So good to see the code that runs Dauphin. If I saw those 300+ errors after the conversion, I would have freaked out and went back to the old version of Godot. 😂😂

@neekitsart990 Год назад

For the sailing system, by far my favorite that I've ever experienced was on the pirate island in Poptropica. Each island had different trade rates for different items based on what their primary export/imports were, and that meant if you wanted to sell your bounty at a good price you had a reason to sail around. There were recruitable NPCs to add to your crew on each island who each had an ability that made an aspect of sailing better, and while you were sailing, pirate ships and giant sea monsters would approach your ship and try to attack you. If you won you got loot, and if you lost you lost some loot and were sent back to the last island. The loot was what you traded on the islands to get money, and money let you recruit new NPCs. If you didn't have the money to recruit one, it was an incentive to go back out sailing to make money, and also to return to that island later to get them. It was simple but surprisingly well built out. It definitely wouldn't be something you could copy directly, seeing as the themes are pretty different, but I loved sailing as much as I loved being on the islands, and it encouraged me to go out and explore the generated ocean. Maybe something to look at for inspiration?

@manchmalscott Год назад

Just a heads up, beta 8 introduced a breaking change by removing the trigger update mode from animations, and because the update mode is stored as an int in the scene file, the consequence is any animations using the capture mode will break until you manually go into the tscn file and change the "update": 3 to "update": 2 for each track. I just got burned on this with one of my projects I've been doing in godot 4. They're aware of the issue, and the animations *can* be converted by hand editing (change 3->2 and 2->1), but there isn't any automated tool to do it.

@twenty-fifth420 Год назад

Im new to dev and semi-new to game dev in general. But how many breaking changes in general have been patched from 1 to 8? I just want a stable 4 soon lol. I have 3.5 chilling in my computer learning other dev stuff lol. I can be patient, especially since I plan to keep/use both. (Mostly for Visual Scripting). Just curious, I hope this aint too much to ask. 💔

@Crazylom Год назад

I think with Microsoft VS you can go search the string in every file that contains it...which means you can basically in an instant fix it all. Hope that helps :P

@megahombre24 Год назад

Even without any knowledge on godot, I enjoyed the video a lot and think it was interesting to see this conversion process. It reminded me of when I switched my project in unity from the light weight render pipeline (LWRP) to the universal render pipeline (URP), however that did not nearly require the amount of effort that you had to go throgh. However I think the feeling when it was finally done is comparable for sure, it felt really great and enabled a lot of cool new features. Congratz my friend and keep it up, looking forward to the next devlog. Much love from germany ❤

@Meaningfulcausesstudio Год назад

@BastiaanOlij Год назад

I was surprised to see you tackle this conversion, I wasn't expecting Godot 4 to offer that many new features that you were hanging out for as a lot of the work focused on 3D. It did look like totally doable, it doesn't look like you ran into any issues that couldn't been solved or set you back. That said, your perspective at the end of the video was interested, yes it took you a month to convert and that means a month of not moving the project forward, but I'm actually surprised seeing the size of Dauphin and seeing you've done this along side of family, vacation and work obligations that it only took a month. And lets face it, a month in the total time it takes to tackle a project of this size, is a small price to pay imho. So damn impressive, keep it up!

@skyscraperV1 Год назад

Great video - it's really good to see a focus on the technical stuff, code, decision making and problem solving stuff :) I know you also like to make your devlogs a bit broader than just coding, and that's good too - but I think a lot of people are like me and love the tech stuff even more! Keep up the good work :)

@intangiblematter_misc Год назад

Little tip! I noticed your dialogue doing a weird wrap (39:20). In Godot this will only happen if you're passing the characters to the textbox one at a time. Instead you should try putting it all in the textbox, then increment visible_characters until the whole string is visible!

@gonzo191 Год назад

for your _request_state function @22:54, instead of doing if current_state = A || B || C etc, simply add all of your query states to an array and check if the array has the current state *e.g. ln 26 changes to* var query_states = [move_state, attack_state, cast_state, fish_state, forge_state] if query_states.has(current_state): change_state(idle_state) *[OR]* if current_state in query_states: change_state(idle_state) *[OR]* extract all of those if checks to a function to reduce repetition like the following if requested_state == idle_state: ....update_state(idle_state, current_state, [move_state, attack_state, cast_state, fish_state, forge_state]) // English: update current state to new state when the current state is any of the query states *func* update_state(new_state: State, current_state: State, query_states: Array[State]) -> void: ....if query_states.has(current_state): ........change_state(new_state)

The Tilemap system is one of the best upgrades in Godot 4. I dont use it as much since im using 3D but the little I did it just felt much more intuitive. There is a learning curve but once you get it. Its a breeze. My main reason for the upgrade was for the Vulkan Renderer.

@graydwarf22 Год назад

Found your Signals setup interesting. Was trying to figure out what value you get from that design (calling a function to call a signal seems redundant so I'm missing something). I was also surprised to see you referencing scenes in your autoloads. I haven't thought to do that for anything yet. I guess it allows you to have multiple scenes open at the same time. Trying to think of a situation where that is useful over global scripts/state management. Your water transition is neat and your blur effect with/without mask is fantastic. (first time visiting/seeing your game). Your slot-dots are an interesting design choice. Reaching the end here and wow... an entire month (with some PTO mixed in) to convert from 3.x to 4.x. That's brutal. I appreciate the share and you being an early adopter so I don't have to. ;P

I was missing your devblogs, i learn a lot from them!

At match patterns you can just check if the state is not the requested status with operator != (i haven't used godot and i am not sure if there even is that operator but in every other language there is so that could just make the code easier to read)

Frankly, the fact that a new major engine revision *still in beta* only had ~350 errors is kind of amazing. Unity projects can result in dozens of errors between *minor* revisions and in AAA development it's not uncommon for redactors to result in thousands of errors. Godot is really so amazing to work with.

@Arctan95 Год назад

Hey Ben, I was wondering your thoughts with regards to source control - namely git vs perforce for game dev. Our studio currently uses perforce as it seems more angled towards supporting both code and larger art, audio and video assets. I suppose, given your project is sprite based you don't run into the file size concerns as much but is it something you've looked at and are you using a premium version of git at all to allow for extra storage? Good call branching the project, as somebody who just updated our live project to the latest (non beta) release of UE5 and have everything break due to an engine bug and need rolling back - lesson learned. Cheers, - J

@pepsiman9093 Год назад

I have to ask, I'm not very experienced with Godot (only been using it for about 6 months) and I've never heard of loading scenes as singletons over scripts. I've been part of the discord for a while but I've never heard anyone talk about the benefits, or even recommending it at all. I kind of just paused the video at 14:42 to comment and ask, but what are benefits/downsides of using scenes/scripts as singletons?

@Hovrawl Год назад

It looks like they changed `match` to function more like a `switch` statement in other languages with the constant requirement, you should have been able to use your previous setup with only have to change your variables into constants: `var idle_state = : State = $"Player Idle State"` can become `const idle_state = : State = $"Player Idle State"` I believe GDScript has const values so this should keep your code clean still

@crustydev5561 Год назад

@clray123 Год назад

Congrats Godot devs, making backwards-incompatible changes is the surest way to kill your API/library/engine. The biggest problem is not that you need to change code that uses it, the problem is that you invalidate all docs/tutorials that are already out there.

@fadge316 Год назад

I don't know the code you're developing in but I'll share how I'd go about that match pattern for the states. Have you heard of smart enums? Imo enums are meant to be dumb, but I think this could provide a nice solution for your problem. Basically you can define your state's in the class, as part of that definition you could specify in a list which states are allowed to transition from to that state. Then the change state method would just take the current state and requested state, check if that's part of the allowed transition from list. Would remove all those if statements and would scale better because you'd just have to define a new state and it's allowed transitions, all existing code would work. Might not be the best solution but I think it's better than the current 👍 Edit: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-v6cYTcEfZ8A.html There's a great video on smart enums
