The How And Why

Third Party Libraries

This engine uses a few third party libraries which solve a great deal of problems:

• 30log for class definition
• STI for the tiled maps
• Hardon Collider for the collision handling
• anim8 for animations

Thanks to all the creators of these!

Characters

Each object defined in the 'character' layer of the map must have a character definition in the 'characters' folder. The file is named like the name of the object. For example an object named matty has a file 'characters/matty.lua'.

In this file all the other properties are defined.

And to clarify: a player is just a character with relevant keys attached to it.

Controllers

Defines the movement of a character. Each character has its own instance. It must implement at least the following functions:

• sendKey(key)
  • send a keypress to the controller which then decides if it takes action
• stopAnimation()
  • stops a running character animation

and the following properties:

• charinfo
  • an instance of a character file
• animation
  • the active animation

Apart from those the controller works how it sees fit.
