fwiw you may find this approach to be more practical in some applications

That's friggin' awesome. Now my 18-frame NPC doesn't seem so ridiculous to implement anymore.

Whubwhub!

 

How do I change what the buttons in the teleport menu do? For example, say, when you hover over Egg Corridor, and press Z, it does the whole teleport animation jazz and brings ya there. How would I make it do something else? (Say, play a certain ORG, or teleport you somewhere else) Where is the script that I need to change?

To add a teleporter slot, use the <PS+ command. It's used like this: <PS+XXXX:YYYY where X is the portal slot number being added and Y is the event in the script that gets called when you select that portal slot. So for example, in Arthur's house, when you get access to the Egg Corridor, this happens:

<FL+0153<PS+0001:6001

Flag 0153 is set so that you can check later on in any other script whether or not that portal slot is enabled. And the <PS+ command opens up portal slot 1 and assigns it to event #6001 in the script. If you scroll down to event #6001, you'll see the script that says "Do you want to go to the Egg Corridor?" You can replace that with whatever you want.

 

Balfrog not spawning in modded cave story + (using AGTP story via plus porter)
I've seen at least 1 suggestion of moving data to unmodded game, beat him and then switch back but not sure how to do so

Ah, darn, I just realized that I made that port back before I fixed that glitch with Plus Porter. As a temporary fix, you can delete the stage.tbl file from the folder data\AGTPStory\mod, but that will cause the map names to appear as they do in the NICALiS translation. I ought to upload a version of the port with this glitch fixed. Feel free to give me a prod on my profile or in the Plus Porter thread if I don't get around to uploading a new version of the port within the next couple of weeks.

 

could I cut the file and put it back post balfrog?

 

Theoretically you could, but then you'd probably run into the same problem with Omega, and all the other major boss battles. The issue is that earlier versions of Plus Porter didn't account for one of the properties in stage.tbl that indicated for the map that there was a boss fight, causing this "ID" to default to 0 in all the rooms. So none of the major boss battles will work if you are using the stage.tbl file in the mod. This is a glitch that my testers helped me discover when I was porting my fourth ending mod, but it slipped through earlier ports due to most of them either not using boss battles or not being tested fully.

 

Randolf actually told me how to do this for my mod, so I'll share the process. You're going to need to know how to use OllyDbg at least a little bit.

NOP the entire section from 419EAB to 419EED... And everything from 419f53 to the MOV ESP,EBP.
That fully removes the XP bar...

Every time I try this my game seems to crash as soon as the status bar's shown. I'm editing a clean copy so it shouldn't be any previous mods interfering. What I've been doing is highlighting the sections, right clicking, Binary>Fill with NOPs.
EDIT: Ollydebug also tells me "some debugging features may be disabled" since it doesn't consider me as an admin for some reason. Dunno if that helps.

 

How do I fix backgrounds not being applied to maps? I'm using fullscreen bgs for cutscenes (320x240). My first city one works but my next two dont when i switch maps. Using CE.

don't use CE
no literally, that's it, it's broken

 

CE is actually a lot easier for some people to use. Also, just because it doesn't get updated constantly doesn't mean it's broken. For example, Mario Kart Wii. The online features are gone, and Nintendo doesn't even glance at it, but it can still be a fun game to play with friends or by yourself. An ACTUAL broken editor is Sue's Workshop. Modding with CE isn't nearly as bad as anyone would think it to be. Yes, there is the OCCASIONAL crash, but you should save a lot anyways. I've only experienced 3 crashes in the 3 years I've used it. The only thing I DON'T use CE for is adding maps, for which I am forced to use BL, because CE can't do that (Well it can, but it's extremely hard to do). But I just use edit the maps already there anyways, so it's not a problem. Honestly if someone were to update CE and fix the few major bugs it has, then I'm sure most modders would use it. I myself just prefer using CE for the windows, as I find it much easier to manage.

Same reasons why some people would still use word-filled, detail-less Windows XP GUI over user-friendly Windows 10 GUI. Though updates to CE would be nice, if Wistil made it open-source for others to mess around with.

DON'T use CE for is adding maps

few major bugs

i'm not sure what you're trying to accomplish by whiteknighting cave editor but it isn't going to solve this user's problems

pretty sure it's been open source since forever

Hey noxid
sorry but
maybe the reason why im still using CE is because BL doesn't work with linux and breaks my game when i try to do anything with it

well perhaps now you can find the motivation to submit a pull request on github that fixes those issues

Where can you change how many bullets can be on screen at one time?

I believe this has what your looking for:
https://www.cavestory.org/forums/th...apon-hacking-tutorials-7-weapons-so-far.5240/

 

Theres a bullet limit?

 

for individual weapons there's a function called in the gun code somewhere that checks how many of that type are present
as for the TOTAL limit of all bullet objects, you'd need to rearrange some memory so not as easy

 

ahh still, theon screen data for the seven weapons is there but beyond that....

There's no method of increasing the bullet limit there.

Okay, there's a bit of misinformation here. As well as a universal limit on the amount of bullets existing at a time, each weapon has it own separate maximum bullet values. For example, you can only have 1 Blade thrown at a time, you can only have 2 Polar Star bullets on the screen with the exception of the Spur.

If you want to see how that is done, maybe you should take a look at Critter Tower Defense and Rise of Ballos, two mods of mine. RoB also has an increased entity limit too.

 

I remember someone showed me ASM code for number of bubbles on screen.

Anyway, where should I look for issues when I get the "Failed to read stage" error? The warp ID is correct to me. [Yes GDI im temporarily using a windows pc.]
