Spread Value

[RickyRombo]

Start with an alterable value set to 1 or something, then:

Always
- Set Y position to Y("Enemy") + Alterable value

Enemy is overlapping backdrop
- Set Alterable value to Alterable value("Enemy")*-1
- Set Y position to Y("Enemy") + Alterable value

Is it a very good reason why to choose this method over flag toggling?

[RickyRombo]

The overlap won't trigger twice, you can stop the block by changing it to 0, its 2 events rather than 3, and that's all I got. LB might be thinking something else.

Yea, Ive had that idea that to stop the enemies would be smart. But for now, my enemies would never need it, and just so I dont mess stuff up, Ill keep the flags and start using Alterable values from now on aswell. I heard about this idea about having a stop solution not too long ago so my newest events do use alterable values. However, I dont see why Alterable values should not trigger twice while flags do. I mean, I dont know if flags do, but since you write it that way, I suppose they do?

[LB]

I never said not to use flags. I just said don't use the toggle action in this case.

[RickyRombo]

Well I added the action to make the block move back after it overlaps, so as long as the rate is constant it will never happen twice.

But flags can do this too.
