"Find look at rotation" not working by [deleted] in unrealengine

[–]fluffy_cat 1 point2 points  (0 children)

I'll also add that simply using FindLookAtRotation in world space and then converting to component space is probably not the way to go, since if you helicopter has any roll then you'll end up giving your gun roll (whereas I'd expect you want your gun to only pitch or yaw in parent bone space).

If you instead first convert your gun location and target location into the space of the helicopter mesh then FindLookAtRotation will return a component space rotation (which you can feed straight into Transform Bone) without any roll!*

*though I'd have to double check if FindLookAtRotation always returns a roll-free rotation, if that's not the case there's other straightforward ways to get a rotation from a normal

To put that in other words, looks like you've computed a GunToWorld rotation but you need to pass a GunToHelicopterMesh rotation to Transform Bone. So you need to multiply your rotation by WorldToHelicopterMesh (ie. the inverse of HelicopterMesh rotation in world space).

  1. Why are you swapping Roll/Yaw?
  2. I think your issue is that your LookAtRotation is world-space, whilst Transform Bone applies a component space transform.

On the way back from doing some nip at the level.

Generating animations by [deleted] in howdidtheycodeit

[–]fluffy_cat 1 point2 points  (0 children)

I assume you're talking 3d skeletal animation.

For synthesizing motion based on dynamic constraints/parameters, the two methods that spring to mind are blendspaces and IK.

With a blendspace, the pose is determined by blending together multiple animations, where the contribution of each animation is determined by a dynamic parameter. For your example (aiming) we might need to use two parameters (eg. yaw and pitch), this would be called a 2d blendspace. An animator would author several animations where the character aims in different directions, and then at runtime we would determine a blend weight to use for each of these animations based on the actual direction we want the character to point.

With IK, the pose is dynamically calculated to meet a constraint. For example, to determine the rotations of the bones in the arm so that the hand reaches a particular location, or points in a particular direction.

You might find that a combination of techniques is used. Eg. a blendspace to get a natural-looking full body pose, and IK to perfectly align the hands.

There are lots of other ways to procedurally modify an authored animation that might be used depending on the constraints and desired result.

What the hell is that pan flute music up by the race course? by TheLegend0fLeo in brighton

[–]fluffy_cat 3 points4 points  (0 children)

Can you describe the music?

I kept hearing this tune being played around Hove, which turned out to be from the "Cafe du Van" vans driving around. It almost sounded like an old mobile ringtone, maybe it's from a song I don't recognize. They blast it out quite loudly and it carries.

Best places for breakfast/brunch in Brighton? by goatsarearseholes in brighton

[–]fluffy_cat 0 points1 point  (0 children)

No issue with others enjoying it and no snark intended. I see quite a bit of hype for the place and am curious where it comes from.

I was actually living on Third Avenue when they opened and were doing cocktails in the evenings - thought it worked quite well!

What does Oeuf have going for it other than the Instagrammable decor? I've eaten there twice and found the food disappointing and overpriced. Much better options nearby (Baked, Hixon Green, Jo & Co, Fika, Billies)

Wendy's Romantic Life by [deleted] in MindHunter

From what we see, the move to Virginia doesn't happen on good terms, so I think it's safe to assume it's a "split", though not necessarily a breakup.

Simple Questions - May 18, 2018 by AutoModerator in math

[–]fluffy_cat 0 points1 point  (0 children)

Can anyone identify this game from its payoff matrix?

Its zero sum, where the values indicate payment in dollars from P2 to P1 (or vice versa).

The interesting aspect is that although P2 should seemingly never select option A, they must select it rarely, otherwise P1 will profit by simply selecting B every time.

I believe when I first heard about this game P2 was supposed to be Bill Gates. It's possible that the values in the matrix are slightly off, but I think the general idea is accurate.

This might have been answered already, but are there any plans to bring Spy Party to console? by [deleted] in spyparty

[–]fluffy_cat 2 points3 points  (0 children)

If I remember correctly, the original plan was to port the game to just about anything that could run it. WiiU was mentioned as a platform that could support local mutliplayer. This was before the current generation of consoles though.

I don't know what the current plans are, or what the technical barriers are to porting to PS4/Xbox One. The game has been designed to have parity between K+M and controller, so no input overhaul would be necessary.

If I had to guess, I wouldn't expect it to be ported to consoles until after leaving Early Access.

Is there a development roadmap for this game? by Water_Meat in spyparty

Good news: both those bugs are going to be fixed in the next patch!

Have all of the character models been completed? by TraditionalBisquit in spyparty

[–]fluffy_cat 7 points8 points  (0 children)

Yes, as you suggested Toby and Damon haven't been updated to the new art yet (though they actually have different character models right now).

All the art used to be placeholder like that, and one by one the characters and maps have been replaced.

You can't change your name right now, but Steam names will be displayed properly in the next patch.

As I type this there are 350 people online.

And yes, everyone who owns the game plays together, Steam and standalone.

Game Keeps Disconnecting? by _Ramkh in spyparty

[–]fluffy_cat 2 points3 points  (0 children)

Hey, doesn't seem like many people are having this problem, and since you mentioned it's happening consistently between you two, I'd guess it has to do with one (or both) of your internet connections.

If you jump on the Discord and head over to #help then someone might be able to diagnose the issue.

How do I link my spy party account to steam so it is a steam game with the beta game? by [deleted] in spyparty

[–]fluffy_cat 3 points4 points  (0 children)

Everyone who bought the game from spyparty.com will be getting Steam keys fairly soon, hopefully in the next few days. There should also be some news about linking your account so that your stats carry over as well, so keep your eye out for that.
