Panda 2 Tips & tricks

I will be posting here some tips and tricks for Panda 2.

Here is first. If you want to create class that doesn't show up in the sidebar you can do it like this:

game.Player = game.Class.extend({
    init: function() {
        
    }
});

If you need to check what version of plugin are you using, type this into JavaScript console:

game.modules['plugin.three'].version

Example:

Want to set your game window to specific size? This is great for testing your game on different resolutions and for taking screenshots.

First detach the game window to it's own window by pressing the detach button.

Then click the detach button again while pressing Shift-key down. Popup window will appear, type the size you want into the window, for example "320x480":

This will change the game window size so that the game area itself is exactly the resolution you entered (the red area):

Create slowmotion effect easily by changing the speed of the main game timer. Keep in mind that this affects everything in the game (tweens, timers etc).

// 50% slowdown for 1 second

game.Timer.speed = 0.5; // This will slowdown everything to 50%

game.Timer.add(500, function() { // So this will take 1 second to complete
    game.Timer.speed = 1; // Back to normal speed
});

If you have a repeating tween, but want to start it from a random time, just use this code after you have created your tween:

tween.currentTime = tween.duration.random();

For example, if a have a button that i want to swing from side to side using tween, but don't want it to always start from same position:

var button = new game.Sprite('button.png');
button.rotation = -0.1;

var tween = game.Tween.add(button, {
    rotation: 0.1
}, 1000, {
    repeat: Infinity,
    yoyo: true,
    easing: 'Quadratic.InOut'
}).start();

tween.currentTime = tween.duration.random();

Play sound effect with slightly random pitch, so it doesn't sound exactly same every time:

var sound = new game.Sound('jump.m4a');
sound.rate = Math.random(0.9, 1.1);
sound.play();

By default, all audio is stopped when you change scene. Want to disable that? Add this to your config:

audio: {
    stopOnSceneChange: false
}

Want to exclude some core modules from build (if you don't need them) to make the size even smaller? Specify those modules in your config like this:

game.config = {
    ignoreModules: ['engine.pool', 'engine.storage']
};

Modules that you can ignore are:

engine.audio
engine.particle
engine.physics
engine.pool
engine.storage
engine.tween

How to display icons in your projects list instead of screenshot?

Just place icon.png file in the root of your project. Optimal size is 120x120.
