Hi, I've made a little code tutorial focusing on how to animate stuff with trig, specifically it's about animating little blob monsters like i made for my Irukandji game last year. It's up on my website here: http://www.charliesgames.com/wordpress/?p=441. The actual code, which i've tried to comment pretty well is linked from that page in a zip file. There's a video of the code running at the bottom of that page. It's fairly simple stuff, but not totally beginner friendly i guess. The code is written in Blitzmax, but should be pretty easily converted to other languages, so long as your video library supports rotating, scaling and blending images/quads. I'm really interested in hearing what people think of this, as i'd like to do some more code tutorials, but i'd rather be doing things people actually want to learn about rather than just some stuff that i like but no one else give a crap about. Let me know what you think! Cheers Charlie |

Very interesting and nice looking. Did you make some sort of editor to make the monsters in?
This would also go really well in some sort of system where the creatures change based on evolution. Great job!

No editor, just trig. I'm sure it could be adapted to allow the creatures you make to evolve over time or depending on certain parameters. At present you can already change the number of body segments, but you could certainly make changes to allow a greater variety of shapes for the little fins etc. Take a look at the code! Cheers Charlie |

Hey this looks amazing in action. Taught me some new standard things in BlitzMax, too. Didn't know you could so easily make things "glow".

Glow's easy! It's what you do with it that counts!
Glad you liked it!
Cheers

This looks very interesting but... is there no way to view it without installing BlitzMax?

Wait, Irukandji was made with BlitzMax?
I love you.

Irukandji does indeed look stunning, but unfortunately I still can't beat the first level so have never gotten to see most of it. I tried so hard to beat that damn crab.    I'm still amazed it's all done using only one sprite and a shit load of trig. Shoot it's claws off first, then go nuts with your missiles! <-how to beat the crab! |

Believe me I tried that, I tried that a lot. I can destroy the claws, but it always then fires a wall of bullets that I can't escape from. I think my bullet hell skills are a little lacking.

If it helps, only the little dot at the front of your ship is a collision zone, and the little dot in the center of the bullets too!
Cheers

OddBall:What I usually do is wait until you can hit the crab,then nuke it with my special then just shoot it till it dies.
Charlie: Very nice tutorial but I can't help but wonder how you handled collision checking.

As i recall, i just used rect collisions. I think i just placed rects in key places on each monster, i.e. one for each of the crabs claws, and a larger one for the body. Cheers Charlie |

Cheers Charlie Ah that makes sense, also do you optimize your collisions i.e quad trees or regions or is it just brute force checks? |
