Doublepost, bitches.

How does @Background work and what functions can be passed in it?

[Stuffman]

Functionally I'm pretty sure @Background is exactly the same as @DrawLoop, except in terms of priority. @Background is executed before @DrawLoop so anything you draw in it will be below all other graphics. Also, I think @Background might have less priority in terms of processor power? When I hit the fast forward key the background doesn't move as fast as the play field, or something like that.

@Background is really more for organization purposes, clarifying what's stage graphics and what's character graphics. It's also unusual to use @Background in a spellcard script, as making a background in a stage script will pass it to any spellcards.

[Helepolis]

It's also unusual to use @Background in a spellcard script, as making a background in a stage script will pass it to any spellcards.

What if you want to change the background after a few spellcards, like with Marisa's/Reimu's IN "running away". CommonData?

[Stuffman]

Well in IN's case it would actually be easy because technically the first part of the fight is a midboss, since it ends and you go into normal stage mode again; you would just set a variable in the stage script at that point to make the background behave differently.

If you wanted to change the background in the middle of a plural file though...well personally I would just use commondata for the stage @Background to reference, but yeah you could put a special background into the spellcard. Though that does raise the question to me, will spellcard @Background positions carry over between spellcards or will they reset each time a new attack comes up? I would assume they don't so that's another reason to save @Background for the stage script.

[Naut]

I asked because I can't draw text in @Background for a stage script. Thought it might be different.

[Demonbman]

is there a way to make a bullet start at..lets say x=200, is there a way i can like make it fire +10 every time? so it would first fire at 200, then 210, 220, 230...and so on an so on?

ascent(i in 0..10){
    CreateShot01(200+(i*10), 0, 3, 0, RED01, 5);
}

add pauses and such

[Henry]

Can anyone tell me about how to make Talking events in Danmakufu, is the 'yield;' statement required? (i'm totally lost)

[Naut]

Hello Henry.

However, this script is non-functional (boss image won't display)

You have two dots in your main folder locator thingy. It's not "..\etc", it's ".\etc".

I believed that .\ and ..\ are the same, and it worked for my other scripts (using the same images and resources in the same folder)

Oh, I mean the text displayed by #PlayLevel[blah blah blah].

Is it changable mid-game?

Midscript I guess not, but you could have a stage script with multiple spellcard scripts in it, and have different #PlayLevel strings for each spellcard or something.

[Henry]

Yuo misspelt to yield; into yeild; in the @MainLoop and a } is missing.

[Drake]

It would help if you at least looked at your script instead of just coming here going "oh no it doesn't work immediately"

"yield" is spelled wrong in the MainLoop, and should be called every frame, not just at 60.
Also, you're missing a } at the end of your script.

[Henry]

Btw, after frame==10, you set frame=0.
Then the if(frame==60){} can never be run.

The enemy is displayed but the event doesn't end. The whole plural script stucks there. Why?

[Helepolis]

The enemy is displayed but the event doesn't end. The whole plural script stucks there. Why?

Your dialogue file is setup terribly wrong

1) Give the boss 1 or 10 life.
2) Remove that End(); line. It is wrong.
3) In the 'event_script' section set the following line where you want the dialogue to end and the fight to start:  SetStep(x);  where x is a number. Example: SetStep(1); ( multiple steps are possible ).
4) In the 'enemy_script_main' set an if-statement listening to the step. if(GetEventStep==1){AddLife-50;}

So what happens here? The dialogue is spoken and SetStep is set to '1'. In the MainLoop, the statement will become true, thus it will subtract 50 life off the boss. The boss is 'killed' and the next line in the plural script is called.

Your plural script should also look like this:
#ScriptPath[.\Dialogue01.txt]  <--- Dialogue
#ScriptPath[.\Noncard01.txt]
#ScriptPath[.\Spellcard01.txt]
#ScriptNextStep
..

See my Afro boss which is done excactly the same.

( ps didn't I explained you this before somewhere on page 17 or so ? )

[Henry]

The problem is finally solved...

(It seems that it was not me and I didn't intend to make a talking script as I did not even know about yield;)

Thank, Helepolis

[Kylesky]

I have a question... how do you make the screen shake? like when minamitu murasa's anchors hit the edge of the screen... tnx in advance

[Suikama]

My guess is you have to basically redraw everything; the background, the boss, the player, etc. I'm not sure how you would get the bullets to shake unless you used object bullets or something... But yeah if you tried it this way it would take ages.

[Chronojet ⚙ Dragon]

I have a question... how do you make the screen shake? like when minamitu murasa's anchors hit the edge of the screen... tnx in advance

Code: [Select]

let variable = 0;
let shakeboolean = false;
let xshake = 0;
let yshake = 0;

...

@Initialize {
...
LoadImage("script\img\thisistheimage.png");
...
}
@MainLoop {
...
if(insert some conditions here) {
shakeboolean = true;
} else {
shakeboolean = false;
}
if(shakeboolean == true) {
statements to alter xshake and yshake;
} else {
xshake = 0; yshake = 0;
}
...
}

...

@BackGround {
SetTexture("script\img\thisistheimage.png");
SetGraphicRect(left, top, right, bottom);
otherstuff;
DrawGraphic(x-coordinate to put the center of the image + xshake, y-coordinate to put the center of the image + yshake);

I think... 

[Suikama]

That would only make the background shake, not the whole screen.

[Kylesky]

Thanks! even though it's only making the background shake... I think I could use this... I don't really need the other things to shake anymore...
