Create an Entity

To create an Entity, we create a JSON file and add it to the ‘entities’ section of the config.json file with the id that we want to refer to it by in the code as shown below:

"entities": [
    {"id": "dirt",            "src": "entities/dirt.json"},
    {"id": "gem",             "src": "entities/gem.json"},
]

Once we have this in place we can start editing the entity JSON file. Here we add the components that we want to make up the entity. Here is an example of an entity JSON file with two component definitions:

{
	"id": "pickaxe",
	"components":
	[
		{
			"type": "collision-basic", 
		 	"shape": {
				"offset": [0,-140],
				"type": "rectangle",
			   	"points": [ [-100,-140], [100,140] ]
			},
			"collisionType": "pickaxe"
		},{
			"type": "destroy-me",
			"message": "prepare-for-collision",
			"delay": 50
		}
	]
}

The types are the ids of the components from the game/config.json file. The other fields are passed in as the definition into the constructor of the components.
