[Solved] Hitbox Raycast Problem?
I'm making a fighting game (another jojo game) and I'm having problems with making a hitbox using raycast. It's saying that the variable "CastResults" == nil
Extra Information: The variable "Stand" is a model, containing R6 Rigparts, it's primarypart is the HumanoidRootPart
My failed output:
ServerScriptService.StandServerHandler:233: attempt to index nil with 'Instance'
My raycast code:
local RaycastParameters = RaycastParams.new()
RaycastParameters.FilterType = Enum.RaycastFilterType.Blacklist
RaycastParameters.FilterDescendantsInstances = {Stand, Character}
RaycastParameters.IgnoreWater = true
local CastResults = Workspace:Raycast(Stand.PrimaryPart.CFrame.Position, Stand.PrimaryPart.CFrame.LookVector * 500, RaycastParameters)
local Hit = CastResults.Instance -- Line 233
local HitPosition = CastResults.Position
local Surface = CastResults.Normal
local Material = CastResults.Material.Name

You don't need [Unsolved] in your title. :) WideSteal321 773 — 4y

The mathematics used to draw the ray is likely the root of your issue. If your RaycastResult Object is nil, the ray didn't make contact with an Instance; it's best to account for this in the future. Ziffixture 6913 — 4y

The raycast result not aways returns something, it can be nil if the ray did not find anything and ur code stops working after that.
Just check it out with
if CastResults then
local Hit = CastResults.Instance
local HitPosition = CastResults.Position
local Surface = CastResults.Normal
local Material = CastResults.Material.Name
end
