Quick Modding/Hacking Answers Thread

Hi, I've searched but I'm still confused as to what are Option 1 and Option 2 in the entity flags in Cave Editor. Do they control what direction the entity is facing? Do they make the trigger horizontal or vertical? I have no idea >n<

 

They do various things. In Booster's Lab they would be the called“Spawn with alt direct option”. Anyway, let's take a H/V trigger for example: it's set up to be horizontal by default, BUT if you use option 2 it'll become a vertical trigger. Very cool. By the way, the ultimate editor is Booster's Lab, so if I were you I would use that one.

 

oh, I see! What else can they do?

 

As you mentioned they can also change the direction of entities and such, but I'm pretty sure they have many, MANY other functions regarding other types of entities.

 

okay, thank you very much!

 

Yeah, Option 1 and Option 2 are dumb names.

Here's the entity flag names used in Booster's Lab for reference (I initially thought those can just be plugged into the CaveEditor.txt file for Cave Editor, but there's defines for them in there, hacking may need to be required).

0x0001 Solid (bouncy sides)
0x0002 Not Affected By Tile44
0x0004 Invulnerable
0x0008 Ignore Solid
0x0010 Bouncy Top
0x0020 Shootable
0x0040 Solid (hard sides)
0x0080 Rear and top no damage
0x0100 Run event on contact
0x0200 Run event on death
0x0400 (Unused)
0x0800 Appear once flagID set
0x1000 Spawn with alt direction
0x2000 Interactable
0x4000 No Appear if flagID set
0x8000 Show Damage #

 

ooh, ok. Thanks!

 

Okay, I've made a modded version that fixes the Entity Flag dialog in both the map editor and in npc.tbl, so there won't be anymore further confusion between Cave Editor users and Booster's Lab users.

Hello, I'm having problems with my mod. To me it works fine but to others not. According to the error log, PrtCave.bmp and NpcSym.bmp are returning 1 instead of 0. The characteristic these two share is that I edited them with GIMP (GNU Image Manipulation Program), but I've also edited PrtMimi.bmp with GIMP and this file still returns 0. I'm using CEditor and not using CSE2. I have also actually used the edited tiles of PrtCave and NpcSym in maps, but not the edited tiles of PrtMimi. Here's the download link.

Ahah, here's the problem. You using GIMP! You know what they say, all toasters toast toast!

I'd suggest any other image editing software, GIMP is always the source to "my Cave Story bitmaps are broken!". Paint.NET, FireAlpaca, or Aseprite are often recommended.

ah ;-; that's a pity, I love GIMP.
Thank you very much!

 

Booster's Lab is giving me a headache because apparently it has something against Ubuntu users.

Spoiler: oh it says BkBlue has to be bkBlue? ok let's go and change the name

Spoiler: ok let's see if- oh COME ON

ik it's like my third question in a row but i am Mildly Frustrated, can someone help please?

Edit: Thanks to the modding discord community I was able to solve the problem!

 

How you edit the credits?

 

How you edit the credits?

There's a guide for that in Booster's Lab.

 

...i'm not sure why you're asking here, on a long dead thread for my kinda mediocre first mod of all places, but yeah. booster's lab's help section has a guide on how to edit the credits, it's not that tricky once you get the hang of it.

I will try another time, make the Booster's Lab work.

EDIT: I got it, thanks!

 

So regarding Entity #20 (Computer), it has 3 different sprites that I redesigned for the Mechanto Gate in Gun v2. So considering that Entity #20 has 3 different sprites, can you switch between them with ANP?

Probably not. Especially when the computer entity doesn't have an animation table of it's own. You'll have to write one in with ASM.

If that's the case, then I'm under the mistaken assumption that the computer sprite is animated considering it has 3 sprites. So what are the three sprites actually used for?

Spoiler: Original CS Computer sprites

Spoiler: Gun v2 Mechanto Gate

 

Looking into the assembly, the sprites are all looped depending on direction. One just happens to be in a one frame animation and one happens to be in a two frame animation. However, neither are dependent on <ANP, nor is there code like JMP DWORD [E_X*4+4XXXXX] in the NPC. There isn't even an animation table at the end, the code just jumps straight to NPC 021.
