Best way to check if a position is inside of a part

[Carrotoplia (Carrotopliani)]

Right now im making a no clip check and im needing to check if a position is inside of a part
how would I detect if a position is inside a part
not a part inside another part but some math to check if its inside or not

found this, dunno if it helps

How do I get a player from a zone?

If you are using an invisible/non-collide brick to define your region, here is a function that can determine if a given Vector3 position is inside of it: function isInsideBrick(position, brick) local v3 = brick.CFrame:PointToObjectSpace(position) return (math.abs(v3.X) <= brick.Size.X / 2) and (math.abs(v3.Y) <= brick.Size.Y / 2) and (math.abs(v3.Z) <= brick.Size.Z / 2) end This should work regardless of the hitbox’s rotation.

Try looking into GetPartBoundsInBox and GetPartBoundsInRadius.

function isPointInVolume(point: Vector3, volumeCenter: CFrame, volumeSize: Vector3): boolean
    local volumeSpacePoint = volumeCenter:PointToObjectSpace(point)
    return volumeSpacePoint.X >= -volumeSize.X/2
        and volumeSpacePoint.X <= volumeSize.X/2
        and volumeSpacePoint.Y >= -volumeSize.Y/2
        and volumeSpacePoint.Y <= volumeSize.Y/2
        and volumeSpacePoint.Z >= -volumeSize.Z/2
        and volumeSpacePoint.Z <= volumeSize.Z/2
end

function isPointInPart(point: Vector3, part: BasePart): boolean
    return isPointInVolume(point, part.CFrame, part.Size)
end

Should work, can’t test it right now. You might want to use > and < instead depending on your needs.
