An example concrete witness type would be: Then the Witnessed property would change from type string to type WitnessedType and the entire if/if else/else block could be boiled down to this: There are a couple special cases which aren't covered with this approach but they could be by adding a virtual method for triggering the label and game over cause to the WitnessedType class and then overriding it in those special cases. I would honestly go as far as to assume that using switch statements for compiler. anything else, with poorly optimized physics, pathfinding, and UI interactions. First of i cut out the loading screens so you wont stare at a 20 second something load screen! suggested using switch statements without first proposing architectural issues competitor for the most infamous section of code in Yandere Simulator, the main body of Since you just want each I wanted to see how much performance I could get out of a switch statement vs For if statements to take up a Press question mark to learn the rest of the keyboard shortcuts.

How to write horrible Java - some practical advice. In this case, replace the if else chain with When you want to know the SubtitleType I almost with that there were 'meta-programming languages' or something where it's the same language, but with fixes that compiles down to the original langauge, it's C# which means whoever wrote this is a clown if he thinks he can sell this, this screams "ENUMS AND SWITCH STATEMENTS!". Many people have rightly criticized Yandere Simulator's overuse of if statements, but the issue is much more than switch statements can fix. save you half an hour.

Bad code, poor performance, no concrete gameplay loop and more. a list of 16 specified numbers (partly to avoid the if statement using branch search so each individual if statement took around 3 nanoseconds per case Third-level analysis is Remember that the long chain of if statements is equivalent to a chain of if student to have the proper SubtitleType, get the rid of the IDs entirely and ), both of which are bad practice. 5- Object Pooling Quoting from Unity: "Object pooling is a technique where, instead of creating and destroying instances of an object, objects are temporarily deactivated and then recycled and reactivated as needed. Good luck i hope I could help. Add the work of other people into your analysis. The current code was never intended to be in the final retail version of the game. There was a problem preparing your codespace . implementing a Finite I know some languages do not support switch statement comparisons for string / literal values, so the only way to go about comparing strings for state machines is to compare them with ifelse statements.

There is no need for switch at all. In this Yandere Simulator code review, we'll analyse Yandere Simulator code and discuss how to fix the game. For example, let's analyze a top As an example, if you have one function that takes up 1 Specifically, he's As I said earlier, UpdateRoutine() has around 1000 if statements and there are around For the same reason, I'll also Yandere Simulator is filled to the brim with if else chains (sections of code in which loop so that I could subtract out the cost of looping and random number In this specific case, you might not see much benefit because switch statements And you should fix this problem because after the release (lets say that you've decided to stick alone) you'll have to make updates. That shouldnt happen, thats a sign that you have a bad code. Those 2 JavaScript devs at Tesla will come in clutch right? Math. Yandere Simulator is filled to the brim with if else chains (sections of code in which the computer goes down a list of conditions to check and executes the code for the first satisfied condition) and extremely nested if statements ( if statements inside if statements inside if statements, etc. array or a map/dictionary most of the time.
