Ryan, We NEED a part 2 drastically! I have been playing with the blueprint but am having issues returning the player character to the main landscape!

@elcid2651 8 ай бұрын

I implemented something similar to this using the Pawn class in an earlier version of UE. To get the camera and movement working like in standard "flat" gravity, I needed to derive the movement vector by making a Right vector from the camera's right and the Actor's Up vector, and a Forward vector from the camera's forward and the Actor's Up, and then apply them as 2D input into the movement component. I think the only drawback was that I had to limit the camera so it never goes quite to 90 degrees above or beyond the player, but aside from that, it was a pretty solid foundation for the rest of the movement logic.

Hello, I designed a similar system too on my project. Can you share blueprint screenshots if possible?

@elcid2651 7 ай бұрын

@@kkayaoglu I don't know how to share screenshots on KZbin unfortunately, and it's a bit of a mess anyway (unfinished project). I can more or less describe it to you though: For the right movement vector I'm taking the forward vector from a rotator 'Make Rot from ZX' in which the Z value is 'Get Up Vector from Actor' and the X Value is the forward vector from a 'Make Rotation from X Vector' from the Camera's right vector. NOTE: I'm not actually using the camera's vectors, because I found these unreliable, so instead I attached Arrow components to the camera, and used their X vectors to get the camera's Right and Forward vector. The forward movement vector is pretty much the same thing, except I used the camera's forward vector: So I took the Forward vector from a rotator 'Make Rot ZX' in which the Z value is 'Get Up Vector from Actor' and the X Value is the forward vector from 'Make Rotation from X Vector' from the Camera's forward vector (the forward vector from the Arrow component attached to the camera). As mentioned before, it doesn't hold up if the camera goes above 90 degrees, so I had a function to limit camera movement to just below that, and also I ran into issues whenever I enabled camera lag, though that may have been down to how I implemented my combat system. Anyway, hope that helps. If you know a way to upload screenshots, let me know!

Great video. I'd be interetsed in inverse gravity. Like in a space wheel, cylinder or ring world.

Camera --- get world rotation --- break rotator(z) --- (z)make rotator --- get forward vector / get right vector

@CruelCrusader90 6 ай бұрын

arnt you just splitting the pins and recombining them? >.> break rotator doesn't remove the previous values, it just splits the pins. >.> edit: you can right click the "Get World Rotation" output pin and click split struct pins.

Mindblowing tutorial. Also, thank you for explaining every decision in mind! This is so helpful. Quick question: Would it be possible to assign this to a niagara particle mesh sys and have the character gravity walking on a bunch of spheres randomly separated?

hey how can I make the camera movement to align with the player gravity direction?

@BlackskyRadio-x9s 20 күн бұрын

Hey Ryan I read a few years ago that they used the surface normal to align the player character in a negative z to walk on irregular meshes.

@kiomy_music Ай бұрын

Looks cool but there is no way of rotating the camera based on the player rotation. I've been trying to figure our a way a few days.

How do you return the gravity field to normal or down directional after jumping from the planetoids to a flat plain?

@zanesnep 3 ай бұрын

Please make a follow up! I'm still learning how to do blueprints, and I really want to know how to make the camera rotate relative to the player's rotation/position. Oh, and if you wanted to make other things like objects, vehicles, and other characters react to the gravity field as well, that would be sick! Thank you so much, man!

You said there's another video after this one that you can do with other shapes than spheres where is that by chance? If there's not a video than can you by chance tell me how to use a cube or other shape than a sphere?

The gravity direction set is no longer in ue5, what should I use?

@Foolsjoker 4 ай бұрын

This does not work for first person view. The camera doesn't rotate with the mesh (at least for me it doesn't), which attaches backwards to the sphere. As seen in the video. Leaving the player looking down their own neck or head.

How can I implement this into a large world with multiple planets? I tried using it but you have to collide with the planet for it to work the best. But if you say go to the bottom of the planet then you just fall away from the planet unless you start off touching the planet. How can I fix this?

@souhaibbenchaker4824 8 ай бұрын

For the movement with the camera, you can project the right/forward vector of the camera on to a plan with a normal that is negative of the gravity direction then normalize it. Also is there a way to use this new node with something other than a pawn? For example a mesh that has simulate physics enabled? That would be soo cool!

@xiaoyuwang9940 7 ай бұрын

Hello, I followed your video and have a question about the Event ActorEndOverlap section. Why do we first check if the actor's class belongs to BP_GravityField, and then use the Cast Failed pin from the Cast To BP_GravityField node? Aren't both of these steps for clearing the Current Gravity Field when the overlapping actor is not a gravity field? Thank you so much!

Hello! Someone can say me, please, how i can disable gravity? I know about "gravity scale" in character movement settings, but it's not good because 0,0 gravity scale also disable collision of my character. I'm just want that my character will move on z-axis (up/down) and not fall because gravity. I know about flying mode, but because gravity my character fall. Flying mode good work for jump, but not clear fly. I want move my character up on z-axis and that he will stay on location when stopped movement. Thanks

@thijsbouma8818 6 ай бұрын

i did get this to work, but when i go into multiplayer one of the characters(the server displayed on the client side) movements is broken. it only is when i set the gravity other than 0,0,-1. is there something i'm doing wrong?

@JonSkov-DK 4 ай бұрын

Yeah, it seems like only the location of the capsule component is replicated as default, but not the rotation - I'm stuck on the same issue. Edit: You can check the Ignore Base Rotation in the Character Movement Component. Unfortunately though this seems to work, it generates other issues.

@thijsbouma8818 4 ай бұрын

@JonSkov-DK I don't think we experience the same error. The rotation is replicated correctly and on the server side the movement of the cliënt works pretty good, but if I play as the server or a second cliënt, then the movement is very jittery and the character seems to be falling and landing continuesly. I haven't found a solution yet.

@mlaffon 2 ай бұрын

What would be a good way of doing this based off the character instead of using a gravity field so you don't have to add a field for every object used for the player? Still awesome video thank you!

Hey Ryan I'd love to see this developed as a series, I have a game idea for this, and I just deleted tons of practice junk projects to start fresh, with what I've learned, I was wondering though would putting the cast node into the tick, slow the system and could you optimize that with a interface and a timer? Also you look exactly like a guy that I'm enthralled with his knowledge and an old friend that loves me lol jk he doesn't talk to me anymore, but he taught me before we had tons of tutorials everything he knew except the this is the content so it freed me for my own ideas. I just spammed the net with my idea for ue6 too, starting with Tim, and I'm wondering what you're up too now that you've solodeved mimic, would you be willing to take a look at my idea, as a possible future project? And help out by developing the training content for a possible new engine. I came up with an idea to get content to the public with reduced file sizes by using the media assets as like a tv broadcast for godot, as a web viewer for the engine that stores the content on a host machine, that way the player doesn't have to download a massive data file to play online and the way I'm thinking it'd work is that you'd just stream the media file to the webviewer with out terrain or anything and the only thing the player would receive would be the abstract object code that runs the player on thier end and sends tiny code data through the network while recieving the pixel streamed high res art without a massive file size on the users local pc, cause I saw the internet bitching about massive file sizes. Could that work?

i think you can get this result by multiplying the field vector by -1. this way instead of pulling you in it would send you out. im new to UE and havnt tested it, but that's my assumption. >.>

Did you ever figure this out? Is there some sort of decay function to the gravity value from old to new? Would lerp work?
