Tunicate posted:IIRC Lua doesnt' have a match statement or switch statement built in, right? Lua doesn’t even know what a constant is, so, yeah basically. But, you can very easily abuse its key/value table system to do more or less the same thing, if you’re trying to be more efficient.

yeah was gonna say, in lua your options are basically do the ten thousand line if-else, or do some really bonkers table magic poo poo.

You can indeed do table magic poo poo, something likepre:match_table = {
plus = function(x, y) return x + y end
product = function(x, y) return x * y end
}
function fake_match(x, y, action)
return match_table[action](x, y)
end
print(fake_match(2, 5, "plus"))
print(fake_match(2, 5, "product"))

All the data in Grimrock games was Lua table magic poo poo too and it was great. Being able to spice up data with the occasional function or defining objects in bulk with for loops for example is a nice luxury to have.

Jabor posted:But it feels like a ton of boilerplate to write it that way when you're starting out with only a half-dozen cases, it's often easier to just start with something that works well at that small scale and then keep growing it. and once you have a pattern for how you add new content, it's way easier to stick to that pattern than it is to rearchitect everything. And, again, this is fine, it's a simple process, you know where to go to look up how something works. About the worst I can say about it is that it's hard to do comparisons of cards without a lot of scrolling around. The performance penalty of doing thousands of string comparisons every time a card needs to be scored is, honestly, negligible these days.

Lua caches strings anyway, so the penalty for string comparison is already reduced as a language feature. LuaJIT is such a nice language.

And if you end up needing that often enough, the pattern is simple enough that you move your data over to some other tool (like an Excel/Google Sheets spreadsheet), then write a really basic CSV importer that generates a string of that chain of ifs based on the data in the sheet, and you literally run it and copy paste the code in when you're done balancing the numbers. You can even automate it into your build pipeline.

megane posted:You can indeed do table magic poo poo, something like It's weird to call this "magic table poo poo," since that implies to me that it's hacky/messy. It's the same as using a dictionary/hashmap of anonymous/lambda functions, which is extremely common in many languages. I do it all the time and it's a very normal alternative to giant if/else blocks. They don't need to be replaced if they aren't a problem, but this is pretty much the standard for how you would do it. Edit: My giant conditional blocks are implemented in shaders inside a critical loop that gets run hundreds of millions of times per frame and needs to be as optimized as possible. I use case statements Double edit: I'm not exaggerating. That case statement is evaluated up to 100 times per function per pixel and there can be up to 32 functions, so that's a worst case of ~26.5 billion evaluations per frame in 4k. Worst case can't really ever happen, but 100s of millions is common. It still runs at several hundred FPS on my 3090 (for now, until I bog it down with more poo poo).

Yep. One of the reasons Lua appeals to me it that it gives you one simple-yet-powerful tool, the table, and then you solve pretty much every problem by applying that one tool in clever ways. You can implement Sets by using tables "backwards," with the elements as keys and true/false as the values, for example. That's definitely a downside for many applications, but I enjoy it as a mental exercise.

In one of the legacy applications at work the previous dev suffixed every 0-indexed thing with _indexStartsAt0. As it's written in C#, it makes the source quite a thing to behold.

I appreciate how lean and elegant Lua is, but I haaaaate having to bring my own tools (and/or find and install others') to the party. I want a robust standard library that ships with the language.

I always have handy this list of curated Love2D libraries for literally everything you can think of for Love2D/Lua gamedev. For objects, 'hump.class' or 'middleclass' are both good picks, and for asset management 'cargo' is pretty much the easiest way to pull in any file data for quick use.

I have a lot of goons in my twitter feed, and just as many, if not more, composers and sound designers as well, and while I'm sure those two groups overlap, it's still very rare. Anyway, I know of them outside of anything forums related, or at least I assumed I did, but at this point, I wouldn't be surprised if they were a goon.

I find that on Newgrounds my games get a lot more visibility than on Itch just because they do a lot more to put the games in front of people. For instance theres an approval system when games are submitted to keep the utterly terrible stuff off the site, which means users are encouraged to play new content to vote on it and gain experience on their accounts. Whereas over on Itch I don’t think theres anything of the sort. I also think that with Newgrounds being less saturated these days compared to Itch you’re more likely to have your game played if it is good because it’s not drowning in a sea of other content. Using my most recent game as a case study, despite it winning a featured game jam on Itch its only had 361 players on the site. Meanwhile over on Newgrounds where it is just another game like any other the game has already had 3034 players at the time of writing. I released the game to both at the same time.

HTML5, which a good few modern engines will export to. All my stuff for example is GameMaker Studio. Though theres still a few guys on there using Flash which Newgrounds will run through their own emulator.

the fact that you can just go to the website and play games is probably why it attracts a big audience of people who just want to go to a website and play games. as opposed to itch which is a whole bunch of other things first, and actually playing games in your browser is a bit of a side hobby.

Yeah you’re probably right. For me I like to develop my games browser first because I don’t have think they’ll make much money anyway if I were to try to sell them and I’d rather just get them played by as many people as possible. And I think making them playable in browser eliminates a lot of blockers that might prevent a person from bothering to give it a go.

So ... a ways back in this thread I suggested doing something like "Idea Crafting" as an alternative way for the player character to come to new conclusions about what's going on in the world around them. A few people pointed out some games that used similar mechanics, although nothing quite like what I wanted to implement. I've got a very rough prototype working now. I've been porting "House in Hellworld" over to RPGMaker specifically because I wanted to test out two concepts: 1. The idea of mimicking the soul-crushing grind of a retail job. This takes place by using RPGMaker's turn-based combat system, and repurposing it so you wait for customers to enter, browse the store, and check out. You can apply "customer service" to do things like greet them and help them find things but all this does is keep the manager from complaining at the end of your shift and for the scope of the game has no impact. It's just there to try to get across the tedium of the player character's day. 2. Idea Crafting. Every major event in the game gives the player information which they can then reflect upon or analyze while they sit at their day job. The player investigates a haunted house at night, trying to find a great treasure rumoured to exist there, only to be driven out by one of the various supernatural horrors within. During the job, they can think about what they encountered and combine it with some other information they have to see if they can puzzle out what's going on. This is an example used in a battle test run -- normally you wouldn't have all the information in the game. The player combines the horror of the "Tub Head" against a prior experience with a head found in the freezer. One of the conclusions they come to is that the heads are illusionary. (I haven't included any other potential conclusions yet, but if I do the player gets both) https://i.imgur.com/AgfE00L.mp4 I just wanted to post it here and get people's reactions to it. Ideally I'd prefer to have a drag-and-drop system but that would require creating a new engine or learning a new game engine and I knew I could prototype it in RPGMaker pretty quickly. The original game was a visual novel in Ren'py.

I want to thank various posters here for mentioning Picotron. I had got into a real rut / burnout with my frankly too ambitious 3D Godot project. I downloaded it on a whim; I had not heard of it before. With no prior experience in Lua, I have a basically functional Pacifism clone after 2 evenings (not a brag, its more that the environment is so frictionless to work in). But that's not really the point - the point is I had an absolute BLAST doing it, to the level that I am counting the hours in between me and my next opportunity to dive in. It's obviously not for everyone and it's in Alpha anyway. But using it has made me feel creative and alive again! ~all is full of, tables~ (to the bjork melody)

Lua has reignited my joy of coding again too! To the point I spent a chunk of my bonus on a Playdate just to make dumb things in lua. The community seems neat and it kind of has “real life pico8” vibes. In terms of the online presence anyway… the thing hasn’t shown up yet so I can’t comment on the device itself I haven’t actually looked at picotron yet because I’ve been deep in various love2d things getting my feet wet with more advanced lua things but it sounds neat. Right now I’m trying to work out the maths to make a mode7 ish densha de go clone like Cab Ride on pico… though I might just try doing it in real 3d on the PD anyway. i’m hesitant to actually do much while I’m waiting for the device because the simulator on pc doesn’t match performance at all.
