Phaser 2.0 enableBody moves sprites

[tarr11]

Hi -

 

I'm moving some code over to 2.0, and I've noticed that when I turn on enableBody=true for a group, it moves the sprites down slightly.  Is this expected?

 

Here's a sample of this code:

You can repro the behavior by commenting out line 57 in game.js

Depending on which system you use it's probably because they've had their anchors changed to 0.5.

It seems to happen regardless of using P2 or Arcade.

 

I'm creating these sprites using createFromObjects, maybe it's related to that.

Yes almost certainly, I'm pretty sure object coordinates in Tiled JSON related to their bottom-left point. Should be easy enough to determine.

[tarr11]

I can verify this is happening by manually placing a new sprite at the same coordinates. they don't match against Tiled.

This wasn't happening in 1.6, so Im not sure if this is a bug or feature :-)

Should I reset my sprite locations to a different offset somehow?

Looking at the createFromObjects code I was remembering rightly, Tiled does assume a bottom-left placement and I appear to have resolved that by setting the object anchor to x: 0, y: 1, which now conflicts with the Body setting using the anchor as an offset.

 

You can verify this by checking the anchor of mushrooms.children[0] for example.

 

What needs to happen is when createFromObjects runs, it looks-up the tile height and then adjusts the y coordinate by that amount. I'll add it to the list!

Ok in the dev branch I've updated the TilemapParser so it now adjusts the y coordinates by the tile height, and Tilemap no longer sets the anchor to 0,1 either.
