Why can't i make a enemy jump?

I doubt Construct2 is the problem, as I've shown you those events and actions work..

It's all the events I have in the above download and it has the expected result..

Your issue must lie elsewhere in your event-sheet..

Sharing your capx or making a screenshot of your events, might make it a lot easier to find out what's wrong..

But ofcourse you can try another game-making program as well, if you can't get the hang of this one..
