Speed Pads, Jump Pads and Conveyor Belts

You can find them under Entities, then "Speedpads + Jumppads" There are also 2 STOOLs "Speedpadify" and "Jumppadify" that turn the prop you click on into a speedpad or jumppad. If you rightclick a speedpad using context menu (C), you can change it to preset speeds or edit the properties to enter a speed number yourself. You can do something similar with jumppads using their properites menu. You can also do this on speedpadified or jumppadified props. There's a conveyor belt as well, for fun.
