I just realised there could be a way to create custom player animations, while maintaining your avatar.
You know how the beta player matches your avatar? Well, if we got our current blockland retail player model, then add the blockland body parts such as helmet, hat and others, get them to match the avatar like how the beta player does, and then animate the model that looks the same like the default one.
I'm saying, animate a copy of the default playermodel on Blockland.
I'm sorry if it's hard to understand
