Textual event script writing and compiling about editor HOT 2 OPEN

I hacked now together some basic javascript for this and bound it to C++ via QuickJS. Highly experimental.

With the following "event code" which is valid Javascript

$msg("Javascript!!1");

$showpic("Punkt").id(1).x(0).y(180);

for (let i = 0; i <= 360; ++i) {
	$movepic().id(1).x(i / 360 * 320).y(Math.sin(to_rad(i)) * 120 + 120);
	$wait(0);
}

Generated event code:

I generate the following event which shows a Sinus curve: (sorry for the flicker)

from editor.

I also had this in my mind.

My idea would be using a Javascript engine that is used as a macro-language to emit event code. The Editor executes it to generate the event commands.

Semantic (reserved variable prefixes):

• $ Event code (Appears as event command)
• _ constant stuff (evaluated during compile time)

Example:

for (let i = 0; i < 3; ++i) {
  $V(i, '=', i*2);
}
$C("---");
for (let i = 1; i < 3; ++i) {
  $V(i, '+', $V[i]);
$C("+++");
let val = 100;
$V(5, '=', 100 + _db.monsters[2].attack); // OK. DB is Constant expression
$V(5, '=', $game.party.actor[1].level); // OK. Fetches party actor 1 level at runtime

This is evaluated while typing. Functions prefixed with $ appear in event code.
This would emit:

@CtrlVariable(V1 = 0)
@CtrlVariable(V1 = 2)
@CtrlVariable(V1 = 4)
@Comment(---)
@CtrlVariable(V1 + V1)
@CtrlVariable(V2 + V2)
@Comment(+++)
@CtrlVariable(V5 = 140) <- Evaluated at compile time, monster attack in DB was 40
@CtrlVariable(V1 = Actor 1 Level)

Errors:

$V(5, '=', 100 + $game.party.actor[1].level); // Error $game is not constant
let val = $V[3] // Error $V is not a constant

from editor.
