Danmakufu Q&A/Problem thread number 4

[Azure Lazuline]

1) Have everything on one stage script, blocking out the view of the character with the menu, and having one task per stage.
2) Your choice. Using Danmakufu menus is ten times easier, but custom menus are more visually appealing and give you more room to work with (unlockable stages and such).
3) If you're wondering how to make a menu with stages work in the first place, don't worry about the small details like that. It's more of a pain than it's worth.

[ふねん1]

I apologize if no one wants to see a "can't start Danmakufu" post here, but I am at a complete loss here. I'm running Windows 7, and I'm starting up the program through AppLocale, but the computer keeps giving me the "th_dnh.exe has stopped working" message. I followed Helepolis' instructions for installing both Danmakafu and AppLocale to the letter. I tried changing my computer settings to Japanese. I tried deleting the Rumia scripts. I double-checked that I had the most up-to-date graphics card. Nothing seems to work, and Danmakufu doesn't get past that first gray window that pops up before crashing. Even the people I talked to on the chat have no idea what's messing this up. So to the others in here, is there anything else I might be missing somewhere that's preventing the game from starting up?

-Try opening the game through config.exe. The left-most button starts it. Applocale, etc.
-Try a different th_dnh.exe.
-Restart computer.
-Post screenshot of folder and error details if possible.

[ふねん1]

Tried your config.exe suggestion, and it got to the main menu! Never knew I could open the program like that, especially since the button was written with all question marks and I couldn't read it. Thanks for the help.

Has anyone noticed some strange stuff with bullet deletion for CreateShotAs ?

Normally danmakufu handles the fieldboundaries + some pixels as the auto-delete area for any bullet travelling beyond it right? (excluding obj bullets which cannot be destroyed)

When I test my spell card solo, the bullets that leave the screen disappear. How ever if I test the same card during my stage the bullets return back into my screen, stacking up each time. I don't remember putting any code altering the bullet deletion in my stage script. I simply made a curving CreateShotA pattern where bullets being spawned, travel forward while curving and surely leave the screen enough to be actually deleted. Guess what, they return after like 4-5 seconds of travelling.

Don't ask me to post code because it has no use to post 2000 lines of code. So what is going on?

It's just Danmakufu being Danmakufu, I guess. For a simple fix, you can try manually setting the auto delete clip with SetShotAutoDeleteClip in the spellcard itself, or in the stage. It seems to default to 64 for all 4 sides according to the wiki, but perhaps that's only in some cases. Maybe mkm screwed up and didn't make the defaults the same in all cases.

(Also, shot objects DO get auto-deleted unless specifically told not to with Obj_SetAutoDelete(obj, false).)

[Helepolis]

I see you got Jazz Flandre as avatar.

Also that indeed fixed the problem. I didn't knew SetShot(ry was saved in Danmakufu memory. If you call it only once in a previous boss/spellcard it will affect the entire game. My afro boss increased the boundaries of SetShot(ry by 300 pixels. orz

So I've been looking through the basics and the first  little bit of the intermediate tutorials, and I'm used to the general CreateShot commands and all that stuff.
And I'm wondering why this isn't working:

Code: [Select]

#TouhouDanmakufu
#Title[Attack Name]
#Text[Attack Description]
#BGM[.\bgm.mp3]
#Player[FREE]
#ScriptVersion[2]

script_enemy_main {
    let frame = 0;
    @Initialize {
        SetLife(1000);
        SetEnemyMarker(true);
SetTimer(60);
MagicCircle(true);
SetMovePosition02(GetCenterX, GetCenterY - 100, 120);
    }

    @MainLoop {
        SetCollisionA(GetX, GetY, 32);
SetCollisionB(GetX, GetY, 24);
        if(frame==5){
            CreateShot12(46, 40, 10, 2, -0.5, 1, -20, 10, RED01, 10);
    CreateShot12(400, 40, -10, 2, 0.5, 1, 20, 10, RED01, 10);
    frame = 0;
frame++;
}
if(frame==20){
    CreateShot01(GetX, GetY, 3, GetAngleToPlayer, GREEN01, 10);
            frame = 0;
frame++;
        }
    }

    @DrawLoop {       
    }

    @Finalize {
    }
}
I'm trying to get the RED01's to fire on different frames than the GREEN01's, but niether of them spawn when the script runs, no errors though...
I thought I might have to use alternative/case, but the same nothing happens (though I don't know if I've done this one right...).

Code: [Select]

@MainLoop {
        SetCollisionA(GetX, GetY, 32);
   SetCollisionB(GetX, GetY, 24);
        alternative(frame)
   case(5){
            CreateShot12(46, 40, 10, 2, -0.5, 1, -20, 10, RED22, 10);
       CreateShot12(400, 40, -10, 2, 0.5, 1, 20, 10, RED22, 10);
       frame = 0;
   frame++;
   }
   case(20){
       CreateShot01(GetX, GetY, 3, GetAngleToPlayer, GREEN22, 10);
            frame = 0;
   frame++;
        }
    }
The two separate shots work fine on their own, but I don't know how I'm supposed to get them to work together.

[ChiyuriKitashirakawa]

This is sorta silly.
Is there a way to make familiars have more complex movement than shooting them like bullets? I mean, I have some movement scripts on the familiar enemy script,  but they do nothing.

[Chronojet ⚙ Dragon]

So I've been looking through the basics and the first  little bit of the intermediate tutorials, and I'm used to the general CreateShot commands and all that stuff.
And I'm wondering why this isn't working:

Code: [Select]

snip

Of course it doesn't work.
The variable "frame" doesn't increment until it has a value of either 5 or 20. Which you never actually make happen.
Fix: put one of the frame++; just after @MainLoop { and delete the other one.

Like so: (i also fixed some teensy "errors")

Code: [Select]

    @MainLoop {
frame++;
        SetCollisionA(GetX, GetY, 32);
SetCollisionB(GetX, GetY, 24);
        if(frame%5==0){
            CreateShot12(46, 40, 10, 2, -0.5, 1, -20, 10, RED01, 10);
    CreateShot12(400, 40, -10, 2, 0.5, 1, 20, 10, RED01, 10);
}
if(frame==20){
    CreateShot01(GetX, GetY, 3, GetAngleToPlayer, GREEN01, 10);
            frame = 0;
        }
    }

SetX/SetY? Obj_SetX/Obj_SetY?

[ChiyuriKitashirakawa]

SetX/SetY? Obj_SetX/Obj_SetY?

I thought of those, but I'm not sure if they can create smooth movement.

[Drake]

task moveshit(angle,speed){
    loop{
        SetX(GetX+cos(angle)*speed);
        SetY(GetX+sin(angle)*speed);
        //change angle maybe
        //change speed maybe
        yield;
    }
}

Something like that.

fixed code stuff

Thanks for fixing that. Just one question about the fixed one though, what does the "%5==0" in "if(frame%5==0){}" mean? I noticed it doesn't work at (frame==5), which I originally thought would work...

[Drake]

x%n is the denotation of "x modulus n", where the value is the remainder of x/n (or rather r in the equation x=y*n+r). For example.

3%10 = 3
6%10 = 6
9%10 = 9
10%10 = 0
11%10 = 1
12%10 = 2
40%10 = 0
129641%10 = 1
5%3 = 2
72%3 = 0
6001%3 = 1
80%7 = 3

So when you say if(frame%5==0), you mean you want to execute that code every time frame is a multiple of 5. Since MainLoop runs every frame and you increment frame by 1, every 5 frames that code will execute.
If you just say if(frame==5), the code will execute after 5 frames and then never again unless you reset frame to 0 or somewhere below 5.

[Helepolis]

About the familiars as well: You can use Drake's code for smoother movement or just use SetMoveSpeed03. Many flavours available ze.

Ok, that makes more sense.

Hi,I wondered how to shake the camera in the script version 2,because i can't seem to get it to work well... Also, a friend of mine gave me this:http://www.mediafire.com/?ve8r1y22kpykdny  It has pretty nice things though where could I find the necessary resources?Because they look awesome,thanks already~

Shaking the camera is technically impossible with script version 2. The best thing you can do is shake the enemy graphics, the background, the player, and all the bullets (which will have to be shot objects) at the same time with some special set up. I actually wrote something like this before but I lost it. If you are new to Danmakufu, I highly advise to just forget about shaking the camera. It's just an aesthetic thing anyway.

For your second question, I"m not entirely sure what you're asking. If you're asking where to find graphics for your own projects, you'll just have to ask someone to create them for you. However, very rarely will anyone actually help out unless you show them a nearly finished product that just needs graphics. You can always use placeholder images or even steal ZUN's images to use. Of course, the Japanese community doesn't really approve of using ZUN's graphics, but over here we don't really give a damn.

[BrawlerGamma]

So, like, it opens, it runs, then when I press "Single," "All," do to Direction and try to load a script... try to change the script type... it always crashes no matter what I do.  Does anyone know what might cause this and how/if it can be fixed?  Thank You.

[Mr. Sacchi]

Applocale, pretty much.

[BrawlerGamma]

That's all? I tried to get that and it failed to install... 5 times... and I ran it, and it ran (sort of), so I assumed it was fine without.... Guess not, eh?

[Mr. Sacchi]

When trying to do anything with japanese things, touhou fangames and danmakufu included, run with applocale, it's pretty much the "ultimate fixer", and I say that from experience *Glares at Genius Of Sappheiros*

[BrawlerGamma]

There we go. Thanks for the help, took a minute figurin' out why the stupid thing wouldn't install right, but it's workin now. Thanks for the help.

[MarielSaen]

Can somebody help me on Danmakufu? I don't know where to get picture files for the characters compatible with Danmakufu, and I don't know what every bit of the code to make the game represents.

[Stuffman]

Oy.

I don't know where to get picture files for the characters compatible with Danmakufu

DMF uses regular GIFs and PNGs (and possibly BMPs but there's no reason to use those).

I don't know what every bit of the code to make the game represents.

Read the tutorials.

If you don't even tell us what you're trying to do then how are we supposed to help? At least TRY to write some code so we can tell you why it's not working. This is the laziest help post ever.

[Iryan]

Not to mention there is an actual Q&A thread...

[Romantique Tp]

Does danmakufu have some standard for spritesheets ? Note that I don't know shit about danmakufu, but I'm thinking about making some "free" spritesheets for practice. (I haven't sprited in a while...)

[Drake]

png
transparent background is transparent for alpha blend, pure black (0,0,0) is as well, do not use black background for alpha blend if the image is not perfectly opaque
black bg is transparent for add blend as should be obvious, transparency draws as white so don't do that

[Serina]

Well, i don't get it. I checked and all the { and }'s are okay. I tried just to add a { in the DrawLoop and it asks me to add a }. I tried also adding some random {{{ and the script ran, but there was only a hitbox, i was invincible (that's okay because my Missed loop is empty there's only the yield;) and i couldn't shot.
What can I do?
