問題の詳細/Issue Details

Steps:

1. Equip any Gunlance and proceed to a large monster hunt. We’ll use a Normal Shell Type gunlance vs a Zinogre for the purpose of reproducing the issue, but this issue occurs for any monster. Use a Gunlance that is overpowered against a monster of a lower grade (e.g. Grade 9.5 vs 7-star Zinogre) with Artillery Lv.3 and Partbreaker Lv.3.
2. At the start of the hunt, aim at the Zinogre’s right foreleg and perform a Rising Slash, Overhead Smash, then Burst Fire to break the Zinogre’s forelegs.
3. As the Zinogre rolls the hunter’s right from the broken body part, quickly move towards the Zinogre’s tail from its back (evade to your left).
4. While you’re right next to the tail (within hammer side swing striking distance), tap to perform a quick reload to reload your empty shell magazine, then aim at the middle of the tail and tap three times to perform two normal shelling and then perform a wyrmstake cannon attack.
5. Observe that the wyrmstake cannon hits the tail just as the Zinogre recovers from writhing on the ground, and observe that the wyrmstake is stuck on its right hindleg instead of on the tail.

Expected:

1. The right hindleg was nowhere near the point of impact of where the gunlance hit the monster when the wyrmstake staking hit occurred. Therefore, it should not stick to anywhere else but the point of impact of where the wyrmstake ammo hit the monster’s body.

Notes:

• This applies to any monster.
• I’m referring specifically to the hit that lodges the wyrmstake ammo on the monster, not the initial gunlance jab.
• This occurs most easily when you’re performing wyrmstake attack at very close range, and the monster has surface areas of other body parts near to where the point of wyrmstake ammo impact is at the point of sticking.
• It seems to me that the game chooses the “nearest body surface” when determining where to stick the wyrmstake ammo in when the point of impact clips into the monster’s body, but instead of choosing the closest distance between the point of impact and the hunter’s body (which makes sense, since the gunlance is held in the hunter’s hand and jabs straight into the monster, therefore the wyrmstake must lodge somewhere long the line of the gunlance, which is a straight line from the hunter to the point of impact), the game chooses the nearest surface area on the monster, and that can sometimes cause the wyrmstake ammo to lodge in unexpected players. Often, I hit the tail or the head with the wyrmstake attack, and yet the wyrmstake lodges itself at the butt, the hindleg, or the neck of the monster, or even the wing of Diablos when I wyrmstake the head from the side while standing between the wing and the head. It is very strange.
• If the gunlance’s muzzle did not clip into the monster at the point of firing the wyrmstake, it will simply stick to any body part that the wyrmstake ammo touches in a relatively forward cone of fire, which makes sense since you’re technically firing an explosive that’s designed to eject itself from the gunlance but not meant to shoot forward like a bowgun projectile, but this also means that the wyrmstaking lodging logic behaves unexpectedly and negatively when the wyrmstake is fired while the gunlance muzzle clips into the monster’s body.
• This makes the use of wyrmstake for the purpose of breaking specific body part unpredictable, especially when I’m trying to cut tails with it. When it functions as expected, it is actually very good at breaking specific body parts. But right now it’s unpredictable, and I often end up breaking the wrong body part or damaging an already broken body part instead of hitting an unbroken body part.

その他の情報/Other Information

Issue persisted since the release of gunlance. Nothing helps other than standing at a distance so that the gunlance’s muzzle doesn’t clip into the monster at the time of firing the wyrmstake, which is a difficult thing to do, given the lack of precise movement control in this game.
