CleverCreeper

The mod changes Creeper behaviour on the server through a set of game rules prefixed with CleverCreeper. Explosion power can be tied to the Creeper's scale, so larger Creepers detonate harder. A follow range controls how far Creepers track a player, and an option lets them see through walls. Other rules allow Creepers to breach walls within a configurable distance, leap at targets the way spiders do, and set the minimum and maximum explosion power.

The mod was built as an update to an earlier Creeper AI approach, and it draws on the Epic Siege Mod idea of giving Creepers extra abilities such as bombing, fire explosions and powered jumps. Creepers can also spawn as powered variants, and the probability of that is configurable. Server owners who want more control over the threat posed by Creepers can adjust each rule separately.

Only the server needs the mod, so players join without installing it. It is required on the server and optional for players.
