Not All Code Paths Return A Value C# Mvc
Your code doesn't make sense but the error message is quite clear. You need to return a value even if both your if conditions are false for 20 iterations. –ChaosPandion Jan 17 '14 at 20:52 4 You're thinking like a human, not a compiler. The compiler doesn't know what you are thinking, or how the logic is supposed to flow (past optimization). What happens if a value doesnt match either 'if'? –GrandmasterB Jan 17 '14 at 21:08 add a comment| 6 Answers 6 active oldest votes up vote 34 down vote You're missing a return statement. When the compiler looks at your code, it's sees a third path (the else you didn't code for) that could occur but doesn't return a value. Hence not all code paths return a value. For my suggested fix, I put a return after your loop ends. The other obvious spot - adding an else that had a return value to the if-else-if - would break the for loop. public static bool isTwenty(int num) { for(int j = 1; j <= 20; j++) { if(num % j != 0) { return false; } else if(num % j == 0 && num == 20) { return true; } } return false; //This is your missing statement } share|improve this answer edited Jan 18 '14 at 14:01 answered Jan 17 '14 at 20:53 GlenH7 1,5971531 1 This returns the wrong result for isTwenty(44696171520). It should return true becase it can be evenly divided by all numbers 1 to 20, but it returns false. In fact,

I'm trying to practice on coding and I got this problem: the console keeps saying not all code paths return a value! and simply my code is: public float InputGetAxis(string axis ){ float v = Input.GetAxis(axis); if(Mathf.Abs(v)>0.05f)return v; if(axis == "Horizontal")return axisH; } so anyone could help~ thanks Comment Add comment · Show 3 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 robertbu · Feb 03, 2014 at 06:46 AM 0 Share You don't provide enough of the script for us to show you exactly what is wrong. The problem is that there is a pathway through your logic that does not end with a 'return'. For example in the code above, what happens if 'Mathf.Abs(v) booyaa · Feb 03, 2014 at 06:59 AM 0 Share It looks like your function does the following: accepts a string called access and will return a float value. the first if returns the value of Input.GetAxis(axis) the second if returns axisH (presumably this is a public variable within the class? what happens if axis fails to meet both if statements? what do you expect to return? ffxz7ff · Feb 03, 2014 at 07:01 AM 0 Share This question has nothing to do with Unity, it's suitable for a noob programming forum and could easily be googled. Besides that the error code is very clear. 1 Reply · Add your reply Sort: 0 Answer by markmmiller · Feb 03, 2014 at 10:58 AM Your function InputGetAxis will not always return a value. You need to have a return statement outside of your if statements so that if those conditions are not met it will return a value. public float InputGe
