Converting string to Vector3 in Lua?

I've been trying for several hours to convert a string to a Vector3, but with no luck. I'm guessing I'm doing something horribly wrong to cause this.

Code:

function parseVector3(sourceString)
 
    local outString = string
    local outVector3 = UnityEngine.Vector3
    local splitString = string
  
    outString = string.sub(sourceString, 1, -14)
  
    splitString = string.rep(outString, 1, ",")   
  
    outVector3.x = tonumber(splitString[0])
    outVector3.y = tonumber(splitString[1])
    outVector3.z = tonumber(splitString[2])
    
    
    return outVector3
end

 

Code:

function parseVector3(sourceString)
 
    local outString = string
    local outVector3 = UnityEngine.Vector3
    local splitString = string
  
    outString = string.sub(sourceString, 1, -14)
  
    splitString = string.rep(outString, 1, ",")   
  
    outVector3.x = tonumber(splitString[0])
    outVector3.y = tonumber(splitString[1])
    outVector3.z = tonumber(splitString[2])
    
    local output = new Vector3(outVector3.x, outVector3.y, outVector3.z)
    return output
end

That returns the error:
"attempt to call global 'Vector3' (a nil value)"

 

Same error.

 

maybe this ?

Code:

vector = Utils.Vector3();
vector.x = outVector3.x;
vector.y = outVector3.y;
vector.z = outVector3.z;

 

Code:

function parseVector3(sourceString)
 
    local outString = string
    local outVector3 = Utils.Vector3()
    local splitString = string
  
    outString = string.sub(sourceString, 1, -14)
  
    splitString = string.rep(outString, 1, ",")   
      outVector3.x = tonumber(splitString[0])
    outVector3.y = tonumber(splitString[1])
    outVector3.z = tonumber(splitString[2])
    
    local output = Vector3:new(outVector3.x, outVector3.y, outVector3.z)
    return output
    
end
 

attempt to index global 'Utils' (a nil value)

 

Maybe this one?

Code:

function parseVector3(sourceString)
 
    local outString = string
    local outVector3 = new( UnityEngine.Vector3._type , nil )
    local splitString = string
 
    outString = string.sub(sourceString, 1, -14)
 
    splitString = string.rep(outString, 1, ",")
     outVector3.x = tonumber(splitString[0])
    outVector3.y = tonumber(splitString[1])
    outVector3.z = tonumber(splitString[2])
 
    return outVector3
 
end
