Critterding

Critterding is an open source and "petry dish"-universe in C++ and OpenGL that demonstrates simple artificial intelligence by evolution.

Here's how the program works: it sets up a 25x25 world with 500 food units
and keeps throwing in critters with randomly generated brains.

Critters are informed by sensors:
- if they are standing over food
- if they are able to procreate
- if they are able to fire a bullet
- if they are carrying food
- if they are carrying corpse
- about their energy state
- about their age
- what the world looks like (RGBA vision)

Critters can make use of the following motor neurons (actions):
- move forward
- move backwards
- strafe left
- strafe right
- rotate left
- rotate right
- eat
- fire
- procreate
- pick up / drop

What is new in this release:

• This version adds wavefront obj maps, textures, normal mapping, and critter cameras. Windows executables are available again.

What is new in version 1.0 Beta 12.1:

• some fixes and cleanups
• catch segfault when using headless without critter_raycastvision

What is new in version 1.0 Beta 12:

• critter selection and actions (kill, duplicate)
• new panels: neural net brainviewer, hud, species list
• touchingcritter brain input fix
• profile saves to ~/critterding/save/(profile)/(profile).pro
• toggle rendering of gui and scene (keys h & r)
• font switch to DejaVuSans
• an icon thanks to jrabbit
• new options:
• --roundworld: a round planet
• --benchmark: times a scene of 10000 frames
• --headless: console mode
• --startseed: seed for the random number generator
• --killhalf_incrworldsizeX/Y: option to increase worldsize when killhalf triggers
• --killhalf_decrmaxlifetimepct: option to decrease critter maxlifetime when killhalf triggers
• --critter_raycastvision: raycast vision for critters
• --threads, number of threads, making openmp (comes with gcc4.2+) a requirement
• build system:
• if available, build against system ftgl (pass --disable-system-ftgl to use internal) make install
• many fixes, cleanups & changes

What is new in version 1.0 Beta 11:

• This release has an improved graphical user interface with new settings panels, an exit panel, and a critters vs food graph.
• It adds a few more body mutations.
• There are numerous other improvements, fixes, and cleanups.

What is new in version 1.0 Beta 10:

• This release features a game changing rewrite, and now incorporates Bullet Physics, SDL, mouse look, and phenotypes.

What is new in version 1.0 Beta 9:

• Herbivores and carnivores now have distinct skincolor.
• Bullets no longer shoot through walls.
• Text is rendered with fglx.
• Synaptic plasticity of brains was improved.
• Many fixes and cleanups were made.

What is new in version Beta 8:

• new: custom settings profiles, critter autosaving, exit-if-empty
• corpses and carrying are disabled at default
• various fixes and cleanups
