[@firearmnightcore3054]

note that fixed update fps can be changed in the settings, and It was not framed-dependent. Meaning that if your game had a sudden frame drop, the fixed update will still run.

[@Jecsham]

So its like an internal ticks system from unity then?

[@myhvKun]

And if it's not, would that be the cause why some games (especially old ones) run faster/slower based on fps? Like how Cossacks (an old RTS) goes in to hyperdrive on modern systems.

[@saniel2748]

This is so not true

[@Jecsham]

@@saniel2748 explain 🤔

[@saniel2748]

@@Jecsham The FixedUpdate frequency is more or less than Update. If the application runs at 25 frames per second (fps), Unity calls it approximately twice per frame, Alternatively, 100 fps causes approximately two rendering frames with one FixedUpdate. This is from docs. Also FixedUpdate doesn't literally run on fixed timestep, it just runs multiple times to cover passed time, if this makes sense

[@MrJellekeulemans]

I already have a basic understanding of some of these 100 sec topics (like this one), but somehow you make every topic click a bit better in my head. I for example never realized that there are just 3 engine components, and how clearly the game engine is structured. Amazing videos!

[@arvidd]

A small correction: input should be taken from the Update loop for a more responsive experience where as physics calculations and for example adding forces to an object should be done in FixedUpdate where the frame rate is stable and won’t change drastically. This is how Unity prefers it.

[@szaboattila155]

This should be the #1 comment as its a huge oversight in this tutorial. Never poll input from fixed update.

Take user input in Update() and perform physics updates in FixedUpdate(), creating a “state machine” is a common way of handling this (if you take input in FixedUpdate the user will likely run into frequent input lag)

[@amirgamil]

Be careful! Looks like you might have gotten replied to by a scam account posing as Fireship!

[@C4Oc.]

Always take player input in the Update function. Taking it in FixedUpdate instead will result in weird and very frequent skips (input gets skipped because it doesn't match the timing of the FixedUpdate function; I assume even more so if you change the timing of it)

[@daskampffredchen9242]

@@C4Oc. Explains a lot for me. For some reason one eBook I use for learning put it into the FixedUpdate. And when moving in the Editor I have problems with stuff like Spacebar for jumping. But for some reason I dont have the problems when playing the Released game

[@jasonyesmarc309]

Also from my years of using Unity, it seems that Update and FixedUpdate should not be treated as being thread-safe with each other. If you have information that is used in either of these, then implement a system that performs the calculations internally, and finally applies all the results upon the final instruction. On systems running slower than 60fps in your game, Update methods will be interrupted by FixedUpdate at an arbitrary point by the engine, in order to ensure the physics remains stable during lag spikes. It only seems thread-safe on systems running faster than 60fps, so any devs using bleeding-edge hardware will not catch a lot of bugs found by players using dated hardware.

[@iamawatcher9201]

And now it's ruining game makers by charging them per download for games made with Unity. Meaning any redownloads, piracy, and reinstalls will actively hurt developers just so Unity can line their pockets more. (hopefully they revert after the amount of blowback they're getting rn)

[@st.altair4936]

They most definitely will revert. But it'd be pretty stupid to stick with Unity after this. Foss software like Godot is the only way. I have no doubt Unreal will also do something like this at some point.

Now looking back at his videos I am shocked how many things he must have been through and tried to get to the point of understanding enough to make a video. Damn this guy is nuts.
