Hello guys, I need help for a processing project.
Here my code:
When i shoot with tail the ball do not go straight and make a curve. I want to stop the ball

Thanks !

Here my code to stop the ball. But he don’t work

if(vell.x > 0 && vell.x != 0){
    CoeffFrictionX = 0.1D;
    vell.x -= CoeffFrictionX;
    println("Vell x " + vell.x);
  }else if(vell.x < 0 && vell.x != 0){
    CoeffFrictionX = -0.1D;
    println("Vell x " + vell.x);
    vell.x -= CoeffFrictionX;
  }
  
  if(vell.y > 0 && vell.y != 0){
    CoeffFrictionY = 0.1D;
    println("Vell y " + vell.y);
     vell.y -= CoeffFrictionY;
  }else if(vell.y < 0 && vell.y != 0){
    CoeffFrictionY = -0.1D;
    println("Vell y " + vell.y);
     vell.y -= CoeffFrictionY;
  }

wow, i like that.
-a- but the corner holes position is not symmetric
-b- much more work on the border / bounce needed.

your ball stop
just a idea:

double CoeffFriction=0.98D;

void stoping_ball() {
  if (vell.x > -0.1 && vell.x < 0.1) vell.x = 0;
  else vell.x *= CoeffFriction;
  if (vell.y > -0.1 && vell.y < 0.1) vell.y = 0;
  else vell.y *= CoeffFriction;
}

Really thanks for your answer. Yes i know for my border. The game is not finish.
When he was finish i post the code

sorry, i only take a short look
-a- you use too may arrays what complicates the code,
pls make ONE array
[0] is the white ball
[1] … [7] red
[8] … [14] yellow
[15] black
you can store the color in the class or just make for the color a if else

you can also put the first position to an array
so the first_placing_ball() can be a one-line command

also might be good to make one array for the holes.

-b- what is confusing
in
ball_detection()
you calculate a distance between all balls
( loop over i and j ?? looks like check each collision twice? )
using dist()
then you call
calculate_collision()
and inside you calculate distance again??
but use d = sqrt(sq(dx)+sq(dy))

add one time compare with ballSize and one time with 2* ballSize

while you use PVector could use
https://processing.org/reference/PVector_dist_.html

for the mag calc
https://processing.org/reference/PVector_mag_.html

the rest defines a x y position for the 2 balls after collision,
that should be a new direction and speed, but not position???
