That's not right. You shouldn't just "undo" the whole movement, because part of it was valid, only the amount that went into the ground has to be undone. Hmmm...how would I go about calculating this? As a first project, I know I'm not gonna attempt slopes, so I think it's safe to assume t...

Bumping this because it's already here. It seems like a lot of platform games have the object hotspots at the bottom center to make it easier to land against the ground, but I've already designed my object system around having the hotspot in the top-left corner, and would have to re-write it, so I'd...

Okay, so if I have a switchable bank dedicated to object AI and data, another switchable bank with all the map data for Area 1, and then my collision reading routine in the fixed bank, how would I go about this? 1. In object bank 2. Save the X and Y of where the collision takes place as temporary pa...

Okay, that makes sense. For whatever reason I couldn't get it to work before, but it's working fine now. Thanks, Tepples.

The Programming UNROM article on the wiki is kinda confusing. It says you need to write to $8000 to switch banks, but in the example it looks like it's writing to $C000

Coming back to this. I still don't feel like I've fully grasped how bank switching is properly done, but here's an idea for a ROM map I came up with: Fixed Bank: Main skeleton; NMI handler, reset stub, main loop trampoline Bankswitching routines Camera routines Music engine routines Object system ro...

Speaking of languages, the other day I for whatever reason started thinking about how programming languages would relate to actual languages. Here's my totally unbiased list. Java - Spanish C++ - English C - Latin Assembly - Chinese Python - Esperanto C# - French Lisp - Russian Fortran - German

Even though in programming languages the exclamation mark comes at the beginning, not the end? Maybe he's spanish. In spanish there is a reverse exclamation mark at the begining, and a normal exclamation point at the end. I took Spanish my Freshman and Sophomore year, and have now forgotten pretty ...

Precisely

Reading an exclamatory sentence and thinking the exclamation mark means the sentence is negated.

- no way to reserve sprite 0 for raster effects; Is there really not a way to just advance another prime number when you get to 0? Haven't tested, but something simple like lda oam_index clc adc #76 ;76 / 4 = 19 bne SkipSprite0 adc #76 SkipSprite0: sta oam_index wouldn't work?

Thank you all so much for your help, I really do appreciate it. The engine's certainly come a long way from what it originally was. :wink: I've gotten background collision detection to work with scrolling, but I decided "screw it" and made it so that objects can only have a maximum hitbox ...

And to think I was the only one

I guess this means I'll have yo get rid of my RLE format

After a bit of headache, I've gotten objects to spawn and be deactivated pretty nicely. Right now I have it so that there can be 8 objects that are active at a time, not counting the player, or things that are made by other objects (For instance, projectiles.) For now I've just kept things simple an...
