Devlog 4: Getting to a working version

Like mentioned in my last Devlog, one thing I had to do was adding interaction based on color and distance, and hurray! I did both!
So I did it by having an array of floats, which contains the attraction matrix, but flattend, and did the same for the distance values, basically like this:
array[i + j * width] = matrix[i][j]
I also made a function that based on a minRange and maxRange around a particle calculates it’s attraction to other particles, if it’s closer than minRange, it gets pushed away, otherwise if it’s closer than maxRange, it gets attracted or repelled based on the attraction matrix.
I made it so instead of using Time.deltaTime it now uses a fixed value that you can change, and added friction, so the particles, making the particles alot more stable than they’d be otherwise.

So now, I’d have a usable version of Particle Life, but as you can see my To-Do list isn’t quite finished yet.
To-Do:

• Add interaction based on color and distance.
• Optimize and Improve calculations.
• Add an GUI / Interface
