In this video I demonstrate how to create a top-down character controller movement script in Unity which take into account the rotation offset of the main camera. This video also demonstrates how to make a game object rotate towards the mouse cursor on the screen, as is commonly seen in top down shooters. Learn some basic vector and rotation operations along with a simple and practical physics raycast example in Unity.
Technology Used
Unity 3D Engine 2019.3
Git

.Net Scripting in C#
Everything shown in the video can be downloaded from my Github repository so you can follow along, or reference my approach to creating a top down character controller component.

This video is great. It really helped me with creating an isometric character controller. You not only covered the movements but also smoothing out things like rotation and point and click movement. Hope to see more great tutorials from you in the future!

Awesome video! I'm super new to programming and Unity so this gives me great insight! One thing to not overlook is the value of talking to yourself or somebody when problem solving. It really helps walk you through the process thoroughly.

Amazing tutorial! Movement is one of the most important things in every game and a lot of people give it for granted, but you need to fine tune it until it feels great. Thanks for this video!

Agreed! The standard assets pack has great character controllers you can use but it's important to understand how they work vector math can be hard sometimes

For everyone having troubles controlling there movement, for me it helped to use this code in the Update funtion: float moveSpeed = 10; //Define the speed at which the object moves. float horizontalInput = Input.GetAxis("Horizontal"); //Get the value of the Horizontal input axis. float verticalInput = Input.GetAxis("Vertical"); //Get the value of the Vertical input axis. transform.Translate(new Vector3(horizontalInput, verticalInput, 0) * moveSpeed * Time.deltaTime); //Move the object to XYZ coordinates defined as horizontalInput, 0, and verticalInput respectively.

Fantastic tutorial, clear, concise and you even showed a nice toggle for the controls! One thing I would add though (and kind of important) is that on line 62, the targetVector doesn't get normalized, so you'll move quicker in diagonal directions if you push horizontal and vertical keys simultaneously. So I would just add in between line 62 and 63: targetVector = Vector3.Normalize(targetVector); Referencing time stamp around 20:00.

If anyone want player to rotate smoothly when aiming ,instead of using transform.LookAt(target) try using quaternion.slerp : Vector3 targetVector = new(hit.point.x, transform.position.y, hit.point.z); Quaternion targetRotation = Quaternion.LookRotation(targetVector - transform.position); transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);

@zidlik6461 3 жыл бұрын

Hello, is there a way how to set up that the forward direction will be always where the mouse points? (for example when the mouse is in the left top corner and you hit "w", the character starts moving to the top left corner). Or instead of mouse second (right) joystick on gamepad?

@SuperEckoO 4 жыл бұрын

Hi, thank you for the wonderful tutorial. I would just like to add something about the diagonal movement, now it seems to be too fast. I've looked around a bit and if you add InputVector = new Vector2(h, v).normalized; it seems to fix it.

This video was absolutely perfect! Only thing I need to do now is to have my camera follow my player if he moves a certain distance away! I did have a question though....Would it be better (technically) to have our movement in FixedUpdate() instead of calling it in Update()?

@keeganbrakhage7835 2 жыл бұрын

sorry im inexperienced, I'm just wondering why do we make an input handler? would it not be more simple to get the input in the same script we move in so we don't have to do all this converting? my best guess is that we have one spot that we can edit or stop all input from easily if we need to, is that correct?

Quaternion?! I gave up all hope in learning c#... Prior to today, if you would have asked me what Quaternions were, I would have said it was a race in Mass Effect. Jokes aside, why is my X movement acceleration slower than my Y movement acceleration? in other words, A and D movement accelerates slower than W and S? any help would be much appreciated.

Cool how difficult is it to have speed affected by the terrain slope?

@brokenknightsgames7966 4 жыл бұрын

This can be done using the built in physics engine, where instead of moving the character by sliding the transform, you would apply a force vector to the character's attached rigidbody component and let the physics engine do the work

How would I go on and make the camera follow the player instead of it being static? When I attach it to the player the screen spins uncontrollably... Thanks in advance and great tutorial!

@humblebee3112 3 жыл бұрын

You can simply add a script to the camera that sets its position to be that of the players, or you can use cinemachine which does that plus a lot more for you, you would just have to learn to use cinemachine as with any tool. Hope that helps :D also cinemachine is free and awesome so I recommend!

How would i make this so when i press for instance W to move forward it actually moves towards the mouse and not in a static FORWARD?

@brokenknightsgames7966 3 жыл бұрын

Check out the RotateTowardsMouseVector method in my github repo. Basically screen to word raycast from the mouse arrow to get a point in world space and then rotate your character to face that point as the character is moves forward. github.com/Srfigie/Unity-3d-TopDownMovement/blob/Minimap/Assets/Scripts/TopDownCharacterMover.cs

Need help with: if(player is moving in world space z or -z direction){do other code here to move UI Icon direction of x direction as the player is being pushed in the x direction always and UI Icon must show this when player is facing in either z or -z world space ditection movement the icon either points right or left depending on the player z movement} The code inside the brackets is fine but the if( player is moving in z or -z world space) I can not figure out 3 weeks later.

Why you constantly uses the "var" variable? Is for to performance of the game?

@brokenknightsgames7966 3 жыл бұрын

var is a keyword in c# that let's you declare a variable without having to specify the type because it can be inferred. For example "var playervariable = new Player();" VS " Player playervariable = new Player(); "

@captainawesome2226 7 ай бұрын

I know this is an old clip but I'm pretty sure using transform.position = (whatever) to move an object instead of setting the rigidbody force or velocity will completely break colliders in your cardinal directions. Wouldn't recommend it.

@TheOnlyOwnedbyCow 2 жыл бұрын

This causes movement along the x and z values. It is easy enough to fix it to move along the x and y value, but when you try to turn your character, it will not turn properly anymore. How can I change this line to use this value instead? transform.rotation = Quaternion.RotateTowards(transform.rotation, rotation, rotateSpeed); var targetVector = new Vector3(playerInput.InputVector.x, playerInput.InputVector.y, 0); I only changed the line of code to affect the y value instead of z. Using it like this will actually cause the rotation on both the x and y values and not z. This matters because when you put unity in 2d mode, it aligns your screen to the x and y values, not to the x and z values. If I were to continue in unity 2d mode with this coding, absolutely every sprite would need to be rotated so that the camera could view it.

I did the exactly same thing even copied the script from the download, but i have like a bug that when i touch with my cursor a 3d object like the floor of my scene, my character like starts to spin and go crazy, and when my cursor isnt touching a 3d object the rotation doesnt work

This is great, but I'm still absolutely lost on how to revolve the camera around the player while using this. I've found out how to use the mouse to revolve the camera around an object but if I throw this on top of it the results are... unity crashing to say the least. lol

@dibaterman 3 жыл бұрын

Or rather, how to orbit the camera around the target player. I'm still messing with it though but w/e.

Cannot find 'InputHandler' on Visual Studio. I tried many things but didnt worked. All resources says should use InputActions, Should I ?

@SuujiNoKami 3 жыл бұрын

He is creating that with the first script. Nothing fancy you can simply use Input.GetAxis() too. The way he does is more logical. I suggest you to learn about classes in unity C# and dividing your script to pieces.
