Let’s Make A Retro Game – EP11 – Scoring

This is the 11th 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 to make our scoring work we are going to need five things:

– A routine to display the current score to the screen
– A routine to add to the players score
– A routine to subtract from the players score
– Call the display routine when we are allowed to draw to the screen
– Call the routines to add and subtract points to and from the players score at the appropriate places in our game.

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 making so the player’s ship can be destroyed by the enemy objects and to keep track of our remaining lives.
