an ability that spawns a huge sphere and the players inside it should experience an effect

But what’s the MOST EFFICIENT way of detecting it?

I know about bounding box thingy but im not sure if that works for a sphere?

Could probably use this

Alternatively, you can loop through all the players characters and check if the (CenterOfSphere - HumanoidRootPart.Position) < RADIUS, and if so then apply the effect. Dunno if this is very efficient though

Interesting, didn’t know about this function, it asks for a radius tho, how do i get the radius of the sphere i have?

#4

Well how is the sphere created?

In the script where you will try to access the sphere, how is the sphere defined? (put the code)

#7

I’d recommend you do:

The hitBox is the sphere zone in your case

#8

But that requires cantouch to be on right?

#9

Nope it can be false and it will still work

#10

not entirely sure what u mean… but

local function DetectLocalPlayerHit(part)
	workspace:GetPartBoundsInRadius(part.Position)
end

The radius of the sphere is just half the width (or height, or depth). So radius would just equal:

local Radius = Part.Size.Y/2

Note that this assumes that all dimensions are equal.

If they are not, use this instead:

local Radius = math.min(Part.Size.X Part.Size.Y, Part.Size.Z)/2

Worked like a charm!

(Excuse the video lag I had to run 3 roblox studio instances on my old computer I could literally smell my CPU melting)
