... Uh, okay then.
There's one from 2008, before Blockland v9. It had a GUI (on a keybind) or chat commands for making bots with one of a few fixed behaviours and 'patrol paths', and a 'bot spawn' brick which made the same kind of bots and respawned them when they died. It worked with that version's Team Deathmatch. This one actually comes with a manual PDF, if you got it from the "right" place.
There's a different one from 2010 which had the listed events, plus some "Bot Spawn" bricks that put the events together to make a tiny AI. It worked with Team Deathmatch and Iban's ZAPT.
In both versions the AI had some silly details like only being able to see what's in front of it/"hear" shots passing by and chasing to where it last saw you. They could use different weapons (hold down fire on a Bow, click spam on a Gun, charge a Spear) and were really accurate with projectiles. (Trigonometry - "where are you going to be when this spear lands") They don't do any of the detailed "navigation" from the Slayer topic.
Both of them used the deprecated/buggy "AIConnection" class which has been removed from recent versions of Blockland - it's not worth trying to get them to run again.
