Algodoo

Good old UFO with as much burning death weapons strapped on as I
could.

Mouse movement , use keys W, A, S, D and Q to activate the weapons.
--- --- ---
W: Heat ray
Burns everything to a crisp.
Burning slowly lowers an object's density and chars it. At a low
enough density, the object is obliterated without a trace.

Collides with B so if you want to add objects to this scene make
them collide with B.

A: Tractor beam
Pick up and throw objects. Unlike my previous UFO, it suspends the
object instead of abducting it.

S: Firebombs
Rapidfire firebombs that blows stuff up (about 20 bombs /second),
triggered on contact.

Burning slowly lowers an object's density and chars it. At a low
enough density, the object is obliterated without a trace. Firebombing
chars and destroys objects faster than the heat ray.

D: Flamethrower
Very laggy flamethrower of doom. Unlike the firebombs, it relies on
gravity to fall to the ground. Contact with objects char and destroy them,
and spew burning embers thet stick to objects and fly around.

I personally like the flamethrower. Before I toned it down it woild add
up to 2000 updating and moving geometries, and while it looked really
cool I had to lower teh amount of embers spewed. Still looks great though.

Burning slowly lowers an object's density and chars it. At a low

Q: Black hole nuke
One use. Creates a black hole at the UFO's position that absorbs matter
for 2 seconds, before releasing a massive explosion that sucks in and
annihilates everything.

Test subjects provided:
Objects of different densities
A building
2 formations of planes with different speed

Ground blinks sometimes when shot because the weapons char the
ground as well, and since I don't know how to stop them from doing so
I just made the ground revert back to its original color every tick.
