- enchanted arrow explode upon hit the water plane
- non enchanted arrow disappear (or more accurately, they hit nothingness)
- enchanted arrow shot underwater explode immediately
- non enchanted arrow disappear immediately
Also, solve a bug that occured previously and could theoritically still happens where we use the last tested collision position for instead of the last registered hit:
Use the hit position as saved inside Projectile::hit() instead of the last position saved inside the callback.
If a projectile collides with several objects (bottom of the sea and water surface for instance), the last collision tested won't necessarily be the impact position as we have no control over the order in which the tests are performed.
imprecision issue with projectile collision detection.
Simplify the mechanics: manage hits in one spot.
Give magic projectiles a collision shape similar in size to their visible
model.
Rename the 2 convex result callback to clearly state their purpose.
