Hi,
I want to do spray paint effect,but how to cancel the point of the drip effect? (just want only "line "drip)
sorry,I just the beginner.
thanks!!
my code:
```auto
final int maxIterations = 20; //
float x=0;
float y=0;
void setup () {
size (500, 700);
background(255);
stroke(0); // red
}
void draw () {
if (mousePressed ) {
brush () ;
brushX();
}
}
void brush () {
int width1=40; //
//
float radx; // Radius
float rady;
float angle1; // angle
float x; // result
float y;
//
for (int i=0; i < maxIterations; i++) {
radx=random(width1);
rady=random(width1);
angle1= random(600);
//
x=(radx*cos(radians(angle1)))+mouseX;
y=(rady*sin(radians(angle1)))+mouseY;
strokeWeight(3);
point(x, y);
}
}
void brushX () {
int x=0;
int y=0;
for (int i=0; i < 2; i++) {
x=mouseX;
y=mouseY;
strokeWeight(2);
line(mouseX,mouseY,mouseX,mouseY++);
}
}
```

Ummm, could you try to rephrase your problem? I don’t understand what you’re trying to achieve… are you trying to create a spray paint effect from scratch? or are you using some library?
maybe you could find some help [here](https://discourse.processing.org/t/guidelines-asking-questions/2147/9) on how to make your question more understandable.

please remember
- to use ctrl-t in pocessing to get auto-format before posting
- after you pasted your code: in the forum select your code with the mouse and hit ctrl-e (or in the small command bar the sign ``)
- to use more empty lines, between functions for example
Hey, and welcome to the forum!
Warm regards,

Hello KaliBrain,
thanks for your reply!
I want to make a spray paint effect,and partly completed.
It will dripping if I press the mouse for more than 3-5 seconds,but how to cancel the splashing effect for the dripping?
Thanks!!
my code:
```auto
final int maxIterations = 20;
float x=0;
float y=0;
void setup () {
size (500, 700);
background(255);
stroke(0);
}
void draw () {
if (mousePressed ) {
brush () ;
brushX();
}
}
void brush () {
int width1=40;
float radx;
float rady;
float angle1;
float x;
float y;
for (int i=0; i < maxIterations; i++) {
radx=random(width1);
rady=random(width1);
angle1= random(600);
x=(radx*cos(radians(angle1)))+mouseX;
y=(rady*sin(radians(angle1)))+mouseY;
strokeWeight(3);
point(x, y);
}
}
void brushX () {
int x=0;
int y=0;
for (int i=0; i < 2; i++) {
x=mouseX;
y=mouseY;
strokeWeight(2);
line(mouseX, mouseY, mouseX, mouseY++);
}
}
```

Hello,
This is useful for timing:

There are many examples of timers in this forum.
I created a “rough” dripping effect with circle() and random() using mouseReleased():
```auto
void mouseReleased()
{
x = mouseX;
y = mouseY;
// Add code for effect here
}
```
Have fun!
`:)`

I was thinking maybe you could use some sort of statement including the `dist(mouseX,mouseY,pmouseX,pmouseY)` function.
Another good option is using a statement including time elapsed like @glv suggested.
About the fact that the dripping effect had a spray effect too, maybe it’s because of too little variables and the fact that the same variable controls the spray effect and the line effect. I didn’t read into your code fully as it was kind of long, but I hope you find a solution and send the fixed code here as I would be interested in seeing it.
GL!

You change mouseY
That’s not a good thing
Instead copy mouseY to a new variable when dripping starts and then work with the new variable
