Welcome! The goal of this workshop is to introduce some basic patterns in game programming through a simple exercise. Some concepts that you will go through:

• The game loop
• Input & Movement
• Collisions & Physics (super super basic ver.)

At the end, you will create something that looks like this:

A green circle representing the player, that can move using WASD and shoot where the mouse is at upon left clicking. And red circles representing enemies that move towards the player, which upon contact, the player dies and the game is over. Player wins by killing all the enemies.

Let’s begin by downloading the starter project from here:

<aside> 💡

For mac users:

• Make sure you have clang installed (easy way is to install using Xcode command line tools).To check, open terminal and enter clang --version and if a version comes out, you’re good to go. (This also auto installs make)
• All you need to do is to run the make run in the directory to build and run.
• Alternatively you can also just use vscode and press f5 to debug and run.

For Windows users:

• Make sure you have gcc installed. To check, open command prompt and enter gcc -v and if a version comes out, you’re good to go.
• Run the build.bat script. (DO NOT USE THE MAKEFILE)
• Alternatively you can also just use vscode and press f5 to debug and run.
• If the build doesn’t work, it is likely because your version of gcc is outdated. </aside>
