This is my sketch. unfortunately, it doesn't work like it should. so the question: does anyone know how to connect the green brush tool (which should work also in the foreground of the landscape) with the landscape (the landscape is used to change whenever the "l" key is pressed, but that only works when the brush tool is uncommented)?

also, every time i use the brush tool, the clouds dont have a stroke anymore...i dont know how to prevent that...

please, someone help me! i would be so relieved!!!!!!

THANK YOU! =)

void setup() {

smooth();

size(840, 460);

background(160, 230, 220);

}

int seed = 0;

void draw() {

if(mousePressed){

for (int i=0; i<140; i+=1) {

strokeWeight(0.3);

fill(random(030),random(0,20),250,2);

ellipse(mouseX+random(0,30),mouseY+random(0,40),random(20,80),random(30,60));fill(0,0,250,90);

}

// noStroke();

// float x2 = width/2+ sin(frameCount/90.0)*250;

// float y2 = height/2+ cos(frameCount/90.0)*250;

// for (int i=0; i<140; i+=1) { //sonne

// fill(250, 226, 10, 255-(255/50)*i+100);

// ellipse(x2, y2, 40+i, 40+i);

// }

//}

if(keyPressed){

if(key=='r'){

//green brush

noStroke();

fill(random(20,35),random(49,59),36,50);

if(key=='r')ellipse(mouseX,mouseY,40,40);

}

void keyPressed() {

if(key=='b'){

randomSeed(seed);

//landscape

strokeWeight(2);

float noiseScale=0.009;

for ( int i=100;i<222;i+=30) {

fill(183-((183-23)/120)*i, 135-((135-124)/120)*i, 252-((252-19)/120)*i);

float rand=random(random(300));

beginShape();

vertex(0, height);

for (int x=0; x < width; x++) {

float noiseVal = noise((rand+x)*noiseScale, rand*noiseScale);

vertex(x, noiseVal*90+i/3+height/2-60);

}

vertex(width, height);

endShape();

}

seed++;

you set noStroke(); when key == 'r' so the stroke is never re-established.

As a quick fix: what jas0501 said.

But generally I'm a bit confused and am still trying to find out what exactly you want to do in your sketch. Currently I'm thinking it's the following interactions:

"b" generates a landscape.
"c" and "r" toggle between drawing clouds and green ellipses. (Should having the mouse pressed continuously draw these elements or should they just draw once on mouseclick?)
clouds/green draw on top of the landscape.
there's a sun, doing it's rounds. I'm guessing the sun should go behind the landscape.

Are these assumptions correct? It always helps to have a clear picture of what the different elements are and how they should behave.

yes, thats right! (i didnt speak english for a while, so i am out of practice...but i think you understand me anyway :P)

pressing "c" and having the mouse pressed continuosly, draws clouds. just the same with pressing "r" and having the mouse pressed continuously to get the green brush.

the clouds dont have to be in the foreground, but the green brush has to...;)

yes, the sun...i dont know...the sun isnt such important, i uncommented that part because it doesnt work since i added the clouds (i had to remove the background because otherwise, the brushes didnt work :D...

thank you for your comment! =)

You need to learn how to layout your code. Even experienced programmers would not be able to look at the above code and make sense of what you have done. I have taken your code and removed excessive blanks lines and used the auto format option on the Edit menu in Processing to tidy up your code.

This is what I got.

int seed = 0;
void setup() {
smooth();
size(840, 460);
background(160, 230, 220);
}
void draw() {
if (mousePressed) {
for (int i=0; i<140; i+=1) {
strokeWeight(0.3);
fill(random(030), random(0, 20), 250, 2);
ellipse(mouseX+random(0, 30), mouseY+random(0, 40), random(20, 80), random(30, 60));
fill(0, 0, 250, 90);
}
}
if (keyPressed) {
if (key=='r') {
//green brush
noStroke();
fill(random(20, 35), random(49, 59), 36, 50);
if (key=='r')ellipse(mouseX, mouseY, 40, 40);
}
}
}
void keyPressed() {
if (key=='b') {
randomSeed(seed);
//landscape
strokeWeight(2);
float noiseScale=0.009;
for ( int i=100;i<222;i+=30) {
fill(183-((183-23)/120)*i, 135-((135-124)/120)*i, 252-((252-19)/120)*i);
float rand=random(random(300));
beginShape();
vertex(0, height);
for (int x=0; x < width; x++) {
float noiseVal = noise((rand+x)*noiseScale, rand*noiseScale);
vertex(x, noiseVal*90+i/3+height/2-60);
}
vertex(width, height);
endShape();
}
seed++;
}
}

I do not understand the explanation of the first problem, the landscape changes with the b key.

The second problem is easier to explain.

every time i use the brush tool, the clouds dont have a stroke anymore.

When you press the r key the code in lines 20-23 are exucuted. The first line is noStroke() this will turn off the stroke until re-enabled with the stroke() command (it is NOT re-enabled with the strokeWeight() command).

I suggest that where you have used the strokeWeight you also add the stroke command i.e.
stroke(0);
This will set the stroke to black.

THANK YOU very much for your help! =)

as you could see, i am an absolute beginner...;)

but now, the stroke is back. i didnt know that strokeWeight doesnt bring back the stroke :D
