| **Q:** Why do Cannons not shoot at the top of waves/visible creeper and instead aim at the terrain. \\ | **Q:** Why do Cannons not shoot at the top of waves/visible creeper and instead aim at the terrain. \\ **A:** Cannons fire in a straight Line-of-Sight (Los) from the barrel to the terrain, limited by distance. There's no artificial rule about not being able to shoot higher. It just has to be able to 'see' the terrain it is firing at. So it can shoot up at a higher ledge, but it can't shoot at a terrain cell that is inland on higher terrain (since there is not line of sight to that cell) |

| From a game play perspective, firing part of the way up (into a wave, or at the top of a wave) has two impacts; It can miss more than you realize (because the creeper gets lowered before the shell arrives), and it's more computationally intense to calculate how high to shoot (or to try to predict what the height should be at some point in the future). | From a game play perspective, firing part of the way up (into a wave, or at the top of a wave) has two impacts; It can miss more than you realize (because the creeper gets lowered before the shell arrives), and it's more computationally intense to calculate how high to shoot (or to try to predict what the height should be at some point in the future). |

| **Q:** How do target acquisition work for cannons (and sprayers)? \\ | **Q:** How do target acquisition work for cannons (and sprayers)? \\ **A:** Cannons in CW4 don't have have any other rule than "line of sight and max range". So if there is a slope or a ledge, a cannon will shoot up at it. Normally, a cannon barrel sits just slightly lower than "1" off of the terrain it is sitting on. So it can't see on top of adjacent terrain that is 1 level higher than it is. It can see the edge, though. Nearby hills might have edges that hold creeper and the cannons can shoot at them. The old rules in CW3 were based not on LOS but on higher or lower. In CW3, it's just straight line LOS. Note that it is the map vertices that are evaluated. |

| The reason cannons can't just shoot at all lower terrain in range is... they'd be shooting through the terrain. | The reason cannons can't just shoot at all lower terrain in range is... they'd be shooting through the terrain. |

| | **Q:** How do target acquisition work for mortars? \\ **A:** Mortars use a simplified parabolic calculation for line of sight. It's simplified to a triangle. So it's two straight LOS calculations. For every point in range they check for LOS to a midpoint (at a height) and from the midpoint to the target. |
