Kristyna HougaardNovember 27, Far North Entertainment is a Swedish studio co-owned by five friends from engineering studies. What makes the project stand out is the number of zombies chasing you. However, they quickly run into lots of performance issues when prototyping this idea. Spawning, despawning, updating, and animating all those zombies was a major bottleneck, even after the team tried implementing possible solutions like object pooling and animation instancing.
Will you do the same transformations of the same set of data over and over again? How much relevant data can you pack into a CPU cache line? If you are also looking to convert existing code, then identify how much garbage data you are filling the cache lines with.
The team came to understand that entities in Unity Component System are just lookup ids into streams of components. Components are just data, while the systems contain all logic and filter out entities with a certain component signature known as Archetypes.
Each Archetype is a table where each column is a component and each row is a unique entity. But general materials about data-oriented design were also extremely helpful to the team.
This blog post builds on this presentation and explains the specifics of their implementation of ECS, the C Job System, and the Burst Compiler in more detail. The Far North team has also kindly shared a lot of code examples from their project. Their first object-oriented approach was to make an abstraction of a ZombieView script which inherited a more general EntityView parent class.
It acts as a visual representation of the game model. Every ZombieView was responsible for handling its own translation and rotation interpolation in its Update function. This seems fine until you realize that every entity is allocated in a random place in memory. If you lay your data in neat continuous blocks, the CPU can cache a whole bunch of them at once.
Most CPUs today can get around or bits per cycle from a cache. The team decided to convert the enemies to DOTS with the hope to eliminate client-side performance bottlenecks. First in line was the Update function of the ZombieView. The team identified what parts of it should be separated into different systems, and what data would be needed. The first and most obvious thing was the interpolation of positions and rotations since the world of the game is a 2D grid.

I am new to Unity trying to make my first game a Third Person Shooter. It's been now more than a week that I've tried again and again to get my character moving using a rigidbody component and NOT the Character Controller or the simple transform. I have had about 30 web pages opened since a week browsing topics about it but I haven't found anything almost made me feel like I am trying to do something impossible lol So, I want to move my character just like in Splinter Cell Blacklist, and to have the camera with the crosshair controlled by the mouse if I shoot, the character would rotate if not facing the target and then shoot.
For the movement, if it is not possible with the rigidbody then I'll use one of the others, it's just that I love the real feeling that the rigidbody has. If there's even a tutorial that break it down to really understand, that would be great or just some code with comments I have a C background. My idea. If you want the real feel, you need the rigidbody.
Not the rigidbody. Learn more. Asked 3 years, 11 months ago. Active 1 year, 8 months ago. Viewed 7k times. Machavity Manu Manu 45 1 1 silver badge 8 8 bronze badges. I mainly do 2d Unity work so I dont know how much help I can be with your situation, but here is a really interesting video I found that I think will be able to help you out a bit.
Dont let yourself get down about it, its always hard at the start. I found that the longer I kept working at it not only did it get easier but it got way more fun!
JessyDoyle Thanks for your reply and yes I have watched a lot of his videos, he's really good! And it's actually because of that specific video that I want to go with a rigidbody ahah. JoeBlow Why, because it has a way different feeling for the end result I want, and just like on the video linked by Jessy Doyle, it explains what I have just said.
And from what I have read on Unity website, when you want to use physics in Unity, you rather want to do that in the FixedUpdate, and since for what I know so far, it's Unity that says so, I figured it's the right way.

A very simple third person controller including character movement- and camera script. It runs smoothly and the camerascript implements a method to compensate for walls and obstacles between camera and character positions.
Unity 3D First and Third Person View Tutorial
Setup: It is highly recommended to check out the included example scene, to get a grasp on what the scripts' public values should look like. Set up a scene with main camera and a player object with character controller remember to tag them as player and main camera if necessary. Set the layer of the player object to something like "Player Layer" this is important to have the camera ignore the player when trying to compensate for obstacles - alternatively you can go and change the layermask directly.
Assign the objects' transforms accordingly - PlayerMovement needs the camera's transform, CameraMovement needs the player's. This will add some easing to the camera movement, adding this functionality to the CameraMovement. Skip to content.

Have you ever asked: Why this camera is so strange to me? Well, I'm researching and building this repo to save your develop life! A: The Unity 3rd person camera is a little strange from the pattern in the commom gameplay. A: Yes, i'll be adding new features such as animation optimization, more options for the camera, etcs to the project while I have free time to spent on it.
Besides, fell free to improve it yourself. A: This is a free asset. Use and abuse it but give the right credits. I'll be adding an donation option here, so you guys can help me. Skip to content.

Latest commit f Dec 29, Features Character rotation not-linked with camera rotation Always move to where the camera is point to, realtive to character rotation Some animations integrated with this system Know issues If you rotate the camera to max-value top or the max-value bottom something like the head or the foot of the character, it'll flip in a strange movement It ignores collision with some object's, leaving it inside that could cause some problems depending in the complexity of the object FAQ Q: Why should I use this instead of Unity model?
A: Not yet, but it cames with an functional player model with animation Q: It'll have further develop, such an option X or optimization in Y? Besides, fell free to improve it yourself Q: How many this cost?

The basics will cover first person view, third person view, and collision detection. As usual, my tutorials will be broken down into several sections.
The first section will cover what first person view is and how to achieve it using code. The second section will cover what third person view is and how to achieve it using code. The third and final section is all about collision detection in 3D. You can download the complete Unity project for this tutorial here. First person view is not as complicated as you might think. Rather, it is actually super simple.
The implications of this thought process simplifies everything as a designer and as a programmer. So, how do we begin to utilize this knowledge within Unity3D?
We could start by building a 3D scene and setting up the scene for testing. I think that would probably be best considering if we do too much for a basic course, things could get very confusing.
Here, we want to search for and download the Grid Prototype Materials asset. Now that the Thirdparty folder has been added to your project, go ahead and add the Scene and Scripts folder. Also create a C script called FirstPersonCamera. We can now move on to the scripting side. I have tried to do an extremely basic approach to scripting to allow the camera to move with the event of using the mouse and keyboard. Since we plan on attaching the script directly to the camera, we can use the this keyword or omit the this keyword and just write the transform.
Now, we can attach the script to the camera by dragging and dropping the first person script onto the camera in the Inspector Pane. Save the scene in the Scene folder under the name First Person. To do this, click File, Save Scene As. Now you can go ahead and run the scene.
Voila, you now have a scene where the player is the camera.Search Unity. Log in Create a Unity ID. Unity Forum. Forums Quick Links.
