Drive Your Boat - Boat Vehicle Tutorial for Unreal Engine 5.3 

Hey thanks for watching, at some point I hope I can work less and do more of this. I like the idea of applying wind mechanics!

100%, I'd probably use tick event. Just check that the boat's 'get actor rotation' equals the player's 'get control rotation', if false then add torque on the smaller angle until it does.

Yeah play with the buoyancy component settings and pontoon locations. Angular dampening in particular will make it resist rotation. The character moving is really odd since it's attached to the boat right? Maybe using a camera and switching the players view point instead is an option. Perhaps your movement is still triggering too, make sure the boat controls cancel out walking input.

Should be fine as is, make the construction script set the mesh to a variable and right click on the blueprint to make children of the class. Expose all the variables like speed, turn rate, etc.

@@peanut_games Thank you for the quick reply, i will give it a try. :)

Should be possible to dynamically set buoyancy force so it floats in place/sinks based on inputs.

@@peanut_games I can't seem to find any functions available to change these settings at runtime unfortunately :/ i.gyazo.com/558b9b31a6f6419a088969db232adcfd.png

I see another comment in youtube studio that isn't showing up here and never notified me... looks like you'll have to use set mass scale on the mesh

@@peanut_games youtube wont even show my own comments being replied to xD thanks for getting back to me

Personally my highest interest would be restoring physics. So I'd suggest either manually creating a simple collision that works or simply disable collision with the player on the simulating mesh and parent another invisible mesh with complex collision to the simulating mesh. I just tested it and it works. This method of course removes interaction between the simulating simple mesh and the player which means jumping and moving will not tip the boat at all, but this is probably desirable for a large boat as no inconsequential calculations are happening. Hacky but good results.

Yes leaving many movements to physics is a great opportunity instead of making them in code. I've tried manually creating simple collisions but they are very rough and the torpedoboat has masts etc, making the player walk 10 meters in the air. My buoyancy is all over the place with the torpedoboat mesh I don't know why. With the box mesh it works well. I was thinking of something like making the simulated box mesh invisible, then add my torpedoboat as a visible but not simulated mesh with complex collisions as simple for the player to walk on. As the box will be comparatively small inside the boat, the player collisons with it would not matter, even they do i guess i can simply disable them. You wrote "parent another invisible mesh with complex collision to the simulating mesh" which I didnt be able to understand exactly what you mean.@@peanut_games

@@endtasid I basically said what you said there, attach the complex collision to another mesh with buoyancy. Yeah you could just use a big invisible cube/cylinder for floating and stick the actual boat to that.

@@peanut_games thank you very much.

I made it, the big unsimulated boat now floats on the water thanks to the buoyancy of the little cube inside. I've changed its collisons to block all and use complex collisions as simple but still the first person just walls down thru the mesh. Still trying to figure out why.@@peanut_games

It should just toggle collision on the actor. Maybe try adding a 'Set Collision Profile Name' node with your character capsule's default collision profile on exit. Detach from Actor first.

@@peanut_games :D thank you!! i was finally able to solve it that way. i will name my son Peanut in your honor my brother T.T

​@@Parsifal308 I would expect nothing less

Mine did that naturally, depending on the mesh you may have to play with the weight and set the physical material to have more friction... the buoyancy component also has a function "Is In Water" so you could just pass movement through that condition

Probably just due to physics settings. In my case the force applied was almost entirely zeroed on land due to friction. Play with the mass of the mesh and force values.

make sure you're adding the input mapping context and that its priority is higher than your main

​@@peanut_games now it only works the steer (a+d) not the force (w+s) + the camera makes a zoom

First just make sure the root component absolutely is the static mesh and that "Replicates" and "Replicate Movement" are ticked. Does it float normally for the host?

@peanut_games everything works like planned in the editor, host and client side. Just when I package it things are different. If I delete the box collision used to control the ship, then the boat floats in the packaged game, but of course isn't driveable

@@-JimRice- yeah box collision has to be parent of staticmesh -- staticmesh has to be root. You can drag them around

​@@peanut_gamesgotcha, I believe all my parents are correct. Could it be a 5.3 bug?

@@-JimRice- I already have the project so I'll build and see if it works. Are you building in shipping or development?

that sounds really bizarre lol, are you perhaps attaching the character mesh instead of the capsule?

@@peanut_games I dont know, maybe 🤔 was so tired when I made it, but seems like it since it's not the camera, I pressed F8 to eject and I saw my dude was all leaning to the left 🤷🏼‍♂️

@@peanut_games I just did follow your setup, using the third person template.. I have it exactly Like you.. I have no idea why this is like this

@@peanut_games When I start my game rotation x y is 0,0,0.. When I enter boat it changes

@@peanut_games I managed to fix it by set Actor transform at the end of remove mapping context (when detatch)... The issue wich remains is that my player as taking rotation from the boat , so when I drive forward he starts to lean more forward overtime ? .. Ideas?
