Never Wait For Compilation AGAIN! (Unity Fast Script Reload)

Unity compilation getting you down? Check out Chris Handzliks FastScriptReload, which is FREE and OPEN SOURCE. Instead of full domain-reload and script compilation every time you make a small code change. This tool will automatically compile only what you've changed and immediately hot-reload that into current play session.
Iterate on whatever you're working on without re-entering play mode over and over again. We'll look at importing, and basic usage.

[@ramsey2155]

Does this also work for editor compile time. I deal with a lot of editor scripts and it would be so helpful it you could hot reload custom editors Edit: I just installed the package, sadly the second it got imported unity threw a bunch of errors. mainly Illegal byte sequence errors. I assume this is due to the editor not using double byte characters. If I ignore the error and enter playmode unity just crashes. This issue makes the this compiler unusable

[@nikhilvardhantawania4591]

I come across this asset a month back on reddit, downloaded it but never used it. Your video made me use it and it is awesome. Thanks much

You're very welcome, Mike. I hope you get to use it and it saves you those seconds, which turn to minutes and all! :)

[@flurinjenal374]

I don't understand how to use it. It disabled auto-reload but when I manually reload (CTRL + R) it still takes ages to compile.

[@qwerTeamxyz]

SpeedTutor! We need a Code Pad door locker video!

[@SpeedTutor]

I did create a new tutorial recently that helps you create a keypad UI :)

[@BravoPhantom]

That's an incredibly valuable asset for all developers! 🔧 Before discovering it, I used to endure agonizingly long script reload times when switching to Unity 2021 LTS. But then I stumbled upon a game-changing Unity Tip that revolutionized my workflow. 🚀 👉 Here's the trick I found: ✨ In Project Settings > Editor > Enter Play Mode Settings, enable "Enter Play Mode Options" and disable the other two options below. This simple adjustment made entering Play Mode lightning-fast, taking just 2-3 seconds every time, regardless of project complexity. However, it comes with a caveat (which I learned the hard way and now use with caution). By doing this, some compilation tasks, including static instances, may be skipped. So if any unexpected issues arise in my projects, I simply press Ctrl + R to recompile and resolve any related problems. 👉 But here's the big question: Does this method potentially miss crucial items during compilation, especially the important ones? 🤔 What if hours are spent troubleshooting a seemingly mysterious error in the game, only to realize it was a simple compilation issue all along? The struggle is real! ⏳

[@SpeedTutor]

That's a good bit of advice, thank you for sharing. I think it's about taking advantage of time saving tools and then being in a habit of doing a manual recompile every so often and especially if you see issues arise. So you can get the best of both worlds. :)

[@BravoPhantom]

@@SpeedTutor I'm amazed at how you respond to every single comment on your videos even after a month 😀 Sorry, if it seems to be like a statement rather than a question... 👉 My point was that in that "Enter Play Mode Setting", it is important to use it with caution and keep an eye out for any unwanted errors. 👉 Does this Fast Reload Script also comes with any disadvantage like that; missing any crucial items in compilation, etc. If it does then I shall not use it in any major projects or long-term projects, as it will irritate me so much... to focus on finding errors because of compilation, instead of finding errors because of mistakes in the code. ? 🙂

[@SpeedTutor]

Haha, I try my best to answer every comment and I often comment on the videos that are 8 years old too! :) Sadly that's not something I can answer because I don't use it in any of my projects as I'm not working on something big enough to warrant it. It's something best asked for the developer of the asset because he'd be able to tell you more! :)

[@BravoPhantom]

@@SpeedTutor Great 👍 I'll email the developer "Chris" and asked about the backend of how this works. Sorry for the inconvenience 👋

[@irtezamasud1079]

unity should make a feature like live coding in unreal. this solution seems promising.

[@SpeedTutor]

Definitely, with more development from the community it could get better and better.

[@justlama0]

thanks but ... Mac Silicon Editor version not supported

[@muajin]

Do you by chance have a good tutorial on how to export android apks? I keep getting a debuginformation file instead of the apk when i build and buildmethod errors in unity. :(

[@SpeedTutor]

Sorry, I don't. It's not something I'm very experienced with, really sorry.

[@boyar3033]

Is this asset also meant to be used to speed up compilation if it's NOT done in play mode ? I rarely edit scripts while in play mode.

[@SpeedTutor]

Yes, playmode compilation is just another thing it can do as I recall :)

[@perinohere]

saved me a lot!

[@SpeedTutor]

[@jcd9456]

Mine is messed up. My script wont compile. How do I uninstall this thing? Now I always need to manually compile (ctrl + r) Using Unity 2022.3.2f1 LTS

[@SpeedTutor]

You most likely manually uninstall by deleting the files and turning the full compile back on in the settings :)

[@49wares]

Wow, its a wish come true 😁😃

[@SpeedTutor]

Haha, great developers do that for us all! :D

[@OneTime_12]

You got anything for "reserialize assets unity" or "waiting for unity code to finish executing". These will take forever. Literally just clicking will cause them to go off... Any way to speed this up.

[@SpeedTutor]

Not to my knowledge, sadly. It's an annoying, thing I know! :(

[@BarelyTryingStudio]

Question on this, what’s the difference between this and hot reload ?

[@SpeedTutor]

This one is free, I think Chris was the first one to get this created - It just wasn't worth him making this a Unity verified solution as there were too many hoops to jump through.

[@TheCookingPixel]

Thanks for the video... Subscribed 🔔 Excellent....I downloaded and tested it, works amazing. I tested in both play mode, there are no issues and script is reloading very fast. Note: even the developer mentioned that in edit mode it is in experiment only, But I tested in edit mode too, and it is working perfectly

i got a question, does this work on playmaker as well?

[@Chris_Handzlik]

I've not tried it with playmaker, I've got a feeling it won't help that much unless you edit scripts with playmaker?

[@bluzenkk]

i have both Fast Script Reload (FSR) asset and the Hot Reload (HR) asset. Its funny how they have different approach. In FSR, it is require to turn off unity auto refresh, but in Hot Reload, it is require to turn On auto refresh...

[@SpeedTutor]

Which is your favourite?

[@Chris_Handzlik]

Are you sure? That's from their FAQ page, as far as I'm aware the approach is very similar ``` Here are all the settings Hot Reload toggles when you ask it to: Disable Unity Auto Refresh (only for older unity versions). Can be found in the preferences. Set Auto Refresh mode to "Enabled outside PlayMode" in the Asset Pipeline preferences. Set the "Script Changes While Playing" preference to "Recompile After Finished Playing". This can also be found in the preferences. ```

[@user-pp5ol5zg3p]

Please tell me how can I completely remove this tool from the project and return to the normal reboot mode of unity?

[@SpeedTutor]

I'm not sure as I'm not the developer of this asset, you'd be best messaging him :)

[@BadBanana]

I found it to be less than useful, could be something to do with Photon as it doesn't reload assemblies at runtime, it needs to recompile from a static state before allowing changes but yes seems if for single player testing this could be useful.

[@SpeedTutor]

It definitely could be something that's modified in the future, as this is fully open source so hopefully it will gain more traction! :)

[@Chris_Handzlik]

Photon should be ok, I've been using it with Mirror, if you want we can have a look - just drop a message in discord

thank you so much

[@SpeedTutor]

You're very welcome, thanks for checking out the video! :)

[@solelan1094]

it's not working and i cant remove it at all ):

[@seva4241]

Just curious, when would you need to manually full domain reload?

[@SpeedTutor]

I think Unity does that be default, doesn't it? As in it re-compiles everything you have before moving on.

[@Octamed]

When you stop play mode basically. Press control+r and it'll trigger that. I acutally prefer that as Unity has a bad habit of refreshing constantly when I'm fiddling with multiple files

[@Equisdeification]

It is great, but don't this force you to write all your variables inside the scope of a method? Because you cannot modify the variables outside the method. I guess it's pretty cool for modifying the order of things in code. For variable tweaking you could just serialize the variables in the inspector and tweak them

[@Chris_Handzlik]

you can add new fields as you'd normally. They'll then show instantly in editor so you can tweak as normal variables (some older versions didn't have that though) Bit of an early experimental build that shows that in action kzbin.info/www/bejne/jZS6dZeAqL51m8k

[@Equisdeification]

@@Chris_Handzlik Oh wow, that's so cool, I guess it's because I tried this before that was implemented and I thought it was limiting, this is much better! Thank you!

[@TeppuTeppu]

Have been using unity for years. Didn't know unity can do this. But if this is possible, why isn't unity doing it themselves? Maybe it only works in smaller projects?

[@SpeedTutor]

That's because it always seems like they leave the most useful features for others to create, haha. Maybe we'll see a full implementation one of these days but it's awesome all the same! :)

[@vandermunnik]

Loading scripts normally is still not as bad as Unreal Engine - Compiling is sooo slow in UE;

[@SpeedTutor]

Haha, I don't try Unreal that often but even if Unity compilation doesn't take long the seconds you save thousands of times, adds up in the long run! :)

[@vandermunnik]

@@SpeedTutor One of the main reasons I stopped using Unreal and now fully focus on Unity. You're right those extra seconds add up over time. But I do wonder why this wasn't implemented by Unity itself if it really speeds up the work flow. For me, I'm always a bit cautious with those plugins. The possibility that it may mess this up in my project makes me anxious :P
