Hello, I have been trying to figure this out, but I'm stumbling a bit when I constantly feel there must be a better way to check for this and do action based on what tile around the blast hero is standing on.

We have this bomb that the hero has placed randomly on a map.
the x of this is 279 and y 280.

When it explodes I dont want it to always throw the hero x-1 y-1 and random did not work either. It is just not natural to jump into a blast.

So I wanted to know what tile the hero is actually standing on and push him/her in the natural direction of the blast.

I have drawn out this attachment while trying to find the best way to do this in eventing.

And after a while I started making this

But I needed to stop there, because I have to know if there is a better way to do this?
Have you done this before with results? Can a plugin do this? maybe I have missed a setting in conditionals but I have to know if i'm on the wrong track here thanks
