Type: number

See also: trackEntry

Overview:

allowing you to start the animation from a specific frame or point in time.

Example:

---

local lastTime = system.getTimer()

local spine = require("plugin.spine")
local atlas = spine.loadAtlas("assets/characters/hero.atlas")
local skeletonData = spine.loadSkeletonData("assets/characters/hero.skel", atlas)
local hero = spine.create(skeletonData)

-- Set the "charge" animation on track 1 to start at 1.5 seconds
hero:setAnimation(1, "charge", false)
hero.tracks[1].animationStart = 1500  -- 1.5 seconds in milliseconds

-- Update the animation state each frame and monitor animation time
local function onEnterFrame(event)
    local time = system.getTimer()
    local dt = time - lastTime
    lastTime = time

    hero:updateState(dt)
    hero:draw()

    -- Monitor animation playback
    print("Animation Start Time (ms):", hero.tracks[1].animationStart)
    print("Current Track Time (ms):", hero.tracks[1].trackTime)
end

Runtime:addEventListener("enterFrame", onEnterFrame)
