Quick Modding/Hacking Answers Thread

(I'm on mobile so hopefully this is worded right and helps)

2 problems:
1st problem: It wouldn't be the damage function actually. NPCs don't continually check player collision and then run that function from what I've seen. Instead it just has a variable of how much damage should be dealt on contact (this is in the NPC table, so ALL npcs have one). There's seperate generalized functions that check collisions for the NPCs and will calculate that etc.
This variable is expressed as "E?X+A4" in the NPC's code. You'd be changing the constant in an instruction that goes something like

MOV DWORD --?-- [E?X+A4],###

where ### is the damage.

2nd Problem: Balfrog (as is most mapbosses) is actually composed of seperate sub-entities with different hitboxes. iirc there's two that both deal damage.
You can find the offsets towards the end of this sheet. (This link is also pinned in CSMC's #resources.)
Looks like Balfrog has 3 entities (one of them being the main one that Hayden gave you the offset for). And your gonna change any E?X+A4 constants you happen to find like I mentioned earlier. That should do it!

 

Some maps have no background in-game, despite the map properties being set.
(And in one case, at least one map that did have a background in-game, suddenly stopped having it.)

Is there any way to fix this, and if so, how?

Depends on these two factors.
1. Is the background type set to "Hide"?
2. Are you using Cave Editor and are making maps past room 94?

 

Only three maps using the Water Level entity are set to "3 - hide". (Though the water doesn't show up on one map, despite showing up on the other.)

Yeah, I'm using CE (with maps numbered to 099).
I'd use Booster's Lab 0.4.5.0 but I can't place entities in that (I'm guessing that's an issue on my end that can't currently be fixed, due to circumstances) so... kinda stuck with CE here. :/

 

In v450 and above, you need to press the "i" key, cuz double clicking really resulted in quite the number of bugs. I do suggest using BL v500 since that's the most stable version (and v511 really has some issues that have been reported to Noxid and Leo and not a single fix was made).

Try either doubleclick lmb or the i key.

 

my friend wanted me to convert his freeware save to cs+ but its in normal mode and he wants it in easy mode
how would i change it

 

nvm its at c30 in hxd and changed 00 to 02

 

This is my fist time modding and I would like to know how to do a few things in Cave Editor
1. How do I change Quote's Sprite ( I can't find it)
2. How do I get a working door transition with a music change
3. How do I do a door and key System
4. How do I change the Title and the intro ________Presents

1. data/MyChar.bmp (make sure to save as 24-bit bitmap to keep the changes without the colors fucking over)
2. You can copy/paste the TSC for the events in the scripts to help give you an idea on how it'll work.
3. You can use <ITJ (ITem Jump) to jump to an event when you have whichever item is necessary. Otherwise, you won't be able to access the next room.
4. Title:

Spoiler: Title

Spoiler: Title screen, if that's what you meant

Just be sure to modify Title.bmp if you decide to make it full-screen. If you don't wanna touch the config, then you can just modify the bitmap.

Ok thanks I found a program to edit sprites called pixelformer to change the title and characters, and I will try reusing code for existing doors.

 

How do you change the backround on the title screen? Don't tell me you can't because I've seen it.

 

That's done via assembly hacking. There's a specific assembly hack that does that called the Title Screen Hack. It's even built into Booster's Lab. If you go to "Actions" -> "Hacking Tool", then select "titlescreen," and then it will patch the EXE with this hack that lets you have a custom image on the title screen.

now what.

--Edit--
@HaydenStudios Ya there? anyone?

 

Open up "Title.bmp" in the data folder. By default, the game extracts the title screen a framerect in that image with the top-left corner of (0, 0), and a bottom right of (144, 40). You'll probably want to edit "Title.bmp" to have your full image in the top left region of the image, and change the bottom-right X/Y framerect values to 320/240, respectively. The "X Render Position" and "Y Render Position" defines where the title image will be drawn. For your purposes, I'm guessing you'll probably want to change these both to 0.

I'm guessing that the graphics for the "New" and "Load" buttons will need to be placed directly to the right, outside of wherever you set the framerect for the title screen.

Once you've changed those values accordingly, you should be able to patch in the hack by clicking "Commit!"

you still make no sense but ok.

 

What part in particular doesn't make sense? Are you familiar with what framerects are? If this was confusing to you, I can make a picture that illustrates what fields in that Booster's Lab hack relate to what properties of the title screen.

 

I'm guessing that the graphics for the "New" and "Load" buttons will need to be placed directly to the right, outside of wherever you set the framerect for the title screen.

Actually, you can just draw the new ones in the title bitmap itself, especially since the "Don't Draw New/Load" option is there, and there is no setting to assign new framerects for those, anyway. Of course, you can also just have the origin for the title screen framerects be offset more vertically down for the bitmap, and keep the New/Load symbols intact.

 

ok then do the pictures i guess @HaydenStudios or @Serri

 

Okay, let me know if this helps:
