Godot: How to run export to GLTF tool from script in game? - godot

Hello everyone I am creating a game on the Godot engine.
I need to generate a mesh from scene and save it to a file when the game is running.
I'm trying to use Godot Project/Tools/Export_GLTF in the script, but I don't find any possibilities for this.
Can anyone help me with this? Is it possible to use the built-in Godot tool in the script or do I need to write objmaker myself?

I'm trying to use Godot Project/Tools/Export_GLTF in the script, but I don't find any possibilities for this.
You cannot access that function from scripting. However, right now in Godot 3.4+ you can do this in a tool script:
var gltf := PackedSceneGLTF.new()
var err := gltf.export_gltf(self, "res://scene.gltf")
if err != OK:
print("error: " + str(err))
I need to generate a mesh from scene and save it to a file when the game is running.
I reiterate that you can do what I said above from the editor (in a tool script), not from the game. This is because the necessary GLTF related classes are excluded from the game builds of Godot (i.e. the export templates). So you would need to make a custom build of Godot to have this functionality in your game.

How to export blender osm to godot so I can use it as a car track?

I'm new to Godot and Blender. I have an assignment where I have to create some kind of driving simulator. I already create the track using blender OSM and export it as .glb and it looks like this:
When I tried to export it to Godot, it turns like it is drowned and the materials are off:
Any advice on how should I do it so I can use the track that I already made on my project at godot? Hope I explain everything well.

Pixi js: recognize objects on image

I want to create carcassonne-like game using pixi js. Each tile is a separate image and I need to recognize some objects on this image like roads, towns etc. Is it possible to use pixi for this purpose? If yes what approach I need to use? I googled it but can't find anything useful.
First of all: Of course you can use pixi.js for this purpose. But you should keep in mind that pixi is not a gaming engine. It's just a renderer, so you have to do a lot of the calculations like collisions and positioning for your game by yourself.
A possible approach (I'm sure there are tons of other ways to do it):
You should preload all of you images
Create a Container: var myContainer = new PIXI.Container();
Create textures for your images: var texture = new PIXI.Texture(yourImageStoringObject)
Add the textures to you container: myContainer.addChild(texture);
Create an additional container holding your hit areas (roads, towns
etc) and add this container to the main container again.
Create some pixi geometrics like rectangles (new
PIXI.Rectangle(x,y,w,h)) or circles representing you hit areas and
add them to your hit-area-container
Right now my answer is kind of a abstract approach. I'm just guessing what could help you to start your project. Try to figure out some basics and ask for help again. If you could provide some chunks of code it's a lot easier to help out! :)

Vaadin - SVG Generator, any alternative?

I have been working with Vaadin charts during this week and I found a problem that I cannot solve. I need to send several charts to a PDF generation (using iTextpdf) and I could do it using SVGGenerator. The main problem is I cannot use this solution because the final laptop doesn't allow any installation, and Phantomjs is required for SVG Generator (no add-on can be installed neither). I tried to find a different solution to convert the chart content into file or buffer that I can manage, but I think I have been reading so much posts and I am not able to distinguish the solution.
So, I will try to clarify basic questions first:
a) Is it possible to manage SVG Generator without any installation in the laptop?
b) If not, is there a different way to convert a chart into an object which class could be managed to insert it into a PDF?
I can assure you I tried to read all documentation in this forum and official Vaadin forum related to this topic but I couldn't find any solution. I don't want to seem lazy, I only want to avoid spending more time and clarify the maining pre-conditions to solve this issue.
thanks in advance for your time and help.
Kind regards,
David.
You can take a screenshot of your chart and append it to pdf:
Screenshot screenshot = new Screenshot();
screenshot.setTargetComponent(myTargetComponent);
myChartLayout.addComponent(screenshot);
//when complete
screenshot.addScreenshotListener(new ScreenshotListener() {
public void screenshotComplete(ScreenshotImage image) {
//do something
}
});
//take screenshot
screenshot.takeScreenshot();
You will not be able to render a Vaadin Chart without a web browser engine of some kind. That's what PhantomJS provides. If you have a full-blown web browser at your disposal, though, you can grab the SVG markup manually from there; it's just a bit more difficult to automate. This works in Chrome:
Open your Charts app in the browser
Open the JavaScript console (Ctrl/Cmd + Shift + J)
Type something like this: copy(document.getElementsByTagName('svg')[0].outerHTML)
Paste the contents of your clipboard to a new text file and save it as an SVG.
You don't need to install phantomjs, just bundle its binary along with your web application (Reference). I did the same thing with my Amazon AWS deployment and it works just fine.

Create a map with clickable provinces/states using SVG, HTML/CSS, ImageMap

I am trying to create an interactive map where users can click on different provinces in the map to get info specific to that province.
Example:
archived: http://www.todospelaeducacao.org.br/
archived: http://code.google.com/p/svg2imap/
So far I've only found solutions that have limited functionality. I've only really searched for this using an SVG file, but I would be open to other file types if it is possible.
If anyone knows of a fully functioning way to do this (jQuery plug-in, PHP script, vector images) or a tutorial on how to do it manually please do share.
jQuery plugin for decorating image maps (highlights, select areas, tooltips):
http://www.outsharked.com/imagemapster/
Disclosure: I wrote it.
Sounds like you want a simple imagemap, I'd recommend to not make it more complex than it needs to be. Here's an article on how to improve imagemaps with svg. It's very easy to do clickable regions in svg itself, just add some <a> elements around the shapes you want to have clickable.
A couple of options if you need something more advanced:
http://jqvmap.com/
http://jvectormap.com/
http://polymaps.org/
I think it's better to divide my answer to 2 parts:
A-Create everything from scratch (using SVG, JavaScript, and HTML5):
Create a new HTML5 page
Create a new SVG file, each clickable area (province) should be a separate SVG Polygon in your SVG file,
(I'm using Adobe Illustrator for creating SVG files but you can find many alternative software products too, for example Inkscape)
Add mouseover and click events to your polygons one by one
<polygon points="200,10 250,190 160,210" style="fill:lime;stroke:purple;stroke-width:1"
onmouseover="mouseOverHandler(evt)"
onclick="clickHandler(evt)" />
Add a handler for each event in your JavaScript code and add your desired code to the handler
function mouseOverHandler(evt) {};
function clickHandler(evt) {};
Add the SVG file to your HTML page (I prefer inline SVG but you can use linked SVG file too)
Upload the files to your server
B-Use a software like FLDraw Interactive Image Creator (only if you have a map image and want to make it interactive):
Create an empty project and choose your map image as your base image when creating the new project
Add a Polygon element (from the Shape menu) for each province
For each polygon double click it to open the Properties window where you can choose an event type for mouse-over and click,
also change the shape opacity to 0 to make it invisible
Save your project and Publish it to HTML5, FLDraw will create a new folder that contains all of the required files for your project that you can upload to your server.
Option (A) is very good if you are programmer or you have someone to create the required code and SVG file for you,
Option (B) is good if you don't want to hire someone or spend your own time for creating everything from scratch
You have some other options too, for example using HTML5 Canvas instead of SVG, but it's not very easy to create a Zoomable map using HTML5 Canvas,
maybe there are some other ways too that I'm not aware of.
Just in case anyone will search for it - I used it on several sites, always the customization and RD possibilities were a perfect fit for what I needed. Simple and it is free to use:
Clickable CSS Maps
One note for more scripts on a site: I had some annoying problems with getting to work a map (that worked as a graphic menu) in Drupal 7. There where many other script used, and after handling them, I got stuck with the map - it still didn't work, although the jquery.cssmap.js, CSS (both local) and the script in the where in the right place. Firebug showed me an error and I suddenly eureka - a simple oversight, I left the script code as it was in the example and there was a conflict. Just change the front function "$" to "jQuery" (or other handler) and it works perfect. :]
Here's what I ment (of course you can put it before instead of the ):
<script type="text/javascript">
jQuery(function($){
$('#map-country').cssMap({'size' : 810});
});
</script>
Go to SVG to Script
with your SVG the default output is the map in SVG
Code which adds events is also added but is easily identified and can be altered as required.
I have been using makeaclickablemap for my province maps for some time now and it turned out to be a really good fit.
I had the same requirements and finally this Map converter worked for me. It is the best plugin for any map generation.
Here is another image map plugin I wrote to enhance image maps: https://github.com/gestixi/pictarea
It makes it easy to highlight all the area and let you specify different styles depending on the state of the zone: normal, hover, active, disable.
You can also specify how many zones can be selected at the same time.
The following code may help you:
$("#svgEuropa [id='stallwanger.it.dev_shape_DEU']").on("click",function(){
alert($(this).attr("id"));
});
Source
You have quite a few options for this:
1 - If you can find an SVG file for the map you want, you can use something like RaphaelJS or SnapSVG to add click listeners for your states/regions, this solution is the most customizable...
2 - You can use dedicated tools such as clickablemapbuilder (free) or makeaclickablemap (i think free also).

<script type="text/javascript">
jQuery(function($){
$('#map-country').cssMap({'size' : 810});
});

Displaying Maya Mesh XML in browser

I have a Mesh file (XML format) created in Maya.
I would like to display it in the browser with some additional options for the user, like rotating an zooming in and out.
What should be the best and easy method to do so?
(SilverLight, HTML5/JS/Canvas, Flesh)
I would really like to try HTML5/Canvas - is there any libraries that know how to do it?
Thanks.

You can visit this site learningwebgl
There are a lot of lessons and demos. On the right side there is a list of frameworks.
But you need browser support for webgl...
If you are willing to export your file in Collada/DAE format (which is basically XML), there are some online WebGL framework demos that show that a DAE file can be displayed the way you wish.
The frameworks that I've seen this for are GLGE and SpiderGL.
(WebGL is the 3D version of HTML5/Canvas.)
you can export your maya scene with http://www.inka3d.com and then manipulate it with javascript
