How to make a clean NPC ragdoll?

#1

howdy fello roblox devs! i have been trying for so long now but i just cant seem to make a clean, smooth, crispy ragdoll that satesfies you as you slap someone across the face in a roblox game. anyway, heres what i would LOVE for it to look like (i know it probably wont look this good and i dont think its roblox):


and heres what it looks like currently, the biggest problem at play currently is the lag from the npc as they start walking and when the ragdoll starts:

i really want to clarify that it looks fine if its on a player, its the NPC specifically that im trying to make look spicy. also its all server sided, as i tried client replication and it really does suck. for anyone reading this who would like more resources (videos, code, etc.) i would be more than happy to provide! i really appreciate you guys looking at this post and please do not hesitate to let me know if you have knowledge about this topic!

You’ve already posted this once, update that post… instead of creating a new one. Plus, if you want better assistance, provide code in your post.

Regarding Ragdolls, most people don’t like helping regarding ragdolls as they’re very tedious to deal with. With you having an issue with bots, I’d recommend adding a copy of your place so people can test different methods of ragdolling your bot.

Ragdolls in roblox feel unatural because characters feel like they are weightless. You can try messing with custom physical properties and make more rigid joints.

It usually is done by adding a slight impiuse in the direction your character is walking or moving in. If it’s walking then feet else if they are shot or slapped then at the point of contact.

For more realism you can make an animation and make the character move around a bit in the direction of the force.
