First off There is a way to do this
without ply's mod. I was just being selfless and keeping it for myself, but now I think that you all should know.
WARNING!!! : This work around my cause glitching where the player will freeze to one spot.
Now the code is simple,
:plrwithinzone=1,random=3:plrfreeze=1
:plrwithinzone=1,random=6:plrfreeze=0
This snippet of code creates a feel that the player has slowed down. Change certain variables, such as the random variables, to make him slower.
And as an add-on note: I used this snippet in hockeykid's water script to slow the player down under water, in other words it works.
