# Holding the same angle

Hi guys,
A few days ago i posted a question about a bubbleshooter game i wanted to make. I’ve now managed to make the bullet move towards my mouse position, but the angle keeps changing if i move the mouse. I want the angle to be fixed after I press the mouse button.

Hopefully you could help me!

<Ball b;
ArrayListbullets;
void setup(){
size(840,840);
b = new Ball();
bullets = new ArrayList();
}

void draw(){
background(0);
b.display();

//Bullets
Bullet bullet = bullets.get(0);
bullet.display();
bullet.move();

}

class Ball{
float x= width/2;
float y=height;
Ball(){
}

void display(){
fill(255);
ellipse(x,y,50,50);
}

class Bullet{
float x =width/2;
float y=height;
boolean doOnce =false;
Bullet(){

}

void display(){
fill(255);
ellipse(x,y,12.5,12.5);
}
void move(){
float distancex = (mouseX-b.x);
float distancey = abs(mouseY-height);
float angle = atan((distancey/distancex));
if (mousePressed == true){
doOnce = true;
}
if (doOnce == true){
if (angle>0){
x+= 3cos(angle);
y-= 3
sin(angle);
}
if (angle<0){
x-=3cos(angle);
y-=3
-sin(angle);
}}}
}

In Theory upon firing store the angle in the class and use it in move

Hence change move()
