Danmakufu Q&A/Problem Thread II

[Iryan]

You have to add the child shot before you fire the main shot. This is important.

[Helepolis]

The only possible explanations for me would be that
a) #include_script doesn't work in child enemies, or that
b) you cannot call #include_script in the same file more than once, even if it is in separate script_enemy parts.

Where are you calling this include_file? Inside the stage or the spellcard itself?

Because, I am calling included scripts from the same file ( spellcard with familiars ) and even some files twice. Script_Enemy  are considered separate from Script_Enemy_Main and there for should not collide with each other.

I don't know what exactly you are trying to do, but technically calling stuff should be possible. Please elaborate more

Example how I have a spellcard:

Code: [Select]

script_enemy_main {
    #include_function "script\DanceContest\functions\systemloader.txt"
}

script_enemy shaker{
    #include_function "script\DanceContest\functions\superfams.txt"
}
(systemloader is basically including 5 scripts at once, which superfams is one of those scripts. So technically I am calling the same file twice here and no errors. So there is something that Danmakufu does not like when you are calling it twice.)

[Iryan]

I am calling the #include_script at the beginning of the script_enemy{} portions outside the @ parts. Afaik, that's where one is supposed to define variables and tasks relevant for the entire script.

Code: [Select]

#TouhouDanmakufu
#Title[New Test L New 3]
#Text[Test]
#Player[FREE]
#ScriptVersion[2]

script_enemy_main {

#include_script ".\add\Filename.txt";

<snip>

}
//---------------
script_enemy CLONE{

#include_script ".\add\Filename.txt";
<snip>

}The boss enemy then creates one child enemy in the @MainLoop when the ever-increasing timer variable frame reaches the value of -120.

[Helepolis]

That is odd, outside the @ blocks is what I do as well. That should work. =|  Can you show the content perhaps of your  include_script?

[Iryan]

Nothing too troublesome, it worked perfectly fine in all previous scripts afterall. Just some variable and task definitions for animation, and a movement function definition. None of the variable or task names are used to name other things in my scripts.

Code: [Select]

let img_trail= GetCurrentScriptDirectory ~"add\Trail.png";
let img_sword= GetCurrentScriptDirectory ~"add\SwordTest.png";

let animate=0;
let animate_sword=0;
let animate_attack=0;


function rush(distance, time, bleft, btop, bright, bbottom){

let doit=0;
let angle=0;
while(doit==0){
angle=rand(0, 360);
if( GetX+distance*cos(angle)>bleft
&& GetY+distance*sin(angle)>btop
&& GetX+distance*cos(angle)<bright
&& GetY+distance*sin(angle)<bbottom ){ doit=1; }
}
SetMovePosition02(GetX+distance*cos(angle), GetY+distance*sin(angle), time);

}

task GhostWisp{

let visibility=128;
let size=0.5;

let obj=Obj_Create(OBJ_EFFECT);
Obj_SetAlpha(obj, visibility);
Obj_SetPosition(obj, GetX+rand(-10,10), GetY+rand(10,25));
ObjEffect_SetTexture(obj,img_trail);
ObjEffect_SetRenderState(obj, ADD);
ObjEffect_CreateVertex(obj, 4);
ObjEffect_SetPrimitiveType(obj,PRIMITIVE_TRIANGLEFAN);
ObjEffect_SetLayer(obj, 1);

while(Obj_BeDeleted(obj)==false){

Obj_SetY(obj, Obj_GetY(obj)+1);
size=size*0.98;
visibility-=2;

if(visibility==0){ Obj_Delete(obj); }

ascent(i in 0..5){
ObjEffect_SetVertexColor(obj,i,visibility,255,255,255);
}

ObjEffect_SetVertexUV(obj,0,0,0);
ObjEffect_SetVertexUV(obj,1,21,0);
ObjEffect_SetVertexUV(obj,2,21,29);
ObjEffect_SetVertexUV(obj,3,0,29);

ObjEffect_SetVertexXY(obj,0,-11.5*size,-14.5*size);
ObjEffect_SetVertexXY(obj,1,11.5*size,-14.5*size);
ObjEffect_SetVertexXY(obj,2,11.5*size,14.5*size);
ObjEffect_SetVertexXY(obj,3,-11.5*size,14.5*size);

yield;
}
}

task GhostTrail{

LoadGraphic(img_trail);
LoadGraphic(img_sword);

loop{
yield;
GhostWisp;
}

}


task TSwAnim(t1, t2, t3){

loop(t1){ animate_sword+=164/t1; yield; }
loop(t2){ yield; }
loop(t3){ animate_sword-=164/t3; yield; }

}GhostTrail is usually run in the @Intialize. In my child script I ran GhostWisp manually in the @MainLoop once the @Initialize has passed, so I neither load the graphics mulitple times, nor am I creating an EffectObject in @Initialize.

I don't think there is any content here that could cause these problems...

[Helepolis]

I am confused =|  I don't see anything odd indeed. Assuming you are saying it worked all fine before in your scripts. I think you should apply trial and error here. Make backup, disable all functions/tasks you are trying to achieve and enable them step by step untill you hit the task/function/code that causes the error.

Aside from that I seriously don't see anything weird here except some doubting about GhostTrail but I don't know how it is all bound together with your main scripts.

[Iryan]

I copypasted the exact same line I used in the main script where it works just fine, and if the filename was invalid danmakufu would spit out an error about this, which it doesn't. The script's existence is acknowledged, yet the script is not included.

However, if I delete the #include_script and every reference to its data from the main enemy, the #include_script works just fine.

If I make a text file that has no other line but the #include_script, then include THAT script, it still tells me the stuff is not defined.

If I copy the script and call #include_script on the copy, which is identical except for the file name, everything works.


Conclusion:
Danmakufu doesn't recognize a repeated #include_script command, even if it is repeated in an entirely different section of the script.

*facepalm*

But hey, the script works now, so screw this nonsensical limitation. Now to tinker with that spell card...

=.= Oh god what? FFFFF. At this rate we need another thread called: "Weird fucked up things Danmakufu does not like".

Last time I was raging hard why my EnemyMarker would not show up on IRC. Then someone said to reverse the order of MagicCircle and SetEnemyMarker.

Example:
   MagicCircle(false);
   SetEnemyMarker(true);
Shows no magiccircle, but shows marker. But if you somehow write it like this:

   SetEnemyMarker(true);
   MagicCircle(false);
It will show no enemy marker at all.

[Azure Lazuline]

Setting MagicCircle(false) automatically turns off the enemy marker, so since you set the marker beforehand, it turned it off. Still stupid, I know, but at least there's a reason.

[Helepolis]

There is no reason. They use different textures even. Danmakufu is just stupid as hell :V I was seriously raging hard until you told me to swap them.

[Demonbman]

Ok, I am having issues with my stage code, in plain terms, the folder is set up like this"
Prisimriver\Lyrica\Lyrica.txt

But Lyrica.txt is a plural, which contains:
Lyrica 01.txt
Lyrica 02.txt
Lyrica S1.txt
Lyrica 03.txt

And each contain Data.txt which is called in each Script, via #include_function,Data.txt is located in the Prisimriver main folder, as is the Stage Script.

The Problem is that when I run the stage, it crashes saying that there is an error with Data.txt, but it works fine in the Single Files, and Crashes in the Plural file, its strange....

[Blargel]

If it works in the Single files, there's nothing wrong with the single files, what does your Plural look like? Perhaps you're doing something strange there. Post up the plural and I'll take a look.

Also, about your code block problem how it mangles your code's spacing and line breaks, what operating system and what editor are you using? If you're on Windows and using NotePad++, you might be saving your files in the wrong format. Go to Format -> Convert to Windows Format and everything you copypaste from there should have line breaks in the correct place again outside of NotePad++.

Note how the flower centers release around six "spores."
Strangely, I don't believe I have any loop that would make them release six. Rather, each flower should only shoot one.
Like I said before, the end result is pretty tolerable. I should be able to just loop my CreateShot01 twice to get 12 spores per flower, which would be more ideal in the spellcard, but... It just wouldn't be right. Could someone explain why this is happening?

[Blargel]

Code: [Select]

         loop(6){
            Petal(tr_ang, ang, 20, 1, YELLOW02);
            FlowerCenter(tr_ang, ang, 20, 1, GREEN05);
            ang += 360/6;
         }

Found in your Flowers task. Since it's looping 6 times, it's creating 6 flower centers, each one giving off one spore.

EDIT: Demonbman: I can't figure out the problem in your script from what you posted on IRC, sorry. 

[Infy♫]

so how do i set the player's bombs, from a stage script?
i have only found a way to set lives, but nothing for bombs >:|

[Blargel]

Write your own function that uses common data. Then update it in the player script. First thing that comes to mind for me if there's really no way to do it in the normal Danmakufu functions.

[Infy♫]

When I use FadeOutMusic, the song wont start playing after I do PlayMusic again...
How do I solve this problem?!

[Demonbman]

EDIT: Demonbman: I can't figure out the problem in your script from what you posted on IRC, sorry. 

Could you please, explain what Naut ment by "absolute file paths" ?

Edit: Oh, Hi Naut...

[Iryan]

@ Demonbman

Are your plural file, the seperate attacks and the Data.txt all in the same folder? It just might be that danmakufu doesn't read the path description properly if the single and plural files are in different directories, especially when using .\ instead of GetCurrentScriptDirectory~.

Edit:

The reason I don't want you to use absolute path names (relative to th_dnh) is because people will extract files differently, and thus have different path names than what is on your computer. The script will error if you have used them, and it pisses me the fuck off when I have to dick through your scripts to find every absolute path name you've declared and change it to something that works on my computer. If you use relative path names, then it will always work no matter how anybody extracts your files.

Also this. So much this.

[Naut]

An absolute file path means that it is relative to your root directory (in this case, th_dnh).
script\bosses\holyshit.txt is an absolute file path, it is relative to th_dnh.exe.

A relative file path means that it gets the file path relative to the file you're calling it in. For example, if you have a text file in the folder script\bosses called dicks.txt, and you want to communicate to holyshit.txt for whatever reason, you can call it in an #include_function by saying:
.\holyshit.txt
The .\ gets the current directory of the file it's called in (just like GetCurrentScriptDirectory), and then follows the rest of the path name to the file you've specified. So in this case, it will find the directory that dicks.txt is in, and then find holyshit.txt in the same directory.

The reason I don't want you to use absolute path names (relative to th_dnh) is because people will extract files differently, and thus have different path names than what is on your computer. The script will error if you have used them, and it pisses me the fuck off when I have to dick through your scripts to find every absolute path name you've declared and change it to something that works on my computer. If you use relative path names, then it will always work no matter how anybody extracts your files.

so how do i set the player's bombs, from a stage script?

while(GetPlayerBombCount>1){
    AddBomb(-1);
}

When I use FadeOutMusic, the song wont start playing after I do PlayMusic again...
How do I solve this problem?!

Delete the music file after it has successfully faded out, then reload it.

[Demonbman]

An absolute file path means that it is relative to your root directory (in this case, th_dnh).
scriptossesholyshit.txt is an absolute file path, it is relative to th_dnh.exe.

A relative file path means that it gets the file path relative to the file you're calling it in. For example, if you have a text file in the folder scriptosses called dicks.txt, and you want to communicate to holyshit.txt for whatever reason, you can call it in an #include_function by saying:
.holyshit.txt
The . gets the current directory of the file it's called in (just like GetCurrentScriptDirectory), and then follows the rest of the path name to the file you've specified. So in this case, it will find the directory that dicks.txt is in, and then find holyshit.txt in the same directory.

So I pretty much have to include a copy of Data.txt in each Folder?
Because I has three seperate folders and they all have the same problem
scipt\Prisimrivers\
Lyrica\L01, LO2 etc..
Lunasa\L01, LO2 etc..
Merlin\M01, MO2 etc..

[Blargel]

Not necessarily. You can put the Data.txt file in the Prisimrivers folder outside of any of the specific sisters' folders. Then in any script you want to include the Data.txt into, you can put

#include_function ".\..\Data.txt"

The .\ as Naut already explained behaves like GetCurrentScriptDirectory. The ..\ on the other hand basically means "go back one folder". Now I haven't actually used this technique myself, but I've seen it used by other people before.

Also, do you realize that you're spelling their last name wrong? It's Prismriver last time I checked.  :V

[Demonbman]

hmm...this ... thing might become in handy...cool
Prisimriver...Prismriver...........oh curses 
EDIT: Oh, now it raises and error with cutin.txt.

[Helepolis]

The only time you are allowed to use absolute pathnames is when you release entire dnh folder in one go.

384x448

That's the size of the area the player can move in; I need the dimensions of the enitre game screen (which includes some bits the player can't move around in. Don't include the frame).

Probably my fault, I needed to be moar specific.
