Responding To User Interaction
To respond to key press events use the “when key” event handler:
ship is a gemini when key Left is pressed do ship.move left 1 in 0.1 seconds end do
This will move the player’s ship 1 meter to the left whenever the left arrow key was pressed.
You can add as many event handlers as you like.
ship is a gemini when key R is pressed do ship.turn right 30 in 0.1 seconds end do when key L is pressed do ship.turn left 30 in 0.1 seconds end do
You can also respond to mouse click events:
ship is a gemini when mouse left is pressed do ship.turn left 45 in 1 second end do
