GTween setPaused gotcha ;)

moopf

Been banging my head against a brick wall this morning for an hour or so trying to work out why a GTween wouldn't respect setPaused straight after creation - the reason I'm doing this is to load back in a game state if the app was exited whilst you were in the middle of a game. Anyway, after trying to change code in GTween I decided to RTFM (well there is no manual, but I looked through the class for hints). There's an option that you can set called autoPlay - set this to false to stop the tween from automatically running, e.g:

<pre> self.tween = GTween.new(self.image, 20, {scaleX=0}, {autoPlay=false})

Anyway, just thought I'd post it here in case other people encounter the same problem.

Also for those interested and to extend that discovery, autoPlay = false is the way to chain tweens.

Here is the correct way to chain tweens:

local tween1 = GTween.new(sprite, 1, {x = 240}, {}) local tween2 = GTween.new(sprite, 1, {y = 100}, {autoPlay = false}) local tween3 = GTween.new(sprite, 1, {alpha = 0}, {autoPlay = false}) tween1.nextTween = tween2 tween2.nextTween = tween3

Also this is same:

local tween3 = GTween.new(sprite, 1, {alpha = 0}, {autoPlay = false}) local tween2 = GTween.new(sprite, 1, {y = 100}, {autoPlay = false, nextTween = tween3}) local tween1 = GTween.new(sprite, 1, {x = 240}, {nextTween = tween2})
