Created an enemy object, and a container object to hold the enemies. For now to keep things simple, each room has its own enemy array. This means that enemies can’t move between rooms (without a lot of extra coding).
Used another simple model I rendered in Blender as the enemy sprite. For now, it just moves left and right across the room. Above the enemy, a number is displayed followed by its representation in binary. As the player correctly shoots the binary code, the bits (0’s and 1’s) change from green to red. Once all the bits are red, then the enemy dies. If the player incorrectly shoots a bit, then the enemy becomes angry for a short period of time and moves faster.
