Use Items

Learn how to use items that are in your game.

1. Using the item

After creating your item and attaching it to the player we can now use the item by using the useItem function in the room.js file. For this example we will use their item when they click which you can review in the events tutorial.

onMessage(client, data) {
	const  player = g.getACharacter('players', client.sessionId);
	const  actions = {
		click: () =>  g.useItem(player),
	}
	g.handleActions(actions, data);
}

This example will use the players item that is selected when they clicked.

2. Switching Items

In order to switch the item that the player is holding you will need to use the switchItem function in the room.js file. For this example we will switch items when space is pressed again review events.

onMessage(client, data) {
	const  player = g.getACharacter('players', client.sessionId);
	const  actions = {
		click: () =>  g.useItem(player),
		space: () => g.switchItem(player),
	}
	g.handleActions(actions, data);
}

This would switch the item to the next available item when space is pressed.

3. Using Actions

After doing all of this it should work fine, but if you want to use the built in functions for items of swingItem, throwItem, or placeItem there is a couple more steps.

First since we will be moving them we need to make sure they have the same ability to move as the characters so we will add them as characters in the game.js file inside of the init method

init() {
	g.addCharacters('pickaxe');
}

Then we need to make sure we are getting the items every time they are changed or moved in the create method.

create() {
	g.getCharacters('pickaxe');
}

Now inside of the createNewItem function you made in the room.js file you will be able to throw the item, place the item, or swing the item Ex:

onInit() {
	g.createNewItem('pickaxe', 'pickaxe.png', (player, data, actions) => {
		actions.swingItem();
		*or*
		actions.throwItem(data.x, data.y);
		*or*
		actions.placeItem();
	})
}

Lastly to make sure the items move when you use throwItem you would have to make sure and handle the animation with the handleAnimations function inside of the room.js file inside of the onUpdate method.

onUpdate() {
	g.handleAnimations('pickaxe');
}
