Using thumbstick locomotion with the standard VR template - Unreal Engine 4 Tutorial

This step-by-step tutorial shows how to implement thumbstick (aka gamepad or joystick) locomotion as an alternative to teleportation in the standard VR template.
Two variations are shown:
1. Direction of locomotion following the HMD orientation
2. Direction of locomotion independent from the HMD orientation
In addition the VR Pawn is modified to add a collision capsule so it cannot go through other objects and walls.
*NOTE*: To keep it simple, this implementation is for a seated/in-place experience. Rotations will be inaccurate if you use it for a room-scale experience and start moving around IRL. This can be fixed implementing a roto-translation of the VR origin so the camera parented to it pivots around its vertical axis as expected. I may cover this in a future tutorial if anyone is interested.

I have finish the tutorial but the locomotion is very lazy i want to upgrade the speed , do you know how i can do that

@marcoghislanzoni 4 года назад

Take the output of the Y axis event (and X axis as well) and pre-multiply it by a float factor (say 2.0 or 3.0) before multiplying it by the Forward / Right vector. See at 5:00. That will make all your movements faster.

@chrisgo 4 года назад

Thanks for this ... I just needed the AddActorWorldRotation bit so I can turn with my joystick but now do you make it so I can turn non linear/not continuous, as it makes some people feel sick in VR turning like this .... so how to turn in sequential moves same as you do in the occult home please?

@marcoghislanzoni 4 года назад

This is called snap rotation. You can achieve it by adding a large rotation angle, say 30 or 45 degrees, to each movement and subsequent release of the thumbstick. What you don't want is to keep rotation if the thumbstick is held to the side. It's pretty easy to realise using a Gate in Unreal.

@noxix7641 5 лет назад

How would one change the speed that it turns or goes forward. Ex: Using trigger axis for forward movement, further one pulls the trigger the faster they go; and how would one adjust the top speed?

@marcoghislanzoni 5 лет назад

When it comes to control inputs, there are two ways to access them: 1) via events, like we are doing here, 2) by value. You can fetch the value from the trigger and use it to multiply the thumbstick value and a float which represents the maximum speed. That will both give you a boost option and determine the top speed.

@marcoghislanzoni 5 лет назад

Adam Libby That happens because when you press the grip button it activates physics for the hands. Check your collision settings for the hand and the capsule. You can excluded physics actors from the capsule collision response. Or setup a custom collision response for both.

any explanation why my VRPawn keep going through wall and object but indeed collide with the pickup cube? did i miss any step?

Because your VR Pawn doesn't have a body and therefore cannot detect collisions with other meshes. Your VR hands however are set to collide with other physics actors, so they do. Have a look at my other tutorial about thumbstick movement for archiviz. That is closer to what you are looking for.

@BR14Nx 3 года назад

I see two issues with this method. First, the VROrigin is inheriting from the Capsule. Which means, if you walk in your room the capsule won't follow, but stay in place with the VROrigin. Secondly, if you rotate the actor then you won't rotate on place (where your HMD is), but around the Capsule/VROrigin which can cause motion sickness. Is that right? I used another method to solve the first problem, but I can't find a way to solve the second as well. My VROrigin isn't inheriting from the capsule and vice versa. Maybe someone else found a solution to rotate at the HMD location? I tried to rotate the camera node around itself, but nothing happens.

@marcoghislanzoni 3 года назад

True. This method does not support room scale. I have another tutorial on my channel about room scale snap turn. That’s what you are looking for.

@marcoghislanzoni 4 года назад

That is an input mapped within Project Settings --> Input. It has changed in the most recent versions and it may have a different name now. You can always define your own with that exact name and assign it to the right thumbstick X axis.

@MaxBrunnerArchitect 6 лет назад

very Nice Marco. It only works for flat surfaces though. Maybe you could expand the BP so you can walk stairs etc?

@marcoghislanzoni 6 лет назад

Indeed, that's a limitation of the Pawn class and the way the movement is implemented. If you need extra capabilities like going up-down stairs, slopes, etc. you are better off starting from the FPS template which uses the Character Movement Component. Or you can change the parent class of the MotionControllerPawn to Character so you inherited those capabilities. If you do so, you also need to change the movement nodes to Add Controller Yaw Input for the rotation and Add Movement Input for the right/left, forward/backward.

@marcoghislanzoni 6 лет назад

Just tried what I described above. Change the parent class of the MotionControllerPawn to Character, then replace the movement nodes with Add Controller Yaw Input and Add Movement Input. Add some stairs. You can walk up and down. Works like charm!

Few things to check: 1. That the input events are defined under Project Settings --> Inputs. 2. That they are producing input values (you can use Print String to check the Axis value). 3. That the input values are flowing all the way to Add World Offset.

@VRExperiences4All 3 года назад

Thank you very much for the tutorial. Things like that are what is needed to give impetus to development in VR. On the other hand, when the VR hands are inside the pawn capsule and we grab, the free movement gets out of control. It goes backwards or even rises in the Z axis. I am sure it is a problem of collisions with the VR hands. Does anyone know how to fix it?

I have this working extremely well thanks! But question, when I pick up items, (I'm on the quest 2 btw) with the default vr template. I can only move in one direction. If I grab something with my right hand, I can only move right. if I grab something with my left, I can only move left. And if I grab items in both hands, it freaks out. I've even flown. Any advice? I can't find anything in the blueprints that would make this happen.

@marcoghislanzoni 3 года назад

That is very likely due to collisions. In the standard VR template when making a fist the physics/collisions of the hand are activated. How are you grabbing your items?

@kjgrizzly11 3 года назад

@@marcoghislanzoni I'm grabbing them using the default VR template settings. Grab/Release Actors. Since you have said that I have noticed that if I am holding an object in front of me I can backwards. Or if it's to the left of me I can move right. The same holds true the other way as well. So you're right, its collision somewhere. I haven't found it yet. But This is a step in solving it.

@marcoghislanzoni 5 лет назад

This technique only works if you stand in place or are sitting, it is not a room scale setup. If you need a room scale setup, you need to have a different setup where the collision capsule follows the camera. Also the rotation needs to take place around the current position of the VR camera, which is equivalent to a roto-translation of the entire character. A bit too complicated to explain it here. If you need room scale, you may want to consider the VR Expansion Plugin by Mordentral.

is this game can turn left,right with vive normaly? or can turn by only thumbstick???

@marcoghislanzoni 6 лет назад

Do you mean if this method supports room-scale movements? Then the answer is no. You can still move room-scale, but the collision capsule will not follow you. That would require a different arrangement.

Hi Marco and thanks for your amazing videos they are really helpfull! If i may ask you a question, can you think of any reason why i dont have the "Input Axis ThumbRight_x and _y only the ThumbLeft as an option?

@marcoghislanzoni 5 лет назад

Μιχάλης Φουντουκλής you are welcome! Check under Project Settings --> Inputs. If it is not there, you can add the mapping yourself by adding an axis event and linking it to your Thumbstick input.

@kkarpoyzhs 5 лет назад

@@marcoghislanzoni Thank you for the reply! It was indeed a problem with my inputs! If i do not trouble you a lot, i managed to setup the right oculus touch into rotating correctly, but the left touch controller doesnt do anything. I have tried this both in my project, and a fresh new VR template project with your locomotion movement events in pawn. Only the Left one that controls the movement doesnt seem to work at all. The rotation is fine. Do you have any idea why this might be the case? I dont get any errors in compile

No worries, i am (apparently) braindead. I had forgot to connect the axis thumbLeft x and y to the world offset.... I am sorry to take up your time! :)

@thequazzman 5 лет назад

Hi, Marco. Thanks for making this. You're making my life a whole lot easier. An issue I'm having though is that I believe my default camera position is somewhere in front of the capsule collider as I can phase through some objects when moving forward for a bit but not moving sideways. When I rotate, I also seem to be rotating from a pivot point that is anchored somewhere else. I tried to do a Reset player position and orientation on start but I end up in the floor. Any suggestions for how to fix this?

@marcoghislanzoni 5 лет назад

Are you using a room scale setup? The rotation technique is not suitable for room scale. For the other issues, it is difficult to tell what is going on without seeing what is happening. You can contact me on Unreal Slackers (Discord) as vr_marco if you need more help.

@thequazzman 5 лет назад

@@marcoghislanzoni Hi again, Marco. Just as a follow up, I was able to fix my issues by simply changing the tracking origin of the hmd to eye level instead of floor and also using a ResetOrientationandPosition node on beginplay

Yes it will work properly. To move faster, just multiply the output of the move forward event by a float > 1.0.

Any tips on sprinting? Sprinting based on if the face is clicked in rather than being touched.

@marcoghislanzoni 6 лет назад

You can use a speed multiplier for that. It is normally set to 1.0, but gets set to 2.0 or 3.0 if the face is clicked or a sprint button is pressed. When the sprint button is released, you set it back to 1.0. This will achieve a sprint effect.

@landonshultz 6 лет назад

Thanks for the speedy reply! I figured it out. Have you thought about doing a crouching tutorial? Getting the players height, adjusting speed based on the height of the headset (60% lower than the player previously set height or so).

Devi moltiplicare il valore in uscita dall'evento di input per un float maggiore di 1. In questo modo amplifichi l'entita' del movimento.

@@gennaroscalia8213 Dipende da quale movimento vuoi amplificare. Se quello di spostamento avanti ed indietro devi moltiplicare il valore del rispettivo asse. Se sia avanti indietro che destra sinistra allora devi moltiplicare entrambi gli assi (separatamente anche se per lo stesso valore).

You need to connect the output of the controller input event (red box) to your print string so it shows which value it's being generated. Otherwise it will keep printing the default message.

That depends on how you built your level. In general it should work, otherwise you can always change the collision presets or even create a custom collision channel to handle your special situation.

Ok, understood. This technique is suited for a sitting/stand in place experience. If you want to be able to walk around IRL and have your collisions still work properly, you need to use a plugin which handles room-scale movements like the VR Expansion Plugin by Mordentral: forums.unrealengine.com/development-discussion/vr-ar-development/89050-vr-expansion-plugin

Ciao Marco, è possibile aggiungere un movimento di inerzia come se si fosse in assenza gravità? Grazie ancora

@marcoghislanzoni 5 лет назад

Si' e' possibile. Usa Finterp dall'output del motion controller thumbstick left X per settare l'entita' del movimento orizzontale. Se usi un tempo di interpolazione basso, ci mettera' un po' a partire ed altrettanto a fermarsi, simulando una sorta di drag iniziale ed inerzia finale.
