[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:
1 | ServerScriptService.StandServerHandler:233: attempt to index nil with 'Instance' |
My raycast code:
01 | local RaycastParameters = RaycastParams.new() |
02 | RaycastParameters.FilterType = Enum.RaycastFilterType.Blacklist |
03 | RaycastParameters.FilterDescendantsInstances = {Stand, Character} |
04 | RaycastParameters.IgnoreWater = true |
05 |
06 | local CastResults = Workspace:Raycast(Stand.PrimaryPart.CFrame.Position, Stand.PrimaryPart.CFrame.LookVector * 500, RaycastParameters) |
07 |
08 | local Hit = CastResults.Instance -- Line 233 |
09 | local HitPosition = CastResults.Position |
10 | local Surface = CastResults.Normal |
11 | 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
1 | if CastResults then |
2 | local Hit = CastResults.Instance |
3 | local HitPosition = CastResults.Position |
4 | local Surface = CastResults.Normal |
5 | local Material = CastResults.Material.Name |
6 | end |
