I've ended up with the same issue as LavaLake regarding stage enemies not being deleted upon exiting the screen.

My proof came when I had a WaitForZeroEnemy that never came and sound effects constantly repeating. Also, for testing the boundaries, do you use config.exe?

Here is my enemy script. (only important parts)
FYI: I never tested this particular one b/c it never appeared. However, I copied and pasted an earlier enemy script that shared the problem and just added the movement and different bullets.

Code: [Select]

script_enemy_main{
  //vars
  @Initialize{
    LoadGraphic(yrm);
    LoadUserShotData(ZUNbullet);
    SetLife(500);
    LoadSE(bullet);
  }
  @MainLoop{
    SetCollisionA(GetX, GetY, 32);
    SetCollisionB(GetX, GetY, 24);
    SetMovePosition01(GetArgument, GetCenterY - 20, 4)
    if(count > 150 && count % 30 == 0){
      //bullet data
      PlaySE(bullet);
    }
    count++;
    yield;
  }
  @DrawLoop{
    SetTexture(yrm);
    DrawGraphic(GetX,GetY);
  }
  @Finalize{
  //item
  }
}

For some reason I was thinking they would delete like shots if they went enough off screen. Hrm. In any case,

Code: [Select]

function CheckBoundaries(l, r, t, b){
if(GetX < l || GetX > r || GetY < t || GetY > b){
VanishEnemy;
}
}

VanishEnemy;

That's an extremely roundabout method. However, when I look at other stage scripts, they seen to not have the error. Well, thank you anyway. I'll see if it works.
P.S. Would you insert GetClipM(in/ax)(X/Y) into the function?

Edit: Shockman's stage does not even delete the enemies in the enemy script. The Last Comer uses the function that you just posted above (a variation) and something that I cannot find the meaning of (it's a boolean called enmfin). THe SA Phantasm uses vanish time.

[Drake]

You wouldn't use GetClips. Clip distance is pretty short and in most cases you want the enemies to start behind the clip distance.

The best method is probably having the enemy delete after a certain amount of time since it uses almost no extra processing. But you can't really generalize something like that; you have to cater it specifically to the stage and enemy, so it's slightly more difficult to implement. At least if you set boundaries you can just give it to every enemy and call it a day.
Also, Shockman does use a deletion timer, you weren't looking hard enough :P

When I try to create an object bullet, it freezes.:wat: Wat do I do to fix it?

[Drake]

put your script on pastebin and post the pastebin link here so we can see what you're talking about

[Sparen]

Well, the stage enemy fix is done. I decided that I'd alternate between the two methods depending on what was needed, and the stage script now runs almost-perfectly.

[Sparen]

New question about stage scripts:

Code: [Select]

  task Stage{
    wait(1); //Required to be here, greater than 0.
    PlayMusic(music1);
    CreateEnemyBossFromFile(section1, GetCenterX, 0, 1.4, 90, 0);
    WaitForZeroEnemy; //MANDATORY or the rest of the code will never be executed!!!
    wait(60);
    CreateEnemyBossFromFile(section2, GetCenterX, 0, 1.4, 90, 0);
    WaitForZeroEnemy;
    FadeOutMusic(music1, 30); //3 seconds to fade out
    wait(120);
    Stage1;
    wait(120);
    PlayMusic(music1);
    CreateEnemyBossFromFile(section4, GetCenterX, 0, 1.4, 90, 0);
    WaitForZeroEnemy;
    wait(180);
    Clear;
  }
Basically, the second PLayMusic(music1) does not work and the music never plays. Is there a way to get the music to play other than loading it as a separate music file?

( I'm really bad at this )

Please specify:
1)When does it freeze? Does it freeze immediately upon starting the script? Is there an error message? Please post the entire script, not just what is after @Finalize. How you call mainTask is also important (if you call it during @MainLoop, I suspect overflow to the point of crashing or maybe even infinite recursion; I haven't looked at the code very carefully), and knowing about how you call the tasks may result in a faster understanding of the problem.
2) What kind of script is this? Stage enemy? Boss? (I assume boss)

Sorry, entire code--->http://pastebin.com/RMjst9Py
It freezes when I start playing it, there is no error message, and it's a boss script.

Qwerty: Your #TouhouDanmakufu needs a [Single], assuming it's a single pattern. That would fix the crash probably, but it would still error.

Firstly, you don't need to put SetMovePosition inside the loop. As it is, it's running SetMovePosition every frame which is sort of redundant if the boss is already at that position. It wouldn't cause an error, but you only need to call it once. while(Obj_BeDeleted(obj)==false){  yield;  } is redundant too. It won't do anything extra besides extra empty processing.

task fire(GetEnemyX, GetEnemyY, 2, GetAngleToPlayer): You do not put your parameters in the function declaration, you put them when you call the function. But considering you put the exact same things (GetAngleToPlayer etc) in the function itself rather than using any actual parameters, you don't even need any parameters for the function.

Here is that last part fixed: http://pastebin.com/w4H6Uv9H


Sparen: You have to Delete and reload.

You mean DeleteMusic(music1) INSIDE the task stage? (see asterisks)

Code: [Select]

task Stage{
    wait(1); //Required to be here, greater than 0.
    PlayMusic(music1);
    CreateEnemyBossFromFile(section1, GetCenterX, 0, 1.4, 90, 0);
    WaitForZeroEnemy; //MANDATORY or the rest of the code will never be executed!!!
    wait(60);
    CreateEnemyBossFromFile(section2, GetCenterX, 0, 1.4, 90, 0);
    WaitForZeroEnemy;
    FadeOutMusic(music1, 30); //3 seconds to fade out
    wait(120);
    *DeleteMusic(music1);
    Stage1;
    *LoadMusic(music1);
    wait(120);
    PlayMusic(music1);
    CreateEnemyBossFromFile(section4, GetCenterX, 0, 1.4, 90, 0);
    WaitForZeroEnemy;

...Yes. If you had time to write that out did you not have time to test it?

[Sparen]

Just wanted to confirm beforehand because I though that you could only use DeleteXYZ in @Finalize and LoadXYZ only in @Initialize.

Anyway, it worked.

[Sparen]

Back to an older question that I thought was solved until I found an exception.

Code: [Select]

task checkdeath{ //Added Jan 9 and removed stuff from Missed
    loop{
      if(OnMissed){
        loop(GetRebirthFrame){ //Orig: GetRebirthFrame+60. @Missed runs 75 times.
  if(IsLastSpell){LS = 1;} //To keep your Veetype
  yield;
}
        if(LS==0){
  veetype = 0;
          SetSpeed(3.5,1);
          }
        LS = 0;
      }yield;}}The code is supposed to preserve veetype if you death bomb. LS == 0 refers to a normal death, LS == 1 refers to a death bomb. If you die normally, you technically should return to veetype = 0. but that apparently doesn't happen. The code is called in @Initialize and is set in an infinite loop (without building the stack). I collapsed parts of the task that aren't important.

Basically, I want to find out why either

Code: [Select]

if(IsLastSpell){LS = 1;} or

Code: [Select]

if(LS==0){veetype = 0; SetSpeed(3.5,1);} doesn't work.

This question isn't much of a problem, more of a "how to" question.  :3
What I want to know is how do I insert a custom STG Frame in danmakufu. This might seem like a lot for a question though. Or you can just give me a script that tells danmakufu to insert an STG Frame.
I have many danmakufu games but I can't find the scripts containing the STG Frames. This would help a lot to me. Hopefully this is not too much trouble.  :ohdear:

[Sparen]

@Lavalake: http://www.bulletforge.org/u/shockman/p/mima-boss-battle/v/12
It's the featured project on BulletForge. XD.

The below is the frame task from Shockman's script. You should be able to understand most of it; otherwise you can look at the Danmakufu Wiki's function list.

Code: [Select]

task stgframe{
let obj=Obj_Create(OBJ_EFFECT);
Obj_SetX(obj,0);
Obj_SetY(obj,0);
ObjEffect_SetLayer(obj,8);
ObjEffect_SetRenderState(obj,ALPHA);
ObjEffect_SetTexture(obj,frame);
ObjEffect_SetPrimitiveType(obj,PRIMITIVE_TRIANGLEFAN);
ObjEffect_SetScale(obj,1,1);
ObjEffect_SetAngle(obj,0,0,0);
ObjEffect_CreateVertex(obj,4);
ObjEffect_SetVertexUV(obj,0,0,0);
ObjEffect_SetVertexUV(obj,1,640,0);
ObjEffect_SetVertexUV(obj,2,640,480);
ObjEffect_SetVertexUV(obj,3,0,480);
ObjEffect_SetVertexXY(obj,0,0,0);
ObjEffect_SetVertexXY(obj,1,640,0);
ObjEffect_SetVertexXY(obj,2,640,480);
ObjEffect_SetVertexXY(obj,3,0,480);
yield;}Basically, you have a frame matching Danmakufu's window coordinates, with a massive empty transparent space where the action takes place, and you just run the task in @DrawLoop.

Hope it helps.

I'm having trouble with the stage and familiar part...I create 2 familiars for the stage and when I shoot one, the picture of the other one goes away, but is still there.

Ahh. I had this similar question a while ago.
Did you put "DeleteGraphic" in Finalize?
You shouldn't do that if you have multiple of the same enemies since it just makes the graphics disappear until another "LoadGraphic" activates. But by then, most of the familiars' scripts will have bypassed the "LoadGraphic" in their scripts.
In short, don't DeleteGraphic when your making familiars for a stage. :3

Thanks! :D I read the message after I figured it out though xD
Anyway, do you know how to make my familiars shoot?  :)

In the while(!Obj_BeDeleted) statement, add whatever you need.

Obj_GetX(obj)
Obj_GetY(obj)
Obj_GetAngle(obj)

etc. will help you do what you need to do.

I'm a little confused, are we talking about object bullets or familiars?

Basically, bosses are like the main familiars of each stage. If you know how to shoot with bosses, familiars would be easy to script.
So you can just use CreateShot01, Object bullets, etc.
Unless you're talking about Player Familiars(The ones for a player script.)? Those are more complex with scripting.

Tried that and it either freezes or doesnt shoot bullets. No it isn't a Player Familiar either.

[Lavalake]

Hmm. Can you post the script on pastebin.  :3 I need to find what the matter is in the script.

[Sparen]

I did not know if you were using object familiars or if you were using familiars that were loaded like stage enemies. I assume now that you are using the latter, in which case you run the script like a normal enemy or boss attack. Fill in your variables, then fill in MainLoop or whatever tasks you are going to be using.

And yes; definitely post the code so that we have an idea of what is going on.

You never called MainTask in @Initialize of your familiar script. That's why it doesn't shoot. Also, a speed of 7, along with 12 bullets per second, is extremely hard to dodge is you aren't streaming or if there are other bullets.
