/prog/ - What an awesome programming language

Name: Anonymous 2012-10-09 14:34

Pretty much any language other than C#:



  gun.transform.localPosition.x = newPos;

C#:



  gun.transform.localPosition.x = newPos;



error CS1612: Cannot modify a value type return value of `UnityEngine.Transform.localPosition'. Consider storing the value in a temporary variable

Suggested C# workaround:



  gun.transform.localPosition.x = new Vector3(newPos, gun.transform.localPosition.y, gun.transform.localPosition.z);

this is why javascript is the future; operator overloading actually works correctly

operator overloading
It would be a great improvement if operator overloading was where C# fell apart... C# can't even handle operators. Just simple assignment is illegal.

thats pretty much the only flaw in c#

except you have to be fucking with properties to create that kind of assignment issue:



        [TestMethod]

        public void TestMethod1(){

            var t = new Test();

            t.TestVec = new Vector3();

            t.TestVec.X = 5;//wont  compile

            

        }



        class Test{

            public Vector3 TestVec { get; set; }

        }

Saying that being unable to assign values to variables is "pretty much the only flaw" in a language is like saying that the writing, acting, and directing were pretty much the only flaws in Battlefield Earth.

Do you not understand the different between getting a member by reference, and getting a member by value?

The only issue is that it makes perfect sense. Op is using a struct type in a getter/setter scenario. The following example should help it make some sense. The equivalent code in C++ would be:



int main(){

    ContainerClass c = new ContainerClass;

    c.SetVec( new Vector3(x,y,z));

    c.GetVec().X = 5;//since GetVec returns a valuetype, changing X to 5 has no affect on the Vector3 in ContainerClass

        //in order to prevent former java programmers from fucking themselves over because they don't know about structs, this would raise a compile error in C#

}



class ContainerClass{

private Vector3 _vec;//vector3 is a struct



public Vector3 GetVec(){return _vec;}

public void SetVec(Vector3 vec){_vec = vec}



}

The reason Java doesn't have this praoblem is that it treated everything as a reference type, the only value types are int, float, double, etc.

OP, the actual fix to your issue is to make gun.transform.localPosition a reference type, rather than a value type.

goddamn and to think c# is nice enough to throw a compile error for you, op. god speed programming in c++ or in any other language that doesn't hold your hand.

What I hate about Sepples, is the fact that everyone says I should make all attributes private and define getters/setters for each one.
This is dumb as fuck. The property() function used in Python is much better.

c# has eval too!

public static object Eval(string sCSCode) {

    CSharpCodeProvider c = new CSharpCodeProvider();

    ICodeCompiler icc = c.CreateCompiler();

    CompilerParameters cp = new CompilerParameters();



    cp.ReferencedAssemblies.Add("system.dll");

    cp.ReferencedAssemblies.Add("system.xml.dll");

    cp.ReferencedAssemblies.Add("system.data.dll");

    cp.ReferencedAssemblies.Add("system.windows.forms.dll");

    cp.ReferencedAssemblies.Add("system.drawing.dll");



    cp.CompilerOptions = "/t:library";

    cp.GenerateInMemory = true;



    StringBuilder sb = new StringBuilder("");

    sb.Append("using System;\n");

    sb.Append("using System.Xml;\n");

    sb.Append("using System.Data;\n");

    sb.Append("using System.Data.SqlClient;\n");

    sb.Append("using System.Windows.Forms;\n");

    sb.Append("using System.Drawing;\n");



    sb.Append("namespace CSCodeEvaler{ \n");

    sb.Append("public class CSCodeEvaler{ \n");

    sb.Append("public object EvalCode(){\n");

    sb.Append("return " + sCSCode + "; \n");

    sb.Append("} \n");

    sb.Append("} \n");

    sb.Append("}\n");



    CompilerResults cr = icc.CompileAssemblyFromSource(cp, sb.ToString());

    if (cr.Errors.Count > 0) {

        return null;

    }



    System.Reflection.Assembly a = cr.CompiledAssembly;

    object o = a.CreateInstance("CSCodeEvaler.CSCodeEvaler");



    Type t = o.GetType();

    MethodInfo mi = t.GetMethod("EvalCode");



    object s = mi.Invoke(o, null);

    return s;

}

While this is actually helpful information (as such, not sure why it was posted on /prog/), OP can't make the suggested fix because:

UnityEngine.Transform.localPosition

This is apparently part of the Unity engine, and the developer doesn't have access to the source. Probably.
