Destroying opponents by... bouncing on them?

Here's the example:

I didn't realize your problem was with AND/OR conditions, so you may not need this anymore. But it might still help.

I added another example using the Y position comparisons rather than invisible detectors.

Someone said they could never get it to work, so I wanted to prove that it IS possible.

I didn't read many of the comments here, so apologies if someone else has beaten me to it, but I've often found issues with using a foot detector.

The best way I found is to not use a foot detector. Instead, check on collision whether the player's Y force is upward or downward. So my character has his Y speed in an alterable value, for instance:

Player collides with badguy
+ Y Speed > 0 (he's falling)
--- Bad guy gets hurt
--- Player bounces

Player collides with badguy
+ Y Speed <= 0 (he's stopped or jumping upwards)
--- Player gets hurt
--- Player bounces

So for me, the issue is whether he's going downwards or not which determines whether the collision is 'jumping on the bad guy' or 'being pwned by the bad guy'.

I found it works pretty well, I've had no problems with it to date.
