Danmakufu Q&A/Problem thread number 4

[Azure Lazuline]

Code: [Select]

LoadUserShotData(CSD ~ "\shots\supershot.png");

I'm not sure if this is the only problem, but you should remove the "\" before "shots." GetCurrentScriptDirectory includes the last slash, so that would double it up and make the directory incorrect.

I've modified that, but it's still not working.

Still, many thanks.

[Demonbman]

Your loading an image, not a shotdata


Shotdata must be a .txt, you can't load a image and call it shotdata

Indeed, that's what was going wrong. Many, many thanks.

Code: [Select]

CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer-5,AQUA01,20);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+5,AQUA01,20);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer-15,AQUA01,20);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+15,AQUA01,20);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer-25,AQUA01,20);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+25,AQUA01,20);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer-35,AQUA01,10);
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+35,AQUA01,10);


wait(30);
yield;


Err, I know your question has been answered, but just some things I'd like to mention...
I quoted a segment of a task in your script.
First of all, there is no need for writing out the CreateShot01s again and again, not only is it bothersome, it also makes it more difficult to make changes. You could use a loop to do something similar easily. For example:

Code: [Select]

let i = -35;
while(i <= 35)
{
CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+i,AQUA01,10);
                        i += 5;
}
Can replace the bunch of CreateShot01s in the quote.

Secondly, you called the function wait(30), which basically is identical to writing " yield; yield; yield;... " 30 times, therefore the yield; at the end of your task is actually unnecessary. I just thought I'd mention this as the additional yield might throw off the timing of your danmaku pattern a bit. (Which I think it will because instead of every loop having yield;s in multiples of 10, you have them as numbers like 11, 61, etc. )

Finally, the yield; in the task mainTask is not necessary because you're not trying to loop anything and you need not stop the task for a frame.

Hope this helps with your scripting.

I personally prefer using ascents. Arbitrary variables etc. You can use a local wrapper to do the same thing, but massive sigh anyways. Also, as a general guideline, similar bullets in any one pattern should all have the same amount of delay, and instead be launched later.

Code: [Select]

ascent(i in -3..4){
    CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+(i*10),AQUA01,10);
}
wait(10);
ascent(i in -7..8){
    if( (| (i*5)%10 |) == 5 ){
        CreateShot01(GetEnemyX,GetEnemyY,4,GetAngleToPlayer+(i*5),AQUA01,10);
    }
}

Sum more questions  :]

I don't know why but why does the background and the drawloop connects to each other ?

http://s477.photobucket.com/albums/rr139/namethecool/Games/?action=view&current=b5.png

Code: [Select]

    @DrawLoop {
DrawAnimatedSprite("reimu", GetX, GetY);
DrawText("Minoriko Aki", 50, 50, 12, 255);

    }

   @BackGround
   {

LoadGraphic(BossImage2);
SetGraphicScale(5, 5);
SetTexture(BossImage2);
SetGraphicRect( 0, 0, 256, 256 );
SetGraphicAngle(0, 0, rotation);
DrawGraphic(GetCenterX , GetCenterY );


   }

    @Finalize {
      DeleteGraphic(BossImage2);
    }

And why can't you have backgrounds for non- spell cards ?

- LoadGraphic has to go to @initialize, not in @background
- I don't know what exactly DrawAnimatedSprite does, seems like a function or library. Cannot fully judge what your problem is.

And why can't you have backgrounds for non- spell cards ?

Because it is Danmakufu. If you want background for non-spells, you need to work with stage scripts.

[Drake]

He's using Blargel's Animation Library.

In any case, don't load the background graphic in the BG loop. Load it in Initialize.

Have you even tried resetting the values to normal during DrawLoop? SetGraphicScale(1, 1);? SetGraphicAngle(0, 0, 0);?

I'm trying to make a caterpillar-like effect for a chain of object bullets/effects.
In other words, one bullet/effect will lead, and the others will follow its exact path with a set time and/or distance between them.

How would I properly code that in danmakufu? It has left me clueless!

[Demonbman]

I have an idea, but it would depend on how many bullets you wanted to do the  caterpiller affect  too

[puremrz]

I have an idea, but it would depend on how many bullets you wanted to do the  caterpiller affect  too

I got various uses for it, so it's pretty variable. But the most important one is about 10-15.

[Demonbman]

It pretty much works like this, the ID of the object would have to be a number, and it would pretty much go like this:


if(count%howmanybulletsyouwant==(Id of the Object){
SetPosition(Id of the Object,LastX,LastY,2);
LastX = Obj_GetX(Id of the Object);
LastY= Obj_GetY(Id of the Object);
}


While having count increasing MainLoop, put this in the object bullet's code. It would cause that when the condition is met, to but the bullet at the last know X and Y, which would be the previous bullet's, so now this bullet is taking the other bullet's place


Does this work for you?

[puremrz]

I'll try it out when I get home. ^_^
I'm not too familiar with how % works, but it seems it'll be useful in more ways than 1 if you can also use it for this.

I tried moving LoadGraphic(BossImage2); to @Initialize and did what you said, it's still connected  :/

Have you tried setting back the Angle and Scale like Drake also said?

[Foremoster]

yes  :V still connected

[Demonbman]

Try putting the SetScale after you call the Texture

[Thaws]

Wouldn't something like

Code: [Select]

SetGraphicScale(5, 5);
SetTexture(BossImage2);
SetGraphicRect( 0, 0, 256, 256 );
SetGraphicAngle(0, 0, rotation);
DrawGraphic(GetCenterX , GetCenterY );
SetGraphicScale(1, 1);
work?
That way, it doesn't matter if the loops are connected or not.

Edit : Oops Drake already said it long time ago. What are you trying to achieve by making them not connect though?

Eh.....
Why not just use a sinuate laser, or maybe you're trying to make something out of this effect??

Or you can just add delay to the trailing bullets. I think.

[Kylesky]

Eh.....
Why not just use a sinuate laser...?

Uhhh... maybe to split the bullets from the line at some point? or maybe because caterpillars are circles instead of a smooth line...

[Foremoster]

Edit : Nvm thankyou all for your time helping me

SetTexture(BossImage2);
SetGraphicRect( 0, 0, 256, 256 );

SetGraphicScale(1, 1);

Almost >_< the background is working now but, minoriko is still spinning even though she doesn't have rotation. Do not want them to connect because it looks weird if the boss is huge and spinning.

This is why I can't script nice things  :colonveeplusalpha:

SetGraphicScale(1, 1);
SetGraphicAngle(0, 0, 0);


Basically you reset the scale and angle values to normal after you draw your background, so whatever you draw in your DrawLoop comes out normally.

[Drake]

If you're really having that much trouble with it, take your entire script and talk to Blargel about it.

[Zerro]

I need help on making events different depending on which character you use.

I have found the GetPlayerType function but I don't know how I would use it for
a custom player and not Reimu or Marisa.

Or how to use it period, really.

[Foremoster]

I have found the GetPlayerType function but I don't know how I would use it for
a custom player and not Reimu or Marisa.

I'm a beginner myself, but I think it's something to do with

Code: [Select]

if ((GetPlayerType == REIMU_A) || (GetPlayerType == REIMU_B))
and you can do SetStep(1); if the character is Reimu A and SetStep(2); if it's Reimu B. I think if you want to change the character you link the file your character is in. like GetCurrentScriptDirectory ~ "something".

Code: [Select]

else if ((GetPlayerType == MARISA_A) || (GetPlayerType == MARISA_B))and if it's not reimu and it's either marisa A or marisa B then stuff happens

or just any character you can just do

Code: [Select]

else

So I got Dnamakufu 0.12m, installed East Asian language files, tried to run it with Applocale... and still it crashes on opening.

Without applocale, it opens fine but crashes when I pick an option in the menu. I'm running XP.

Halp?

[Naut]

So I got Dnamakufu 0.12m, installed East Asian language files, tried to run it with Applocale... and still it crashes on opening.

Probably running it under the wrong language? Japanese should be the very bottom option. If it doesn't work, you can switch your whole computer's locale to Japanese in the Control Panel, restart, then run Danmakufu normally. It should work fine. Switching your computer to Japanese locale will change almost nothing, so don't worry about it screwing with other programs.

No, I definitely ran it in japanese. I changed the computer's locale to Japanese and ran it, but it's the same as before - crashes when I go into any option on the main menu.

EDIT: Problem solved - I had to remove the EX Rumia and player Rumia files. Thanks puremrz!

[Stuffman]

EDIT: Problem solved - I had to remove the EX Rumia and player Rumia files. Thanks puremrz!

Then Applocale isn't working right, because the reason Rumia crashes it and the reason Applocale fixes it is Danmakufu doesn't like scripts with moonrunes in them when running english settings.




Formula? :ohdear:

EDIT:
I think the first thing that needs to be done is to locate the point on the wall where it's going to rebound. I had the idea of getting the Y distance between the enemy and player to get the amount of wall that needs to be traversed, and then getting the X distance from the wall for both and comparing them to get a ratio of how much wall would be between them on the bounce.

Code: [Select]

ydist=GetPlayerY-GetY;
// get y distance between enemy and player
yratio=(GetX-GetClipMinX)/((GetX-GetClipMinX)+(GetPlayerX-GetClipMinX));
// get ratio of distance from wall for enemy and player (assuming left wall here)
ypoint=GetY+(ydist*yratio);
// apply ratio to y distance to get how far down the wall it needs to bounce
angle=atan2(GetClipMinX-GetX,ypoint-GetY);
// get the angle to that point
pointdist=((GetX-GetClipMinX)^2)+((GetY-ypoint)^2);
pointdist=pointdist^0.5;
// gets distance from enemy to that point
pointdist=floor(pointdist/2);
// divides by two for number of frames travelled, to know when to reflect (speed 2)
CreateShotA(0,GetX,GetY,0);
SetShotDataA(0,0,2,angle,0,0,0,65);
SetShotDataA(0,pointdist,2,180-angle,0,0,0,65);
FireShot(0);


Why not worky?

EDIT 2:
angle=atan2(GetClipMinX-GetX,ypoint-GetY);
angle=atan2(ypoint-GetY,GetClipMinX-GetX);
Not worky because y coords need to go first in atan2. Goddamnit :fail:

So there's how to do it if anyone wants to know, I guess
