Lets Make A Retro Game – Episode 10 – Collision Detection

This is the 10th video in my series, where I am going to work through the steps required to make a home brew game for a retro 8-bit console or computer system.

In each episode I will work through various topics, such as tools, methods and design.

All of the information referenced in each episode will have an associated article on my web site.

In the Intellivision game of Astro Smash, that we are basing our game on, the main enemies are Asteroids that fall down the screen, exploding when they hit the ground.

Points are awarded to the player, when one is destroyed and points are removed if one reaches the planet surface.

In this episode we are going to introduce a collision detection, this will involve:

– Adding a collision detection function.
– Using it to detect when our player bullets hit one of the meteor.

I have included the complete code for this section, so you can follow through the various steps without having to worry about typing in code.

The supplied code has two folders:
Start – where we start in this episode and
End – the final code and a copy of the ROM file.

The corresponding article with all download links and more detail on what is covered in this episode is available on my website here:

Next episode we will be adding some collision detection so that our player bullets can hit the meteors.
