The most polite way I know is the full "domo arigatou gozaimasu", which is a bit of a mouthful. I have never heard shimasu used with it, but really I don't know it well enough to guarantee that it's incorrect.

To be honest, I trust you more. I learned most of my Japanese (which is barely any) from online lessons, most likely including "thank you". I started Rosetta Stone afterwards but got sidetracked...

Where is the blue Quote's sprite located? Did you just redo an original sprite (Quote, maybe)? That's probably the case, but if you put the sprite in a new spot, that would possibly cause trouble. Also, if you happen to know where the <null> sprite is located, you can always check that spot to see if blue Quote is there. I don't have much know-how of all of this though. :/

EDIT: Oh, and make sure you didn't change the overall size of the sprite, unless you were able to counteract everything it pushed.

I just edited the original sprite. It's located at the same point I believe. I don't know where <null> is. Actually, I've never known there was one. I didn't change the size.

Yeah, the invisible square. The problem is that it just doesn't. I'm gonna edit something first in a different Doukutsu, and get back to you.

It's a TSC event, <AIRXXXX. It stores current air to EDX, finds the first parameter and stores it to EAX, MOVs 0A (10 in decimal) to ECX, multiplies EAX by ECX, and MOVs ECX to EDX. This should make the TSC event <AIR set the player's current amount of air, but it just freezes. Does anyone see the problem?
Oh, and the JMP SHORT at the end is because there's a load of NOPs after it.

Well, the problem I see is that you never store the result EDX back to the memory location [49E6DC].
You need to do:

MOV DWORD PTR DS:[49E6DC],EDX

right after MOV EDX,ECX.

If [49E6DC] is a box that I can put numbers in, then doing MOV EDX,DWORD PTR DS:[49E6DC] does not store the "box" into EDX. It just stores the number hidden inside the box into EDX. Basically, you stored the current oxygen (the amount of oxygen) into EDX, got a result, and threw the result away. To fix it, save the result by MOVing EDX back to the oxygen offset.

Also, you probably don't need all those MOVs. The basic goal is:

Multiply the number in EAX by 10. (EAX holds the first parameter)
Store that number to the current oxygen.

This is possible in 2 instructions:

Code:

CPU Disasm
Address   Hex dump          Command                         Comments
00424EFE  6BC0 0A       IMUL EAX,EAX,0A                 ;Multiply EAX by 10, store back to EAX.
00424F01  A3 DCE64900   MOV DWORD PTR DS:[49E6DC],EAX   ;MOV EAX into [49E6DC]

Now, since your game is freezing, I'm not exactly sure why. I'd have to test the code first.

Slither · Jul 14, 2011

Thanks. It still freezes, though. I can PM you the file if you want.

GIRakaCHEEZER · Jul 14, 2011

Check your jumps. Jumps are almost always the problem.

Slither · Jul 14, 2011

The jmps, eh? Well, the JMP 424F33 jumps to the next TSC command thing. The JMP SHORT 424F2E jumps to the JMP 4252A7 jumps to the beginning of the parser. They should work. Even when I take out the JMP SHORT it freezes.

GIRakaCHEEZER · Jul 14, 2011

You could always try running it through ollydbg to see WHERE it's freezing.

Slither · Jul 14, 2011

I did, but carrotlord helped me out. Apparently I was missing a vital TSC command part.

Lace · Jul 14, 2011

Yes. You didn't add to the tsc pointer (where you are in the code), so it kept running the same command over and over and over.

What the hell is wrong with this? I'm trying to have a Balfrog fight.
The things I changed (compared this to the script in Boss Rush):
Direction and location of the player and boss
Text in the messages
Removed flags that were for other non-included events
Changed map tileset to Oside
Balfrog's event number (I made sure to change each and every one in the script)
The music...

Can I not change the tileset? The special boss script and the NPC tilesets were all unchanged (2 - Balfrog, Frog, and Weed respectively). Can I not change its direction? It seems rather arbitrary.

Slither · Jul 15, 2011

Well I don't think balfrog is a special boss, so it wouldn't be <BSL0000. I'm pretty sure <BOA is useless; you can just use <ANP. After a <MSG<TUR, you need <NOD AND <CLO. <NOD only checks for a key; it doesn't close the message box.
And if you want #0201 to show up after balfrog is defeated, make sure balfrog's event # is 201 and "run script upon death" flag is checked.

Did you change the special boss part in the settings to Balfrog? And I don't think you can change the direction unless you use assembly.

Slither · Jul 15, 2011

Huh, I guess it is a special boss. Silly me!
Hey, does a special boss play a specific event upon death?

Well, Balfrog is listed under the special boss scripts thing in Map Properties and the original Balfrog fight had the exact same <BSL and <BOA functions, so I kept them untouched. As far as <CLO goes, the original didn't have that either, and when I test the fight, it indeed closes itself. The boss just doesn't appear. The message box closes, the Boss health at the bottom appears, but the boss just doesn't exist; not interactive or visible.

EDIT: Apparently, special bosses have fixed spawn locations, so I will return it to its rightful location and see if that fixes the problem.

Slither · Jul 15, 2011

Now I'm caught up.
Special bosses appear at a certain place on the map, since you can't pick a place manually. That's why balfrog is in a small map. It has to be the same arena size as the original, but you can do what you want in there. I suppose you can increase the size, but just make sure the player is in the area where the boss appears when it appears.
