Canvas has been something I wanted to make games with for a while now. It can be tough to put the time into it when you are focusing on other things, but every now and then I get to sit down and play around. But I have learned a few things, so lets see if I can help you too as well!.
So to begin, you can find an example of the game here https://github.com/Rchristiani/Space. I will be creating a separate repo for the game, so that you can see the code as it is from part to part. The game we will be creating will be very simple. We will have a few key features:
1. Player movement from input
2. Getting the player firing bullets!
3. Getting the enemy to fire back.
So in the end we will have a simple game. You have your players ship, it can move up and down and left and right etc, you can fire bullets, and we will have an enemy that can fire back at us. Super simple but pretty satisfying to get set up. Lets dive in!
