POC for an anti-ballistics. This should be called instead of the raycast iteration unturned does. Generates only the final raycast step.

Unturned Anti-Ballistics POC

public static RaycastInfo ShootStraight()
		{
			//do full flat raycast as if the server had no ballistics
			UseableGun gun = OptimizationVariables.MainPlayer.equipment.useable as UseableGun;
			RaycastInfo r = DamageTool.raycast(
					new Ray(OptimizationVariables.MainPlayer.transform.position,
						OptimizationVariables.MainPlayer.transform.forward), gun.equippedGunAsset.range,
					RayMasks.DAMAGE_CLIENT, OptimizationVariables.MainPlayer);
			if (r.IsRaycastInvalid())
				return null;
			//determine how many ballistic steps are required for the whole travel, except for the final one
			int requiredSteps = (int) Math.Round(r.distance / gun.equippedGunAsset.ballisticSteps) - 1;
			//select final step, original, absolute position: multiply the forward direction to account for the earlier steps and add in the originals player position
			Vector3 targetFinalStepOrigin = OptimizationVariables.MainPlayer.transform.position + r.direction * requiredSteps;
			//raycast from this final step to the target object which is bound to still exist, 
			RaycastInfo finalRaycast = DamageTool.raycast(
				new Ray(targetFinalStepOrigin,
					r.direction), 40f, //smaller just to optimise rather than using the whole distance, probably can be minimised further
				RayMasks.DAMAGE_CLIENT, OptimizationVariables.MainPlayer);
			return finalRaycast;
