Core Concepts

Units

Entities/objects in Enu are referred to as units, and have a base type of Unit. Currently there are Build units (voxel objects) and Bot units (the robot). There will be more in the future.

me is the unit that owns a script, and is equivalent to self/this in other environments. me was selected because it's easier for a child to type. me. can be auto-inserted when accessing properties of the unit. For example, me.speed = 10 would commonly be written as speed = 10. There are probably bugs with this behavior. Please report them.

Unit will be renamed to Thing at some point in the future.

Prototypes

Enu uses a prototype based object system for units. To allow a unit to be a prototype, you give it a name:

name ghost

Then create a new instance in a different script with .new:

var ghost2 = ghost.new

You can also provide parameters, which can be overridden when creating a new instance:

name ghost(color = white, speed = 5, spookiness = 10)

These become properties of the unit (ie me.spookiness = 5), but can be treated like variables in the unit's script due to auto me insertion (spookiness = 200).

To create a new instance with specific property values:

var ghost2 = ghost.new(spookiness = 11)

Parameters can have a default value (spookiness = 10), which makes them optional when creating a new instance. If they should be required, or there's no reasonable default value to use, specify a type (spookiness: int) instead, or omit both the value and the type, which will make the type auto.

speed, color, and global can always be passed to a new instance, even if the prototype name doesn't include them.
