Getting Mr Bunny Roblox Working
I ran into this a few months back when a friend pointed me at some Roblox placeable props that were supposed to behave like actual characters in-game. The files themselves aren't complicated, but getting them to work right required a few steps most people gloss over. First you need the actual model files. There's a popular set floating around on the Community Create section, and I grabbed version 2.1 because the earlier one had some weird collision issues where the bunny would clip through floors at certain spawn points. What most people miss is the parenting structure. The script and mesh need to be nested correctly or the AI behavior won't trigger. Drop the .rbxm file into your workspace, then open it. Make sure the Script folder is inside the Model folder, not just sitting in StarterCharacterScripts. I spent about twenty minutes troubleshooting a broken path before realizing I'd dropped it in the wrong place during my first attempt.
The configuration happens in the control script. Open it and look for the spawn parameters. You want to set patrol_radius to somewhere between 8 and 15 studs depending on how tight your map is. Anything higher and the AI gets confused by walls it can't see through. Also set the interaction_timeout to around 4 seconds. The default is 2, which makes it seem like the bunny ignores players who are moving too slowly. There's one edge case worth knowing about. If you're putting multiple bunnies in the same area, they tend to pathfind into each other and freeze. The workaround is simple: assign each one a different zone_id value in the config. I found this out after my second playtest when three bunnies ended up stuck in a corner loop that crashed the server instance. For the visuals, make sure your lighting mode is set to Shadows or the textures look washed out. The model was baked with a roughness map that doesn't play nice with the default Roblox lighting. Switching to a manual lighting setup takes about five minutes and makes a noticeable difference.
If you're looking to download, the main thread is on the Roblox Developer Forum under the asset marketplace section. There are also some forks on GitHub if the original author takes it down, which they occasionally do for licensing reasons. I'd recommend keeping a local copy once you find one that works.
