Combining Raycast with Dotproduct

[testingacc333330 (testingdev333330)]

Hello!

I’m currently making a line of sight system and i got it to work in only one axis.

The reason is that im utilizing a single ray raycast and then i noticed that there is something called “DotProduct()”

How could i get to combine dotproduct into this code:

local part = script.Parent.Head
local rayDirection = part.CFrame.LookVector * 30

while task.wait() do
	local raycastResult = game:GetService("Workspace"):Raycast(part.Position, rayDirection)
	local params = RaycastParams.new()
	params.FilterType = Enum.RaycastFilterType.Blacklist
	params.FilterDescendantsInstances = script.Parent:GetChildren()
	if raycastResult and game.Players:GetPlayerFromCharacter(raycastResult.Instance.Parent) then
		print("found ".. raycastResult.Instance.Name)
	else
		print("wheres")
	end
end

(ik im using a outdated raycast system and using task.wait(), you can fix it if you want to)

Are you wanting the “widen” the line of sight from the part, or are you wanting to check if the part is in the player’s view if hit?

I guess “widen” whatever that is supposed to be

I’m not entirely sure what you mean, but I’m guessing you want to try to establish a field of vision. If so this is useful:

How to check if an object is within an angle of the front of a player’s characters?

The first thing you want to do is to work out which direction the player’s character is facing: local Facing = Character.HumanoidRootPart.CFrame.LookVector Then you want to get the direction from your character to the object: local Vector = (Object.Position - Character.HumanoidRootPart.Position).unit Then you can get the angle between those two vectors using the equation:

What this means is that the cosine of the angle between vectors u …

You can find the angle between object1 and object2 using the dot product and compare it with an arbitrary max angle value.

I’m not really sure how you want to incorporate rays into this to be honest, unless you want something else.
