Check if atlas frame exists

[Croweley]

Is there a way to check if a frame exists within an atlas? Preferably before setting the frame name in a sprite.

[nkholski]

game.cache._images[atlasName].frameData._frameNames.hasOwnProperty(frameName)

 

Returns true or false. (atlasName = name of your atlas, frameName = frame you want to test.)

Avoid digging into _* and internals manually.

Using:

game.cache.getFrameByName('characters/player.png')

will return null if no frame of that name is found.

Very late reply, but I was looking for a solution to the same issue. I don't think nemoDreamer's anser would work, it seems to just look for an image, not texture atlas frame.

I'd also avoid using underscore as in the first reply, but you can do something with Phaser only methods like this:

function hasFrameName ( { atlasName, frameName } ) {
  return this.state.cache.getFrameData( atlasName ).checkFrameName( frameName )
}
