These tips videos are really nice! Would you like to do a RUclips collab with us on some Godot 4 tut or tips or something? For tweens, I'd expect remove_all() to work moving forward because it deletes the registered tween animations, so it shouldn't be able to continue the animation once the data got deleted. But that's definitely been a little confusing, and I've made the mistake of calling stop_all() over remove_all(). Thanks for the video!
If you are still collecting GODOT tips, I have one more for you: You know there are numeric values that have an slider in the inspector and other don't? Well, even they don't have an slider you can click and drag the number left and right to smoothly change it. But that is not all: hold SHIFT to make change slower, which is useful when you need more precision, and hold CTRL to snap the value to an integer. I did know I can drag the numbers, but not that SHIFT and CTRL had an effect while doing it, until very recently.
Just started using Godot and this little tip is something most blender users will intuit. That’s so far, one of my favourite things about Godot. I hated navigation and that in Unity. But Godot is identical in terms of viewport controls and little things like this which I love to see
Forgetting that arrays and dictionaries are passed as references: A = [1,2,3] B = A B[0] = "hello" Print(A) Output ["hello",2,3] The cause of so so many of my bugs by forgetting B = A.duplicate()
@@PlayWithFurcifer I didn't think I had but then tried to learn a little GDnative C++ and bugged up the other way around because C++ doesn't pass them as references unless u tell it to.
For some reason, if make an one-shot animation with 100% explosiveness, it has a massive delay before it can emit again. Meaning, if you want to make these kinds of particle effects often from a single source, like a cloud of particles when you jump, you should spawn a new particle object each time instead. (and delete it afterwards of course)
I recently had fun debugging material shaders (Godot v3.5) that should be unique since they would have different input parameters. Looking at the tscn file code shows the ids for them in the scene tree to see that they are not made unique. In my case I was setting the next_pass property of a material to the shader. Another debugging trick is to print the name of the material or shader instance, this prints its reference id to check if the same ones are being used. To make them unique I ended up duplicating a master version of my material in code.
"Not making stuff unique". This has given me such a headache that I now frequently make any node's script a tool script and include a setter for resource exports that uses duplicate() to set the resource variable to a new unique instance of the resource automatically. This has been saving me the headache of making them unique every time, AND I can filter from the setter function and include whatever other conditions I need/want.

Holy S. I'm implementing this is_instance_valid() throughout my code immediately. I had some edge case problems with checking for null and didn't know why that was. THANKS!
I had slow load times with mp3 and even crashes (my guess is that something odd with the encoder caused an edge case in Godot), in particular in web exports. Ogg is much better. Although my experience is that Ogg is slightly larger (you say it is smaller?), it loads faster (it seems that with mp3 Godot takes a little longer to fill audio buffers).
OGG is a bit larger with same bitrate, but with a slightly lower bitrate it is both smaller and better quality (as far is my research goes, i dont have the ears to confirm that)
I started my own game with MP3 files and I quickly changed them into OGG files. By lowering the quality setting a bit (I use audacity to convert them), they're really smaller in my project and I could not notice any audio quality loss even with a headset.
'Await' is so backward coming from gsc where every called function must return before proceeding. It's nice using actual results & not function states. If one needs to run a function simultaneously for whatever reason, just gotta specify it with a single keyword without the need to inherently proof any other relevant script. It's irritating at times calling functions in Godot with seemingly no absolute guarantee of a timely return & having to proof stuff when I just want to expect a result first.
Well guys, I owe you a tank of *well.. something to drink that the algorithm dont like me to post*... That "is instance valid" literally took me out of a month long suffering spiral... Thanx a ton!!!!!! (And awesome video as always!!)
Yup it was renamed. You can find more info about GDScript 2.0 here: github.com/godotengine/godot/pull/39093 There are quite a few converters in the works. The Godot 4 Beta comes with a converter integrated. Haven't tested it yet though.

There is one other error I see at least once per every page on Godots Q & A Forums : forgetting about mouse filter set to stop of overlaying control nodes :)
That one has gotten me countless times in the past, after about the 20th time I think I finally learned to check for it but it can still be tricky to track down in dynamic UIs.
@@beidero Just dealing with that today actually. Working on a card game framework and mouse events for overlaying cards is harder than expected. I played around with visual click tracking (everything is pure Area2D) or control based click tracking (treenode traversal with dead-ends) . The latter of the two took a bit to figure out.
That is a very common one, yes. Although it is usually something easy to spot (like a background element), for those cases where it is really hard to find, here is an extra tip: With the game running, open the debugger panel on the bottom, and then go to the Misc tab, it will show you the last control you clicked. You can then start clicking around and see there what is intercepting the clicks. You can double check with the Remote tab of the scene panel, also while the game is running.
@@Theraot A lot of people, me included, expand control nodes to fullscreen, while making visual changes only at the small part of it. That is why this problem is so hard to spot :)
Here are some mistakes I used to make: 1. Signals + Multi-Threading = no no 2. Forgetting to free a Thread with 'wait_to_finish()' 3. Setting materials on a mesh resource instead on the MeshInstance. 4. Setting velocities (or even worse positions) directly on rigid physics bodies. 5. Using bodies instead of areas for bullet hit detection. 6. Removing a node from scene tree without calling queue_free() 7. Statically typing arrays as function parameters can cause funny lines like 'Cannot convert argument from Array to Array'. 8. Not understanding that 'await' is in NO way or form multi-threaded but a coroutine instead! 9. Setting values of locals within a lambda which have the same name as a variable in an outside (global) scope has no impact on the values of the variables within the outside (global) scope! (Note: 'global' means something different here than member) 10. Placing a GIProbe (it was Godot 3) not into the geometry 3d-node-based part of the scene tree, which causes the probe to have no effect at all.
"Make unique" has a cousin in "Local To Scene", a property (found under Resource in the inspector) that makes the resource unique when you instance scenes dynamically.

I wonder if there's an easier way to make a "player limited vision" without having to use light2d and lightoccluder2d? Like, the player not being able to see through walls and instead just see darkness on the other side.
Pretty much sounds like the main application for light 2d. Maybe you can build the occluders programmatically from collision shapes? Someone might have solved this already
@@PlayWithFurcifer I've checked and tried with light2D on the player and the occluder on the wall tile in my top view 2d game, but the "darkness" gets rendered on top of the tile so I can't see the wall's sprite, meaning I can't make 1 tile walls for example, because they'll just be completely black and it looks bad :(
