trackEntry.mixAttachmentThreshold¶

Type: number

Overview:¶

When the mix percentage (mixTime / mixDuration) is less than the mixAttachmentThreshold, attachment timelines are applied while this animation is being mixed out. Defaults to 0, so attachment timelines are not applied while this animation is being mixed out.

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 "walk" animation on track 5 with a mix attachment threshold of 0.1
hero:setAnimation(1, "walk", true)
hero.tracks[1].mixAttachmentThreshold = 0.1

-- Transition to the "run" animation with smooth attachment mixing
hero:addAnimation(1, "run", true, 500)

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

    hero:updateState(dt)
    hero:draw()
end

Runtime:addEventListener("enterFrame", onEnterFrame)
