### Parameter Types

Name	Description
`a`	Amplitude, the strength of an effect. A higher amplitude creates a stronger effect. For example: the height of a wave, the amount shake offsets letters.
`d`	Delay, the time in seconds before the effect starts.
`f`	Frequency, the speed of an animation. A higher frequency creates a faster effect.
`l`	Limit, the number of cycles (or seconds for animations without cycles) before the animation stops.
`w`	Wave Size, for effects that work in waves (`<wave>`, `<rainbow>`, etc.). For example, a wave size of 5 means the full wave will be completed after 5 letters.

## Examples

Code	Explanation
`Example <wave>text</wave>!`	`text` is animated as a wave, it uses default parameters.
`<wiggle>Example</wiggle><wave>text</wave>`	`Example` wiggles with default parameters; `text` waves with default parameters
`<wave>Example <swing>text</swing></wave>`	Animations can be combined
`<wave f=5>Example</wave>`	`Example` waves 5 times per second.
`<wave a=3 d=3 f=5 w=10>Example</wave>`	`Example` waves with an amplitude of 3 (very large), a frequency of 5, and a wave size of 10 letters. The animation starts 3 seconds after the text appears.

## Performance cost The type and amount of animations you use should not significantly impact performance. Most of the performance cost is up-front when you set your text and is mostly dependent on the length of your text. Check out the [performance-optimization-guide](https://docs.stixgames.com/text-animations/performance-optimization-guide "mention") for more information. *** Check out [custom-animations](https://docs.stixgames.com/text-animations/animations/custom-animations "mention") and [custom-c-animations](https://docs.stixgames.com/text-animations/c-extensions/custom-c-animations "mention") if you want to extend the asset with your own animations.
