Tweeners in Lua

您必须具有最少的代码集才能在 Scripted Entity Tweener 系统中播放动画。将此脚本用作 Lua script 组件的一部分。有关 Lua 脚本组件的更多信息，请参阅 将 Lua 脚本添加到组件实体.

在以下示例中，实体的不透明度在 “5” 秒内线性补间为 “0.5”。

local AnimateUiEntity =
{
	Properties =
	{
		ToAnimate = {default = EntityId()},
	},
}
function AnimateUiEntity:OnActivate()
	self.tickBusHandler = TickBus.Connect(self)
	self.ScriptedEntityTweener = require("Scripts.ScriptedEntityTweener.ScriptedEntityTweener")
end

function AnimateUiEntity:OnTick(deltaTime, timePoint)
	self.tickBusHandler:Disconnect()
	self.ScriptedEntityTweener:StartAnimation
	{
		id = self.Properties.ToAnimate,
		duration = 5.0,
		["opacity"] = 0.5,
	}
end
function AnimateUiEntity:OnDeactivate()
	self.ScriptedEntityTweener:OnDeactivate()
end
return AnimateUiEntity

以下示例显示了具有所有默认参数的完整调用。在此示例中，实体duration为 5 秒内移动到代码中指示的 ["x"] 和 ["y"]位置。

self.ScriptedEntityTweener:StartAnimation
	{
		id = self.Properties.ToAnimate,
		duration = 5.0,
		["x"] = 150, ["y"] = 200,
		timeIntoTween = 0, -- Start tween some seconds in
		easeMethod = ScriptedEntityTweenerEasingMethod_Linear,
		easeType = ScriptedEntityTweenerEasingType_In,
		delay = 0,
		timesToPlay = 1,
		isFrom = false,
		isPlayingBackward = false,
		uuid = Uuid.Create(),
		--onComplete = function() Debug.Log("Called when this animation is done") end
		--onUpdate = function(currentValue, currentProgressPercent) Debug.Log("Called when this animation updates") end
		--onLoop = function() Debug.Log("Looped animation") end
	}
