[Unity C#] First Person Controller (E02: Fixing Diagonal Movement Speed)

[@pixelart0124]

Thank you for this simple and working solution! I wanna add that you can put movementSpeed in place of the 1.0f inside the clamp. Same result, simpler code.

[@NECjAR]

You are very good in code and smart, man.

[@adhochero6619]

thanks. i was using .normalized before, but that would make it always 1 which means you couldnt move forward slowly like if joystick was only pushed halfway forward. but the clamp works great

[@MoonLiteNite]

diagonal walking as was a "trick" in so many games of the 90s as a way to move faster,.. still see it working in some games to this day :D

[@raptorswire7212]

I believe you can also normalize your vector with something like: direction = direction.normalized;

[@user-og6hl6lv7p]

direction.Normalize();

[@carlabalos3884]

But what happens is your controller moves a bit after releasing the movement button.

[@avenemfilmes7101]

using .normalized or .Normalize() will invalidate the acceleration of your character (since its gonna be 1, 0 or -1)

[@avenemfilmes7101]

@@carlabalos3884 if you are using the GetAxis, it will do, but if you are using normalize add GetAxisRaw

Fantastic FREE lessons on Player/Character movement and allready so much better the the Uniity standardAssterFPSController.... haha !

[@scottalexander_]

Cyborg PhotoshopVideos agreed!

[@St4rdog]

For 'Move' you also have to multiply by Time.deltaTime after movementSpeed.

i totally get what your talking about

Thanks so much lol, This is super useful there is a little more you could explain to use it in a more complex way because some people might not find out although its not really ur job so oh well lol.

[@deadlysteel300]

Love this

[@vincentj2024]

Love the tutorials so far! I do have one question though. I have noticed while jumping you can only jump in a specific direction. How would you go about moving while in the air(during the jump)? Thanks

[@AcaciaDeveloper]

Very good question! This is how I'd probably solve this problem: While the character controller is in the air, the SimpleMove function will cease to apply any new force until the character controller is grounded again, so when the player leaves the ground, you'll want to instruct your program to switch from using SimpleMove to Move since Move is able to operate in mid-air. As you can imagine, we pass the same Vector3 value into the Move function as we did the SimpleMove function, but we append an extra multiplication by Time.deltaTime since (unlike the SimpleMove function) the Move function is framerate dependant: charController.Move(Vector3.ClampMagnitude(forwardMovement + rightMovement, 1.0f) * movementSpeed * Time.deltaTime); Ideally, within context of the code in this video series, the value passed into this function could, and probably should be combined with the function call that we make to Move within the JumpEvent() coroutine to push the player into the air (It's recommended that you only make one call to Move and SimpleMove per-frame). One thing you'll want to execute ONCE at the beginning of every jump is this: SimpleMove(Vector3.zero); This makes sure to zero out any forces applied by SimpleMove prior to the jump. This is what we want, since the Move function will take over from SimpleMove as soon as the player leaves the ground. The example code snippets above are only there to help you understand, and the implementation is probably a bit more complex, but I hope this helps point you in the right direction.

That was exactly what I was looking for, thanks!

[@RetroAnt3]

Great help. Thank you

[@pixelscholar]

Worked like a charm. At its heart, we're essentially tweaking a matrix transform with this little addition to the code right?

[@AcaciaDeveloper]

This portion of the code does not tweak anything like that directly. I'm simply clamping the x, y and z elements of a standard Vector3 object to 1, and it has nothing to do with any matrix transformations at this point. It's not until the vector is passed through into the SimpleMove function that its value has any effect on the game object's position, and thus, the values stored within its underlying matrix.

[@null987]

First off all, this is a great solution for the problem previously I had just used an if statement but I'll change up my code to include this solution. Q: I noticed that when going down a slope my character controller bounces instead of moving along the slope, I realize that the problem is that the character is moving faster in the x,z plane than the velocity at which he is falling, so far I've got a solution but it only works on stairs do you by any chance know how I can solve this problem in a more elegant way than just applying a downward force when the player is on stairs since that method feels like brute forcing my way through the problem instead of solving it and it doesn't even work on general terrain but only on pre-made stairs and ramps? PS: Love your work, and sorry for the long question!

[@AcaciaDeveloper]

Hello, thanks for the complements and I don't mind long questions. This is in fact a topic planned for the next video in this series. My system works by shooting a ray from the player's position downward. If the surface's normal below (that the ray hits) is not equal to Vector3.up or (0,1,0), the surface is sloped and thus (similarly to your solution) applies an additional downward force. I've tested this on a terrain with the jumping mechanic, and it seems to work well without any issues (to my knowledge), so my solution may be more beneficial to you. I have looked for more elegant solutions in the Unity forums and other sites, but most seem to point toward this method of adding more force. The only other way (I can think of) is not to use the physics system at all. E.g you could shoot a ray directly downward from the player, get the position of the hit point on the floor, and set the player's position directly to a point that is n number of units higher on the Y axis than this point on the floor (where n is probably half the height of the character controller). This method has been known to be a bit jittery though which would probably prompt additional function calls for lerping etc. Personally, I'd choose the method of applying extra force within the physics system, since it seems to fix everything in one simple function call. Hope this helps anyway.

[@null987]

Thank you very much for the answer, I have also seen raycast being used in unity forums and I believe that is the best solution available right now! I'll do some research on it and I'll make sure to watch your video on the subject as soon as it comes out!

[@stephencooper8710]

Great tutorial I want to be able to move up and down but not a jump effect so that if I move up I stay at that position but I can only move down to the ground position at the lowest point is this possible?

[@Mark-vt7pl]

Great tutorial. How would you implement an inverted y axis for the camera?

[@Mark-vt7pl]

Nvm i figured it out, you just change the transform.Rotate(Vector3.left * mouseY); to transform.Rotate(Vector3.right * mouseY); :D
