Raptor

Raptor is a lightweight Windows application built specifically for helping users simulate an Artificial Life system where you can add various entities, examine them, and watch their evolution.
It sports a clean and straightforward layout that allows you to perform most operations with just a few clicks.
Raptor gives you the possibility to create a new world or load an existing project, prevent overpopulation, enable or disable sound effects and background music, and apply blurring effects.
Other important options worth mentioning enable you to select a background image for your world (JPEG, BMP) or create a slideshow with the photos stored in the specified directory.
What’s more, you can run or pause the evolution process, and view information about the total number of creatures and energy level, as well as gather details (type, energy, life) about each creature by simply hovering the mouse cursor on the desired particle.
Raptor also features a built-in editor which lets you design new creatures by specifying the ID, name, type, minimum and maximum energy level, maximum life time, and color.
The application comes packed with several preset creatures that can be inserted into the system, and lets you save the generated world to a file.
All things considered, Raptor provides useful features for helping you simulate various living organisms, ecological systems, or other entities. Thanks to its intuitive interface, it is suitable for beginners and professionals alike.
