For regular users (non-modders) it doesn't access the species-specific behaviors in aschar because it lacks that tag - it's a pretty minor change that makes the character accessible to the user-end and potentially usable in actual mods; if you were going to use Robbert as a character in a mod, you'd need to add that tag anyways - if a player wanted to play as him in any level that involves jumping, they basically just wouldn't be able to with that. I dropped an updated .xml file for a user in the Wolfire Discord the other day, but I think just updating it on the mod/workshop end would be the best option for making the content accessible for everyone.

I'll think about it.

@Mystery, I know you aren't the original mod author, but would you be willing to consider adding a <species> tag to the character xml so that it can actually jump like a rabbit and be usable for players? I'm sure RagdollZombie would have wanted people to be able to use it.

The jump height is way too low, other than that this is a pretty nice mod that could give some people nostalgia about the good ol' alpha days of this game.

Nice

Yes, that

Some context: it was the original rabbit from the beginning of the development of the game, which has custom movements
