Hitboxes Affecting All Characters With Same BaseID

[ByTheBookGames]

I've come across this problem while testing in 2player mode. If a custom character uses the same baseID as the other player's character, and if that custom character's hitbox and/or offsets are different than the base character, then the other character's hitboxes and offsets are changed as well. I'm trying to figure out how to fix that, if it's fixable.

Here's an example. For a custom character "koopatroopa" that uses baseID 1, if player 1 is koopatroopa and player 2 is mario this happens:


Mario's hitboxes have been unintentionally changed because the character ID "1" has been changed when koopatroopa was loaded.

I've combed through the "playermanager" and "character" scripts (note I'm using SMBX2, not PAL), but it looks like there isn't any way of altering an individual character's hitbox without altering the hitbox of the base character. I'm guessing that creating new baseIDs is impossible because they aren't in the original game, correct? Ideally, I'd be able to have custom characters still use those 5 bases for their physics, etc., but have their .ini files only apply to themselves. I also thought that I could just manually change the height/width of custom characters in their scripts using player.height/player.width, but this wouldn't fix the offsets and it glitches when I try that anyway (changing the height causing the character to skyrocket upwards).

Any ideas on a solution for this? Help is appreciated but not expected. Thanks

yeah 2 player mode with new characters is currently not supported

Thanks for your response. Would you mind explaining a bit of how the custom characters work within Lua? I don't mind developing support for this myself if I have enough direction to work with. Am I right in assuming that custom characters are basically standard characters with graphic changes and extra code? I.e., in the above example, koopatroopa changes mario's hitboxes because in reality they're both mario? There's no way to actually create a new character beyond the original five, which is why custom characters automatically share the same hitbox as the original ones, right?

It's unfortunately not a lua-side issue. It's to do with how SMBX internally handles hitboxes, and yes currently every new character is tied to one of the original five such that they share a hitbox. This is something we're planning to fix in beta 5.

Let me know if this is outside the scope of a forum like this, but how do you go about changing internal aspects of the game like that? This has come up elsewhere in discussions, like changing the input system to allow for more than 2 players. Don't internal changes to the game mess with the memory addresses, too?

The internal changes are mostly done via ASM hooks and C++ code, which patches in the Lua environment. Most of the behavioural changes occur in C++, and since the rest is direct ASM hacking, it doesn't require recompiling the code which means memory addresses stay the same.
