✔️ FIXED BUG: No Wheel Control at Tile Edges
Posted: 2024-Mar-19, 19:21
Not very important for TAW, since all runways are always in the middle of a tile. But very important for Ace Combat with small tiles:
If you roll over the edge between two tiles, strange things happen. The plane might slow down drastically. You may lose steering. Control surfaces start moving.
It is extremely apparant on this aircraft carrier in AC3, which is placed in-between four tiles:
Looks like the physics engine tests every wheel four times: Once for each tile. (This is correct, as the plane overlaps all of them and wheels may come into contact with either.)
One tile collides with the wheel, and forces are computed correctly. But the other three do not, and the wheels reset to “not touching terrain”. When the FCS checks wheel load, it finds that no wheel touches the ground, so it assumes the plane is airborne.
Wheels should not reset to “not touching terrain” when a collision test fails, they should do so when all collision tests fail!
