I write little tutorials for my students. currently I'll create a small demo cp3 file and the guide is usually a one or two page Word file, or an html page in a VLE.

I've been working with .md files and it occurred to me how handy it would be to write a short guide in markdown and put it in my Construct project Files folder as something students could have open in a project tab.

Is it possible to view md files while a construct project is open?

Alternatively, could I save an html file into files and allow it to open for reading instead of editing? Possibly opening it in read view for existing files, and have an edit mode option or something?

I suspect these are more feature requests than something I can do now?

Allan.

Ok, back at it. I would like to use TensorFlow Body-Pix to segment the webcam image.

I'm picking at a range of tutorials, including this: blog.tensorflow.org/2019/11/updated-bodypix-2.html

Within my main.js script before anything else happens I tried the following two lines, and both failed with the same result:

//import * as TensorFlow from 'https://cdn.jsdelivr.net/npm/@tensorflow/tfjs@0.13.3';
import * as TensorFlow from './tf.js'; // local copy in script folder
/*
Uncaught TypeError: Cannot read properties of undefined (reading 'tf')
 at tf.js:2:149

*/

Quick FYI for those interested. Uninstalling Cheese fixed my ps2 eyetoy webcam issue.

OK, progress so far. Looking into the use of face-api.js to do this, with a chroma filter applied to green screen the background. my plan is to extract the face area, then make all the green bits transparent.

Work in progress, but getting there. I've hit a bit of an issue. This needs to run from a Linux machine.

I have Linux Mint 21 Xfce installed on an old PC, with a PS2 EyeToy set up as webcam. The webcam works well with other applications such as Cheese, but when I try to access it from my construct 3 game, I get nothing.

Permissions pops up, and I click the button to approve access, but nothing shows in the user media preview, and no pic is captured when I press a button.

This works on Windows 10/11 but on Linux I get no picture back with Chromium or Firefox.

Any advice welcome.

As a novelty, I would like to extract a face from a webcam, put it into a sprite, and pin it to the player's sprite as its head.

I have a User media object and sprite object, and a keyboard object.

At first I thought maybe I could use a green screen, then add an effect to replace the green colour from the image with a transparent alpha colour, but this is not working so well.

Then I figured, how about if I put an oval over the usermedia cam stream, and ask the player to position their head inside the oval? I could then use only the image data inside the oval in my sprite image. I have no idea how to tackle this so looking for any suggestions.

This is for students and high school kids studying at our college campus to play with and possibly implement in their game projects. Some of my previous students had a hoot using cropped side-on headshots of themselves on their platform characters. It would be so cool to integrate the capture process in their games.

All the best,

Al

Thanks for the info fedeca, much appreciated.

It does look somewhat complex; I shall digest and share my results once I've got somewhere.

Sorry, further information on this. the issue was where the student had a sprite spawn a single 8x8 pixel bouncing ball bullet sprite, the bullet sprite was not visible on screen at 240hz.

Ah, thanks dop2000. That sounds perfect, I'll try that. Didnt even realise C3 had a canvas object. Thats just opened up a whole world of possibilities!

Hi, I've been searching for this but haven't found an answer yet.

Currently, if I create a demo with explosions or damage impact, I spawn small groups of tiny sprites which stick to damaged player, npc, or destructible sprite objects; as scorch marks or surface damage. These are pinned to the surface of a sprite until it is destroyed. These tend to be 4x4 pixel black or grey dots, so its a lot of resource having each one as a pinned sprite.

A more effective way to do this would be to draw directly into the frames of the current sprite instance.

E.g.

bomb - on collision with - building ... thisBuilding.animations.frames(0).drawRect(x1, y1, x2, y2, colour_code)

Is this possible in construct 3?

Could I read a pixel colour value and use that to darken and increase transparency?

Many thanks,

Kinnon
