bertie Booster - I just tried the Bullet behavior and came up with a snag. The sprites don't always move down 100px exactly. They always end up a few of pixels up or down instead of the exact 100px. Oherwise, this seems to be a nice, easy method too. Thanks for pointing me in this direction. But for my particular problem, the positions of the pixels have to be exact. Not sure how to get there.

[quote:2kuyx7ua]That will also work.OP, set your "Overlapping at Offset" condition's 100 to 25.It works,and will have a nice effect.

Changing to 25 from 100 does work beautifully. Could you explain how you came to that particular number and would it work if the distance of the sprites change?

And thanks to everyone who has taken an interest. I am trying out all the methods mentioned, even though Doc Ai's solution is easier for a newbie like me.

Thanks for your reply. So quick too.

I tried your suggestion and made this capx.

But it doesn't work properly. The sprite now moves slowly and smoothly but it doesn't always stop in the right place. I am sure I am missing something but can't figure out what.

The file is below if you'd like to check it out. Thanks.

I am a newbie and so this might be a very obvious question.

I want a sprite to move down 50 pixels when a certain condition is met. I have tried using "move at an angle" but it's too abrupt. I want to be able to see the movement. I have tried to use "8 movement" but didn't get anywhere. Using "8 movement", the sprite starts moving down and keeps moving. It doesn't stop after 50 px. So what do I do?

Thanks.
