How to print Mouse.Hit.p without error of hit.p being a userdata value?

Asked Jul 22, 2019257 views2 answers

local UIS = game:GetService("UserInputService")
local Players = game:GetService("Players")
plrs = {}
for i,v in pairs(game.Players:GetChildren()) do
table.insert(plrs,v:GetFullName()
end
for i = 1,#plrs do
local mouse = plrs[i]:GetMouse()

local function onInput(inputObject, gameProcessed)
    if gameProcessed then return end

    if inputObject.UserInputType == Enum.UserInputType.Touch then
    target = mouse.Hit.p
 print(mouse.Hit.p)
    end
end

UIS.InputBegan:Connect(onInput)

Okay - I understand something else might error because I compiled this script at like 2 AM. When I try to print "mouse.Hit.p", it gives me an error stating that you cannot print a userdata value. Is there any fix to this? Help is greatly appreciated.

To convert userdata to a string, we can use a built-in roblox LUA function called tostring(). In your case, it would be used as so:

local UIS = game:GetService("UserInputService")
local Players = game:GetService("Players")
plrs = {}
for i,v in pairs(game.Players:GetChildren()) do
table.insert(plrs,v:GetFullName()
end
for i = 1,#plrs do
local mouse = plrs[i]:GetMouse()

local function onInput(inputObject, gameProcessed)
    if gameProcessed then return end

    if inputObject.UserInputType == Enum.UserInputType.Touch then
    target = mouse.Hit.p
 print(tostring(mouse.Hit.p))
    end
end

UIS.InputBegan:Connect(onInput)

As seen on line 15, we added the tostring function inside of print() with the argument as what we want to convert to a string. It should now either print the proper vectors or nil if your pointing at the sky. With further questions regarding this topic, feel free to reply to my post.

My pleasure!

Line 5 needs to change to

table.insert(plrs,v)

:GetFullName() returns a string and not the actual instance, thus failing to capture the mouse on line 8. GetMouse() can only be called from a player and not a string.
