Extremely Hard Script (To me haha!)

[12p]

Ok I'm actually working on Minecraft Classic gamemode. I can't make 1 thing, I have been working hours and hours and I can't find the solution to this problem.

I don't know what code it's supposed I give you so you tell me with the following ideas of my script (because I may pass you an useless part and you-me don't want to show whole code):

-Using a cursor "mode".

-Clicking on a perfect 1x1x1 cube that is placed on a perfect 3D grid.

-Checking cube's face.

-Creating a cube next to that cube face.

You tell me what I must show, I will do.

Please help me, I can't progress with this damn script!

This is one way how you could do it:

1) Detect the click with onClientClick, it will give you the blockElement and the position clicked on (worldX, worldY, worldZ).

2) Calc the distances between the block's position and world position in x,y,z .

3) The biggest distance is the axis matching the face you clicked on

4) Now the direction is positive on the axis if that distance is +, it's negative on the axis if it's <0

addEventHandler('onClientClick', root, 
function(button, state, absoluteX, absoluteY, worldX, worldY, worldZ, clickedCube) 
    -- get the position of the clicked cube (assuming this is the center of the cube) 
    local cubeX, cubeY, cubeZ = getElementPosition(clickedCube) 
  
    -- calc the differences between the two points 
    local difX, difY, difZ = worldX - cubeX, worldY - cubeY, worldZ - cubeZ 
  
    -- see which face was clicked by checking the longest distance 
    if math.abs(difX) >= math.abs(difY) and math.abs(difX) >= math.abs(difZ) then 
        -- the click was one the x-axis, now look what direction on the axis 
        if difX > 0 then 
            createCube ( worldX + 1, worldY, worldZ ) 
        else 
            createCube ( worldX - 1, worldY, worldZ ) 
        end 
  
    elseif math.abs(difY) >= math.abs(difX) and math.abs(difY) >= math.abs(difZ) 
        -- the click was one the y-axis, now look what direction on the axis 
        if difY > 0 then 
            createCube ( worldX , worldY + 1, worldZ ) 
        else 
            createCube ( worldX , worldY - 1, worldZ ) 
        end 
  
    elseif math.abs(difZ) >= math.abs(difX) and math.abs(difZ) >= math.abs(difY) 
        -- the click was one the z-axis, now look what direction on the axis 
        if difZ > 0 then 
            createCube ( worldX , worldY, worldZ + 1 ) 
        else 
            createCube ( worldX , worldY, worldZ - 1 ) 
        end 
    end 
end 
)

Gonna test! OMG this was my script (basing myself on normal "minecraft block placing" without modifications "tweaks"):

function getClearPosition (pl,px,py) 
  
    local x,y = getElementPosition(pl) 
     
    --Distances between X and Y points 
    local  = x - px 
    local yd = y - py 
     
    --If the distance between X or Y points is more than 1 player won't get bug with cube collision 
    --The clear X or Y point is "zero - distance" divided by "the distance's absolute value" 
    --This point returns a "1" integer that has the right type (negative or positive) 
     
    if math.abs() > 1 then  
        finalX = round(( / math.abs()) + px) --"+ px" because I want to put it next to the cube I click on. 
    end 
     
    if math.abs(yd) > 1 then 
        finalY = round((yd / math.abs(yd)) + py) 
    end 
     
    if finalX and finalY then 
        return finalX,finalY 
    else 
        return false,false 
    end 
end

Yeah, that's another way of doing it, but I think it's less accurate ( could be wrong tho )
