Speed

Speed is a weapon and tool value that determines how long it takes for an item's animation to complete. Terraria's engine determines speed using the useAnimation value - 1 useAnimation increment equals 1 frame or 1/60 of a second. An item with a useAnimation of is used in one second, or 60 frames with Terraria running at 60 frames per second (FPS). Running at 30 FPS, the same item requires only 30 frames.

The useAnimation value ranges resulting in each speed are to the right.
