But you have to align the arrows correctly so that the left side of the moving platform will pass over the arrows.
Guess what? This works. But this is unintuitive, I tought the arrow detector was on the middle of the platform. And maybe it would be better.
But for the platforms that don't pull characters, it's a good idea you got here.
And also a third idea: Maybe you should do two others types of pattern arrows:
-One that affect enemies and not platforms
-One that affect platforms and not enemies
The original arrow type would affect enemies AND platforms.
