Colony provides a system and workflow that helps describe the elements needed to write 2D or 3D games. It was designed with several domain specific languages that make it easier to describe, manipulate, and use assets commonly found in game making. Such assets include (but are not limited to) textures, materials, shader programs, and scene trees of actors that are available for instantiation. Colony Engine also knows how to accept input from keyboards and most joysticks and gamepads.

The component system is a hybrid model between an ECS and an object model. The components are defined similar to CLOS defclass, and regular generic methods can be used with them. Components are added to Actors which represent game concepts like players, scenery, effects, etc. We define a component protocol invoked by Colony Engine to move your components to the next state and render them each frame.

This package holds an enhanced implementation of hooks (extension points). It works similarly to Emacs hooks with crucial improvements:

• If the compiler allows it (such as SBCL), type-checking is performed at compile-time and at run-time when adding handlers to a hook.

• On failure, multiple restarts are offered, such as disabling the offending handler or simply continuing to the next function.

• The hook handler execution order and combination can be customized.

• Anonymous functions (lambdas) can be added to hooks as handler objects. When inspecting hooks, readable names are thus exposed instead of lambda blackboxes. Handlers are compared through their names (through the mandatory name slot). A hook can not contain multiple handlers with the same name.

• A special provision is taken for “setters”, handlers that are meant to set a given place to a given values. Such handler objects can be compared and identified uniquely.
