Hello wonderful devforum people!
I’m helping my friend get some of the systems in their game started off. For context, if you know what JoJo’s is this will be a simpler read, but if you don’t then just remember that the use of “Stand” just represents the NPC that I’m trying to weld to the player.
Anyway! My goal going in was for animations with the player and their Stand to be independent from each other. I also wanted the player to spawn in with their Stand always connected to them, so this script serves solely to weld their Stand to them. The way I accomplished this was the only way that made sense: welds, and in this case rigid constraints, which both got me the same bugged-out result…
In StarterCharacterScripts:
--// Variables
local rs = game.ReplicatedStorage
local standbase = rs:WaitForChild("StandBase")
local char = script.Parent
local plr = game.Players:GetPlayerFromCharacter(char)
--// Functions
function InjectStand()
local charstand = standbase:Clone() -- copying the stand uniquely
charstand.Name = (char.Name.."Stand")
charstand.Parent = char
local standroot = charstand.HumanoidRootPart
standroot.Anchored = false
standroot.CFrame = char.HumanoidRootPart.CFrame
local rigid = Instance.new("RigidConstraint") -- establishing the constraint itself
rigid.Name = "StandRigidConstraint"
rigid.Parent = char
rigid.Attachment0 = char.HumanoidRootPart.RootAttachment
rigid.Attachment1 = standroot.RootAttachment
end
InjectStand()
This is a remarkably simple script, and I wasn’t expecting to have to troubleshoot it. But it seems that the problem lies with a core part of the Roblox engine. For some reason, when you have two characters welded together, they completely ignore the Massless property which, in this case, means that my player is very weighed-down and slow. CustomPhysicalProperties “Density” set to zero achieves an identical result as well.
I searched for solutions on the devforum, and most of these cases came up with no solution or a solution that just didn’t work at all in my case.
For example, in an old devforum post (that for some reason I can’t find right now) the solution to the massless issue was apparently changing the root part’s name… I tried changing part of the code to this.
local standroot = charstand.HumanoidRootPart -- need a var bc of what we're bout to do
standroot.Name = "_HumanoidRootPart" -- ro engine gets confused with connected humanoids so we use a hacky fix???
standroot.Anchored = false
standroot.CFrame = char.HumanoidRootPart.CFrame
Same result, so I didn’t keep this.
If anyone could offer some pointers, troubleshooting options, or solutions of any kind I would be very grateful. Thank you!
