hello,

that's nice!

I give you some sources and you can make a first sketch from them.

for movement see
http://processing.org/learning/topics/bounce.html

for cursor see
http://processing.org/reference/keyCode.html

the keys are called UP DOWN LEFT and RIGHT

you have to combine the two codes.

Let's say the ball is your player.
You don't want to let it move by itself but rather command it by cursor keys.

You have to check for all 4 cursor keys in the second code.

in the function keyPressed please change

xdirection  // Left or Right // when RIGHT it must be +1, LEFT -1
ydirection  // Top to Bottom // when UP it must be -1, DOWN +1

Greettings, Chrisir   

of course you must know what setup and draw and if is.

Did you read the first three articles here

Thank you very much! :)

do you have a labyrinth already?

You can e.g. think of the labyrinth as a grid: each cell can have a brick or a path


you can get the pixel col with get:

http://processing.org/reference/get_.html

you can check whether the next pixel ahead is black or not:

1. color nextPixel = get ( xPos , yPos + 3 );

you can write this if-statement in the function draw()

if it is true, he dies.

Yeah, I know, but I don't really understand how I use the pixel get () reference. All I'm writing doesn't work and I'm getting desperate. I just want this to work :(

that would make you a new variable with the name nextPixel(choose any name you want) and
fill it with the color of the pixel at position xPos , yPos + 3

you could also say in draw()

1. color nextPixel = get ( xPos, yPos );
2. // if player is in black area
3. if (nextPixel == color (0)) {
4.     heDied=true;
5. }

with this before setup()

1. boolean heDied = false;

Sadly that doesn't work for my picture. Can I use a png picture? I typed the text as you wrote it, but it doesn't work. What could i have done wrong?

you have to check whether your black is really
color(0)
otherwise try

and check the value

against a threshhold
