1. Most of the time what's on screen has nothing to do with what the narrator is talking about. This video actively distracts from its content with colorful noise. 2. Some of the things described are just default settings, like reuseCollisionCallbacks. You cannot optimize your project using something that is already active by default.
From my point of view, it is the best graphics engine created with C # features! Yes this can be very important into a game development. I was able to run Unity last version on Fedora 33 distro Linux with 10 Gb RAM and very old NVIDIA Corporation GT218 [GeForce 210] (rev a2). The asset store tab don't let me to write on search bar and the only way to import assets was to add it to my favorite and then use these. Some bugs can be avoided or not, but for those who are going through the learning stages and changes created by the development team, it takes time for me. Thank's for help.
I am currently in development and I build a house now adding props but most of the stuff on shelves or bookcases are physics and so many of them really decrease my performance.
As per usual: hey this is unity, heres some tips with little to no detail of how to implement them or what they actually mean, but its okay thats why you guys exist
According to this video it's to prevent double FixedUpdates if the frame rate drops a little. The assumption is that you will want to run at 60 fps (or more).The physics rate has to be lower than the frame rate to give some wiggle room. Whether 1/6th is enough wiggle room depends on your game, I guess.
But some optimizations demo and working scripts would be very recommended instead of "you can do this and that". But because of the never finish Dots system at all the script stuff will never work without fundamental errors. Unity can create master classes Infos in Seconds!!
1:59 Can you dynamically set the physics time? So if my game runs at 30fps on my machine, it will be different from someone else’s machine where the game might run at 60fps.
Your so called physics time runs on something called fixed update. This is the same regardless of framerate. So it doesn't matter whether it's 10fps or 60fps. Fixed update is fixed.
how come when making a game like billiards, balls are always more attracted to sticking to edges? I tried all kinds of physics material properties and nothing got rid of this sticky behavior.
For some more in-depth troubleshooting, we'd recommend sharing this experience with other creators either on our Discord channel, or in our Forums: discord.gg/unity forum.unity.com
@@VehiclePhysics It's the correct advice for majority of people, so thank you. However, unity's physics behavior where rolling objects are attracted to closest edges persists no matter what the bounce threshold is.
I had configured a perfectly bouncing ball in the past where it would keep bouncing forever (friction = 0, bounciness = 1), so at least I know it can be done. I recall having the problem of stopping bouncing, but it was fixed by setting Bounce Threshold to zero.
@@VehiclePhysics The problem isn't the bounce part. It turns out rigidbodies are somehow attracted to other colliders when they're freely rolling on the ground. It's like there's a very slight magnetic field between the rolling ball and the closest wall. I think it only aplies at a certain close distance.
You should set the fixed time step based on how much iterations you need to get a coherent physic simulation for your situation. At low frequency ( 1/10 ), physic is more inconsistant, objects can easily go through others if moving at high speed and bounce are way to big. At higher frequency ( 1/50 ) physics will be more accurate, and then more realistic.
For something like a phone game you don't even need 30 iterations a frame, and can probably tone it down to like 15 depending on your game. It is what I did in a professional project and got huge speedups.
@@herohiralal3255 My game is an endless runner with a little different concept, I'm moving some pivot objects with transform, while moving character with physics. When I increase fixed time too much, some sync issues are apperaing. I was wondering, how much can I increase fixed time for performance without getting sync issues(with 30 target frame rate)
@@pronotron You can probably just stick to the default 50 Hz. That way you get two physics updates on most frames and sometimes only one. If your frame rate is fairly stable you should never have to do three physics updates on any frame. The bigger question is why you would want to target 30 fps? Mobile game?
put a map image in a circle mask, move it with the camera with the required offset to adjust for the difference in coordinate systems. Like so (mapPos = CameraPos*differenceInScale+Offset.
I was making a game I published it but I shearched it up on the play store and the apple store its not there and I want to make a animation its not working and I want to make a live event but it won't let me write on the event
