method
Anim.once
Anim.once(timer, fps, count) -> int
Like Anim.frame but for a one-shot clip: the frame is min(floor(timer * fps), count - 1), so once it reaches the last frame it stays there instead of wrapping. Use it for a play-once animation like an explosion or a door opening; pair it with Anim.finished to know when it is done.
Parameters
timerelapsed seconds (a fixed)fpsframes per secondcountnumber of frames in the clipExample
program Demo {
property Blast { timer: fixed = 0.0 }
model Boom { Blast }
handler Run phase Update {
Blast.timer = Blast.timer + Time.delta()
let cell = Anim.once(Blast.timer, 15, 6)
print(cell)
}
