Moves the entity to the specified position.
If the new position doesn't take effect right away, you can use Entity:SetupBones to force it to do so. This issue is especially common when trying to render the same entity twice or more in a single frame at different positions.
Setting a player's position with this function only works serverside
Sets the player's position to (0, 0, 0)
Entity(1):SetPos( Vector(0, 0, 0) )
