    Problems pausing chained tweens

    I like chaining tweens but pausing them is problematic.

    I'm getting odd things happening, such as the character jumping and moving backwards etc...

    Here's the code:
    self.tween1 = GTween.new(self, self.travelTime, {x = self.point2}, {onComplete=turn, delay=.1})
 
self.tween2 = GTween.new(self, self.travelTime, {x = self.point1}, {autoPlay = false, onComplete=turn, delay = .1})
 
self.tween1.nextTween = self.tween2
self.tween2.nextTween = self.tween1
    And here's the bit where I'm pausing...
    	self.health = self.health - 1
	self.invincible = true
 
	if (self.tween1:isPaused() == false) then
		self.tween1:setPaused(true)
	end
 
	if (self.tween2:isPaused() == false) then
		self.tween2:setPaused(true)
	end
 
 
	self.anim:setAnimation("WORM_WRAITH_HIT")
	Timer.delayedCall(400, function()
		self.invincible = false
 
 
	if (self.tween1:isPaused() == true) then
		self.tween1:setPaused(false)
	end
 
	if (self.tween2:isPaused() == true) then
		self.tween2:setPaused(false)
	end
    I'll post the entire code in the next post...

      I have figured this out...

      The problem is you can't pause all tweens in the chain. You have to find out which tween is the current one and only pause that.

      In my case I used this in the function that runs after each tween:
      if(self.currentTween==1) then
	self.currentTween = 2
else
	self.currentTween = 1
end
      In conjunction with...
      	if(self.currentTween==1) then
		self.tween1:setPaused(true)
	else
		self.tween2:setPaused(true)
	end
      To only pause the current tween...
