The Typewriter package contains 2 main parts, the typewriter component itself and a speech bubble prefab. The typewriter component provides a configurable typewriter style effect that can be used on any GUIText or TextMesh. This is useful for character speech bubbles, story text, instructions, and a myriad of other uses. The speech bubble prefab uses the typewriter effect combined with other scripts to to trigger the speech bubble when the player gets nearby and hide it when the player moves away or when the text writing effect completes. These components can be used 100% without scripting but are also easy to modify if you need something more customized.
