trackEntry.shortestRotation

Type: boolean

See also: trackEntry

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.spine43")
local atlas = spine.loadAtlas("assets/characters/spineboy.atlas")
local skeletonData = spine.loadSkeletonData("assets/characters/spineboy.skel", atlas)
local spineboy = spine.create(skeletonData)

-- Set the "aim" animation on track 2 to use the shortest rotation
spineboy:setAnimation(2, "aim", false)
spineboy.tracks[2].shortestRotation = true

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

    spineboy:updateState(dt)
    spineboy:draw()
end

Runtime:addEventListener("enterFrame", onEnterFrame)
