Start by reproducing the WG Demolisher first-ability attack with a target positioned on each side of the spike, using the linked video and the listed steps. Search the battleground and Demolisher handling code for the ability’s hit or knockback logic; done means the attack hits and knocks back a target regardless of its position around the vehicle.
