BroadcastMessage Null Reference Exception Problem

Questions & Answers
1

I have this piece of code here which is a part of an administrative console i am making.
I tried to give the user a bit more freedom as to what type the BroadcastMessage Parameters are.

consoleInterpretation=consoleText.Split("."[0]);
if(consoleInterpretation[0]=="Find"){
if(consoleInterpretation.length==4){
var typeSplit2:String[];
typeSplit2=consoleInterpretation[3].Split(":"[0]);
if(typeSplit2.length==2){

if(typeSplit2[1]=="int")
GameObject.Find(consoleInterpretation[2]).BroadcastMessage(consoleInterpretation[2],int.Parse(typeSplit2[0]));
if(typeSplit2[1]=="float")
GameObject.Find(consoleInterpretation[2]).BroadcastMessage(consoleInterpretation[2],float.Parse(typeSplit2[0]));
if(typeSplit2[1]=="String")
GameObject.Find(consoleInterpretation[2]).BroadcastMessage(consoleInterpretation[2],typeSplit2[0]);
if(typeSplit2[1]=="GameObject")
GameObject.Find(consoleInterpretation[2]).BroadcastMessage(consoleInterpretation[2],GameObject.Find(typeSplit2[0]));
else
GameObject.Find(consoleInterpretation[2]).BroadcastMessage(consoleInterpretation[2],typeSplit2[0]);
    }
    else
GameObject.Find(consoleInterpretation[2]).BroadcastMessage(consoleInterpretation[2],consoleInterpretation[3]);
}
else 
GameObject.Find(consoleInterpretation[1]).BroadcastMessage(consoleInterpretation[2]);
}

When i type "Find.MyGameObject.AddPoints.8:int" i get the following error

NullReferenceException
UnityEngine.GameObject.BroadcastMessage (System.String methodName, System.Object parameter) (at C:/BuildAgent/work/842f9557127e852/Runtime/ExportGenerated/Editor/UnityEngineGameObject.cs:287)

A Debug.Log line i added showed me that typeSplit2[0]=“8” and typeSplit2[1]=“int”
Any ideas as to what might be the problem?

EDIT:
Now even if i type Find.MyGameObject.SampleFunction.text
Where: SampleFunction(test:String)
It gives a null reference exception

You assume that whatever they type and ends up in consoleInterpretation[2] is going to be valid. I wouldn’t. Do a Find on that, check the result for null (didn’t find), and put up an error message if so. Then use that var you got back instead of consoleInterpretation[2] all over the place. In fact, check all user input for validity before trying to broadcast it.

Re 'typeSplit2[0]=“8” and typeSplit2[1]=“int” ': that’s right. Split on “.” gives you

[0] Find
[1] MyGameObject
[2] Addpoints
[3] 8:int

[3] split on “:” gives

[0] 8
[1] int

“Find.MyGameObject.SampleFunction.text Where: SampleFunction(test:String)” split on “.” gives:

[0] Find
[1] MyGameObject
[2] SampleFunction
[3] text Where: SampleFunction(test:String)

and [3] split on “:” gives

[0] text Where
[1]  SampelFunction(test
[2] String)
