Sprite animation not looping

[benjamin dudok]

I'm probably overlooking something, but i can't get my sprite animations to loop in the script below. I got 2 animations, walking and standing. And i'm trying to switch between the two when i press a button. the switching works, but if i hold down the button, the walking animation doesn't loop. I used certain code snippets from the Telemachus example and the animator.js is from the sprite and animations tutorial.

// create player sprites and put them in a group

    var playerSheet = new animator.SpriteSheet('images/player.gif',  {width: 32, height: 44});

    var playerAnimation = new animator.AnimationSheet(playerSheet, {'idle': [0], 'walk': [1,12]}, 25);

    var playercharacter = new PlayerCharacter([50, 400], playerAnimation);

    playercharacter.moveDelta = [0, 0];

    playercharacter.moveSpeed = 10;

    playerAnimation.start('idle');

     

   

    var keysDown = {};

    function handleEvent(event) {

      if (event.type === gamejs.event.KEY_DOWN) {

         keysDown[event.key] = true;

      } else if (event.type === gamejs.event.KEY_UP) {

         keysDown[event.key] = false;

      };

      

      // left, right

      if (keysDown[gamejs.event.K_a]) {

         playercharacter.moveDelta[0] = -playercharacter.moveSpeed;

         playerAnimation.start('walk');

      } else if (keysDown[gamejs.event.K_d]) {

         playercharacter.moveDelta[0] = +playercharacter.moveSpeed;

         playerAnimation.start('walk');

      } else {

         playercharacter.moveDelta[0] = 0;

         playerAnimation.start('idle');

      }

      // up / down

      if (keysDown[gamejs.event.K_w]) {

         playercharacter.moveDelta[1] = -playercharacter.moveSpeed

         playerAnimation.start('walk');

      } else if (keysDown[gamejs.event.K_s]) {

         playercharacter.moveDelta[1] = +playercharacter.moveSpeed;

         playerAnimation.start('walk');

      }  else {

         playercharacter.moveDelta[1] = 0;

      }

   };

Hi Benjamin,
from the code it seem you keep (re-)starting the the animation the whole time while a key is down - this won't work; you'll have to keep track of whether the right animation is already running and only start it when needed.
