Question about camera

[KirillWd]

Hey, Everyone! My question is how can I record the camera's position?

Why doesn't it work?

  
[b]function[/b] trace(player) 
     [b]local [/b]x, y, z = getCameraMatrix(player) 
     [b]outputChatBox[/b]("x: "..tostring(x).."; y: "..tostring(y).."; z: "..tostring(z), player) 
[b]end[/b] 
----- 
[b]addCommandHandler[/b]("t", trace) 
  

It always prints:

x: false; y: nil; z: nil

I don't understand why x is false, y and z are undefined. Please, help!

Why tostring? Maybe tonumber is better

[TAPL]

are you sure you have put it as server side in meta?

[Jaysds1]

actually, the values could go in with out using "tostring" or "tonumber".

anyways, make sure this is server-sided.

if it still doesn't work, try this:

function trace(source) 
    local x, y, z = getCameraMatrix(source) 
    if x and y and z then 
        outputChatBox("Your Camera Positions are x: "..(x).."; y: "..(y).."; z: "..(z),source) 
    else 
        outputChatBox("Test!!!",source) 
        local x1,y1,z1 = getElementPosition(source) 
        setCameraMatrix(source,x1,y1,z1+3,x1,y1,z1) -- this would set the camera looking down at you 
        x, y, z = getCameraMatrix(source) --replace the current vars 
        outputChatBox("Your Camera Positions are x: "..(x).."; y: "..(y).."; z: "..(z),source) 
        setTimer(setCameraTarget,7000,1,source,source) 
        setTimer(setCameraTarget,7000,1,source,source) 
    end 
end 
addCommandHandler("t",trace)

yep, this file is on server-side.

Jaysds1, that isn't i want. yeah, this work, but everytime camera's x (either y) are the same of player's x (and y). I needn't know the player's position, but camera's. If change the position after the first time, there is the test again.

Why does it happen?

[Jaysds1]

well, it seems like you could only get the camera matrix if it's set first.

Do you want a joke? This script works on client-side and doesn't on server-side. so

-- <script src="script.lua" type="client" /> 
[b]function[/b] trace() 
    local x, y, z = getCameraMatrix() 
    outputChatBox("x: "..math.ceil(x).."; y: "..math.ceil(y)) 
[b]end[/b] 
addCommandHandler("t", trace) 
-- works! 
  

Nevermind, I've understood I don't need server to know camera's position of all players. Well, the task is completed. Anyway, thx to everyone who has tried to help!

For your information, server-side getCameraMatrix will return the values you previously set with setCameraMatrix, you will not get position of player's camera unless you set it first. That's because server doesn't need to update this information every tick, this would lag the server and eventually freeze it.
