Preventing Unity3D IL2CPP from stripping your code

I was trying to get a list of a type's constructors at runtime using reflection, so that I could create an instance of the class using dependency injection. All worked just fine until we tried to build the app for iOS. At first we were using Mono as the scripting back-end, but it seems that new versions of iOS pop up a dialog telling the user the app is 32 bit and may run slowly (i.e. "Your app is crap"). When switching the backend scripting to IL2CPP (in File->Builder->Player Settings) the app suddenly wasn't working. It turns out that SomeType.GetConstructors().Count was returning zero, which was a problem because obviously I wanted to invoke those constructors with dependencies. The problem was that because these constructors weren't being calling explicitly from anywhere in my app IL2CPP decided I didn't need them, and stripped them out. The solution is to create a file in your Assets folder called link.xml and fill it in like so.... <lin

Forcing a device-orientation per scene in Unity3D

Unity3D has a Screen class with an orientation property that allows you to force orientation in code, which lets you have different scenes with different orientations (useful in mini-games). this works fine for Android but crashes on iOS. The problem is the file that gets generated during the build for iOS has an assert in it which inadvertently prevents this property from being used. It is possible to create a post-build class that runs after the iOS build files have been generated that can alter the generated code before you compile it in XCode. Just create a C# script named iOSScreenOrientationFix.cs and paste in the following code - adapted from  this Unity3D forum post . using UnityEngine; using UnityEditor; using UnityEditor.Callbacks; using System.IO; namespace Holovis { public class iOSScreenOrientationFix : MonoBehaviour { #if UNITY_CLOUD_BUILD // This method is added in the Advanced Features Settings on UCB // PostBuildProc

A UI thread dispatcher for Unity3D

I've recently been working on implementing an IHttpService that can work outside of a MonoBehaviour and call out to web services asynchronously. Rather than providing my IHttpService.JsonPost method with callbacks I decided to have it return a Promise, the code for which I took from this  Real Serious Games  GitHub repository. The problem is that when you use WebClient's async methods they call back the Complete events on the worker thread, so code like this won't work because you cannot manipulate UI from any thread other than the main one. httpService.JsonPost<MyInfo>(url)   .Then(myInfo => someTextUiObject.text = myInfo.Name); And there seems to be no kind of thread Dispatcher in Unity3D for UI updates as there is in Windows.Forms - so I wrote my own. using System.Collections; using System; using System.Threading; using System.Collections.Generic; using UnityEngine; public class UiThreadDispatcher : Singleton<MonoBehaviour> {     static volatil

NodeJS, Web-Express, and TypeScript from scratch

Over the past year I've been spending my time contracting for a company in Norway. Now that project is completed it is time for me to start playing again, so I thought I'd pick up an old Node Express project. This time I intend to use TypeScript instead of Javascript. I'd also like to write unit tests and dependency injection - both are something I'm very familiar with in the C# world, but not in Node. I'm going to use this blog to record what I did; I will undoubtedly revisit some of these posts and make changes as I learn. In this first blog I intend to cover how to get up and running with Node, Express, and WebStorm (optional) from a fresh installation of Ubuntu Linux. The first thing we need to do is use apt-get to install Node. sudo apt-get install nodejs I've noticed that some Linux apps will look for a command "node" and others will look for "nodejs", so after installing I want to make an alias so that both commands

[Solved] MVCApplication Parser Error

I have this problem because I have to develop with VS running as administrator in order to use Local IIS hosting. When files are added (or generated by compiling) I think VS was setting the owner as Administrator, which IIS then cannot read. Start a command prompt as Administrator and type in the following icacls c : \devpath\yourwebsite / grant everyone :( OI )( CI ) F / T

Watching a single property in an array in AngularJS

A typescript example that converts the array's property into a single string that can be watched. $scope . $watch ( () => this . someArray . map ( x => x . selected ? "1" : "0" ). join ( "" ), ( newValue , oldValue , scope ) => this . onSelectionChanged ( this . getSelectedItems ()));

Getting an AngularJS directive to call back a method on its parent's controller

Here is a TypeScript example of how to call back a method on the controller from an embedded directive. The most important thing to note is that the directive's parameter name for your callback uses a & when defined, and when calling that callback you should not use positional parameters but instead use an object with properties having the names of the parameters in the target. Register the directive when you create your app module: module MyApp { var app : angular . IModule = angular . module ( "MyApp" ); MyApp . Directives . FileUploader . register ( app ); } The registration code is as follows: module MyApp . Directives . FileUploader { class FileUploaderDirective implements angular . IDirective { public restrict : string = "E" ; public templateUrl : string = "/app/Directives/FileUploader/FileUploaderDirective.html" ; //IMPORTANT - Use & to identify this as a method reference

AngularJs - binding HTML

The directive ng-bind will escape HTML to avoid data acting maliciously. If you want to output html you need to use ng-bind-html <div ng-bind-html="someHtmlBody"/> The important step to getting this working is to ensure the script angular-sanitize.js is referenced on your page, and it is specified as a dependency when creating a module.... var app = angular.module("MyApp", ["ngSanitize", "OtherDependencies"]);

AngularJS routes with ASP MVC Forms authentication

The ASP MVC app I am working on uses forms authentication with a timeout. This means that when the session has timed out and the user clicks refresh they get redirected to a login page, and after that they get directed back to the original page without the deep-linked client-side # part of the url.  The solution to this is as follows: The first thing to do is to have the ASP MVC server side capture any URLs that should related to your client-side angular routing and return the single-page app HTML. When registering your ASP MVC routes add the following rule routes . MapRoute ( name : "Angular" , url : "x/{*clientPath}" , Where the "x/" is the base part of your client app, of course you can do without the "x" in the URL if your entire app is a single-page angular app, in which case you will need to add a preceding rule to render your ASP MVC server side account-login page. Then in your Angular app make
