Framsticks

Hi all,

My name is Gustavo and I am trying to do some simple experiments with Framsticks. One of them implies "sensing" each individual in a population individually, and performing some actions based on the values I measure. I've observed that senseCreaturesProperty() does the job, but only at the population level, not at the creature level, and I couldn't find in the API any function/example for doing that.

Ha All,

A long time ago I came across this amusing and educational piece of software but I wonder if there is still an active community. The last post I could find was from somewhere in 2012? I would like to export scenes with POV-ray/view creatures in 3D and need to register but, right now, I'm not so sure if it's any use.

Kind regards,

Nop

Hello, I am trying to use evolution to increase my frams velocity and food finding skills.

I have adjusted the parameters so that life span and velocity are set to 1. Sadly, this does not seem to be working and the creatures lose both their speed and food finding skills, so if anyone can help I would appreciate it, thanks.

Is it still possible to register the Amiga version?
Also, would it be OK to upload the last Amiga update (1.50?) to Aminet?

Hi,

When using ODE instead of MechaStick, Framsticks throws an error "Floating point division by zero" after a few seconds of simulation. If I try to start the simulation again, it throws "ODE INTERNAL ERROR 2: invalid operation for locked space (..\..\ode\src\collision_space.cpp:729)" and the program crashes with runtime error.

When I used rr for normal plane of bending before bending muscle ([|-1:180]), in the body preview the square was rotated by 90 degrees, but in the world the muscle was bended without previous rotation in plane (rr was deleted?)

Greetings

I have Ubuntu and want to install Framsticks on it. How do I do it? I couldn't find any packages.

Is there a way to use MORE processors in one experiment at the same time?

Currently I can run 3 experiments with 100% usage on each processor but it is too complicated to make ends meet.

Thanks in advance.

Hi All,

I have been experimenting a lot with this program, and I can only say it's awesome! However, I see only "long" bots evolve with 0, 1 or 2 bifurcations. I wonder what environmental parameters could favor the evolution of creatures with higher sticks/joints ratio (without modifying fitness)? Changing gravity, terrain, muscle work hasn't worked for me so far.

With thanks,
Viktor

Hey guys,
you might already know this, but passing arguments to a function in the console doesn't seem to work.

function test(xxx){
Simulator.print(xxx);
}
test(3);

Gives this result

VMachine::getOperand - uninitialized value (unknown location)
Script::Message - undefined
