local variable? Can anyone help me with this one? I have the two lines below, just two.. and I get the following error: error CS0165: Use of unassigned local variable 'pipesStart' I'm wracking my brains over this one, as this to me is correct. void Start () { float[] pipesStart; pipesStart[0] = 0.0f; } Comment Add comment 10 |3000 characters needed characters left characters exceeded ▼ use of unassigned local variable c# string Viewable by all users Viewable by moderators Viewable by moderators and the original poster Advanced visibility Viewable by all users 1 Reply · Add your reply Sort: 2 Best Answer Answer by Piflik · Jan 14, 2013 at 09:13 PM You have declared an array, but never initialized it. What is stored in an array variable is actually just a pointer to a memory address, but you never allocated the memory you need for that aray. The vlue in your pipesStart variable is 'null', and you cannot do anything with 'null'. float[] pipesStart = new float[10]; //for an array with length ten...use whatever number you need...note: arrays cannot be resized Comment Add comment · Show 2 · Share 10 |3000 characters needed characters left characters exceeded ▼ Viewable by all users Viewable by moderators Viewable by moderators and the original poster Advanced visibility Viewable by all users curv · Jan 14, 2013 at 09:16 PM 0 Share ah.. But I'm not sure how large this array will be. Does it need to become an ArrayList at this point? Piflik · Jan 14, 2013 at 09:38 PM 0 Share If you don't know how long the array h

On one of my scripts unity straight up refuses to recognize a public variable as such, I've tried restarting several times and every time I get the same error. Here is a bit of the script in question. public class BreakObject : MonoBehaviour { public GameObject broken; void Update () { As that clearly shows 'broken' is a public variable yet no matter http://answers.unity3d.com/questions/755095/c-assetsbreakobjectcs2062-error-cs0165-use-of-unas.html what I try unity refuses to recognize that it is and insists on treating it as a local variable. Anyone had this problem or know how to fix it? It's really annoying that I can't go on with my project. Thanks for your help!

Any chance you are declaring this variable again inside a function? For example if you did this: public class BreakObject : MonoBehaviour { public GameObject broken; void Update () { GameObject broken; broken.transform.positon = Vector3.zero; } } ...your code would generate the error.

If I call MyObject o; if (objects != null && objects.TryGetValue(objectName, out o)) v.Property= o; then everything is fine. The following two cases however give me an error, and I'm not quite understanding why. MyObject o; if (objects != null ? objects.TryGetValue(objectName, out use of unassigned o) : false) v.Property= o; // <-- error CS0165: Use of Unassigned local variable 'o' and MyObject o; bool b; if (objects != null) b = objects.TryGetValue(objectName, out o); else b = false; if (b) v.Property = o; // <-- error CS0165: Use of Unassigned local variable 'o' In either of the last 2 cases, I don't see how o can be used unless TryGetValue is called, which means o should be initialized. Is this a bug? Or I am I missing something?

Here's a simple repro case: ===== Test.cs ===== public class A { public static A Get() { return null; } } public class Test { void M() { A A = A.Get(); } } ===== End of Test.cs ===== ===== Sample command lines ===== # From Visual Studio 2013 command prompt: $ csc /target:library Test.cs Microsoft (R) Visual C# Compiler version 12.0.21005.1 Copyright (C) Microsoft Corporation. All rights reserved. [No errors] # From Mono 2.10.9 command prompt: $ mcs /target:library Test.cs [No errors] # From Mono 3.2.3 command prompt: $ mcs /target:library Test.cs Class1.cs(10,15): error CS0165: Use of unassigned local variable `A' Compilation failed: 1 error(s), 0 warnings ===== End of sample command lines ===== Thus, this source file is compiled by csc and mcs version 2.10.9. mcs 3.x fails to compile this code. This looks like a regression between the 2.x and 3.x series of the mcs compiler. Thanks, Richard.
