A few more questions about Phaser

[toto88x]

Hello,

 

I almost finished my first Phaser game!  Below are my questions.

 

1) How can I change the volume of one sound in my game? And what about all sounds? Something like

- var hit = game.add.audio('hit');

- hit.volume = 0.5;

 

2) How can I change the font size of a text? Because changing fontSize: '32px' doesn't seems to work.

- game.add.text(w/2, h-35, 'this is a test', { fontSize: '18px', fill: '#fff', align: 'center' });

 

3) When I do a game.state.start('GameOver'), should I clean all my variables to free memory? If so, is there a function automatically called before switching states?

 

4) I know about tween().to(), but isn't there something like tween().by()? This would be super handy to move a character by 100px, instead of moving him to character.x + 100px.

 

Thanks! :-)

1) I haven't messed with volume on sounds yet, but both the Phaser.Sound and Phaser.SoundManager classes have a volume property.

 

2) See here for the available font properties:

http://www.goodboydigital.com/pixijs/docs/classes/Text.html

There is no fontSize property, you include that in the font property. eg: 18px Arial

 

3) Probably a good idea. A state object has it's create function called when switching to it, and if an existing state was there, the existing state has its shutdown function called.

 

4) Nope.

Thanks a lot! A few comments:

 

1) Yes I've seen that, but I don't know how to make it work :-/

 

2) Perfect, it works! But it seems the fonts are somewhat blurry. Is this normal? What I'm doing: game.add.text(w/2, h/2, 'blurry text', { font: "18px Arial", fill: '#fff' });

 

3) shutdown works perfectly!

 

4) Ok, maybe in v1.2 then ^^

The problem there is probably positioning... Try rounding the x/y values. I usually use Math.floor:

game.add.text(Math.floor(w/2), Math.floor(h/2), 'blurry text', { font: "18px Arial", fill: '#fff' });

You can do this:

tween(sprite).to( { x: '+100' });

It will recognise +100 is a string and add 100px to the sprites current x position when the tween starts. Minus values work the same too.

Super nice, thanks!

 

 

I still don't know how to change the volume of sounds in the game (either a specific sound, or for all of them). Can anyone help me on this?

Set the volume property on the sound? It's between 0 and 1 and you usually set it on the call to play the sound.

Hi all, I have also some questions about Phaser, dunno need to create a new topic for that or no, but will ask here:

 

1) first two parameters don't work in tilemapLayer function

x - X position of the new tilemapLayer.

y - Y position of the new tilemapLayer.

layer = game.add.tilemapLayer(0, 0, 800, 600, tileset, map, 0);

 

I use that example:

http://www.gametest.mobi/phaser/examples/sideview.html

 

write:

layer = game.add.tilemapLayer(50, 50, 800, 600, tileset, map, 0);

 

and I don't see any changes. I just want to move the tilemapLayer to x = 50; y = 50.

 

also

layer.x = 50;layer.y = 50;

don't work for me let me know please what need to do.

 

2) Rich said, "In 1.1.4 I've added the ability to render multiple layers to a single canvas, but that won't be ready until end of this month."

does anyone know is this available or not now? I mean of course dev-branch version of Phaser.

 

[rich]

I've been working on both of these things today actually. Keep an eye on the commit messages on the dev branch, it will be obvious when they're ready to test.

Thanks rich, I look forward to it!

about the 1st of my item - I found a temporary solution via group.

 

if you want to move your tilemapLayer - you can just place him into the group and move it.

var screen = game.add.group();layer = screen.add(game.add.tilemapLayer(0, 0, 800, 600, tileset, map, 0));screen.x = 50;screen.y = 50;
