Danmakufu Q&A/Problem Thread v3

[Furienify]

AHASHAHAHA I found an error

You forget the closing ] bracket in one of the #Text[] lines.

Therefore the entire script was considered to be the text for the script. However, since danmakufu reads the playing part of the script from script_enemy_main onwards, the script was still playable. Then, when archiving, things gout fucked up.

Moep, now I may just as well listen Octavarium through till the end.  :V

It WORKS! Thanks so much. :*

[Kylesky]

tried the 2D arrays idea... now CURRENTHS always gives me 0... It's not changing/updating the value... don't know if I'm doing this right or not...

Code: [Select]

SetCommonData("HISCOREARRAY", [[0,0,0,0],[0,0],[0,0,0,0 blah blah etc... ]);
let array= [blah, blah2, blah3];
SetCommonData(GetCommonData("HISCOREARRAY")[0], array);
SetCommonData("HISCOREARRAY"[0], array);
^these lines aren't actually part of the code... they're just there to show the basis of the code...

I've never used arrays for common datas...

Code: [Select]

if(GetCommonData("SCORE")>GetCommonData("HISCOREARRAY")[0][0])
{
SetCommonData("HISCOREARRAY"[0], array); //or SetCommonData(GetCommonData("HISCOREARRAY")[0], array);
}
SetCommonData("CURRENTHS", GetCommonData("HISCOREARRAY")[0][0]);

None of them are working... :ohdear:

[Azure Lazuline]

GetCommonData("HISCOREARRAY")[0][0]

You put the array index in the wrong place.

[Kylesky]

GetCommonData("HISCOREARRAY")[0][0]

You put the array index in the wrong place.

I don't really get what you said... cause that's exactly what was in my code... (I'm an idiot :/)

I did some testing... moved pieces of code around and stuff... and as I thought

Code: [Select]

SetCommonData(GetCommonData("HISCOREARRAY")[0], hsarrayb);
this line has always been the problem... I really don't know how to change arrays INSIDE commondatas...

Code: [Select]

hsarrayc=GetCommonData("HISCOREARRAY");
hsarrayb=[GetCommonData("SCORE"), GetCommonData("HISCOREARRAY")[0][1],
GetCommonData("HISCOREARRAY")[0][2], GetCommonData("HISCOREARRAY")[0][3] ];
hsarrayc[0]=hsarrayb;
if(GetCommonData("SCORE")>GetCommonData("HISCOREARRAY")[0][0])
{
SetCommonData("HISCOREARRAY", hsarrayc);
}
SetCommonData("CURRENTHS", GetCommonData("HISCOREARRAY")[0][0]);
What a workaround... :V at least I got it working...

[Azure Lazuline]

Oh, I misread your SetCommonData("HISCOREARRAY"

• ,something) line as GetCommonData, my bad. (Hey, it's only one letter different and it was really late at night...) Yeah, in order to change only one value, you have to use that workaround you found out. At least it works, right?

[Nobu]

Quick dumb question here. I'm trying to append object ids to an empty array, but I get the error that i'm not concatenating the write data type. Do I have to turn the object ID into a string or something, or do something special with the array?

Relevant code:

let thearray = [];

let obj = Obj_Create(OBJ_SHOT);
thearray =  thearray ~ obj;

[8lue Wizard]

thearray =  thearray ~ [obj];

should work.

[Nobu]

Ohh, I get it. Thanks a lot. o/

[Drake]

Just to clarify (even if you said you get it), you were trying to concatenate an object to an array. Technically it's just invalid because you can only concatenate two arrays. So just throw the object into a make-believe array and poof.

[Danielu Yoshikoto]

I need help with a simple Menu script.
I used "Wonderful☆Life's Introduction to Menus" as a base, but my Danmakufu keeps crashing after it told me that something is wrong with "enemy_script_main".

Code: [Select]

#?????e????
#Title[Some Title]
#Text[Some Text]
#Player[FREE]
#ScriptVersion[2]

script_stage_main{

let Selection=0;
let warning=0;
let alph1=150;
let alph2=150;
let alph3=150;
let alph4=0;
let alph5=0;
let MenuBG=GetCurrentScriptDirectory~"IMG\MenuBackground.png"
let Icon1=GetCurrentScriptDirectory~"IMG\Cirno.png"
let Icon2=GetCurrentScriptDirectory~"IMG\Daiyousei.png"
@Initialize{
LoadGraphic(MenuBG);
   SetLife(1);
}

@MainLoop{
if(GetKeyState(VK_UP) == KEY_PUSH){Selection+=1;warning=0;}
if(GetKeyState(VK_DOWN) == KEY_PUSH){Selection-=1;warning=0;}
if(GetKeyState(VK_SHOT) == KEY_PUSH && Selection==0){warning=1;}
if(GetKeyState(VK_SHOT) == KEY_PUSH && Selection==1){warning=1;}
if(GetKeyState(VK_SHOT) == KEY_PUSH && Selection==2){ClearStage;}
}

@DrawLoop{
DrawText("Idiot",GetCenterX,GetCenterY,15,alph1);
DrawText("Triple Idiot",GetCenterX,GetCenterY-20,15,alph2);
DrawText("EXIT",GetCenterX,GetCenterY-60,15,alph3);
if(Selection==0){alph1=255; alph2=150; alph3=150;}
if(Selection==1){alph1=150; alph2=255; alph3=150;}
if(Selection==2){alph1=150; alph2=150; alph3=255;}
if(Selection==0&&warning==1;){alph4=255;}else{alph4=0;}
if(Selection==1&&warning==1;){alph5=255;}else{alph5=0;}
if(Select>2){Select=2;}
if(Select<0){Select=0;}

SetTexture(Icon1);
SetGraphicRect(0,0,128,128);
SetAlpha(aplh4);
DrawGraphic(GetCenterX-64,GetCenterY);

SetTexture(Icon2);
SetGraphicRect(0,0,128,128);
SetAlpha(aplh5);
DrawGraphic(GetCenterX-64,GetCenterY-20);
}

}
I bet it is like the most simplest thing, but I was too stupid to find it.
Also yes this was only a test to see if the options on the menu would work, If so they should display a small picture on the side of the option, when chosen, and when the option was changed it would disappear again.

[Naut]

You script needs to start with #TouhouDanmakufu[Stage] if you're using script_stage_main. Also, enemy_script_main doesnt exist, it's script_enemy_main.

Please tab your code.

[Drake]

#TouhouDanmakufu[Stage]fuckgoddammit naut

[Danielu Yoshikoto]

So yeah... after fixing that... (and also some other errors) I am now with the problem that nothing appears...

I think something is wrong with the overall script.

Code: [Select]

let MenuBG=GetCurrentScriptDirectory~"IMG\MenuBackground.png";
let Baka=GetCurrentScriptDirectory~"IMG\Cirno.png";
let Baka2=GetCurrentScriptDirectory~"IMG\Daiyousei.png";
@Initialize{
LoadGraphic(MenuBG);
LoadGraphic(Baka);
LoadGraphic(Baka2);
}
[...]
@DrawLoop{

SetTexture(MenuBG);
SetGraphicRect(0,0,400,480);
SetAlpha(255);
DrawGraphic(GetCenterX,GetCenterY);

DrawText("Idiot",GetCenterX,GetCenterY,15,alph1);
DrawText("Triple Idiot",GetCenterX,GetCenterY-20,15,alph2);
DrawText("EXIT",GetCenterX,GetCenterY-60,15,alph3);
if(Selection==0){alph1=255; alph2=150; alph3=150; alph4=0; alph5=0;}
if(Selection==1){alph1=150; alph2=255; alph3=150; alph4=0; alph5=0;}
if(Selection==2){alph1=150; alph2=150; alph3=255; alph4=0; alph5=0;}
if(Selection==0&&warning==1){alph4=255}
if(Selection==1&&warning==1){alph5=255}
if(Selection>2){Selection=2}
if(Selection<0){Selection=0}

SetTexture(Baka);
SetGraphicRect(0,0,128,128);
SetAlpha(alph4);
DrawGraphic(GetCenterX-64,GetCenterY);

SetTexture(Baka2);
SetGraphicRect(0,0,128,128);
SetAlpha(alph5);
DrawGraphic(GetCenterX-64,GetCenterY-20);
}

}I am seriously too dumb for menu scripting, I think.

[Drake]

Nothing appearing as in...?

[Danielu Yoshikoto]

Nothing appearing as in...?

Only Standart Danmakufu Stage Background and Player.

[Naut]

@DrawLoop does not work for stage scripts. You need to throw all your drawing functions in @BackGround. The reason why nothing errors is because Danmakufu just completely ignores the @DrawLoop in stage scripts.

Thanks for the help.
I will be sure to not credit you for the help with the menu.

How about @MainLoop?
Do effect objects work in @MainLoop?

[Naut]

Yes they do. When you yield out of a @MainLoop to tasks, Danmakufu still treats it as if you're still in the @MainLoop, which is why you can't draw things using DrawGraphic or anything like that in tasks. If you yield out of your @DrawLoop, you can (in enemy scripts and whatever). Same with yielding out of the @BackGround.

[Suikama]

So uh then, what exactly does MainLoop have over DrawLoop anyways?

[Naut]

Spawns bullets.

[Suikama]

I think you can still shoot bullets with the DrawLoop though...

[Naut]

So you can. Well, @MainLoop is force ran at 60 fps. So there.

Don't make me try to justify Danmakufu's way of doing things.

[Kylesky]

Is there a way to check if the player was hit/used a bomb while LastSpell is activated and you didn't use SetScore (so there's no using GetSpellCardBonus)? OnPlayerMissed isn't working... and checking if the number of lives/bombs decreased doesn't work either... Should I make my own task for declaring LastSpell like

Code: [Select]

let playerlife=GetPlayerLife;

function HitCheck //to be called every frame in @MainLoop
{
ForbidBomb(true);
if(OnPlayerMissed==true)
{
AddLife(-GetLife);
}
}

function BonusCheck //to be called in @Finalize
{
ForbidBomb(false);
if(GetPlayerLife<playerlife)
{
ExtendPlayer(1);
return false;
}else{
return true;
}
}


Code: [Select]

@MainLoop
HitCheck;
...etc...
@Finalize
if(BonusCheck==true)
{
AddScore(blah);
}
...
wait... why did I even post this if I already thought of a workaround... guess it's me being too lazy to edit 200 notepad files :V

[Danielu Yoshikoto]

Is there a way to check if the player was hit/used a bomb while LastSpell is activated[...]

Wasn?t there this simple "LastSpell" function you can call in initialize?

[Kylesky]

Wasn?t there this simple "LastSpell" function you can call in initialize?

I was using that... but apparently I can't check if the player was hit unless you use SetScore(value) then put if(GetSpellCardBonus==true) in @Finalize... but my question was... how do you check if you didn't use SetScore...

[Drake]

Why would you need to check for LastSpell if the pattern isn't even a card in the first place?

[Elementoid]

I've got another little situation that I need help with. Basically I need to find the distance between an object and the player so that the object can behave differently when in close proximity to it.

My first attempt was ugly and would have only acted in a square around the player. There was something wrong with it, though,  and it seemed like too much of a hassle to try and fix. Next, I tried looking for a function that could just find the distance for me, to no avail. Then I realized that I could just make my own using the distance formula (hooray for geometry) but I don't know how to tell danmakufu to find the square root of a number. (I'm assuming that ^ will work for exponents.)

If someone knows how to do that, or a function that I overlooked, some insight would be much appreciated.

[Kylesky]

I made my own Score function... so yeah... it's a card... just... danmakufu doesn't think it is :V

^0.5 raised to the 0.5 is the same as getting the square root...

It's so nice to have MotK back :V

[Elementoid]

  I didn't know that. Wow...

Thanks a bunch. That will definitely be a useful tidbit to know from now on...
