QUESTION

Unity 3'nd Person Controller Camera Acting Weird

Asked 2022-Apr-08 at 23:22

I'm very new in Unity and Stackowerflow. If i did something wrong, please don't judge me ^^ I used Unity's TPS Controller asset for my game. In first, it worked very well. But then It broke. But i didn't do anything :( (i don't even touch scripts or prefabs). After that, i deleted asset and re-download it but it didnt work again. Here is one example from my broken scene and these are the codes from my controller. Thanks For Any Kind of Help.

I had the same problem too. I researched a lot of documents about that and finally, I solved this problem. The problem is not about your codes or events or smth else. The problem is related to Unity. I don't know the exact reason for the problem but you can solve it this way: First, go Edit > Project Settings and select Input System Package from the Left tab. And then, change the Update Method with Process Events In Dynamic Update. And that's all! Dynamic update means the usual Update method that you see in the scripts void Update().

Install o3de

This repository uses Git LFS for storing large binary files. Verify you have Git LFS installed by running the following command to print the version number. If Git LFS is not installed, download and run the installer from: https://git-lfs.github.com/.
For the latest details and system requirements, refer to System Requirements in the documentation.
Visual Studio 2019 16.9.2 minimum (All editions supported, including Community): https://visualstudio.microsoft.com/downloads/ Check System Requirements for other supported versions. Install the following workloads: Game Development with C++ MSVC v142 - VS 2019 C++ x64/x86 C++ 2019 redistributable update
CMake 3.20.5 minimum: https://cmake.org/download/#latest (Release Candidate versions are not supported)
Wwise audio SDK For the latest version requirements and setup instructions, refer to the Wwise Audio Engine Gem reference in the documentation.
To set up a project-centric source engine, complete the following steps. For other build options, refer to Setting up O3DE from GitHub in the documentation. For more details on the steps above, refer to Setting up O3DE from GitHub in the documentation.
Create a writable folder to cache downloadable third-party packages. You can also use this to store other redistributable SDKs.
Install the following redistributables: Visual Studio and VC++ redistributable can be installed to any location. CMake can be installed to any location, as long as it's available in the system path.
Configure the engine source into a solution using this command line, replacing <your build path>, <your source path>, and <3rdParty package path> with the paths you've created: cmake -B <your build path> -S <your source path> -G "Visual Studio 16" -DLY_3RDPARTY_PATH=<3rdParty package path> Example: cmake -B C:\o3de\build\windows -S C:\o3de -G "Visual Studio 16" -DLY_3RDPARTY_PATH=C:\o3de-packages Note: Do not use trailing slashes for the <3rdParty package path>.
Alternatively, you can do this through the CMake GUI: Start cmake-gui.exe. Select the local path of the repo under "Where is the source code". Select a path where to build binaries under "Where to build the binaries". Click Add Entry and add a cache entry for the <3rdParty package path> folder you created, using the following values: Name: LY_3RDPARTY_PATH Type: STRING Value: <3rdParty package path> Click Configure. Wait for the key values to populate. Update or add any additional fields that are needed for your project. Click Generate.
Register the engine with this command: scripts\o3de.bat register --this-engine
The configuration of the solution is complete. You are now ready to create a project and build the engine.
From the O3DE repo folder, set up a new project using the o3de create-project command. Configure a solution for your project. Note: Do not use trailing slashes for the <3rdParty cache path>.
From the O3DE repo folder, set up a new project using the o3de create-project command. scripts\o3de.bat create-project --project-path <your new project path>
Configure a solution for your project. cmake -B <your project build path> -S <your new project source path> -G "Visual Studio 16" Example: cmake -B C:\my-project\build\windows -S C:\my-project -G "Visual Studio 16" Note: Do not use trailing slashes for the <3rdParty cache path>.
Build the project, Asset Processor, and Editor to binaries by running this command inside your project: cmake --build <your project build path> --target <New Project Name>.GameLauncher Editor --config profile -- /m Note: Your project name used in the build target is the same as the directory name of your project.
