[Unity3D] #DEVELOPMENT_BUILD not working in PreBuild Script IPreprocessBuildWithReport

I was trying to get some logic to work in a PreBuild script whether the build is a development build or not using the define symbol #DEVELOPMENT_BUILD. It works in regular scripts, but apparently it doesn't work for PreBuild scripts because the symbol won't be defined until the build actually starts. So the #DEVELOPMENT_BUILD never actually hits even though you have "Development Build" checked in the Build Settings.

To check whether or not your build is a development build use:

var isDev = (report.summary.options & BuildOptions.Development) != 0;

In the PreBuild script it would look like this:

public void OnPreprocessBuild(BuildReport report)
{
   var isDev = (report.summary.options & BuildOptions.Development) != 0;

   if (isDev) {
    // Is development build
   } else {
    // Normal build
   }
}

[FIX] Unity3D Cloud Build Missing Sprites

I was making a build the other day using Cloud Build, but some of the sprites were missing for some reason. Everything looked fine on a local build though.

Turns out I had the sprites in a folder called "Library" in my Unity Project and Cloud Build ignores or strips out content from that folder. The sprites showed up again in the cloud build after renaming the folder.

[How] Bypass Unity3D's "Hold on" Import on Launch

Sometimes it takes forever for Unity to launch. Especially when you have a lot or large assets. For some of our projects it could take hours for Unity to actually launch the editor. It's super annoying and you can't do anything else in the meantime. But there is a way to skip all that in the newer versions of Unity.

If you're having this problem, start a new project with a particular Unity version so you can actually get into the editor. Then go to Edit > Preferences > General and UNCHECK "Compress Assets on Import". Now close the project and open your actual project and it should launch way faster!

[HOW] Find Old Firebase SDK Versions for Unity3D

The SDK link on the Getting Started with Firebase page automatically downloads the latest Firebase SDK. Quite annoying if you're looking for an older version if you want to re-import an older SDK for your project for example. Luckily there's a way to download the older versions. Just enter the version number that you want in this link  https://dl.google.com/firebase/sdk/unity/firebase_unity_sdk_{Version number}.zip.

For example, if you're looking for version 6.0.0, the download link would be https://dl.google.com/firebase/sdk/unity/firebase_unity_sdk_6.0.0.zip. That's it!

[FIX] Unity3D - Android - Unable to List Target Platforms

A few months ago I was trying to create an Android build for one of my Unity3D projects which used to be primarily for iOS. When trying to create a build, Unity showed this error:

[FIX] Unity3D - Android Keyboard White Text on White Background

The Android Keyboard text appears to be white on a white background for some reason (at least in Unity 5.5.1f1 and below) when testing on an Android device. So there's no way for the user to tell what the current input text is unless they highlight it. Not sure if it's an actual bug on Unity's end or if there's a styling conflict caused by multiple Android manifests. Luckily, there's a quick way to fix this.Read more

[Unity3D] Copy to Clipboard Script for iOS & Android

I was looking for a way to copy a piece of text to the clipboard on iOS and Android devices the other day. There are ways to do it for Windows and Mac computers, but getting that to work for mobile devices seemed a bit trickier. There were some solutions on the Unity3D Community forums, but they were always either for iOS OR Android and required additional extra steps to make it actually work. Luckily, I found this handy script by Wataru Sanuki which handles cross platform copy to clipboard in a single class.Read more

Useful Unity3D Stuff

I work quite extensively with Unity3D and over these past few years I've come across a ton of problems. Usually I managed to find a solution for them, but I don't always keep a record of those solutions. If I do, it ends up being a bookmark or a note somewhere. So I decided to make a post to keep track of useful stuff for Unity3D. I can finally clean up my mess! And who knows. It might help other people as well.
