Physics Problem: Player "floats" at low speeds #123

Closed NickolausDS closed 9 years ago

NickolausDS commented 9 years ago

When the player launches, or flies at low speeds, they begin to "float" in place -- meaning they move very slowly with an unrealistic decent rate. The physics begins to work if the player pitches forward and gains speed.

Theory 1: At low speeds, the gliding mechanic forces the object to fly level. Forcing them to fly level means as they descend their angle of attack is between 30 - 90 degrees, creating very high drag and causing them to float.

Edit: Confirmed Theory 1: Drag coefficient reaches a number of 7 or 8 at high angles of attack, causing extreme drag.

Theory 2: The lift coefficient isn't being properly calculated for extreme angles of attack, and doesn't decrease as the airfoil reaches stall speed.

Fixed: First, the drag coefficient has been turned down for various angles of attack. Second, gliding is now partially based on angle of attack to automatically "restart" the wing after stalls.
