I want make my label of Scene2D larger. I have scaled and set width and height to 200 and higher and it stays the same size.
Help? thanks.
So you want a bigger font size?
You can do that by calling lbl.font.setScale(yourFontSize);.
Sorry for my bad english, it is my code:
super(view, batch);
LabelStyle lbl = new LabelStyle();
lbl.font = new BitmapFont();
lbl.fontColor = Color.WHITE;
score = new Label("Score: ", lbl);
score.setPosition(getCamera().viewportWidth / 2, getCamera().viewportHeight - 150);
score.setSize(100, 100);
score.setSize(200, 200);
score.setScale(1.5f);
score.act(Gdx.graphics.getDeltaTime()); // update now

So this one is a little hard to explain. I have a custom Text class that automatically resizes and sets the width of the text when you change its value. I then take that Text and draw it on a Bitmap to scale it up to make the text look pixelated.
I have a property called maxWidth that allows you to restrict the width of the text if you want it to maintain a certain width. By default the maxWidth is the width of the text's parent so that it doesn't get cut off or expand the parent's boundaries unexpectedly.
So unfortunately when I draw the text it sometimes gets cut off on the right side. Now I've checked all the values and the width and textWidth are showing up as within their maxWidth values, but when I take a look myself through screenshots I see the text is actually about 3 pixels wider than it should be.
Here's an image to better explain what I mean:
I turned on borders so you can easily see what I mean. The word "and" on the first line gets drawn outside its border. Here is the line of code that handles resizing text when you change its bounds.
override protected function checkResize(value:String):void {
var bufferWidth:uint = Math.floor(Number(defaultTextFormat.size) / bufferDivisor) + bufferMin;
var maxWidth:Number = this.maxWidth;
x = y = 0;
if (parent is Stage) {
var stageParent:Stage = Stage(parent);
super.width = stageParent.stageWidth;
super.height = stageParent.stageHeight;
if (maxWidth == 0) maxWidth = stageParent.stageWidth;
}
else {
super.width = parent.width;
super.height = parent.height;
if (maxWidth == 0) maxWidth = parent.width;
}
maxWidth = maxWidth / scale;
text = value;
if (textWidth + bufferWidth <= maxWidth) super.width = textWidth + bufferWidth;
else super.width = maxWidth;
super.height = textHeight + 4;
if (textSnapshot) updateSnapshot();
if (alignRelation) Align.alignTo(textSprite, alignRelation, alignDirection, alignXOffset, alignYOffest);
}
And for this text specifically the width value states it's 512, which is correct since that's the maxWidth. However if you notice the top line in the text, it goes beyond the 512 width border, it actually goes all the way to 515 even though it says its width is 512. Even more bizarre is the textWidth states it's 510.4 even though the first line goes well beyond that amount. I just want to know if I'm doing anything wrong or if there's a way to get a true textWidth value.
This seems to be related to embedding fonts, at least it was when I had the same problem. A workaround is to set the right margin of the text field, like so
var tf:TextFormat = new TextFormat();
tf.rightMargin = 10; // or whatever fixes your problem, e.g. relate it to font size
textField.setTextFormat(tf);
When I give the canvas element width: 100% it gets pixelated even at a really small size. I tried giving the canvas itself a big size but it changes nothing. How can I keep the text sharp?

Setting Canvas Tag's size though css is not the best way do it.
Cause it enlarges the canvas's original size by a ratio of the width and height values you specify in css.
Below is how to set canvas width to the size of the window.
var can = document.getElementById('overlay'),
ctx = can.getContext("2d");
//innerWidth and innerHeight values of the window are the screen size.
can.width = window.innerWidth;
can.height = window.innerHeight;
ctx.font = "Bold 36px 'Helvetica'";
ctx.fillStyle = "black";
ctx.fillRect(0,0,1000,1000);
ctx.globalCompositeOperation = 'destination-out';
ctx.fillText("Some Text", 25, 50);
We can create a rectangle at (0,0) and height and width of 40 with mySprite.graphics.drawRect(0,0,40,40);. However, suppose it is necessary to create a rectangle that fills exactly half the screen (this is for mobile devices, so screen size will vary). How can we accomplish this?
You first need to get the size of the screen, you can use this :
var w = stage.stageWidth;
var h = stage.stageHeight;
Then you can simply draw your rect using theses variables
mySprite.graphics.drawRect(0, 0, w / 2, h / 2);
How do you find out the size of the system chrome so that I can specify the window size to achieve the stage size I want?
If my main window is set at 800 x 600 (stage), and I create a second window as below, it will be smaller.
public function Main():void
{
var windowOptions:NativeWindowInitOptions = new NativeWindowInitOptions();
windowOptions.systemChrome = NativeWindowSystemChrome.STANDARD;
windowOptions.type = NativeWindowType.NORMAL;
var newWindow:NativeWindow = new NativeWindow( windowOptions );
newWindow.width = 800;
newWindow.height = 600;
newWindow.stage.scaleMode = StageScaleMode.NO_SCALE;
newWindow.stage.align = StageAlign.TOP_LEFT;
newWindow.activate();
}
I assume you increase both newWindow.width = 800; and newWindow.height = 600;to account for the chrome, but how do you find this value?
you can calculate the size of the chrome by substracting the windows size (that include the chrome) with the inner size (that exclude the chrome).
From the width help of NativeWindows :
The dimensions reported for a native window include any system window
chrome that is displayed. The width of the usable display area inside
a window is available from the Stage.stageWidth property.
So the inner size can be obtained with stage object ( stage.stageWidth and stage.stageHeight: )
hence :
var chromeWidth=newWindow.width-newWindow.stage.stageWidth;
var chromeHeight=newWindow.height-newWindow.stage.stageHeight;
When creating ActionScript projects with NO_SCALE the stage.stageHeight and stage.stageWidth cannot be used to calculate chrome in the main application window as they do not resize to conform to the inner width. You must reference the main window stage.
To find the main windows inner stage height and width you can use the stage.nativeWindow.stage references stageHeight and stageWidth properties which gives inner width.
e.g. for a 1280x720 desired inner size:
// width stage.nativeWindow.width = 1280 + (stage.nativeWindow.width -
stage.nativeWindow.stage.stageWidth);
// height stage.nativeWindow.height = 720 + (stage.nativeWindow.height
- stage.nativeWindow.stage.stageHeight);
For reference, as I feel the other answers aren't clear enough. To set a new window to the desired dimensions:
// first set the desired window dimensions to set the (smaller) stage dimensions:
newWindow.width = 1024;
newWindow.height = 768;
// then reset the window dimensions and add chrome dimensions:
newWindow.width = 1024 + (1024 - newWindow.stage.stageWidth);
newWindow.height = 768 + (768 - newWindow.stage.stageHeight);
Both of sprite.width and sprite.scaleX can be used for scale a sprite. Is possible sprite.scaleX depends on screen size?
When you change the width property, the scaleX property changes accordingly
var rect:Shape = new Shape();
rect.graphics.beginFill(0xFF0000);
rect.graphics.drawRect(0, 0, 100, 100);
trace(rect.scaleX) // 1;
rect.width = 200;
trace(rect.scaleX) // 2;
official documentation
You should read the official documentation about scaleX and width.
By default, scaleX=1 which means there is no rescaling of the sprite, it does not depend on anything, you may set it freely.
