Cheat Sheet

Shapes & Drawing:

These are some basic shapes used for most projects, as well as some other useful Processing-specific things Feel free to check the processing reference for other shapes.

    background(red, green, blue); //set the background color, use at the beginning of draw()

    triangle(x1, y1, x2, y2, x3, y3);
    rect(x, y, height, width);
    circle(x, y, diameter);
    line(x1, y1, x2, y2); 

Control:

    if(condition){
        //run some code
    } else if(condition){ //OPTIONAL
        //run some different code
    } else { //OPTIONAL
        //run some different code
    }

    while(condition){
        //some code to run over & over
    }

General Syntax:

---

//This is a comment, it’s written with the code, but not run

exampleFunction(); //All lines end with a “;”

void exampleFunction() {  } //or a “{“

exampleNameMultipleWords(); //use camelCase (nameThingsLikeThis, dont_use_spaces, DontCapitalizeTheFirstWord)

if(condition){          //This example is meant to show
    while(condition){   //correct indentation. After a { you
        rect(10,10,10,10); // should always indent and before
        circle(1,2,3);  // a } you should always unindent.
    }
    clear();
}
line(1,3,5,7);
