When working with Phaser3, this worked:
map.createFromObjects('Layer_Objects', 'sprite', { key: 'item' })
'Layer_Objects' is the name of layer in Tiled. 'sprite' is the image name that will replace the itens created in the layer. 'item' is the name of points created with Tiled. I've tried many other options, but none of them worked, some of them asks for a GID, but Tiled is not generating this property. This project is being made with Phaser 2 CE, latest version.
