# Functions
## Scripts
You can control scripts programatically. This is the core concept of Topos after all!
- <ic>script(...number: number[])</ic>: call one or more scripts (_e.g. <ic>script(1,2,3,4)</ic>). Once called, scripts will be evaluated once. There are nine local scripts by default. You cannot call the global script nor the initialisation script.
- <ic>clear_script(number)</ic>: deletes the given script.
- <ic>copy_script(from: number, to: number)</ic>: copies a local script denoted by its number to another local script. **This is a destructive operation!**
${makeExample(
"Calling a script! The most important feature!",
`
beat(1) :: script(1)
`,
true,
)}
${makeExample(
"Calling mutliple scripts at the same time.",
`
beat(1) :: script(1, 3, 5)
`,
false,
)}
## Math functions
- <ic>max(...values: number[]): number</ic>: returns the maximum value of a list of numbers.
- <ic>min(...values: number[]): number</ic>: returns the minimum value of a list of numbers.
- <ic>mean(...values: number[]): number</ic>: returns the arithmetic mean of a list of numbers.
- <ic>limit(value: number, min: number, max: number): number</ic>: Limits a value between a minimum and a maximum.
## Delay functions
- <ic>delay(ms: number, func: Function): void</ic>: Delays the execution of a function by a given number of milliseconds.
${makeExample(
"Phased woodblocks",
`
// Some very low-budget version of phase music
beat(.5) :: delay(usine(.125) * 80, () => sound('east').out())
beat(.5) :: delay(50, () => sound('east').out())
`,
true,
)}
- <ic>delayr(ms: number, nb: number, func: Function): void</ic>: Delays the execution of a function by a given number of milliseconds, repeated a given number of times.
${makeExample(
"Another woodblock texture",
`
beat(1) :: delayr(50, 4, () => sound('east').speed([0.5,.25].beat()).out())
flip(2) :: beat(2) :: delayr(150, 4, () => sound('east').speed([0.5,.25].beat() * 4).out())
`,
true,
)};
`;
};
