Stuffman's code for the right wall

Ugh...  Can anyone tell me exactly how Shot replacement works? I can't seem to find anything on it...

[Demonbman]

Shot Replacement works by using #include_function "pathname of .txt" to make it easier to catorgorize shots.

when making Shot Data you give the bullets an ID, calling this ID calls that bullet's graphic with the ID of the one called, but it is possible to "replace" this ID with something easier, such as RED01, BLUE02, GREEN22 etc. etc.

Does that clear that up?

[空SoraのNo鏡Kagami]

I think what i was trying to say was... How would you put it into the code... It confuses me,,,

[Demonbman]

you would use

#include_function"pathname to the shot_replace.txt"

it doesn't have to be named shot_replace.txt, but thats just an example

[Zerro]

Gargh! I'm still confused!


GetPlayerScriptName and USER_PLAYER confuse me to no end. 
How do you use them? How do you use them for multiple characters?

[Demonbman]

GetPlayerScriptName works by getting the name of the player script that the player is currently using.
for example
if(GetPlayerScriptName == enter_name_of_player.txt){ SetStuff; DoStuff; Whatever;}
note, that you will need to know the name of the player script before hand.

USER_PLAYER, I have no idea what that does

[Chronojet ⚙ Dragon]

USER_PLAYER, I have no idea what that does

USER_PLAYER is for a Player Script, for example, "Rumia.txt"

[Zerro]

GetPlayerScriptName works by getting the name of the player script that the player is currently using.
for example
if(GetPlayerScriptName == enter_name_of_player.txt){ SetStuff; DoStuff; Whatever;}
note, that you will need to know the name of the player script before hand.

USER_PLAYER, I have no idea what that does

Thanks, it's working now ^_^

How to make screen Shake  ? Like when you use master spark

How to make screen Shake  ? Like when you use master spark

There is a command in danmakufu that does that, but I believe it screwed up replays and various other things.

So you best bet is to make every bullet an object bullet (not effect object, what was I thinking when I wrote that?!), then declare a global angular variable that gets set to a random angle each 3 frames or so and have each bullet, the player and the bullets move in the direction of that variable.

To prevent the shaking from occasionally drifting everything in one direction, I'd advise to use shakeangle+=rand(120, 240); for the shaking randomization.

Hey,
I'm very new to Danmakufu and I have a problem with my @BackGround loop.
I started making my first boss some weeks ago with my first spellcard.
In this spellcard my background image shows up just fine.(It is a placeholder btw...I'm still looking for other bg pictures)
After I finished this spell I decided to make a non-spell like a prequel and to combine these scripts in a plural script.
I copied the whole code and delete some things like SetScore and CutIn but I didn't change any variablenames or values or code in the @DrawLoop or the @BackGround loop.
But the graphics (both bg and enemygraphics) didn't work anymore.
I was able to get the enemygraphics to work again through recoding it completely and changing some things, but I couldn't get the bg to work. (It just shows the standart bg in Danmakufu)
Is there a bug in Danmakufu, which causes the Graphicfunctions to screw up, when you use them in a single script without calling SetScore and/or CutIn or did I make a mistake?

Some code:

At first the @DrawLoop from the first, real spellcard (I left out the variables, because the values didn't change and I checked them three times):

    @DrawLoop {                     
         
         SetTexture(imgBoss);
         SetRenderState(ALPHA);
         SetAlpha(255);
         SetGraphicScale(0.6,0.6);
         if(int(GetSpeedX())==0) {
            if(f<=10)         { SetGraphicRect(0,0,35,120); }
            if(f>10 && f<=20) { SetGraphicRect(39,0,74,120); }
            if(f>20 && f<=30) {SetGraphicRect(78,0,113,120); }
            f2=0;
         
         
         }
         
         if(GetSpeedX()>0) {          
         
            if(f2<=5)         { SetGraphicRect(170,0,220,120); }
            if(f2>=5) { SetGraphicRect(222,0,279,120); }
            f2++;
         
         
         
         }
         
         if(GetSpeedX()<0) {            
            SetGraphicAngle(180,0,0);
            if(f2<=5)         { SetGraphicRect(170,0,220,120);
            DrawGraphic(GetEnemyX, GetEnemyY);
                                                            }
            if(f2>=5) { SetGraphicRect(222,0,279,120);
            DrawGraphic(GetEnemyX, GetEnemyY);
                                             }
            
            f2++;
         
         
         
         }
         
         
         
         
         
         
         
         
         
         DrawGraphic(GetX,GetY);
         
         f++;
         if(f == 30){f=0;}
   
   
   }

   
    @BackGround {                  
   
         SetTexture(bg);
         SetRenderState(ALPHA);
         SetAlpha(255);
         SetGraphicRect(0,0,500,333);
         SetGraphicScale(1,1);
         SetGraphicAngle(0,0,0);
         DrawGraphic(GetCenterX, GetCenterY);
      
   }

Now the code from the "prequel-non-spell" (How do you call it??):

  @DrawLoop {                     
         
         SetTexture(imgBoss);
         SetRenderState(ALPHA);
         SetAlpha(255);
         SetGraphicScale(0.6,0.6);
         if(int(GetSpeedX())==0) {
         SetGraphicAngle(0,0,0);
            if(f<=10)         { SetGraphicRect(0,0,35,120); }
            if(f>10 && f<=20) { SetGraphicRect(39,0,74,120); }
            if(f>20 && f<=30) {SetGraphicRect(78,0,113,120); }
            f2=0;
         
         
         }
         
         if(GetSpeedX()>0) {          
         SetGraphicAngle(0,0,0);
            if(f2<=5)         { SetGraphicRect(170,0,220,120); }
            if(f2>=5) { SetGraphicRect(222,0,279,120); }
            f2++;
         
         
         
         }
         
         if(GetSpeedX()<0) {         
            SetGraphicAngle(180,0,0);
            if(f2<=5)         { SetGraphicRect(170,0,220,120);
            DrawGraphic(GetEnemyX, GetEnemyY);
                                                            }
            if(f2>=5) { SetGraphicRect(222,0,279,120);
            DrawGraphic(GetEnemyX, GetEnemyY);
                                             }
            
            f2++;
         
         
         
         }
         
         
         DrawGraphic(GetX,GetY);
         
         f++;
         if(f == 30){f=0;}
   
   
   }

   
    @BackGround {                  
   
         SetTexture(bg);
         SetRenderState(ALPHA);
         SetAlpha(255);
         SetGraphicRect(0,0,500,333);
         SetGraphicScale(1,1);
         SetGraphicAngle(0,0,0);
         DrawGraphic(GetCenterX, GetCenterY);
      
   }

As you can see, I had to change the code in the @DrawLoop to get it work properly. How do I get the background to work?


My apologies for my bad english. I'm german and I learned it at school...

Grums

[Demonbman]

@BackGround does not work in Non-Spells, @BackGround only functions when there is SetScore. Copy Paste everything in @BackGround and put it in @DrawLoop

[Foremoster]

There is a command in danmakufu that does that,

Just for fun what's the command though  :V ?

[Grumskiz]

Thanks a lot Demonbman.
Now the background works also in non-spells.
But why do I need to change the code in the Drawloop? Also because my script has no SetScore?
Thats pretty annoying for those who want to create their own bosses in Danmakufu   

[Demonbman]

Well, most people use Stage Scripts to host the background. And yes, @BackGround is IGNORED when there is no SetScore

[Grumskiz]

Damn I knew it would happen...my english sucks -.-
My last question was intended to be like this one, but I messed it up, so you understood it wrong (I don't blame you...it was my fault):
Why did I also have to change the code for the bossgraphic (not the background) in the Drawloop?

I have no idea why you would have to do that, unless you had two variables, or you used the same variable twice, I see no reason why you would have to do that.

HOW DO I MAKE A FAMILAIR FOR MY GAME CHARACTER!?
 :3

[Demonbman]

Didn't you read the sticky? Look for Stuffman's Player Tutorial, he has it explained in there

[ganon2310]

i did and he assumed that we already knew how to make and option. i dont.

[Demonbman]

5th Code Box from the post, look at it, it even says optionX and optionY for your convience.

[electron9186]

Ganon, i know you're basing your character somewhat off the tutorial's Sakuya A, so here's some hopefully relevant code. It's the option task from the script. Modify as neccessary.

Code: [Select]

task Option(position){
let objoption=Obj_Create(OBJ_EFFECT);
Obj_SetAlpha(objoption,200);
ObjEffect_SetTexture(objoption,img_sakuya);
ObjEffect_SetRenderState(objoption,ALPHA);
ObjEffect_SetPrimitiveType(objoption,PRIMITIVE_TRIANGLEFAN);
ObjEffect_CreateVertex(objoption,4);
ObjEffect_SetVertexUV(objoption,0,145,1);
ObjEffect_SetVertexUV(objoption,1,159,1);
ObjEffect_SetVertexUV(objoption,2,159,15);
ObjEffect_SetVertexUV(objoption,3,145,15);
if(position=="LEFT"){
while(!Obj_BeDeleted(objoption)){
ObjEffect_SetVertexXY(objoption,0,GetPlayerX-optionxpos-8,GetPlayerY+optionypos-7);
ObjEffect_SetVertexXY(objoption,1,GetPlayerX-optionxpos+6,GetPlayerY+optionypos-7);
ObjEffect_SetVertexXY(objoption,2,GetPlayerX-optionxpos+6,GetPlayerY+optionypos+7);
ObjEffect_SetVertexXY(objoption,3,GetPlayerX-optionxpos-8,GetPlayerY+optionypos+7);
if(GetKeyState(VK_SLOWMOVE)==KEY_PUSH || GetKeyState(VK_SLOWMOVE)==KEY_HOLD){
if(count%6 == 3){
JackTheRipper(GetPlayerX-optionxpos-1,GetPlayerY+optionypos-8,12);
}
}else{
if(count%8 == 4){
i=-2;
while(i<=2){
CreatePlayerShot01(GetPlayerX()-optionxpos-1, GetPlayerY()+optionypos-8, 10, 254+(i*8), 1.5, 1, 2);
i++;
}
}
}
yield;
}
}else{
while(!Obj_BeDeleted(objoption)){
ObjEffect_SetVertexXY(objoption,0,GetPlayerX+optionxpos-7,GetPlayerY+optionypos-7);
ObjEffect_SetVertexXY(objoption,1,GetPlayerX+optionxpos+7,GetPlayerY+optionypos-7);
ObjEffect_SetVertexXY(objoption,2,GetPlayerX+optionxpos+7,GetPlayerY+optionypos+7);
ObjEffect_SetVertexXY(objoption,3,GetPlayerX+optionxpos-7,GetPlayerY+optionypos+7);
if(GetKeyState(VK_SLOWMOVE)==KEY_PUSH || GetKeyState(VK_SLOWMOVE)==KEY_HOLD){
if(count%6 == 3){
JackTheRipper(GetPlayerX+optionxpos,GetPlayerY+optionypos-8,12);
}
}else{
if(count%8 == 4){
i=-2;
while(i<=2){
CreatePlayerShot01(GetPlayerX()+optionxpos, GetPlayerY()+optionypos-8, 10, 286+(i*8), 1.5, 1, 2);
i++;
}
}
}
yield;
}
}
}

electron, how do i test if it worked?
 :3

[electron9186]

Good question. I don't think we'll be able to even get your character to work until we code the rest of the nonsense for its file.

This is going to take a while... 

[GenericTouhouFailure]

Stupid question: Does Obj_SetSpeed and Obj_SetAngle work for obj Effects?

[Chronojet ⚙ Dragon]

Stupid question: Does Obj_SetSpeed and Obj_SetAngle work for obj Effects?

I'm not sure about Obj_SetSpeed, but I'm sure ObjEffect_SetAngle is supposed to be used instead for effects.

[Azure Lazuline]

ObjEffect_SetAngle changes the angle of the graphic, while Obj_SetAngle changes the angle of movement. Yes, Obj_SetSpeed works with effect objects.

[GenericTouhouFailure]

ObjEffect_SetAngle changes the angle of the graphic, while Obj_SetAngle changes the angle of movement. Yes, Obj_SetSpeed works with effect objects.

Thanks.

Now if I want my effect object to hurt the player should I use SetCollisionB or what?

[Iryan]

Thanks.

Now if I want my effect object to hurt the player should I use SetCollisionB or what?

if( ( (GetPlayerX-Obj_GetX(obj))^2 + (GetPlayerY-Obj_GetX(obj))^2 )^0.5 < radius of the object){ CreateShot01(GetPlayerX, GetPlayerY, 0, 90, WHITE05, 0); }


Or something like that.
