int function for a line

honzojd

Hello I would like to define one line (for example as a X) and then just use X when needed. I would like to have something like this:

int x = in.right.get(i)*30; vertex(207+x,227+x);

is there some way please?

Chrisir

you can write a function and use this function from draw()

lineMyOwn (int x) {
    line(207+x, 222, 
           227+x, 290); 
}

Or you can use translate beforehand.

pushMatrix();
translate(x,0);
line(207,222,227,290);
popMatrix();

when you use minim :

void LineForMinim(int i) {
 int x = in.right.get(i)*30;
 vertex(207+x,227+x);
 line (207+x, 120, 227+x, 120);


}

The last one you sent (Chrisir) seems nice, but actualy it's not working for me :/ it says unexpecting void.. but i would love solution like this

Chrisir

Sounds like a missing } somewhere

Could you post your entire code please ...?

import ddf.minim.*;

void setup;{
size (900,900)

void LineForMinim(int i) {
 int x = in.right.get(i)*30;
 vertex(207+x,227+x);
 line (207+x, 120, 227+x, 120);
}
}

There are several issues:

• You have a ; instead of () after setup.

• functions have to be outside of other functions.

• You do not initialize minim and do not define in.

The following example shows only the structure, i am not sure if i understood what exactly you wanted to do.

// imports
import ddf.minim.*;

// variables
Minim minim;
AudioInput in;

void setup(){
  size(200, 200);
  // initialize minim
  minim = new Minim(this);
  // initialize input-channel
  in = minim.getLineIn();
}

void draw(){
  // draw background
  background(200);
  // use a custom function
  ellipse(width/2, height/2, scaledInputLevel(), scaledInputLevel() );
}

// own functions have to be outside of setup() or draw()
float scaledInputLevel() {
  return in.mix.level()*200;
}

I want to simplify this:

bezierVertex(1202,90,1285,186,1285+in.left.get(i)*50,430+in.right.get(i)*50);

because sometimes I would like to give this dynamic value to every number. It uses Minim

you HAVE to learn to post code correctly. nobody can make sense of that mangled garbage.

paste the text
highlight the text
press ctrl-o

that's all it takes.

oof! rejected answer. i'm trying to help.

look at how your code appears up there. does it match what you pasted? no. what's there is just a syntax error. this is because you haven't marked it as code.
