It's a sailing game! The sail boat is simulated using lift and drag equations, with made up coefficient, I'm surprised how well it turns out to simulate sailing. Made for the olc::BeatTheBordem Game Jam 2020, with the theme of outdoors.
Go 50 m upwind, with the wind coming from the right of the screen.
- UP: Let the sail out
- DOWN: Pull the sail in
- LEFT: Move the rudder to the left, to go left.
- RIGHT: Move the rudder to the right, to go right.
- NUMBER 1 & 2 will zoom in and out.
- SPACE: Advance 1 frame at a time (pauses too).
- TAB: Pause/unpause.
- ENTER: Show Debugging information.
- R: Reset the game.
- When paused, WASD will move the camera around
The lift and drag of the sail & keel are accounted for, however not in the moments. The rudder does not produced any drag, but it does produce a moment, otherwise it wouldn't work. The fidelity and realism would be improved if the sail did produce it's own moment, and it would make starting off easier. Ha! Normal and Axial force coefficients of all foils are just made up completely by me. Uses First order time stepping. Things get really bad in on a slow computer at the minimum tick rate of 200Hz when you're really speeding. The sail is procedurally animating according to the lift and drag on the sail, but the shape of it is art, not science.
This uses nanosvg,h and olcPixelGameEngine.h
(I don't know how to do this properly. What's Javid's and the OLC community is theirs, and I would like to distrubte this software under the OLC-3 license, however it apples.)
