※ Q&A/Problem Thread 6 ※ for OLD Danmakufu version (0.12m)

[I have no name]

So I'm trying to get curvy lasers to shoot bullets to generate a pattern. I know my code is kind of inefficient at the moment, but right now I just want it to work.

Code: [Select]

//example loop in case the problem lies there
while(i<12){
laser1(1,0,5,dir,4,0,5);
i++;
dir+=30;
}

//laser1
task laser1(id,frame,speed,angle,turn,accel,g){
CreateLaserC(id,GetX,GetY,12,50,108,0);
SetLaserDataC(id,frame,speed,angle,turn,accel,g);
SetLaserDataC(id,90,1.5*speed,angle,0,0,g);
CreateShotA(8,Obj_GetX(id),Obj_GetY(id),15);
SetShotDataA(8,0,1.5,Obj_GetAngle(id)+90,0,0,1.5,109);
CreateShotA(9,Obj_GetX(id),Obj_GetY(id),15);
SetShotDataA(9,0,1.5,Obj_GetAngle(id)-90,0,0,1.5,109);
AddShot(0,id,8,0);                 //inefficient but it's a test
AddShot(0,id,9,0);
AddShot(15,id,8,0);
AddShot(15,id,9,0);
AddShot(30,id,8,0);
AddShot(30,id,9,0);
AddShot(45,id,8,0);
AddShot(45,id,9,0);
AddShot(60,id,8,0);
AddShot(60,id,9,0);
AddShot(75,id,8,0);
AddShot(75,id,9,0);
AddShot(90,id,8,0);
AddShot(90,id,9,0);
AddShot(105,id,8,0);
AddShot(105,id,9,0);
FireShot(id);
}

Hi all, i have a problem...

First of all, let's say that i have a shootsheet (txt file and png file).

1- Where should i put them in the script (CSD) folder?

2- Ok, i have them in the folder. Now what should i write in script_enemy_main, initialize etc etc to make the shootsheet works?

3- Once the shootsheet works, here is my second question: i want to make nice looking lasers like Nue in UFO or in general lasers like the ones in the late games. What shootsheet should i download? What bullets in the shootsheet should i call? (as, for examples black amulets are number 95...nice lasers are number...? )

That said, thank you for your help. Post here a reply or even a PM if you want.

1. Technically you can place them anywhere you want but obviously it'd be better if you organize things. For the sake of simplicity, let's say your script is at script/stuff/MyScript.txt. If it's just a simple script, you can put the shotsheet image and script in script/stuff as well so you'll have script/stuff/shotsheet.png and script/stuff/shotsheet.txt.

2. In @Intialize, you need to put LoadUserShotData("path/to/the/shotsheet.txt");. You can do something like this and it should work.

Code: [Select]

let shotsheet = GetCurrentScriptDirectory ~ "shotsheet.txt";
LoadUserShotData(shotsheet);
I can't remember if LoadUserShotData actually loads the graphic automatically or not, but if it doesn't, you'll have to add LoadGraphic somewhere in @Initialize as well.

3. Sorry, I don't know about this one.

I can't run Danmakufu anymore so you'll have to describe what's wrong (or someone else can run the code and answer I guess lol). I don't use AddShot in the same way that you do, but to my understanding what you have should work. Can you describe what you're expecting to happen and what's really happening?

I'm expecting the lasers to fire bullets off in opposite directions perpendicular to the current direction of the laser.  What is happening is bullets are aiming straight up and down from the center of the pattern (the addshot at 0, setting this to 1 made a larger "ring" aimed up and down)

[LadyScarlet]

Okay, so my very first Danmakufu script is almost done. Here's how it looks so far:
http://i45.tinypic.com/npoydx.png

I mainly want to know how to get the indigo bullets (which I will change to purple for the final release) to spin around so there are no ⑨ blindspots (they're in abundance right now.) Like the large circle bullets in this video. or Yukari's Border of Wave and Particle. I'll make it go slower than those examples, of course, but the examples are to give you an idea what I'm talking about.

One thing I noticed was that in CreateShotA(8,Obj_GetX(id),Obj_GetY(id),15); you're using Obj_GetX(id) and Obj_GetY(id). That's not doing what you expect it to do, but it's still working because of a funny coincidence. You're supposed to put 0 for both x and y if you plan to use AddShot because it adds the x and y that you specify to the target bullet's x and y at the time. Obj_GetX and Obj_GetY is used for objects created with Obj_Create which you didn't use. If you pass in an unknown id into those functions, they happen to just return 0.

Likewise, Obj_GetAngle(id)+90 will actually return 0+90, so that's why it's shooting straight down. I'm not sure if there's a way to do what you want to do, but SetShotDirectionType may have some sort of application that you can use. Otherwise, you'll need to use object sinuate lasers, or perhaps someone else knows a way to do what you want.

[I have no name]

I see, I suppose I could do it with a series of carefully placed familiars and carefully timed bullets that shoot bullets, but I was hoping to do it with just the lasers.
Or object lasers.

edit
Why doesn't the following code make the boss move in an infinity sign (technical term leminscante I believe)

Code: [Select]

loop{
SetMovePositionHermite(GetX,GetY,0,330,2,90,180);
wait(180);
SetMovePositionHermite(GetX,GetY,0,90,2,210,180);
wait(180);
SetMovePositionHermite(GetX,GetY,0,210,2,90,180);
wait(180);
SetMovePositionHermite(GetX,GetY,0,90,2,330,180);
wait(180);
}

Sorry for my annoyance, but I'm now trying to get Helepolis' Custom Cutin script to work on my script. I keep getting an error with some faulty code, yet I do not know what's wrong:

Oh, here's the error:

If someone could please help me, that would be great. Thanks.

*Huge Block of Code*Oh, here's the error:

I think you guys may be forgetting the "large blocks of code in pastebin" rule.

Anyway, you're not doing the syntax for #include_function right. Remove the brackets and write it like this: #include_function ".\function_cutin.txt";

[I have no name]

I think you guys may be forgetting the "large blocks of code in pastebin" rule.

Didn't realize that was a rule, didn't think my block of code was that large.  I'll keep that in mind for the future though.

I have a quick question, is it possible to change the default font seen on the title screen and on the side bar during game?

[Lunasa Prismriver]

You can't change the font directly but you can change the font of the frame with objects effects.

[KiKi-KaiKai]

trying to do my first script. why the hell won't my graphics show up in danmakufu? I set the rect to the correct coordinates, and no matter how I even set it where images are, nothing will show. what is going on?! ;n;

Are you loading the graphics? That's often the problem.

[KiKi-KaiKai]

Are you loading the graphics? That's often the problem.

 
well, I've got this...

script_enemy_main {
    let imgBoss = "script\img\komachidot.png";
    let angle = 90;
    let frame = 0;
    @Initialize {
        SetX(GetCenterX);
        SetY(GetClipMinY + 120);
        SetLife(2000);

        LoadGraphic(imgBoss);
        SetTexture(imgBoss);
        SetGraphicRect(0, 0, 103, 161);
    }

    @MainLoop {
        SetCollisionA(GetX, GetY, 24);
        SetCollisionB(GetX, GetY, 24);

    @DrawLoop {
        DrawGraphic(GetX, GetY);
    }

    @Finalize {
        DeleteGraphic(imgBoss);
    }
}

anything wrong here?     

[Drake]

SetTexture and SetGraphicRect go in the DrawLoop.

[KiKi-KaiKai]

I did that, no image still shows...

these are the images, btw.

[Drake]

Oops your MainLoop has no closing bracket.

[KiKi-KaiKai]

oops, sorry about that. that's fixed, but how come the image isn't showing if everything is correct? ;n;

[Ozzy]

oops, sorry about that. that's fixed, but how come the image isn't showing if everything is correct? ;n;

Taking those corrections into account, I'm able to get the image to show up. Check that the file path to the image is correct.

[KiKi-KaiKai]

is it? because I tried with exrumia.png as a test in the folder earlier, and she showed up though..

[Shizzo]

 Hi everyone!

I'm having a bit of trouble running the fangame The Last Comer on my danmakufu. 

I downloaded and moved the bgm files to the game's folder, but whenever I tried to play it the game crashes when the stage 1 boss appears for the boss battle.  Has anybody here downloaded the game and got it running properly, or knows how to fix the event script so it works?  Thanks in advance. 

[LadyScarlet]

I'm having trouble trying to get my script to work (AGAIN. Whenever I try to edit one single thing, it crashes and I have to change it back >.<) This time, I've got an error at the DrawLoop section. However, I can't figure out what it is, so I've posted it and a few lines above to hopefully ring a bell (that reminds me; I really need to get over my loss and start playing ToV PS3 again) :

Code: [Select]

count = 0;

count++;
            }

    @DrawLoop {
SetTexture(yukari);
SetRenderState(ALPHA);
SetAlpha(255);
SetGraphicRect(0,0,80,96);
SetGraphicScale(1,1);
SetGraphicAngle(0,0,0);
        DrawGraphic(GetX, GetY);

    }
What is the error? Thanks.

[I have no name]

The loop itself looks fine, the first thing I can think of would be a bracket error somewhere in the code (probably up with the count stuff) but that's impossible to tell without seeing the rest.

[LadyScarlet]

Well, I have a pastebin link to the entire code right here:
http://pastebin.com/A6ybRELj
If you want me to post the entire script folder on Mediafire, I can do that, too. Just ask.

[I have no name]

Yep, if you look carefully at MainLoop, you need another bracket at the end.

Code: [Select]

count++;
            }
}   <---this wasn't there before

    @DrawLoop {


That should work.
One other thing I noticed is there's no yield statements, so if Danmakufu crashes when you try to run the script (no errors) that's why.  Not sure if MainLoop scripting needs those though.

[LadyScarlet]

So that's fixed, but now I can't get anything other than the purple bullets to fire. Did I put in the wrong things?

[I have no name]

I decided to take a closer look at your script and found a few other things.  I have no idea if my changes are correct or not, as I've been using a shotsheet (and task scripting instead of MainLoop scripting)

I've helpfully added comments to what I changed explaining why I changed it.  If you're not clear on anything, ask, and I or someone else will answer by tomorrow afternoon.  For now though, sleep.

[LadyScarlet]

Maintask is invalid for some reason. When trying to boot up the script, I get this error:

Thanks for the revision, by the way.

[I have no name]

The only difference from what I have working (aside from parameters and such) is I don't have shotinit-what exactly does that do/what happens if you comment it out?

[Fujiwara no Mokou]

maintask and @Finalize  are prematurely omitted because of the two '}'.
You may want to get rid of it.
