Danmakufu Q&A/Problem Thread

[Suikama]

Is it possible to draw a black object?

Danmakufu keeps cuting out all the black when I try to draw a black object...

Edit: Alright found out how to do it. Just gotta change it very slightly from pure black.

Yeah.

Just to clarify, if you have an image with pure black (RGB 0,0,0), Danmakufu treats that as transparency (probably a simple way to cover for the fact that several image formats lack a transparency channel).

Oh, question: How are people able to do things like show how many point items you need for the next Extend on the border? I've never seen a function that allows this at all, and I'd like to know how it's done.

You use the SetNormPoint function. Yes, its name is woefully undescriptive.

Hi i have another question, is there a way to have the boss wait to fire untill specified, but not delayed?,  like start the attack after so much time?

[RavenEngie]

How do you mean, like the pause at the start of a spellcard, a pause between waves of bullets, or what?

at the start

[RavenEngie]

Just put the variable that you use to make things happen at a lower value (or higher, if you make it go down once a frame).

Like this.

Code: [Select]

script_enemy_main{

        let frame = -120;

        everything else you need;

        @MainLoop{

              if(frame > 0 && whateverelse){
                      stuff happens;
              }
         frame ++;
}
Now there'll be a two-second pause between 'stuff happens' and the start of whatever.
That's what you meant, right?

Nah, I have a better idea. How about make a dummy script that does nothing except draw the boss adn if needed, move the boss?

It gets even better.

Based on my recent experience (NTSD), All SetNormPoint does is display the threshold value.  Apparently you need to put code in yourself to actually give the player an extra life.

... unless I royally screwed something up somewhere :V

Time stopping... in Danmaku Bounded Field? :V
I think you're mistaking this with other spellcard.

No, I'm pretty sure it's Y's A: DBF. Like when the player character gets killed, the magic thing around Yukari stops spinning and the timer stops counting down, until the player loses all of her invincibility.

Oh, you mean THAT kind of timestop. I'm pretty sure that to do that effect, you can call a modification on the familiar's movement when the player dies. And since it's a familiar, you can use the familiar script to make it stop shooting as well while the player's invincible.

No, i want the timer to stop counting down...

Aaaand, done.

Code: [Select]

if(GetTimeOfPlayerInvincibility != 0 || OnBomb) {
SetDamageRate(0, 0);
SetTimer(GetTimer+1);
}
Why didn't I think of that months ago?

[Helepolis]

I have been extremely busy again revising my afro boss. Tweaked alot of things but ONE thing is still bothering me which I failed to change.

How do a create a fountain effect for bullets:
- Bullets spawn up with random direction
- Each bullet has a random de-acceleration time ( some fast , some slow )
- Bullets fall down at a random speed in the same arched path they made during the de-acceleration

A picture show what I want to achieve:
(basicly a parabole for each bullet)

Right now I have this:

Code: [Select]

CreateShotA(1,70,460,20);
SetShotDataA(1,0,6,rand(265,275),0,0,0,221);
SetShotDataA(1,30,5,rand(260,280),0,0,0,221);
SetShotDataA(1,80,3,NULL,0,0,0,221);
SetShotDataA(1,100,rand(0.2,2.5),rand(60,120),0,0,0,221);
FireShot(1);

CreateShotA(2,70,460,20);
SetShotDataA(2,0,6,rand(265,275),0,0,0,46);
SetShotDataA(2,30,5,rand(260,280),0,0,0,46);
SetShotDataA(2,80,3,NULL,0,0,0,46);
SetShotDataA(2,100,rand(0.2,2.5),rand(60,120),0,0,0,46);
FireShot(2);
But this looks extremely ugly as the bullets sudden change direction (using the angle). I want to make this a fluent fountain effect just like in the original Uwabami game. A reference to my replay with the spellcard in action:
http://www.youtube.com/watch?v=ZNMcYDtHiBI&fmt=18#t=1m38s

[CK Crash]

I'm thinking it would be best to use the XY versions of CreateShot and SetShotData for this. Also, don't forget you can use both the normal SetShotData and the XY version on the same bullet (although it's hard to keep the direction and speed constant).

[Iryan]

CreateShotA(1, x, y, 0);
SetShotDataA_XY(1, 0, v*cos(angle), v*sin(angle), acc, 0, 5, 0, graphic);
FireShot(1);

x,y = starting position
v = starting speed
angle = firing angle of the bullet; should be between -90? and +90?
acc = downward acceleration, or gravity; should be between 0.01 and 0.1


That should do fine.

[Helepolis]

It is coming close, except the bullets fly away like this :V

SetShotDataA_XY(1,0,3*cos(rand(265,275)),3*sin(rand(265,275)),0.05,0,5,0,221);

[Iryan]

ARGH!

Stupid me, always confusing the x and y axis! (Axiss? Axises? Axii? Axen? Who cares?)

It has to be:

SetShotDataA_XY(1,0,3*cos(rand(265,275)),3*sin(rand(265,275)),0,0.05,0,5,221);

If the bullets accelerate towards the right side of the filed instead of the bottom, well...  :V

[puremrz]

I'm in despair once again!

I'm trying to make a circle of reflecting bullets, but the best I got is a script for a very unefficient horizontal reflection.

This is what I made of the object shots:

Code: [Select]

if(frame==100){
loop(10){
circle[a]=Obj_Create(OBJ_SHOT);
Obj_SetPosition(circle[a],GetX,GetY);
Obj_SetSpeed(circle[a],2);
Obj_SetAngle(circle[a],-30+angle);
ObjShot_SetBombResist(circle[a],true);
ObjShot_SetGraphic(circle[a],RED01);

angle+=36;
a+=1;
}
}

if(frame>100){
a=0;
loop(10){
if(Obj_GetX(circle[a])<GetClipMinX) {
Obj_SetAngle(circle[a],180-Obj_GetAngle(circle[a]) );
Obj_SetX(circle[a],Obj_GetX(circle[a])+0.1);
}
if(Obj_GetX(circle[a])>GetClipMaxX) {
Obj_SetAngle(circle[a], 180-Obj_GetAngle(circle[a]) );
Obj_SetX(circle[a],Obj_GetX(circle[a])-0.1);
}
if(Obj_GetY(circle[a])<GetClipMinY) {
Obj_SetAngle(circle[a],180-Obj_GetAngle(circle[a]) );
Obj_SetY(circle[a],Obj_GetY(circle[a])+0.1);
}
if(Obj_GetY(circle[a])>GetClipMaxY) {
Obj_SetAngle(circle[a], 180-Obj_GetAngle(circle[a]) );
Obj_SetY(circle[a],Obj_GetY(circle[a])-0.1);
}
a+=1;
}
}

I also would like to know how you can let arrays fill themselves for easy mass modifying. Because "let circle=[0,1,2,3,4,5,6,7,8,9,10...etc" doesn't look very neat, and if you want to have more than 300 bullets on the screen at once, doing it this way will take forever.

[Helepolis]

Thank you Iryan :x it works like a charm now. I just had to fool more with the speed and acceleration to make it more perfect.

It had a huge impact on the diffuclty of the spellcard, I had to test alot.   :V

~ combines stuff. Use it to add items into arrays.

eg.
let array1 = [a]
array2 = array1 ~ "b"

Now array2 is ["a", "b"]


If you want to mass add stuff, use ascent.

eg.
let array1 = []
ascent(i in 0.. 10){
    array1= array1 ~ i
    }

Now array1 is [0, 1, 2, 3, 4, 5, 6, 7, 8, 9].

im trying to recreate the backround on Satori' Spell cards but i cant seem to get the other pictur to draw..or spin for tat matter... ive tried BGSpin and set at up, but nothing happens..

Have you read Nuclear cheese's drawing tutorial? It explains like clearly how to layer backgrounds in the @BackGround Loop. The first BG in the loop will be at the bottom. The next one will overlap the first. etc.

For tilting/spinning things you need to use: SetGraphicAngle(0,0,<variabel>); where the variabel gets increased by the value you want at the end of.

yes ive read the drawing tutorial, but m not sure what the code is fr it

[Helepolis]

Try this for each BG you add to the BackGround

   SetTexture();
   SetRenderState();
   SetAlpha();
   SetGraphicRect();
   SetGraphicScale();
   SetGraphicAngle();
   DrawGraphic(GetCenterX, GetCenterY);

Always end with DrawGraphic then start the 2nd BG you want as top layer repeating the above.

[Demonbman]

Just put the variable that you use to make things happen at a lower value (or higher, if you make it go down once a frame).

Like this.

Code: [Select]

script_enemy_main{

        let frame = -120;

        everything else you need;

        @MainLoop{

              if(frame > 0 && whateverelse){
                      stuff happens;
              }
         frame ++;
}
Now there'll be a two-second pause between 'stuff happens' and the start of whatever.
That's what you meant, right?

}

@MainLoop{
frame++;
if(frame == -180) { Concentration01(120); }
if(frame == 0) { AddLife(-100001); }
}

@DrawLoop{
//Draw the boss here
}

@Finalize
{
//Delete graphics and other finalization stuff
}

}

I tried that and it just straght forward went into the next atack

Replays desync on this, it is not fun

When I saved my replay it shows 2 replays with the same name, date, time but one is called #01 and one is called User. The 01 one is out of sync somehow but the User replay is not.

Though the question is, how do I get two replays suddenly?
