program Name { … }
A program is the outermost unit of Ludic source, and everything else — properties, models, handlers, functions, constants and your named state — lives inside its braces. Each program compiles to exactly one native game (or, with a module, one shared library), so a project has a single top-level program block. The name you give it is used for the built binary and for diagnostics, and by convention matches the file. When the engine boots, it runs your Start handlers once and then drives the per-frame phase loop until the game quits.
Example
program SpaceDrift {
property Position { column: int = 0, row: int = 0 }
model Player { Position }
var score: int = 0
handler Boot phase Start {
spawn Hero { Position { column: 10, row: 8 } }
}
handler DrawWorld phase Render {
Screen.clear(Color.MidnightBlue)
for (position) in query [Position, {Player}] {
Screen.fill_rectangle(x: position.column * 16, y: position.row * 16, width: 16, height: 16, color: Color.LimeGreen)
}
Screen.draw_number(x: 6, y: 4, value: score, color: Color.Gold, scale: 1)
Screen.show()
}
}
