trackEntry.shortestRotation¶

Type: boolean

Overview:¶

If true, mixing rotation between tracks always uses the shortest rotation direction. If the rotation is animated, the shortest rotation direction may change during the mix. If false, the shortest rotation direction is remembered when the mix starts and the same direction is used for the rest of the mix. Defaults to false.

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 "turn" animation on track 2 to use the shortest rotation
hero:setAnimation(2, "turn", false)
hero.tracks[2].shortestRotation = true

-- 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)
