I am using Phaser 3 to develop a browser game in a canvas with WebGL. I set the width of the canvas text from a custom loaded font, but I cannot set it's style (e.g., italic, semibold).
Here is the code that I use to create text:
this.add.text(100, 600, 'Test Text', {
font: '50px Poppins'
})
this.add.text(100, 600, 'Test Text', {
font: '50px Poppins semibold'
})
Here is the output:
The second image is using the default font, not Poppins. It seems that as soon as I try to set italic or any other style it will fallback to the default font.
I tried to set it with the properties as well (no luck). Has anyone faced the same issue (styling custom fonts), and how to properly load the styled custom fonts?
Issue:
semibold is not a valid font-weight. so it will be considered as font.
Solution:
this.add.text(100, 600, 'Test Text', {
font: '600 50px Poppins' // 600 equivalent to Semi Bold
})
https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight
The problem was related to the async loading of the fonts from google. With webfontloader from google I can wait with the active event till they are ready.
import WebFont = require('webfontloader')
export class BootScene extends Phaser.Scene {
private ready: boolean = false
constructor() {
super({
key: 'BootScene'
})
}
async preload(): Promise < any > {
WebFont.load({
google: {
families: ['Poppins:600i,600,400', 'Inconsolata']
},
active: () => {
// This is required for asnyc loading
this.ready = true
}
})
}
// Launch game when all assets are loaded
update(): void {
if (this.load.isReady() && this.ready) {
this.scene.start('MainMenuScene')
}
}
}
I have a graph chart made using echarts. When I hover on the edges, it displays some behavior set on the emphasis option. there is any way i can have this behavior happening when I click one of the edges ?
Emphasis code :
emphasis: {
lineStyle: {
width: 5,
color: "#555555"
}
}
myChart.on('click', (params) => {
if (params.dataType === 'edge') {
/* you can check params to look for what you want to pick */
myChart.dispatchAction({
/* HighLight type */
type: 'focusNodeAdjacency',
/* OffLight type if you need */
// type: 'unfocusNodeAdjacency',
/* Positioning the series with seriesId/seriesIndex/seriesName */
seriesIndex: 0,
/* Positioning the node with dataIndex */
dataIndex: params.dataIndex
});
}
})
I want to give title to the graph image which we get when we save the graph as image in Echarts. Echarts does not have option for the same. So, is there any way that we can achieve our requirement.
Attaching a link for your reference from echarts. Which provide the option for saveAsImage
https://ecomfe.github.io/echarts-doc/public/en/option.html#toolbox.feature.saveAsImage
As attaching a link of echarts example which has save image icon on the right top corner
https://ecomfe.github.io/echarts-examples/public/editor.html?c=area-rainfall
I also want to position the hover tooltip which we get on hover of the save image icon. they have some default options. But, I have to increase the space more.
I really thank the guys who can come up with the solution for the above requirement.
By default, the name of the image is the chart title.
You can set the title by using:
option: {
title: {
text: 'myTitle'
}
}
To provide a custom name, you can use the saveAsImage.name function:
option: {
toolbox: {
feature: {
saveAsImage: {
name: 'myImageName'
}
}
}
}
Bonus: To increase the space between the icons, you can set toolbox.itemGap, and maybe get the result you want:
option: {
toolbox: {
itemGap: 20,
bottom: 20,
...
}
}
Or customize the icons itself through toolbox.iconStyle. For example, by setting a transparent border:
option: {
toolbox: {
iconStyle: {
borderWidth: 10,
borderColor: rgba(0, 0, 0, 0),
...
}
}
}
Toolbox documentation
option: {
toolbox: {
feature: {
saveAsImage: {
title: 'Save',
}
}
}
}

require([

that uses a newer version of dojo but the EXACT same code. I've added the external resource "claro.css" for the appropriate version of dojo that I'm using in the Frameworks setting, and the same LOAD TYPE in the JavaScript settings, but my fiddle is clearly missing styles since it is not rendering like the original: the dialog box and BorderContainer are missing borders, background colors, and essentially all styles.
This is even more important since the same thing is happening (styles not being applied) to a dialog dijit in an application that I'm working on.
What am I missing in my fiddle??
You are missing the claro body tag. Click on Settings icon on HTML and add this to the body tag.

I am building a map with multiple geojsons in Leaflet and it has worked well on a normal size computer screen. It doesn't however work on smaller screens or Apple products and so I am attemting to move my code over to Smap-responsive https://github.com/getsmap/smap-responsive .
I have added a geojson following the given example and styled it based upon attributes, it looks how I want it to and the pop ups work how I want them to. The problem comes when I try to add a second geojson. When I click points on the first layer it works as it should but when I turn off that layer and turn on the second layer the popups don’t work on the second layer. If I refresh the page and try the second layer first, those popups work but then they don’t work on the first layer. The error i get is:
“Uncaught TypeError: Cannot read property 'properties' of undefined”
Here is the code:

The error points to "feature.properties." in the function that sets the colors of the first layer I turn on and it comes when I click to get a pop up on the second layer I have turned on. I haven't had this problem when using Leaflet without smap-resonsive.
I have tried moving the function out to an external js. file, defining the functions with "var something =". I have tried calling the colors direct from an attribute also but all give the same error.
I am new to Leaflet and Javascript, any help appreciated!
The error was caused by bug which meant that only the uppermost layer was selectable. Described here:
https://github.com/getsmap/smap-responsive/issues/198
Thanks to Johan Lahti for a quick reposonse in solving the problem!
