Sometimes your game or canvas experiment might have one or more layers of animating backgrounds that are set in motion for the player’s movement or some other reason (like creating a parallax effect?). Just had to do something similar the other day. The problem is tricky but with a bit of thinking it seems like I came up with a proper solution!

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!

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.
Limiting the frame rate while using requestAnimationFrame can be a common want especially when coding Games where you want your animations and mechanics to not exceed a particular mark of frames per second. Let’s go through 2 ways of doing it.

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!

One of my previous posts talked about implementing gravity in our canvas experiments. Eventually, we made a realistic bouncing ball. We’ll kind of extend that experiment to make a quick fountain explosion on canvas obeying gravity.

Writing Text on canvas is pretty straightforward. All we need to know about is certain properties and methods that are pre-defined on the canvas’s context. You can draw/write all unicode characters using the related methods.
