That makes sense, sure they don't want players exploiting the API. I only need X and Y, I don't need Z. Say the player's position is [X] = 0.467469, [Y] = 0.409835 and the position of the target is [X] = 0.415760, [Y] = 0.427441. At the moment, if someone were to make a combat mod, it is returning X and Y for NPCs, so it's not really protected to prevent misuse.

At the moment most of the equations I have seen for calculating the distance of a harvest node, a Crate, a barrel, an NPC seem to use just the difference of x1 and x2, then y1 and y2. HarvestMap, uses more of what I am looking for.



Standard Form: (x-a)2 + (y-b)2 = r2

HarvestMap:

dx = entry[1] - x
dy = entry[2] - y
dx * dx + dy * dy < 0.000025 ( 0.005 ^ 2 )

Say the NPC, Barrel, Crate, Sack, is at the center (a,b) and the player is at (x,y). I want to calculate that distance. Basically that is what is happening in RangeReticle. I tossed in a plethora of d("") lines to print out information. The mod successfully returned my distance from the center of the circle (a,b) in meters.

I could have been standing on the circle the same "r" distance from (a,b) and RangeReticle calculated the distance correctly. However, when I went to use GetMapPlayerPosition('reticleover') to get the position of what my reticle was on, all the values were 0, not just the Z value, but X and Y also.

Which is why I am wondering if there is another option.

Warning: Spoiler

function getTargetDistance(itemX, itemY)
 
    local multiplier = 5.0
    local theRange = 0
    -- Get details of what's under the reticle
    local targetX, targetY, targetH = GetMapPlayerPosition('reticleover')
 
    -- Get details of the player
    local selfX, selfY, selfH = GetMapPlayerPosition('player')
 
    -- Get map details
    local mapWidth, mapHeight = GetMapNumTiles()
    local mapType = GetMapType()
    local mapContentType = GetMapContentType()
 
    -- Calculate and display target range
    if targetX and targetY then
 
        local dimensionsX, dimensionsY = ZO_WorldMapContainer:GetDimensions()
 
        if mapContentType == MAP_CONTENT_NONE then
            if mapType == MAPTYPE_SUBZONE then
            elseif mapType == MAPTYPE_ZONE then
            end
        elseif mapContentType == MAP_CONTENT_AVA then
            if mapType == MAPTYPE_SUBZONE then
            elseif mapType == MAPTYPE_ZONE then
                multiplier = 12.0
            end
        elseif mapContentType == MAP_CONTENT_DUNGEON then
            if mapType == MAPTYPE_SUBZONE then
                dimensionsX, dimensionsY = ZO_WorldMapContainer1:GetDimensions()
                multiplier = 1.0
            elseif mapType == MAPTYPE_ZONE then
            end
        end
 
        if dimensionsX <= 2000 then
            previousDimensionsX = dimensionsX
        elseif previousDimensionsX <= 2000 then
            dimensionsX = previousDimensionsX
        end
            
        if dimensionsY <= 2000 then
            previousDimensionsY = dimensionsY
        elseif previousDimensionsY <= 2000 then
            dimensionsY = previousDimensionsY
        end
 
        if dimensionsX > 2000 or dimensionsY > 2000 then
            local X, Y = ZO_WorldMapContainer:GetDimensions()
            local X1, Y1 = ZO_WorldMapContainer1:GetDimensions()
            dimensionsX = math.min(X, X1)
            dimensionsY = math.min(Y, Y1)
        end
 
        local actualSelfX = selfX * dimensionsX
        local actualSelfY = selfY * dimensionsY
        local actualTargetX = itemX * dimensionsX
        local actualTargetY = itemY * dimensionsY
        local dist = math.sqrt(math.pow((actualSelfX - actualTargetX), 2) + math.pow((actualSelfY - actualTargetY), 2)) * multiplier
        distance = math.floor(dist + 0.5)
            
        -- Disable range functionality when a zone isn't working with range calculation
        if distance > 100 then
                distance = -999
        end
 
        if distance >= 0 then
                theRange = distance
        end
    end
        
    return {
    range = theRange,
    dist = multiplier
    }
end

That is the function I used from RangeReticle to test with. I basically turned it into a function I could pass the arguments to of the Node. So say the Node is a fishing hole, I was passing the locations of all the fishing holes to that function.

for i = 1, #sv do
        local item = sv[i]
        
        d("Range of loot : " .. getTargetDistance(item[1], item[2]).range)
    end

Just to see what the values were, and what it returned. It returns a nice neat distance of 0 to, oh say 48 meters.

Well that is a lot to calculate, and I could ask permission to use the code, but I want to use my own code. In fact all I really want to use is Standard Form of (x-a)2 + (y-b)2 = r2. I can't get (a,b) from GetMapPlayerPosition('reticleover') unless it's an NPC.
