Alright, seeing as I'm not in you're mind, and can't see the scene as you'd have it. You should go into the Database and to the animation tabs and look at ALL the animations. I only say that because even though it isn't titled Explosion, it may look like what you want. Haha, I rarely use things that are Titled or closely titled to what I want to use. I also suggest to use the Event Smoke and set it to stopped animation. Then have the BOOM! But that's just me, I don't know how your scene works. To do the flying thing, I have two ways. One easy and one hard.
Easy: Use the Jump feature. It's in the move command, look on the grid of the map and find where you want themt o fly to. If you need help ask (Basics, if you minus a number the character will go down the scale rather it be the X or the Y cor. if you add, then it goes up. Add something to the Y, they'll go up the map. If you minus to the X, then they'll move left)
Hard: Use the show picture command (First get pictures files of the Characters or what you want to use). Now the reason why this is hard, it's not because it is hard, it's easy. It's because you have to know how to use the show Picture command. So if you don't you'd have to learn. But this is how I would do it, because I could have all the control of every part of it. If you're really good, you could do the whole scene this way and really make it look like the Stove blow up and such......and things are on fire....I've seen some really cool things done this way. It also is hard, because it takes some creativity and some hard work. I my self don't see that as hard, but eh.
If you're new or if you just something quick go for the easy. I hope I helped and again ask and I'll go into more detail.
