I'm using Unity 3 to build my game. I have a basic GUI button that when clicked, I would like the user to be taken to a random level. There are 10 levels in my game. Below is a copy of the code I'm trying to implement.
function OnGUI()
{
// Make a background box
GUI.Box(Rect(10, 10, 100, 90), "Oracle");
if (GUI.Button(Rect(20, 40, 80, 20), 9)) ;
{
Application.LoadLevel(Random.Range(0, 9));
}
}
It's not happening. I've also tried:
function OnGUI()
{
// Make a background box
GUI.Box(Rect(10, 10, 100, 90), "Oracle");
if (GUI.Button(Rect(20, 40, 80, 20))) ;
{
Application.LoadLevel(Random.Range(0, Application.levelCount 9));
}
}
I've never used the Random.Range function before and somewhat confused at the proper format.
Also I have EZ GUI available and was wondering if I could enter the correct Random Range script into the 'script' dropdown or 'script with method' drop down work it, as I'd rather use a custom button. Any assistance would be greatly appreciated.
Here is the code that worked. I will be rebuilding and adding a few more levels I will try the straight from the Unity docs and see if the random scene loads from just the number of scenes in the build. Thanks DigitalD
static var levelCount : int;
function OnGUI () {
// Make a background box
GUI.Box (Rect (10,10,100,90), "ORACLE");
if (GUI.Button (Rect (20,40,80,20), "Genie")) {
Application.LoadLevel (Random.Range(0, Application.levelCount-5));
}
}
The example code from the Unity docs should work fine. "Application.LoadLevel(Random.Range(0, Application.levelCount))" will load a random scene. The level numbers are based on the order in your build settings. Is is possible you forgot to include them in the build? Just having 10 scenes isn't enough, they'll be stripped out if they're not included in the build.

We have a somewhat simple game written using CocosSharp. The game is within another Xamarin.Forms app. When the player clicks to play the game, we bring them to a splash screen. On iOS this screen displays immediately but on Android, the screen is just black for about 15 seconds. The music plays pretty much immediately on both platforms.
The following is called from the ViewCreated event of the CocosSharpView.
InitializeAudio();
var scene = new Scenes.SplashScene(GameView);
GameView.RunWithScene(scene);
The hang up seems to be when creating labels. The following take ~10 seconds to complete with 99% of it being in the constructor of the first label. We call our CreateText in the constructor.
private void CreateText()
{
var label = new CCLabel("Text 1", "BD_CARTOON_SHOUT.TTF", 80)
{
PositionX = layer.ContentSize.Width / 2.0f,
PositionY = layer.ContentSize.Height / 1.5f,
Color = CCColor3B.DarkGray
};
layer.AddChild(label);
label = new CCLabel("Text 2", "BD_CARTOON_SHOUT.TTF", 60)
{
PositionX = layer.ContentSize.Width / 2.0f,
PositionY = 50f,
Color = CCColor3B.DarkGray
};
layer.AddChild(label);
}
Keep in mind this only happens on Android.
Thanks in advance!
I had the same issue several weeks ago. The problem was CCLabel constructor
where it didn't know which type of font are you using and therefore trying all other types before finally trying the last one which is correct. You need to specify font type in CCLabel constructor like this:
var label = new CCLabel("Text 1", "BD_CARTOON_SHOUT.TTF", 80, CCLabelFormat.SystemFont);
Hope it helps.
Is there some kind of Chrome addon or something for phaser to allow me to find out the x and y coordinates of where I wish to place sprites?
Right now, it's a guessing game. I have to use a number, reload the browser and then go to the point in the game (which might now be the beginning) and see if it's OK. Otherwise, repeat the process.
Is there anything better? A visual debugger or something similar?
I have tried using the standard Google Chrome dev tools, but I can't get access to the sprites inside the HTML canvas or WebGL.
if you don't have any action in the onClick callback, you can use something like this:
var text;
Jumper.Game.prototype = {
create: function() {
this.game.input.onDown.add(this.onTap, this);
},
onTap: function(pointer){
text = "x:"+parseInt(pointer.x)+" y="+parseInt(pointer.y);
},
render:function(){
this.game.debug.text(text || '--', 2, 14, '#00ff00');
}
}
or you can changethis.game.input.onDown.add(this.onTap, this); with this.game.input.addMoveCallback(this.onTap, this) for "live" position.
I am new to game development but familiar with programming languages. I have started using Flixel and have a working Breakout game with score and lives.
I am just stuck on how I can create a new screen/game over screen if a player runs out of lives. I would like the process to be like following:
Check IF lives are equal to 0
Pause the game and display a new screen (probably transparent) that says 'Game Over'
When a user clicks or hits ENTER restart the level
Here is the function I currently have to update the lives:
private function loseLive(_ball:FlxObject, _bottomWall:FlxObject):void
{
// check for game over
if (lives_count == 0)
{
}
else
{
FlxG:lives_count -= 1;
lives.text = 'Lives: ' + lives_count.toString()
}
}
Here is my main game.as:
package
{
import org.flixel.*;
public class Game extends FlxGame
{
private const resolution:FlxPoint = new FlxPoint(640, 480);
private const zoom:uint = 2;
private const fps:uint = 60;
public function Game()
{
super(resolution.x / zoom, resolution.y / zoom, PlayState, zoom);
FlxG.flashFramerate = fps;
}
}
}
There are multiple ways to go about doing this...
You could use different FlxStates, like I described in the answer to your other post: Creating user UI using Flixel, although you'll have to get smart with passing the score or whatever around, or use a Registry-type setup
If you want it to actually work like you described above, with a transparent-overlay screen, you can try something like this (keep in mind, the exact details may differ for your project, I'm just trying to give you an idea):
First, make sure you have good logic for starting a level, lets say it's a function called StartLevel.
You'll want to define a flag - just a Boolean - that tracks whether or not the game is still going on or not: private var _isGameOver:Boolean; At the very end of StartLevel(), set this to false.
In your create() function for your PlayState, build a new FlxGroup which has all the things you want on your Game Over screen - some text, an image, and something that says "Press ENTER to Restart" (or whatever). Then set it to visible = false. The code for that might look something like:
grpGameOver = new FlxGroup();
grpGameOver.add(new FlxSprite(10,10).makeGraphic(FlxG.Width-20,FlxG.Height-20,0x66000000)); // just a semi-transparent black box to cover your game screen.
grpGameOver.add(new FlxText(...)); // whatever you want to add to the group...
grpGameOver.visible = false;
add(grpGameOver); // add the group to your State.
Depending on how your game is setup, you may also want to set the objects in your group's scrollFactor to 0 - if your game screen scrolls at all:
grpGameOver.setAll("scrollFactor", new FlxPoint(0,0));
In your update() function, you'll need to split it into 2 parts: one for when the game is over, and one for if the game is still going on:
if (_isGameOver)
{
if (FlxG.keys.justReleased("ENTER"))
{
grpGameOver.visible = false;
StartLevel();
}
}
else
{
... the rest of your game logic that you already have ...
}
super.update();
Keep in mind, if you have things that respond to user input anywhere else - like a player object or something, you might need to change their update() functions to check for that flag as well.
Then, the last thing you need to do is in your loseLive() logic:
if (lives_count == 0)
{
_isGameOver = true;
grpGameOver.visible = true;
}
else
...
That should do it!
I would highly recommend spending some time with different tutorials and sample projects to kind of get a better feel for Flixel in general. Photon Storm has some great material to play with (even though he's jumped over to HTML5 games)
I also want to note that if you get comfortable with the way Flixel handles updates, you can get really smart with your state's update() function and have it only call update on the grpGameOver objects, instead of having to change all your other objects updates individually. Pretty advanced stuff, but can be worth it to learn it.
I have written a small application that performs some long-running tasks. Instead of having the user to wait and seeing just a progress bar, I would like to display some (changing) information about the application.
For that purpose, I wrote the following code within the constructor of an extended Pane:
FadeTransition fadeOutTransition = new FadeTransition(Duration.millis(1000), this);
fadeOutTransition.setFromValue(0.8);
fadeOutTransition.setToValue(0.0);
Similarly the fadeInTransition. And further...
SequentialTransition seqTransition = new SequentialTransition (
new Transition() {
{ setInterpolator(Interpolator.DISCRETE);
setCycleDuration(Duration.seconds(1)); }
protected void interpolate(double frac) {
int nextElement = (int) ((explenations.size() - 1) * Math.random());
Explenation explenation = explenations.get(nextElement);
questionLabel.setText(explenation.getQuestion());
answerLabel.setText(explenation.getAnswer());
}
},
fadeInTransition,
new PauseTransition(Duration.seconds(15)),
fadeOutTransition
);
What I woud like is the text to fade in, stay there for ~15 seconds and then fade out again. Unfortunately, the animation flickers, moves faster and slower - and the PauseTransition never takes 15 seconds! What is wrong about the code? I'm using Java 7, and JavaFX 2.2 on Mac OS X.
The problem seems to be that I called the function
seqTransition.play();
multiple times. From there comes probably the flickering and the unequal waiting time.
When setting the scrollTop and scrollLeft parameters in Safari 6 simultaneously, only one of both gets executed, scrolling the page only over one axis. This happens both using native JavaScript, jQuery and the jquery.scrollTo plugin.
Example using jQuery's .animate():
$('body').animate({
'scrollLeft': 100,
'scrollTop': 100
}, {
'duration': 500,
'easing': 'swing'
});
I've set up a demo page here: http://nabble.nl/demo/safari6scrollto/
All examples work fine in all major browsers as expected, in Safari 6 only example no. 4, 6 and 7 work.
Somehow, when loading the demo page in an IFRAME (see bottom of demo page), everything works just fine.
Is this a bug in Safari? If so, how to work around this issue? If not, what is causing it and how can this be resolved?
Other related reports:
https://github.com/flesler/jquery.scrollTo/issues/9
http://forum.jquery.com/topic/scrolltop-scrollleft-not-working-in-safari-6
http://bugs.jquery.com/ticket/12588
I needed to get the jquery.scrollTo plugin working on OSX Mountain Lion, and since I couldn't find the specifics on what is causing this behaviour, I put together a rather ugly workaround. It uses window.scrollTo(x, y) in the step function of jQuery's .animate(), which gives no problems in Safari 6:
var left;
$(window).animate({
'pageXOffset': 100,
'pageYOffset': 100
}, {
duration: 500,
easing: 'swing',
step: function(now, fx) {
if (fx.prop == 'pageXOffset') {
left = now;
} else if (fx.prop == 'pageYOffset') {
window.scrollTo(left, now);
}
}
});
Please note that the step function is called for every animated property, for every element the animation is applied on (in our case just 1: window). Hence the intermediate variable to store the current X position in the animation.
It uses the pageXOffset and pageYOffset properties of the window object, so I don't know how suitable this workaround is for animating the scrollLeft and scrollTop properties of non-window objects.
Anyway, it works for scrolling the entire document, which was all I wanted, and does so very smooth in Safari 6, too!
