Description
I finally uploaded something in Flash!Well... this was a blast to make. I've wanted to do this ever since I first started, but never figured it out. Well, here it is.
The little evil spark plugs wander around, avoiding collisions. Lots of math involved.
This engine will work really well for racing games, as you can see by that racetrack thing in the middle...
Ok. Controls. Click to spawn little bug thingies, and hit the spacebar to remove them all. That's it!
Yes, I will give you the code if you note me. It's heavily commented, although slightly mispelled, in English, cause that's the only language I know. Actionscript 3, with flash CS4 or above. I might make a pure Actionscript version, like Flash Builder or FlashDevelop, but... too lazy right now.
[EDIT]
I added a counter, so you can see how many thingies there are.
[END EDIT]
Tools: Flash CS5.5
Work Time: about 2 hours...
Let the continuous commenting commence!

Sometimes, clicking causes the spawn thing to fly away (out of the screen)
I guess this could be interesting:

Thanks for the link, looks interesting.
Yes... if the thingumabob backs into something, it immediatly accelerates... unfortunately, it accelerates backwards, farther into the object, going faster and faster until... it shoots off the screen.
I'm sure there's a way to fix it, but... too lazy.

You should include a counter for the amount of spark plugs on the field
I clicked until it started going really slow; but I couldn't count all the plugs :<

Done!
I can get to 50, then it starts to lag.

Glad you like it!
Here's the source code: [link]
If you have any questions... just ask. Enjoy!

woah, thank you very much for it

np. I really just did it to figure out how, so why keep it to myself?

It's a neat take on collision avoidance. I assume it doesn't predict anything but is completely responsive. When a certain distance from the wall turn based on the angle it would go into the collision at.
What about extremely tight spaces and hitting the wall straight on? Are there things in place to account for that?
👍: 0 ⏩: 1
Nope, completely responsive.
Hitting the wall straight on triggers a reduction of speed. The closer to straight on and the harder it hits, the more the speed is reduced, which is why it bounces backwards.
Tight spaces... not so much. I wasn't sure how to solve that problem...

A flash program... not exactly art.

Okay, I have no idea what that means.
