I've been looking all over and tried numerous tutorials for a flight/space sim and yours was the best and most straightforward! So many of them are overly complicated but I appreciated your straightforward approach!
I actually came here just to see how you applied rotation for a physics based aircraft, as I had a ton of trouble correctly rotating my physics helicopter and I just couldn't figure it out. I never knew the "Negate Vector" node was a thing, and it instantly solved my issue of not being able to counteract the torque I applied to my helicopter. Thank you so much, you've helped me save hours of work!
Great video and was helpful, Now I am off to make a proper elevator and aileron system. Being a pilot it hurt to see you use the elevator as both but this works great to show us how to do it in the most simplest way :)
Thank you very much! After watching over 10 different videos, I finally found the one that helped me create exactly what I was looking for. However, there's just one issue I'm facing. When my ship collides with an object, it either bounces back too forcefully or gets stuck to the other object. Can you please assist me? I'm working on a 6DoF space shooter, and I'd like my ship to have less of a reaction upon collision.
Great video as always!! .. It was perfect, I needed to create some kind of Air control for a vehicle and this tutorial gave me the solution.. thanks!!! :D
your airplane should fall down when you are not accelerating. if you cannot accelerate you missed a step in the tutorial. check the nodes and variables again. have you put all the numbers in the lerp and clamp nodes?
Can you please explain how to set up a model in Blender for import with moving ailerons / flaps / props? Must it be set up as bones? Or a simple mesh with multiple parts and one connects them in UE? Or is there a predecessor video to this?
17:28 Here is the real issue while using UE4 physics on a plane/jet fight system. Honestly, I have encountered this problem two days ago, and I ended up solving this issue using "advanced" physics that I wrote to replace current Ue4 physics. Well, the main problem is that when you apply anything force/acceleration/torque related, even if you reset the force back to zero, or by applying a "elastic force" (which relatively works like a spring to basically "brings everything back when there is no input"), there always exists your biggest problem called moment of inertia. I think starting from 17:28 has well explained what I meant by. (e.g., your plane is flying backwards after force/acceleration was applied when turning to an opposite direction.... your velocity still exists and its gonna take a while to deaccelerate it to zero and regain speed in the current direction). End conclusion is that: if you wanted to fully enable UE4 physics, then you have to calculate/design a completely new physics system, including drag, gravity, lift, trust, and somewhat force/torque from rudder(s) is/are independently calculated other than from ailerons and elevators, (that says you have to differentiate the center of mass from the center of the acceleration, so your plane can actual balance itself), etc.,... In that case, you are technically recreating a DCS. Now another solution is to bypass the acceleration, using delta second multiplying acceleration variable then use it as the speed increment per delta second (e.g., the easiest form it tries to mimic is that x is equal to one half of x double dot times t square, if it x dot starts from zero) then to act on the forward vector in order to create the velocity, hence to mimic the acceleration. Which they all visually "behavior" the same, however, since now you have full control over velocity, you are very well bypassing the existence of moment of inertia caused by any force/acceleration/torque. And yes, in the ladder case, you are basically building a AC or Project Wingman... Hope that may help anyone who spent time reading my comments :)
I like this approach some. After watching and testing various flight tutorials, this offers a lot of options. Especially when combined with features from the others. However, I have found that "Set Bone Rotation by Name" , specifically in UE5 only works if the XYZ is in alignment with I am assuming root. For instance if you add this to a Aileron that is on a swept wing aircraft the rotation will realign the bone with the root direction and rotation is not in alignment with the swept wing. weird. Need to figure out how to rotate bone or socket first to axis of swept wing.
@@muller_digital yes/no. I did but I have lost all of those files. I have not done programming in a few weeks due to a disability. Time will tell if I can get back to it. But it is just a matter or accessing the bones in a different matter/orientation.
Idk what part I messed up to make my plane hate me, but after 3 attempts I can't get my plan to fly straight it just hard barrel rolls in every direction until it crashes into the ground.
Could be that your driver doesn't have it's collision set properly - make sure the collision preset is set to PhysicsActor, you have 'Enable Gravity' unchecked, and 'Simulate Physics' checked. Also your poseable mesh should have either no collision or be set to BlockAll. Let me know if that helps! :)
@@underscore00 Unfortunately nope. I am not 100% sure, I started from scratch in fps a couple times, and another time in 3rd. It's very weird, but yeah they were already set the way. I will try to see if I missed some part of the bp's something small like a similar named node or something.
@@Sweet._.Serenade Unfortunately, I gave up after hours of rewatching and trying different settings and different starting levels (flying,1st,3rd) As cool as it is, i couldn't get it sorted.
why is it so hard to find a good landing gear tutorial. i just cant get the colliders to retract with the gears while having physics on the plane. do i just replace the entire plane model?
Everything was running fine , until yesterday when I deleted the starter content . Now when I press play , the airplane is still in its place , its velocaity and orientation is not changing . The blueprints are exactly same , Even the prop rudder and other bone motions are happening perfectly , but the plane is not moving .
Hi, hope all is good. Well wanted to know that if i do this then i cant make a like taxi and take of moment for the aircraft as it falls through the terrain is their some method where i can like design real life physics mechanism for the aircraft taking off landing and taxing. Thank in advance
great video, my problem is that the geometry when creating the animation gets up the other way around in the game. The rudder is inverted, but the animation works
I've a Problem (of course, VERY GOOD TUT) ... my plane has a big delay of movements... Example: if I press to go left, plane&camera turn, ok, but vector direction velocity still remain the same and aftera lot of time reach the new plane direction. Every movement... How can I set an non-real movement, which follows my movements without lag, delay?
When I rotate Possable Mesh joints using Set Bone Rotation by Name it causes continuous motion blur on the moved part? I'm only call it once by the piece keeps moving what is even causing this?
I follow all your steps but when I play its go down to floor instantly and when I Left click to 100 the its go stable but not move left or right side. I check plan roll but not move left or right direction.
Probably easier if you just set the static mesh to "Hidden in game". Also, actual gravity is -980 so it's strange you made yours so high. Otherwise, it's a good start. Should make a follow-up video to handle collision.
Yeah the gravity figure is calculated based on the 'feel' of gameplay and not real-world physics. I wasn't making a realistic simulator :) It would be great to do a follow-up! Ive heard that implementing a good system for take-off and landing, as well as possession, would be a good idea... We'll see ;)
i know this is an old video but do you happen to know of a tutorial or something for making the ability to land and take off? struggling with that part
Hi, I found this tutorial interesting. Is there a video where you rig this? I'm trying to rig my model of a custom F22 and would like to know how jets are rigged for Unreal 4
Very helpful, though I don't suppose you'd know how to get the plane to naturally nose dive when not accelerating would you? At the moment it just plummets in the same direction it was already going and with the much larger aircraft I'm using it looks pretty odd. I've tried shifting the COM but that only seems to affect it when it's already on the ground.
It's been a while since I've had a look at this, but you could add a slight forward rotation along with the gravity calculation to make the plane behave a bit more realistically with gravity. I haven't tried that myself, but thanks for bringing this up! :)
great! I was just looking for a similar tutorial and you saved me! : D only one thing. I'm trying to make a shot with the sequencer to render it but, while the front helix is seen to be moving, the wings behind that should move based on the roll and as you get up / down, they stay still. makes the model static when it moves. how can I do? help me please :(
i really liked this tutorial, everything working fine but i dont know why my pawn starts to squirrl around like anything when i try to create my own values, even when adjusting just a little bit. soo a lot of respect to you for finding the right values to create this awesome physics..
Thanks for uploading the video! I'm curious: when you release throttle and turn, the plane keeps going to the direction it was going even though the "nose" isn't pointing to that direction anymore. I achieved the same effect with the setup I made, but...in my case, if I turn and start throttling again, it instantaneously cancels the velocity on the direction the plane was going and feeds a new velocity in the direction the nose is currently pointing rather than slowly fight to cancel the previous force applied and build up velocity in the new direction. I want to achieve something smooth and similar to reality. Any ideas?
What is the difference between add torque / force / impulse? I see that the torque makes sense for rotations, but if I want to make it move forward I can use all of those or not? (though impulse seems to be not good for ticks according to the editor hint)
Hello cool tutorial! I am having an issue I don' t know if maube is a bug my plane only can roll in left direction I have my inputs: Z(Roll left) C (Roll right) but plane always rolls on left side? Any Idea? Awesome tutorial!
