try using: pj.animations.add('up',[0,1,2,3,4,5], 10, true, false); ran into this myself, was because i was using an array in the textureAtlas json instead of a hash.
Messing around with textureAtlas in the 1.00JS branch - seems one of the animation parser methods might be inconsistent (with one broken). src/animation/Parser.js:102 v.s. src/animation/Parser.js:165 one's a for(; loop and the others for..in leaves src/animation/Parser.js:115 trying to use `frames[key]` instead of `frames` Hope that makes sense and sorry if I've got it wrong! (Phaser's aweome btw ^^)
