Forums » Help » Set var to be used in init of entities

Where and how do I do this? I can't put it in game because that doesn't exist yet, so I thought about making a simple controller entity that everything extends from but I'm getting undefined errors. Is there a simple way to run logic using the impact libraries that will be accessible when setting properties of entities or in the init function of entities?

made a controller entity that everything extends from:

ig.module(
	'game.entities.Controller'
)
.requires(
	'impact.entity'
)
.defines(function () {
    EntityController = ig.Entity.extend({});
})
var globalVar;

main loads this first and because everything extends from it the globalVar is accessible in all other entities where ever I need it. Not the best solution I'm sure but it works well.

Can you explain a bit more? I didn't understand what you are trying to do.

have a variable that can be accessed in the init functions of all entities that uses core elements (ig.ua or ig.Entity or anything already loaded).

Game properties are available to entities during init.

// lib/game/main.js
MyGame = ig.Game.extend({
    info: 'This is available to all entities.'
    ...
});

// lib/game/entities/example.js
EntityExample = ig.Entity.extend({
    init: function(x, y, settings) {
        console.log(ig.game.info);
    },
    ...
});

@joncom that was not my experience. I thought the same thing but using your code (or my previous code) gives me an "ig.game is undefined" error.

I believe something has gone wrong, because your entities should be able to access the ig.game instance. Mind sharing your code (minus the impact library) so we can take a closer look?
