I've been struggling for hours to try to get the player character (plane) with a bullet behaviour to move towards a target. But it did not work properly: the angle was much to shallow, and it would miss the target by a wide margin.
And it worked consistently with a smaller demo I tested the behaviour in.
After all the debugging, testing, etc, it suddenly struck me: that particular game level is 48000px wide, and the target and player character were on different layers, with different parallax settings.
I knew this was going to be a bad day to work on the game when I stepped out of bed this morning. I should have enjoyed the sunny Easter weather here in Vancouver.
Moral of the story: do not try to use the set bullet angle of motion on two different parallax layers. It will not work as expected.
Sigh. Happy Easter, everyone.
