Make your own animations with the Deekay Tool: aescripts.com/deekay-tool/
Creating a sidescroller type Mario game requires a bit of knowledge related to physics, collision detection, and sprite animation. It can be quite tricky at first, but once you understand the basics, you can set up some full-fledged levels which anyone can play.
This tutorial will teach you everything you need to know in regards to developing a fully functional Mario-type game with just HTML5 canvas and vanilla JS.

@losrobbosful Год назад

I reaaaally love how you scale up the complexity of the game very very cautious and carefully, introducing concepts with as much depth as necessary instead of just dropping concepts in randomly. That makes your tuts really outstanding. Hope you will also do more on BabylonJS again :D

thx for yet another excelent tutorial! I'm loving your lessons, programming has been fun once again ^^ tip, for death pits u could just reset player Y and X position back to 0, 20 to get back where u started on the screen. and reset objects to their positions so the entire screen gets realocated to their original position, too. reset objects first, or else your player could land on another death pit and fall into a loop depending how u designed the level. it fits all kinds of levels this way.

Great tutorial, including refactoring as a part of the process instead of skipping through made this whole project doable for a web dev noob like me. All of my previous experience was in hardware oriented projects using Arduino/C++ or RPi/python. This was a perfect introduction to JS. Almost finished re-skinning the game with my own image assets but got hung up working with Deekay Tool, I'll get there eventually, zero experience with AE probably isn't helping. Subbed!

Little tweak to add the effect of 'friction' to the player: if(keys.right.pressed) { player.velocity.x = 5; } else if(keys.left.pressed) { player.velocity.x = -5; } else { player.velocity.x *= 0.9; }

@muhammadasyrafi9550 2 года назад

Great tutorial! Thank you so much! It helps me kickstart my Javascript learning journey. Just want to add a little tweak I did on my attempt. If you hold the "UP" key, it will make your "player" kind of flying. I added *if (event.repeat) { return }* to prevent holding the *UP* key sending the player flying. It goes something like this: addEventListener('keyDown', ({ keyCode }) => { switch (keyCode) { case 38: if (event.repeat) { return } player.velocity.y += -20 break } }) note: I bind the key *UP* instead of *W* hence the *case 38*

@ruairidhgrass3479 Год назад

@ruairidhgrass3479 Год назад

Found a fix for the double, triple quadruple jump issue! I created a new condition on the Player class called 'onPlatform' and set it to true by default. This condition will return true if the player is touching a platform and false if the player if not touching a platform. To do this I wrote a small conditional within the player.update() function which goes like this: this.velocity.y !== 0 ? this.onPlatform = false : this.onPlatform = true Then in the addEventListener case statement for "keyDown" I amended the "w" case like so: case "w": case " ": case "ArrowUp": player.onPlatform === true ? player.velocity.y -= 15 : null break; No the player wont be allowed to take more than one jump :D

@killroy1986 2 года назад

Hey Chris! Great content, thank you so much, I learned a lot. A question... I'm wondering, even though it's just a 2d platformer, ideally, would it make sense to implement a game like this in webgl using matrices? Or it's just simply overkill? Not for learning purposes, I'm just wondering if that would be the best way since as you improve as a game dev, you might want to add a lot of special effects, particles stuff like that. Alright, I know it's always "it depends" so I'd rephrase my question... If you were about to write a very modern 2d platformer with lots of moving stuff on the screen, would you use three.js or, unless it's 3d, the 2d rendering context is totally fine. Thank you in advance!

@milena9356 9 месяцев назад

for anyone who had problems when he starts the server at first you have to know that he runs the code on git bash, that was my first mistake. After that I had several errors after "npm start", but to you solve it (if it's the same as mine) i had to run ' export NODE_OPTIONS="--openssl-legacy-provider" ' and to make sure that the environment variable has been set, you can run ' echo $NODE_OPTIONS ' , if you see ' --openssl-legacy-provider ' its ok and you can run 'npm start' again *dont forget that you have to run all these codes in mario-game-server folder, and they're valid for windows

Working with collisions was interesting and allowed me to play around with the values. But the topic of using sprites was a bit confusing and requires a separate theoretical breakdown. You need to put theoretical elements and a bit of history into courses as you did before. The main problem for beginners is the inability to set up a local server. An up-to-date guide is needed.

im a bit of a begginner, so i have some questions. in 13:50 he creates the update function. is it a function or something else? its not stored as a var/const and doesnt have the word function in the declartation. is it something else or just a way of writing functions i havenst seen before. also the html page had nothing but a canvas tag and it still functioned propperly. do you not need the html/head/body tags?

@patrickconrad2874 2 года назад

So keyCode is depricated. Not sure if he mentions this in the video later on. Will there be any weird side effects if I just use the code property? I guess I'll need to account for other language keyboards but idk if that is an issue with keyCode still too.
