[@HA11EYS_COM3T]

You really don’t need music theory to start, absorbing what you can and learning as you go is a good idea :) If what you make sounds good without music theory, it can’t sound worse with music theory (unless you get too caught up in rigid theory) My recommendation would be to pick up composition software or a DAW and just start creating, it’s fun and it’s a good start :D

[@NoodleDoodleWasTaken]

@@HA11EYS_COM3T Thanks for the encouragement! But I've already been doing that for a year or so, and I find it really difficult to do make music without any knowledge. I plainly don't know where to start, what kinda notes should I play and when. So most of my tracks were really frustrating to make, since I just put stuff semi-randomly until it sounds good, which takes a while, and it usually doesn't even sound all that good. I've picked up a class yesterday tho, and it's already helping me a ton!

[@williammanning9323]

"What's the rendering equation? ...I don't know" got me lol For anybody who's wondering, it's the formal mathematical way of saying "for our particular viewing angle of a particular surface point, add up all light which comes into the surface from any direction and happens to bounce towards our viewing angle". That sum of light is written as an integral, because integrals are how you sum an infinite number of infinitely small things. In practice, integrals are usually approximated by summing a *finite* number of chunky things. You may remember from high-school calc, approximating the area under a curve by splitting it into rectangles and summing the rectangles' area together. Similarly, in a ray-tracer we trace a very limited number of incoming light rays, and assume each one covers a fairly broad cone of incoming light directions hitting a broad patch of surface. You get better approximations, a.k.a. more realistic graphics, if you increase the number of rays and decrease the effective size of each one (or decreasing the size of the surface patch, by increasing resolution), so that you're not glossing over so much detail. The integral is defined as the limit as they become infinitely thin, and infinitely numerous, impacting an infinitely small surface. The inside of the integral, describing the amount of light coming in from a particular direction and then bouncing into your eye, depends on a number of factors. Each of them is pretty intuitive once you understand it (for example, one term is the dot product of the incoming direction with the surface normal, because less incoming light is able to hit a surface area if that area is rotated to be thinner from the light's POV).

[@KingBobXVI]

In college I had a project where we built little robot cars that drove themselves around avoiding obstacles using three IR distance sensors, not too different to how a Roomba works, minus the front bumper. I'm imagining a game where you have to navigate a 3d space, you don't have a 3d view, your only visual is three dots on the screen, shaded to represent the distance to the nearest point directly in front of you, and two offset by a 30 degree angle on either side. Maybe another visual element could be a top down map of your path showing where you've been already so you can double back or predict where things might be in the room. Now I actually kind of want to make this, lol.

The overall concept of your game (especially the randomized death date) reminds me of an old art game called The Graveyard by Tale of Tales. In it you play as an old woman visiting a graveyard, sitting down, thinking about things for a while, and then leaving. You can repeat this as many times as you want. In the paid version, she may randomly die during a visit. I seem to remember that if you try to start the game up after the old woman dies she won't be there for future visits, but I can't confirm that.

Very nice.

"Navigating a maze that has no exit but the players dont know that" Have you heard of the wonderful game Crypt, by Valefisk?

[@Sugar3Glider]

The Mathematical Labyrinth: The game starts on a hexagon grid with numbers listed in random locations, these represent the ingress & egress points to the Labyrinth. The number of access points is determined by rolling a D20 while the location is determined by rolling D10s across the table (rolling a 10 acts as 10 and 0). You have a running equation total that begins as the number listed at your chosen entry location and will adjust based on the mathematical equation you used to construct your path. The goal is to travel from one access point to at least one of the other access points, wherein you then choose to exit or continue for more loot either at the same or a different access location. Upon finishing your score is calculated by counting the number of rooms entered while walking through the Labyrinth, with bonus points awarded for loot found, and a multiplier for style (loops) generated in the process. At any point you can pass through already explored rooms using no additional spell points, only movement points, however you cannot enter a room again unless your equation total matches the existing number. You cannot choose to continue through the Labyrinth if your equation total does not match the number listed as the access point and must exit. If it does match you can choose to re-enter the Labyrinth, and if you then die your score will be reduced to the minimum number of rooms necessary to get from entry to exit plus points for loot dropped outside. Re-entry to the Labyrinth costs D20 movement points. No points are awarded if you have not found at least one other Access Point before the Labyrinth collapses. The Labyrinth has a hidden number of points that can be utilized before it will collapse and kill you. Each mathematical equation costs spell points to cast, and movement costs are calculated separately. There is no warning for the collapse, but before reaching your first exit you can divide by zero to retreat through the Labyrinth, which will provide you with half of your score without points for loot, assuming you can make your way back before the Labyrinth collapses around you. 1-4, 5, 6-9 correspond to the direction you move each turn with 1-3 moving to the SW S SE, 7-9 moving to the NW N NE, 4 moving W, and 6 moving E. 5 allows you to move in any of the chosen directions for 2x the spell points for the equation. Loops can only be created by entering a room with a current equation total being equal to the number already listed therein.

[@BobzBlue]

In a voxel game that uses ray tracing would it be theoretically possible to skip mesh building using the chunk data for ray collision similar to a 2d tiled platformer collision system for a performance gain?

[@mettaursp309]

By mesh building do you mean detection of ray intersections with objects already registered & tracked in the scene & available for rendering, or construction/loading of the objects? For the ladder it's better to get it all registered & tracked beforehand. For the former, yeah, those kinds of broad phase checks apply for rays as well. For scenes with triangle meshes it's fairly common to approach with a top level acceleration structure for the full scene, and bottom level acceleration structures for individual objects. An acceleration structure in this context would usually just be something like an AABB tree or a KD tree. You would cast a ray into the top level node of the tree, and gradually working your way down the tree, eliminating nodes that the ray can't traverse through, until you hit the items in the leaf nodes. The top level structure would store objects, with references to which mesh bottom level structure is used, and the bottom level structures would store triangles. This prevents the ray cast function from trying to compare against meshes well outside of the ray's path, and from trying to compare against triangles well outside the ray's path. For a voxel game as an example you could modify the top level structure to use a voxel grid structure to represent either voxels or chunks. If you're going to be using GPU accelerated ray tracing then you're going to be more limited in how you're allowed to modify the acceleration structure though. Last I checked it was a lot more inflexible.

[@BobzBlue]

@@mettaursp309 I've been thinking about such a technique for a while, however given my lack of experience the only thing I got from your reply was that it would be difficult to give the gpu chunk info (sending stuff to and storing things on the gpu cache or memory is intensive in high quantities). I was really just daydreaming about Minecraft's mesh building for rasterized rendering, the ray tracing used in minecraft probably uses that same mesh and I thought of a method I used in scratch for tiled based collision for wolfenstine styled rendering. It might be a job for a cpu anyway as it requires checking the coodrinates of a ray and reference it to the tile data to detect collision. Maybe the 3d tiling could be equivalent to vertexes, however again, I have no clue whether a gpu could accept such data in any way.

dunno exactly what you're describing but i know teardown's main rendering thing is raymarched voxels, maybe that's similar to what you're describing

[@Roxor128]

Sure. Wolfenstein 3D does the 2D version for rendering, then once it's found the wall intersection, draws an appropriately scaled column of pixels for the distance from the camera onto the screen, followed by appropriately scaled sprites over the top.

You're ridiculously talented at the difficult aspects of game development. I hope we get to see unique game builds from you in the near future. I've been dying to see new focused game projects that utilize PS1-PS2 era designs, art style, etc. ~Even tho Tech has advanced, I wish game companies would alter their approach to gaming. Bring back previous gen games, but they are made in our modern day. Game projects like that will cost less $, take less time to build. We drastically need Additional selection to our game library. We need games that harness art design. Designs that have proven to be timeless. Cell shaded, low poly effects, pre rendered backgrounds, 2D, 2.5D, creative 3D that's not trying to be hyper realistic. Inspiration from previous gens shouldn't stop, just because new consoles have come out. Timeless games don't need hyper realistic graphics. Some of the best games have unique art styles such as Sly Cooper. Anytime i say this someone in the comments always says: "well we have indie games" but that's not my point. I wish the gaming industry would recalibrate their focus & start making games for consoles with all sorts of styles & designs. Just look at current Gen consoles Game Library's? It's NOTHING compared to the N64, PS1, Xbox, GameCube, dreamcast, 360, PS2, Sega Saturn, classic PC games, etc. Life would be amazing If game companies will start making games that are inspired by these previous gen designs. We shouldn't leave those unique aspects of gaming in the past. Hopefully the struggles of the modern triple AAA games will organically transition the gaming industry back towards a better direction. It's exhausting how long it's taking for most games to be made. Just for a lot of those games to end up being total let down projects anyways. It's crazy. Idk how these game companies have been able to keep getting away with this BS. It's devs like you that show real potential and passion in the gaming world

Why use FXAA instead of TAA? As far as im aware FXAA just blurs together pixels on the screen to fake anti aliasing, where TAA does actually calculate the difference between nearby pixels making it look better than fxaa.

[@Acerola_t]

Because it's a game jam and the effort required to use fxaa is zero as I already have it implemented unlike taa

[@th3bigboi]

@@Acerola_t fair enough
