Help - Using 's' key to stop a character on center position

mnoble

Hello Forum Team,

Can you help me understand the logic in a simple way to use the 's' key to load image 1 in a frozen in-place position and make the left and right direction images (images 2 and 3) temporarily disappear. (Here I already have the left and right images working with 'a' and 'd' keys.)

int x1 = width/2; //START CHARACTER IN MIDDLE
int t = 255;
int r = 0;
boolean on = false;


PImage img1;
PImage img2;
PImage img3;

void setup(){
    size(800,600);
    smooth();
    strokeWeight( 2 );
    img1 = loadImage ("Mint3.png"); //CENTER IMAGE CURRENTLY NOT LOADING AFTER MOVEMENT BEGINS
    img2 = loadImage ("mintright.png");
    img3 = loadImage ("mintleft.png");
}

void draw(){
    background( 255 );
    tint (255,t);
    image(img1, x1, 300, 250,200); 

println ("x1=",x1);

    if (keyPressed) {    

   //go right   
      if (key == 'd' || key == 'D') {

          t = 0;
          noTint ();
          image(img2, x1, 300, 250,200);
          x1 += 1;


     //go left  
      } else if (key == 'a' || key == 'A') {

          t = 0;
          noTint ();
          image(img3, x1, 300, 250,200);    
          x1 -= 1;

         }  


 }   // <--close keyPressed 


} // <-- close draw

Write it out in English first, then convert this to code.

// If a key is pressed,
// If it's the a key,
// move where the left image is and draw it.
// or if it's the d key,
// move where the right image is and draw it.
// or if it's the s key,
// just draw the middle image.

Hello TfGuy44!

Thanks for working with me!

Here's my revision based on your breakdown. Is there a simple way to make the states be continuous until the next key pressed?

int x1 = width/2; //START CHARACTER IN MIDDLE


PImage img1;
PImage img2;
PImage img3;

void setup(){
    size(800,600);
    smooth();
    strokeWeight( 2 );
    img1 = loadImage ("Mint3.png"); //CENTER IMAGE CURRENTLY NOT LOADING AFTER MOVEMENT BEGINS
    img2 = loadImage ("mintright.png");
    img3 = loadImage ("mintleft.png");
}

void draw(){
    background( 255 );
    println("x1=", x1);


    if (keyPressed) {    

   //go right   
      if (key == 'd' || key == 'D') {
          image(img2, x1, 300, 250,200);
          x1 += 1;
      } 



    //go left    
     if (key == 'a' || key == 'A') {
          image(img3, x1, 300, 250,200);    
          x1 -= 1;              
         }          



       //just draw middle image in place 
       if  (key == 's' || key == 'S') {
           image (img1, x1, 300, 250, 200);
         }

    } // <-- close keyPressedß 

} // <-- close draw

make a variable int state that indicates the current image (0,1,2)

if a state = 0

with b state = 1

etc.

in draw say outside if keypressed

     //go right   
          if (state== 0) {
              image(img2, x1, 300, 250,200);
              x1 += 1;
          } 



        //go left    
        else  if (state==1) {
              image(img3, x1, 300, 250,200);    
              x1 -= 1;              
             }          



           //just draw middle image in place 
        else   if  (state==2) {
               image (img1, x1, 300, 250, 200);
             }
