Ah, I see, I've checked the capx. You shouldn't be setting target every 1.0 secs (what I exactly mean is that you should set initial beforehand), it will cause the initial to be set everytime you set the target (to object current position).
It goes kinda like this:
1. Before the first tween, the object position is at 302,241.
2. At 1.0 secs, c2 called set target to absolute 100,100. Because of this call, it also set the initial of the tween to 302, 241. So, right now, the tween goes 302,241 to 100,100.
3. The tween plays, and the object is now at 100,100.
4. After another 1.0 secs, c2 called set target 100,100 (absolute) again. But now, the object is already at 100,100. So it make a tween for 100,100 to 100,100 (which does nothing).
The right way to set initial now is simply by setting the object position before you set target. If you add "Set Position to 302,241" before setting the target it will act just like setting initial.
PS: Maybe I should include a capx about it :>
