  • Hello,

    I've spent 2 days trying to figure this out on my own, but I'm starting to think there's a bug in Construct 3's XML plugin, or I'm missing something obscure.

    I'm trying to use Construct 3 to create a prototype for a web app I want to build, but I can't seem to get some basic functionality out of the XML plugin that I absolutely need to get this prototype working. I included a project file for debugging purposes, if you think you know what's going on, I would really appreciate some help.

    https://drive.google.com/file/d/1IjF4vBzXz3fAqpPodW5qC23PJNQRGFPt/view?usp=sharing

    In the project, the user selects an SVG file from their PC and uploads it. For the purpose of debugging, please use 'SVG to import.svg' included in the project files. Just download it and select it from the FileChooser. Once loaded, the SVG object sets its image to the loaded file, AJAX requests the string value of the data and saves it to local storage. A text object is set up to display the values being extracted, easily showing that the correct data is being extracted and saved. Then the user selects to load the data into the XML object from either AJAX.LastData, or LocalStorage.ItemValue.

    Either way, the string value should be the same, but this is there to demonstrate that the issue isn't with AJAX or LocalStorage.

    Then the user runs one of two XPath expressions to extract a particular value from the SVG file. Both XPath expressions work correctly when used with this website:

    https://www.freeformatter.com/xpath-tester.html#before-output

    string(//svg/rect[1]/@width) and number(//svg/rect[1]/@width) used with the 'SVG to import.svg' file both result in the value '188', so the expression is correctly working.

    The data that the XPath expression is supposed to extract is the 'width' attribute's value for the first 'rect' node. It's an arbitrary request and is just being used for the purpose of demonstrating the problem I'm having, however, the extracted value should be '188'. Instead, the XPath result is either "" or 0.

    I've tried several variations of the XPath expression to try and get it to work, but the only differing values I ever got were 'nan' or 'null'.

    I tried a lot to get this to work or figure out why it isn't working. I looked in the manual, forums, and education resources for learning how to use XPath expressions. This is my first time messing with XML, and I'm only doing it because .svg files are formatted like XML files, but I did my due diligence to try and figure it out before filling the forums with duplicate questions. I'm linking the other threads I found below, but they really didn't help me much.

  • Your solution in the other thread worked perfectly, and it was easy to implement! Thank you very much. I'm developing an FPS template for anyone to use, and this was a major road block. I made sure to credit you in the project files as well!

    If you're interested in checking out the template, here is the download link!

    Hard to say what you’re trying to calculate with the angles and how.

    If you are just turning you could just set the bullets angle to the cameras angle.

    If you look up and down too you can use spherical coordinates to get the orientation from two angles. But your math doesn’t look like that.

    Here’s a way to just shoot in the direction the camera is facing. Maybe something like that is what you’re after?

  • Hello all, I have managed to hack together a pretty decent 3D FPS template, but I can't seem to get my 3D bullets to match the angle the camera shoots at. Can anyone spot what is wrong with them? If you're good at geometry, it may help a lot! Thank you for any assistance!

  • After further investigating, it seems that the requests are simply blocking .json and certain other file extentions from being requested. .txt files work perfectly fine with AJAX. I guess if I hosted my own website it might work with .json files, but it may actually be a security feature in browsers to protect users, rather than the website itself, but I'm not sure about that.

    Basically, don't use AJAX to request .json if you plan on hosting your game as HTML on a site you don't run. Use .txt instead, if you can.

  • The HTTP 403 is an HTTP status code meaning access to the requested resource is forbidden. The server understood the request, but will not fulfill it.

    I looked it up after that last quote. I don't know how to get around that. I'm just trying to make a simple io game that pulls a giant list of names to use for bots. Does anyone know another way I can easily write up a list of bot names in an array without manually setting it with events?

  • check that all the files from the export are getting uploaded to the server. check the console (f12) to see if there are any errors - probably 404 (file not found)

    I also rewrote some of the code to make the request again if it failed, and it just kept failing.

  • check that all the files from the export are getting uploaded to the server. check the console (f12) to see if there are any errors - probably 404 (file not found)

    This is what it says in the console. I don't know what the issue would be here, but I'll look into it.

  • Please post a screenshot of your code. It takes more time to request files from web, so if you are not using AJAX correctly, this may explain why it doesn't work.

    I think this might be it, I didn't even think of that. Thank you.

  • check that all the files from the export are getting uploaded to the server. check the console (f12) to see if there are any errors - probably 404 (file not found)

    I'll check that now.

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

  • AJAX works 100% perfectly until I export it to HTML, then it just doesn't pull the .json files it's supposed to, even though the files are in the build. It doesn't work on Itch.io, or the Construct Arcade, and it doesn't matter if I use the Scirra Arcade export option or not either.

    Has anyone had any issues with this, or maybe some insight that could help me figure out why it isn't working. I checked to make sure that both sites had HTTPS as well, which they do.

  • You can do this with blend modes:

    Dang, just figured it out too. I knew I had to use blend modes, but I wasn't sure exactly what to use.
