After a short break [due to some ongoing health issues] here is another step-by-step-tutorial into the wild side of vectors - well not really wild but a little explosive this time around. I was asked to write a tutorial on explosions, which didn't seem that hard until I started... It's become common practice to use particle effect for most ingame explosions, so doing an explosion by hand was a bit of a challenge.
It's a fairly generic, cartoon style explosion - quick and easy to create [and animate - by scaling the elements and fading to either light or dark as the explosion progresses].
This is still a very cartoony look. Let's try something a little less 'flat' and add some volume to the explosions.
This explosion is a bit more work to animate. You would start with a smaller light centre that would grow and add more circles to it that go darker as they reach the outside. The flash in the centre is just that - a flash - don't keep it on for too long or it will look more like a light source than an explosion. As this explosion dies down the dark circles would go grey and black, shrink and fall apart [either by imploding or falling to the ground].
I hope you enjoy this one as much as I do... It's just too much fun to blow things up in style and I have to stop myself now and try and catch up with work (before writing the next tutorial that's already playing havoc with my imagination).
