channel

The channel namespace — 6 functions.

globals/channel/create

globals/channel/create(opts: ChannelOpts) -> number?

Register a keyframe channel. times is the sorted keyframe time array; values is the packed value array (layout depends on interp); stride is the floats-per-sample width; interp is "step" | "linear" | "slerp" | "cubicHermite". Returns the channel handle, or nil on malformed input.

globals/channel/destroy

globals/channel/destroy(handle: number) -> boolean

Drop the channel from the registry.

globals/channel/sampleInto

globals/channel/sampleInto(ch: number, time: number, buf: number, offset: number) -> boolean

Sample the channel at time and write stride floats into the Buffer's data starting at f32 index offset. Returns false on unknown handle, layout mismatch, or out-of-bounds; the buffer is unchanged on failure.

globals/channel/sampleManyInto

globals/channel/sampleManyInto(ch: number, time: number, buf: number, offsets: { number }) -> boolean

Sample once, blit the result into every position in offsets. Saves the per-offset binary search when one channel feeds many bones / particles / parameters.

globals/channel/sampleQuat

globals/channel/sampleQuat(ch: number, time: number) -> (number?, number?, number?, number?)

Convenience accessor for stride-4 quaternion channels.

globals/channel/sampleVec3

globals/channel/sampleVec3(ch: number, time: number) -> (number?, number?, number?)

Convenience accessor for stride-3 channels. Returns the three components as multiret, or nil if the channel is unknown / has a different stride.
