(sorry for my english)
i create Basic R15IKFootplant by using this Raycast method https://devforum.roblox.com/t/ikcontrol-footplant-and-strafing-for-rig-15/2221813
make it Enabled when Humanoid Not moving

Please format your post properly beforehand, it’s simply horrible to read currently.

Edit: The author already fixed it, so this is not an active complaint anymore.

…he gave it for free. What more could you possibly demand? This isn’t even constructive criticism nor feedback.

A readable post.
I was not judging the content he shared, but how it was presented. The price is not a relevant factor in this context, so I’m not sure where you’re coming from.
Besides, he already fixed it so it’s fine.
