Start Your Coding Journey Now! Go ahead, try it out! You can play it right here on this page:. I recommend downloading the source code for the example game so you can follow along. You may have noticed the strange '[name]. They include Webpack filename substitutions : [name] will be replaced with the entrypoint name which is game , and [contenthash] will be replaced with a hash of the file contents.
We do this to optimize for caching - we can tell browsers to cache our JS bundles forever, because if the bundle changes its filename will change, too the contenthash changes. The final result is a filename like game.
The webpack. We use webpack. I recommend installing the project on your local machine so you can follow along with the rest of this post. Setup is simple: first, make sure you have Node and NPM installed. The dev server will automatically rebuild the JS and CSS bundles when you edit code - just refresh to see your changes!
To start, we need an index. Ours will be pretty simple:. The meat of our client-side logic resides in those other files that are imported by index. The main idea is to keep an assets object that maps a filename key to an Image object value. When an asset is finished downloading, we save it to the assets object for easy retrieval later. Finally, once each individual asset download has resolved meaning all assets have been downloaded , we resolve downloadPromise.
With downloading assets out of the way, we can move on to rendering. Our game is pretty simple, so all we need to draw is:. Note: my old example code here uses setInterval , but you should actually use requestAnimationFrame instead. The specific implementations of the individual render helper functions e. Our control scheme is very simple: use the mouse on desktop or touch the screen on mobile to control the direction of movement.
This section is the most advanced one in this post. It will stop the function from doing anything if the animation is running. Create a function called checkDead that gets the position of the block and character, and then evaluates if they are on top of each other. If they are, then end the game. Create a variable called characterTop that is equal to the top value of the character div.
Now, this would return a string with a value such as px. Create an interval function that runs the checkDead function every 10 milliseconds. Now you have a fully functioning game. There is a link to my GitHub if you want to copy the code. You can also check out my YouTube video if you learn better visually!
Debugging code is always a tedious task. But the more you understand your errors the easier it is to fix them. LogRocket allows you to understand these errors in new and unique ways. Our frontend monitoring solution tracks user engagement with your JavaScript frontends to give you the ability to find out exactly what the user did that led to an error.
Understanding the impact of your JavaScript code will never be easier! Why do you have different lines of code in your github? Please friends check that video on YouTube. This is exact copy of that game.
