getting the json after .load.atlasJSONHash

[xdiepx]

When using ".load.atlasJSONHasht", it loads the Json file with the image with all the data in it. How would you get the width and height using the json instead of putting a size in yourself?

 

for example:

 

function preload() {
     game.load.atlasJSONHash('bot', 'assets/sprites/running_bot.png','assets/sprites/running_bot.json');
}

 

var bot = game.add.sprite(200, 200, 'bot');
