Some ideas for the scripting engine for Doodads inside your level.
The script will be an "attached file" in the Doodad format as a special file named "index.js" as the entry point.
Each Doodad will have its index.js script loaded into an isolated JS
environment where it can't access any data about other Doodads or anything
user specific. The main() function is called so the Doodad script can
set itself up.
The main() function should:
The script interacts with the Doodle application through an API broker object (a Go surface area of functions).
type API interface {
// "Self" functions.
SetFrame(frame int) // Set the currently visible frame in this Doodad.
MoveTo(render.Point)
// Game functions.k
EndLevel() // Exit the current level with a victory
/************************************

// When we become visible on screen or disappear off the screen.
OnVisible()
OnHidden()
// OnEnter: the other Doodad has ENTIRELY entered our box. Or if the other
// doodad is bigger, they have ENTIRELY enveloped ours.
OnEnter(func(other Doodad))
// OnCollide: when we bump into another Doodad.
OnCollide(func(other Doodad))
}
function main() {
console.log("hello world");
// Register event callbacks.
Doodle.OnEnter(onEnter);
}
// onEnter: handle when another Doodad (like the player) completely enters
// the bounding box of our Doodad. Example: a level exit.
function onEnter(other) {
}
