Keyboard input issue

neanderground

Hi I try to figure it out why I can't control my character with the keyboard but Im lost here the code its too long to share here if anybody could look at it would be much appreciated

Please describe the problem. What do you mean you cannot control your character? What are you trying to do?

I tried to share the code but I cant show it here properly because

here are the variables in the main tab

public float bellyXloc, bellyYloc;
public float bellyWidth, bellyHeight;
public float accelerationX,accelerationY;
public float decelerationX, decelerationY;
public PVector location, acceleration, deceleration;
public float max_speedx,max_speedy ;
public float gravity;
public color characterColor;
public Boolean   isLeft=false ,  isRight=false , isUp= false ;

constructor

 bellyXloc=width/2;
  bellyYloc=height/2; //-(1.6*bellyHeight);
  bellyWidth=width/20;
  bellyHeight= height*0.1;
  characterColor = color(152,223,234);
  location = new PVector(bellyXloc,bellyYloc);
  accelerationX=1.3;
  accelerationY=0;
  max_speedx = 5;
  max_speedy = 3;
  acceleration = new PVector(accelerationX,accelerationY);
  decerelationX = 0.75;
  decerelationY = 0.75;
  deceleration = new PVector(decelerationX, decelerationY);
  gravity = .3;


  a = new AlienCharacter(location,bellyWidth,bellyHeight, color(152,223,234),
                        acceleration, max_speedx, max_speedy, decerelation ,gravity);

in the class void update

void update() {
if ( isRight ) {
  location.add(acceleration);
  if ( acceleration.x > max_speedx ) {
    max_speedx = acceleration.x;
  }
}
else if ( isLeft ) {
  location.sub(acceleration);
  if ( acceleration.x < -max_speedx ) {
    max_speedx = acceleration.x;
  }
}
else { //neither right or left pressed, decelerate
  if ( acceleration.x > 0 ) {
    acceleration.x -= deceleration.x;
    if ( acceleration.x < 0 ) {
      acceleration.x = 0;
    }
  }
  else if ( acceleration.x < 0 ) {
    acceleration.x += deceleration.x;
    if ( acceleration.x > 0 ) {
      acceleration.x = 0;
    }
  }
  }

  if ( isUp ) {
  location.sub(acceleration);
    if ( acceleration.y-0.5 < -max_speedy ) {
    max_speedy = acceleration.y*deceleration.y;
  }
  }

and in the main tab

  void keyPressed() {
  switch(keyCode) {
  case RIGHT: isRight  = true; break;
  case LEFT: isLeft = true; break;
  case UP: isUp = true; break;
  }
  }
  void keyReleased() {
  switch(keyCode) {
  case RIGHT: isRight = false; break;
  case LEFT: isLeft = false; break;
  case UP: isUp = false; break;

  }
  }

The problem that character doesn't react to keyboard

First thing:
deceleration <--> decerelation are different :)

I "purposely" wrote so people can correct me, but It doesn't work with the rest so far
