use particles, and give them a cool looking smoke puff. then build from there,anyway, making explosions is a pretty advanced technique, start playing around with making smoke and rocket trails first

Use a program like Photoshop or Paint.net or GIMP. Something that you can export .pngs with transparency.

Make a white O (not a solid circle, but like the letter O with a hole in the middle) on a transparent background and blur it a bunch.

Export the blurry O as a .png with transparency.

Then import it into a sprite in Construct. Add the Magnify effect.

When you create your explosion, make a scaled-down O sprite at the center, then scale it up over time so it expands. The magnify effect will make a warpy circle at your explosion site. Fade it out as it gets bigger as well. That should do the trick.

I've made some pretty cool shock waves before:

1)Make a sprite
2)In the picture editor, make the size of the drawing about the size of the screen, but square. (so like 500x500 or something, I guess it depends, though its not that important.)
3)Draw a huge white circle over the whole thing.
4)Get out the brush tool and type in the size thing about 20 less than the size of your entire sprite, set the hardness to 0 (or something small), and choose the colour opacity 0.
5)Once you've set up the brush draw a dot in the middle (you can see the mouse coordinates at the bottom)
6)Press 5 on the numpad to centre the hotspot.
7)Sprite is done, apply a magnify effect
8)Make some event create it, and add to this, set sprite width to 1 set sprite height to 1
9)Add event: always -> set sprite height to .height+1000*timedelta
set sprite width to .height
set opacity to .opacity-100*timedelta
10) add event: sprite.opacity < 1 -> destroy sprite
11)Fiddle about with the constants until it behaves how you want

I can make an example later if you want.

Lens would be a good effect to use as well.

I made an interesting blastwave once using heightmap also.

I tried Lens with my method and the entire area of the sprite becomes a lens instead of just the white parts.

Maybe lens is meant to be used with grayscale/no transparency instead of just alpha channel? I don't know, I can't test it right now.

Lens is used to both magnify and zoom out regions of the background. 50% grey corresponds to no effect, white is magnify, and black is zoom out (or possibly the other way round...)

Generally, Magnify is more useful.

Hey I was right :P

Except I didn't know about the anti-magnify part. That's actually kind of cool.

Effects are one area of Construct I really haven't explored yet, I really should take a look at all those.

Yeah Lens and alpha, not so much. I used it for the zoom out part of it, which I wanted for a certain effect.
