Hey guys!
I’ve just tested Spine animation, due to extremely low perfomance it looks literally UNUSABLE (I’m not even sure if anybody from Corona users could ever use SpineLua in any actual project)
I’m getting only 22fps when I spawn just 10 objects (on a pretty good hardware, most of android users have much slower phones)
With such extremely low perfomance we can have maybe one or two Spine objects on stage, not more.
It’s literally hundred times slower than traditional frame-based animation.
Can you pls check my simple code snippet? Maybe something in my code is extremely inefficient?
My project resolution: 1280x720, I’ve attached my spine atlas&png&json to the post.
local spine = require "spine-gideros.spine" function loadSkeleton(atlasFile, jsonFile, x, y, scale, animation, skin) -- to load an atlas, we need to define a function that returns -- a Corona paint object. This allows you to resolve images -- however you see fit local imageLoader = function (path) local paint = { type = "image", filename = "data/" .. path } return paint end -- load the atlas local atlas = spine.TextureAtlas.new(spine.utils.readFile("data/" .. atlasFile), imageLoader) -- load the JSON and create a Skeleton from it local json = spine.SkeletonJson.new(spine.AtlasAttachmentLoader.new(atlas)) json.scale = scale local skeletonData = json:readSkeletonDataFile("data/" .. jsonFile) local skeleton = spine.Skeleton.new(skeletonData) skeleton.flipY = true -- Corona's coordinate system has its y-axis point downwards skeleton.group.x = x skeleton.group.y = y -- Set the skin if we got one if skin then skeleton:setSkin(skin) end -- create an animation state object to apply animations to the skeleton local animationStateData = spine.AnimationStateData.new(skeletonData) animationStateData.defaultMix = 0.2 local animationState = spine.AnimationState.new(animationStateData) -- set the skeleton invisible skeleton.group.isVisible = false -- set a name on the group of the skeleton so we can find it during debugging skeleton.group.name = jsonFile -- set some event callbacks animationState.onStart = function (entry) print(entry.trackIndex.." start: "..entry.animation.name) end animationState.onInterrupt = function (entry) print(entry.trackIndex.." interrupt: "..entry.animation.name) end animationState.onEnd = function (entry) print(entry.trackIndex.." end: "..entry.animation.name) end animationState.onComplete = function (entry) print(entry.trackIndex.." complete: "..entry.animation.name) end animationState.onDispose = function (entry) print(entry.trackIndex.." dispose: "..entry.animation.name) end animationState.onEvent = function (entry, event) print(entry.trackIndex.." event: "..entry.animation.name..", "..event.data.name..", "..event.intValue..", "..event.floatValue..", '"..(event.stringValue or "").."'") end if atlasFile == "spineboy.atlas" then animationStateData:setMix("walk", "jump", 0.4) animationStateData:setMix("jump", "run", 0.4); animationState:setAnimationByName(0, "walk", true) local jumpEntry = animationState:addAnimationByName(0, "jump", false, 3) animationState:addAnimationByName(0, "run", true, 0) elseif atlasFile == "raptor.atlas" then --skeleton.vertexEffect = spine.JitterEffect.new(5, 5) skeleton.vertexEffect = swirl animationState:setAnimationByName(0, animation, true) else animationState:setAnimationByName(0, animation, true) end -- return the skeleton an animation state return { skeleton = skeleton, state = animationState } end local allSpineLuaObjects={} local function spawnSpineLuaObject() allSpineLuaObjects[#allSpineLuaObjects+1]=loadSkeleton("rooster.atlas", "rooster.json", math.random(160,570),math.random(160,1100), 1, "rooster\_run\_anim") end Runtime:addEventListener("enterFrame", function(event) local delta = event.deltaTime for i=1,#allSpineLuaObjects do allSpineLuaObjects[i].state:update(delta) allSpineLuaObjects[i].state:apply(allSpineLuaObjects[i].skeleton) allSpineLuaObjects[i].skeleton:updateWorldTransform() end end) for i=1,10 do spawnSpineLuaObject() --I'm getting only 22fps on a decent phone hardware :( end
