How do i make my crouch animation actually croutch [Read DESC]?

im going to reales my new game soon and I made a crouch animation...but you see when I crouch and try to go under the spikes I still die... :( what can I do to prevent this from happening...…?

Try moving the Humanoid Root Part down a little using CFrames. I don't think animations actually change the hitboxes of a player. Another thing you can try is when you touch the spikes, check if an animation is being played. If one is being played, don't deal any damage.
