Forums » Help » problem with this.currentAnim.flip.x

Hi All,

I am stucked with this.currentAnim.flip.x. very weird!

this.currentAnim.flip.x=this.flip; is working fine in init() but not in update();

when added in update(), it throws an error saying TypeError: 'undefined' is not an object (evaluating 'this.currentAnim.filp.x=this.flip')

no clue why this is happening...

what I am trying to do with this entity is to get the entity loop in a range, change vel.x and flip.x when hitting the boundary of the range.

ig.module(
    'game.entities.enemyHBDive'
)
.requires(
    'impact.entity',
    'game.entities.enemy'
)

.defines(function(){
    EntityEnemyHBDive=EntityEnemy.extend({
        
           animSheet: new ig.AnimationSheet( 'media/hamburglerDive.png', 135, 59 ),
           
           name:'HBDive',
           size: {x:135, y:59},

It&039;s #.flip, not .filp :)

that is embarrassing! You really have good eyes Dominic. Many thanks! It bothered me for days. It is working very well now
