method
Screen.camera
Screen.camera(x, y)
Sets a camera offset applied to every draw: a world point (wx, wy) lands on screen at (wx - x, wy - y). Move it to scroll the world under a fixed viewport. The camera moves everything drawn, so reset it to (0, 0) before drawing a fixed HUD. Same control as Camera.set. Deterministic.
Example
program Demo {
property Position { x: int = 0, y: int = 0 }
model Player { Position }
handler DrawWorld phase Render {
Screen.camera(Position.x - 160, Position.y - 120) # centre on the player
Screen.fill_rectangle(x: 0, y: 0, width: 16, height: 16, color: Color.Red)
Screen.camera(0, 0) # HUD in screen space
Screen.draw_text(x: 4, y: 4, text: "SCORE", color: Color.White, scale: 1)
Screen.show()
}
