The zombie is a respawning monster. There are two different types of zombies: normal and hard. They behave mostly the same, but there are slight differences that make the hard version more aggressive.
Behavior
Zombies can be in one of three states:
- Wandering: Walk in a straight line in a random one of the four orthogonal directions. Zombies start in this state.
- Following wall: Go counterclockwise around the perimeter of a wall. A zombie will enter this state if it touches a wall (i.e. a tile that is solid to monsters) while in the wandering state.
- Targeting: Move towards the nearest targetable sprite. A zombie enters this state when it comes within a certain distance of a targetable sprite. The zombie will leave this state and go back to the wandering state if there is no longer a targetable sprite within another (slightly larger) distance.
Zombies will despawn if they are a distance of 208 pixels or more on a single axis from the closest player, and are not within target range of any targetable sprites. The SNES screen has a width of 256 pixels, so this means it is possible for a zombie to despawn while still on screen if all players are on the very left or right of the screen and the zombie is on the opposite side.
Differences in hard version
Major differences
- Start targeting at distance of 159 pixels (instead of 64 pixels for normal). They continue targeting while there is a target within 179 pixels (instead of 69 pixels for normal).
- Moves at a speed of 1 px/frame when wandering and following wall (instead of 0.5 px/frame for normal). The speed when targeting is 1 px/frame for both versions.
Minor differences
![](http://static.miraheze.org/zamnhackingwiki/5/5c/Zombie_follow_wall_comparison.gif)
- Position update logic is different when targeting. When targeting through a wall, normal zombies will get stuck, but the hard version will still follow along the wall.
- The angle to rotate when following a wall is stored in a variable instead of being hardcoded. However, this variable is never initialized, so it will retain whatever value happened to be in RAM previously. This generally results in the zombie sticking to the wall instead of following it.
- Will switch to the wandering state if they are unable to move towards the target when targeting (because there is a wall in the way). The zombie will still likely be within target range, so it will usually immediately switch back to targeting, resulting in the zombie turning in place spastically.
Animation
Zombies have a four frame animation cycle, with 8 frames in between each animation frame. There is a separate set of animation frames for each of the 4 orthogonal directions, chosen based on which direction the zombie is moving. If the zombie is moving diagonal, it uses the left or right animation.
Bugs
- Hard zombies do not generally follow walls like they should. See Differences in hard version.
- The hard zombies have a partially implemented feature that appears to be something that would make them stop targeting for a certain amount of time. In its incomplete state, it generally does not affect their behavior, but if a zombie stays following a wall for around 9 minutes, the timer will underflow. This will cause the zombie to stop targeting for around another 9 minutes until the timer reaches zero again.
