Ilysa by Example: Sequence

Ilysa by Example: Sequence - Context

Within a sequence, the context value `ctx` contains values useful for creating lighting effects. A full list of available values can be viewed here.	package main
	import ( "fmt"
	"github.com/shasderias/ilysa" "github.com/shasderias/ilysa/beatsaber" "github.com/shasderias/ilysa/context" "github.com/shasderias/ilysa/timer" )
	func main() { m, _ := beatsaber.NewMockMap(beatsaber.EnvironmentOrigins, 120, "[]") p := ilysa.New(m)
	p.Sequence(timer.Seq([]float64{0, 1.5, 2.5, 3, 4}, 6), func(ctx context.Context) { fmt.Printf("%4.2f %4.2f %1d %4.2f %t\n",
`ctx.B()` returns the current beat. `ctx.T()` returns the current position in the sequence, on a 0 to 1 scale. `ctx.Ordinal()` returns the ordinal number of the current beat, i.e. 0, 1, 2, 3… etc. `ctx.SeqNextBOffset()` returns the number of beats to the next beat in the current sequence. As a special case, when using `timer.Seq()` to specify a sequence, on the last beat, `ctx.SeqNextBOffset()` returns the difference between the last beat and the ghost beat. `ctx.Last()` returns true if this is the last beat in the sequence.	ctx.B(), ctx.T(), ctx.Ordinal(), ctx.SeqNextBOffset(), ctx.Last()) }) }
