I'd say this video is 2 epic guys colliding (for the 2nd time), but you don't have collisions working very good yet :)

@sukus 9 месяцев назад

In order to solve the layering issue without taking up too many background layers, you could try re-drawing the parts of the player that SHOULD be above the terrain!

@SomeRanDev 9 месяцев назад

Tragically this is not possible on the Gameboy Advance. Images are loaded as preset 8x8 tiles (or powers of 2 from 8 -> 64 for sprites), and there's no support for cutting off sprites. 😭 At best I could hide certain 8x8 blocks on the player sprite, but nothing as complicated as the diagonal tiles. (Though... you can allocate and manipulate VRAM directly on a pixel by pixel basis, but doing in every frame isn't feasible with GBA performance, especially for multiple entities.)

@sukus 9 месяцев назад

@@SomeRanDev hmm... Would it be possible to do it the other way around? Drawing higher-priority parts of the background with sprites? Those are already 8x8 aligned! Or does the GBA have seperate tables for sprite- and background graphics?

@SomeRanDev 9 месяцев назад

That's actually a really interesting idea. Since the GBA has a relatively small sprite limit, would need to be smart so it only generates sprites for the tiles the player (and other entities) are directly under, but hypothetically could be done.... except as you mentioned, not sure if background tile resources can be used by sprites. In Butano they're stored as different assets, so I'll have to investigate!

@sukus 9 месяцев назад

@@SomeRanDev Accodring to the GBAtek hardware documentation (which I cannot link, RU-vid keeps marking it as spam), sprites and background tiles are located in different parts of VRAM unfortunately :(

Also the outline effect looks nicer. 😅)

@asphegames 9 месяцев назад

Very cool! I made a pixel perfect collision system by having a tileset for pixel collision data. Each pixel of a collision tile essentially encoded a precalculated push vector and other relavent collision information (wall, ladder, stair, etc).. To see if a collision occured I just had to see if a specific pixel encoded a push vector.

@Kio_Kurashi 9 месяцев назад

Imagine if for the tile map layering where the gras was appearing over the character that you instead didn't have grass afixed to the wall sprite. But that'd be kooky. And we _totally_ can't do kooky on only a handful of layers.

@SomeRanDev 9 месяцев назад

Even if the grass wasn't affixed... the player would still clip into walls? (Like at 10:03). But yeah, I agree! It would be a bit kooky to waste multiple layers on a common tile pattern that could just be drawn as a single tile from the start.

@hypermodel8964 Месяц назад

Tiles for the lowest parts of walls will never be required to be drawn over the top of the player, so there's no reason to not have those tiles sent back to the "floor" layer. Emulation issues show this was done with tree tiles in the Pokemon GBA games, where emulators have a hard time drawing a mist/fog overlay over everything so any "foreground" tiles get excluded (and you see tops of trees poking out of the fog)

@CaptainBeebi Месяц назад

The collision system reminds me of what the GBA Pokemon games used for its height&collision map. Have 0x0C for default passable, 0x10 for elevation 1 passable, 0x00 to transition between levels, etc. Was a really clean system to work with, even years before the G3 decomp projects began when we were all running blind through the ROM files. Funnily enough, I'm actually working in the opposite direction as your project, porting a GBA game to modern systems, so I've been seeing a lot of the BS you must be dealing with in the original game's source repository lmao.

@iLgaming334 8 месяцев назад

apologies as I have never developed for the GBA but have you thought about Y-sorting? it should give you both the ability for the player to be able to be layered both infront and behind the tileset. Essentially: you'd need to track your player's feet position and compare their Y position to the one of the relevant tiles. If the Player is below the tile (as in y coords) it will be layered above the tileset and the player should be layered below in the reverse case.

@Natzawa 3 месяца назад

I doubt you’ll see this. Not sure if you would even update it. But, I noticed the SRD HUD Maker for MV will slow down the game when you have less than 4 characters in your party. It’s even worse with 1 character as the FPS drops from 120 to 30. It’s not a plugin conflict issue either. It’s causing errors in the HUD boxes when theres no other party members. Was wondering if you could take a look at it? Would much appreciate it.

@Natzawa 3 месяца назад

For every party member there is the FPS goes back up. Just tested this on a fresh save file just to double check to make sure plugins weren’t the issue. My conditionals are setup correctly since it works perfectly with 4 players and I don’t drop FPS.

But your videos got me back into messing around with the idea of making a game or maybe working on a new project. Oddly enough you inspired me to actually start a new project. 😌 Maybe not a game, but at least something other than just working ans warching vidoes 😄 games tend to be more work than robots tbh, since i dont like using engines with editors 😄.

Since there are 4 layers available(and 4th I asume is used for HUD) maybe one could use 3rd layers just in the problematic spots?

@NoelleBaba 8 месяцев назад

There are probably limitations or downsides I'm not thinking of, but would splitting the player sprite into segments and checking the layering of each segment individually fix the layer issue? If the bottom half of the character is rendered below the layer, but the top half is above, that should allow them to appear between objects, right?

@Veecy 8 месяцев назад

Wow, this is coming along really nicely. In the beginning, why not just build a custom GBA emulator to run the PC version of the game, similar to the Virtual Console?

@SomeRanDev 8 месяцев назад

I plan on having a PC-focused devlog eventually to answer this question, but long story short I want the PC version to be the best game it can be without adhering to GBA restrictions when possible, for example: 1) Be higher resolution, zoomed out, see more of the map, etc. 2) Have different in-game options like keyboard or controller bindings AND better accessibility options that wouldn't be possible on GBA 3) Smoother gameplay, use transparency in places where the GBA cannot 4) Port to modern consoles perhaps???
