Our main loop is pretty much the same with some adjustments. Here we’ll be redoing the previous tutorial with atomic counters. If the compiler complains that it can’t find SDL. Here we’ll make our window jump from display to display.

This article is here to give you an idea where to go to help you out on your journey. Since this is a single source file program we don’t have to worry about it too much.

If it does we correct it. Become a Redditor and subscribe to one of thousands of communities. Lesson 12 Color Modulation.

Minimum Text Submission Length 40 words or so. For a dynamically linked library, these addresses are in the library file.

The reason we’re doing it here is because we want the source code to be as simple as possible, but in large projects global variables make things more complicated. His tutorials are very detailed and also easy to understand. Here we’ll be setting a function to be called back after a certain amount of time. The images we’re going to be dealing with here are the screen image what you see inside of the window and the image we’ll be loading from a file.

After your program is compiled and linked, you need to be able to link against the library when you run it. This means you want your code to be in neat chunks that are each easy to debug and reuse. If not we then check if the tile type number is valid.


Become a Redditor and subscribe to one of thousands of communities. In order to run a dynamically linked application, you need to be able to import the library binaries at runtime.

Approach to doing Lazy Foo’s SDL2 tutorials : gamedev

By default, most rendering systems out there are double buffered. Lesson 15 Rotation and Flipping. Since it was a small program we can get away with that, but in real programs like video games you want to have your code as modular as possible. Here we’ll using SDL 2.

When we render we only want to show tiles that are in the camera’s sight: To put a game together you need problem solving skills and that’s something you learn through experience.

By the end of these tutorials, you’ll know the basics to make your first real video game! Here we’re defining some constants. Notice that these are pointers to SDL surfaces. In order to program to link properly, it needs to know the addresses of all your functions including the ones for SDL. If it is valid we create a new tile of the given type, if not we print an error and stop loading tiles. Our media loading function will also be initializing tiles so it need to take them in as an argument.

Like Lazy Foo’ Productions on Facebook: We read a number into the tileType variable and then check if the read failed.

SDL is more likely to stay maintained since it’s supported by companies like Valve. Is lazy foo an okay resource to learn SDL? Here we’ll be loading an image to render it using textures.
