Pathfinding doesnt want to drop from "high" places

Help and Feedback Scripting Support
#1

I’ve been trying to script a stupid pathfinding system for like 10 hours now, and I’m getting somewhat close.

Right now I’m using the script from the Character Pathfinding documentation, and I’m having problems making the NPC pathfinding go down from stuff

local char = script.Parent;
local root = char:WaitForChild("HumanoidRootPart");
local torso = char:WaitForChild("Torso");

local hum = char:WaitForChild("Humanoid");
local statusEffects = hum:WaitForChild("StatusEffects");
local health = hum:WaitForChild("PlayerHealth");
local armor = hum:WaitForChild("PlayerArmor");
local state = hum:WaitForChild("PlayerState");

local npcName = char.Name;
local startingPos = root.Position;

local jumpTick = tick();
local wanderTick = 0;

local pathfindingService = game:GetService("PathfindingService");
local runService = game:GetService("RunService");

local getSortedTargets = require(game.ReplicatedStorage.Functions.NPCs.Functions.GetSortedTargets);
local runAdjustors = require(game.ReplicatedStorage.Functions.Misc.RunAdjustors);
local getIgnores = require(game.ReplicatedStorage.Functions.Misc.GetRaycastIgnores);

local loadout = {	
	alive = false;
	stunned = false;

	target = nil;
	lastSeenTargetPosition = nil;
	
	range = 0;
	damage = 0;
	walkspeed = 0;
	jumppower = 0;
};

local charSize = char:GetExtentsSize();

local pathParams = {
	WaypointSpacing = math.huge;

	AgentRadius = (charSize.X+charSize.Z)/4;
	AgentHeight = charSize.Y;
	AgentCanJump = true;

I think I’ve looked through like 30 different threads on pathfinding shenanigans, but I can’t find anything on this issue.

Can anyone tell me what might be wrong, or point me to some direction?

#2

I tried offseting the Y axis of the destination by -2, thinking the path finding is trying to reach something in mid air, but that didn’t seem to work
