How to make a 2d game engine from scratch

It was after that experiment that I decided to create a little character with eyes and a mouth and then wrote a player class. At first the jump of the player was cone shaped and about a month later, I figured out how to make the jump into an arc, a month after that, I added legs to my little character and he could now walk and interact with other objects.

It was right there that I realized, hey, I can probably make a game out of this! I sat down with a book and started to create an architecture for a game engine and the many classes to make it work. I spent about another month writing documents and mock up code of ideas that could work, some got implemented others got thrown out the door. Every day I kept coming home and writing more code and doing more experiments, pushing the GDI to very limits to see what I could and could not do.

This project has required a lot of hard work and dedication on my part and a year later, I'm still working on it. If your making a 2d game engine, don't think that this will be a walk in the park, it is very very complex and others will actually encourage you NOT to do it a large majority WILL, there is a lot to be learned from it.

A lot of problem solving and a lot of fun and it will also strengthen your skills in which ever language you are using to make it because it will test you on every level. Anyway, yes it can be done but you have to be committed to it. Here is a video of my 2d game engine, if I can do it, so can you, feel free ask questions.

TimothyPidashev said: i want to know were to start on making a 2d game engine You start where every game engine starts, at the beginning.

Don't use scripting languages like Python or Javascript for desktop applications as they all come with certain penality. This is a web interface that behaves like a desktop app and can but must not be performing well too. The clue about using Electron is that you can use Javascript as UI and display logic and place your core code in a C assembly that will be embedded.

It is not worth to develop for Apple in my opinion because you have to buy Apple hardware first to legaly develop for Apple. I even believe that there will be a drop of it in the next major update of Unreal and Unity carries it because it looks llike they support much platforms.

They even have project support for Blackberry and some other legacy devices. I know that some Online Browser Games use Java Applets, some still require Adobe Flash to be present so it belongs to what dimension your game will have.

TimothyPidashev said: 2d game engine The math is similar to that used in 3D, you need to know the basics and should read this discussion. Instead you should add this as a side note and share your knowledge as a developer with those people, thats why we all are here It doesn't make sense to make Game Engines if you have zero idea on how to make actual games so I completely disagree with your comment.

TimothyPidashev said: Rutin I understand and i have another question if you dont mind. This topic is closed to new replies.

Josheir Internship Possibility Games Career Development. How do we pick the right one? Look at the number of stars on GitHub? The number of contributors? The number of published games?

Writing a game engine is not an easy task however. But this does not prevent us from doing animations. Click on the canvas and press A and D to move and W to jump. You can also click on the JavaScript tab to see the full code for this example.

Deploying a game like this is easy. The HTML only has two lines, one of which defines the canvas , and one defines a div used for debugging. Adding Lodash is either as well, all it takes is a single line to serve it from a CDN. Overall, the page to deploy the game could look something like this:. The core of the game loop is calculating dt or deltaTime , which is the time elapsed since the last frame. Every run of the game loop then updates all of the necessary logic.

If we keep dt in seconds, we can measure all velocities as per second and calculate the per-frame update by simple multiplication. For example, if we intend to change player. Starting with a solid foundation in Scratch ensures a successful path to more advanced scripting and game design. Leveling up from 2D games to 3D design offers a whole new world of possibilities.

It's one of the best ways to build your creativity and logical skills! Scratch is a high-level visual programming language. Making a 3D Scratch project does require previous experience with Scratch coding. First time with Scratch 3. Check out the following tutorials. Get up to speed and take your game design to the next level in no time:. The key is the illusion of depth. Since the platform is used to make 2D games, it offers X axis left and right perspective and Y axis up and down perspective coordinates.

Three-dimensional platforms add a third axis called the Z axis, which runs at a right angle to the X axis and Y Axis, to create depth. Unlike a true 3D engine like Unity and Unreal Engine, Scratch uses movement and size changes to create the illusion of depth. Scratch provides the functionality to build a 3D world with a 2D map. Once you've learned the techniques for 3D models and 3D characters, it's like magic!

For today's example, we'll show you concepts, scripts, and variables for making a 3D effect in Scratch using size and perspective to create a simple 3D maze. This is done through the process of raycasting.

Read more on how a raycaster works on Scratch Wiki. The two opening points are the "exits" of your game. To keep things simple, you can replicate the maze sprite example or even make one with less lines. Use an image to trace or draw your own. Whatever works better for you! Next, duplicate your maze sprite. Label it "exit" and trace lines at the exits. Then, delete the duplicate maze and leave the trace lines. Create a message that says "You Win!!! Use the code to trigger it when you pass the opening points "exits".

Again, to keep it easy, draw a basic box. You can then use your pick of movement code. To freshen up on this type of Scratch code, read about how to make a sprite move beginner and how to make a sprite move smoothly intermediate.
