Different Tools for Our Sketching Application

It is important for our painting application to have different tools like:

  • Line tool to draw straight lines.
  • Rectangle tool to draw rectangles.
  • Circle tool to draw circles.
  • Eraser tool for erasing purposes.
  • Color tool to choose colors.
  • … and more

We have already built our pencil tool in previous parts. In this part, we’ll focus on creating the aforementioned tools.

Optimizing HTML5 Canvas to Improve your Game Performance

So I coded a game this month for the github game compo called “Pappu Pakia“. This is my first HTML5 Game with beautiful graphics by Kushagra. When I was finished with the coding part, it was pretty exciting until I played it a few times when my CPU was busy, then on an old laptop and finally on a mobile device. In all the cases it was laggy, except in the last one where it was super slow. So what do we do now ? Time to Optimize!

HTML5 Canvas and Friction

So you started moving an object on your canvas by manipulating vx and vy, i.e., velocity on the x and y axis. But then, you just realized that in real world scenarios the speed of an object reduces with time, if there’s no continuous acceleration. Even with an acceleration of X, there will be some friction faced counter-affecting the acceleration.

Basics of Implementing Gravity with HTML5 Canvas

Gravity

When creating some canvas experiments like a particle emission system or a game, gravity can be a key feature to implement. Figuring out how to implement gravity on an object in terms of coding can be a bit confusing. We’ll try to comprehend it, by putting it into code in a simplified manner. I liek simplicity!
