LUA scripting issues

[---nikoli]

Although I've successfully made a script that rotates back and forth +/- 45° on the 'Y' axis and attached it to a Hook5 mesh object CCTV camera, a camera image, and linked it to a screen to show an image like a real one would. I'm having issues figuring out how this game reads LUA's.

 

 

 

My issue is I've been unable to figure out how to make them work if the mesh or the cameras initial orientation is something other than 0° on the 'Y' axis.

 

This script works but only if the objects 'Y' orientation is set to 0°. I've been attempting to have it work with orientations other than 0° but so far, every script alteration I've tried either locks up the mesh and camera or locks up all scripts in the game until I close the game out and restart it.

------------------------------------------------------------------------------------------------------

local script = {}
--SCRIPT BODY - any functions and calculations
--====================================================================================================
--main function that will be used as frame update callback
--id         - object id allow access to object storage
--delta     - time passed from last frame, i.e frame time
local function update( id, delta ) 

    --here the main script things logic, calculations and so on
    local st = db.storage[id]
    if st then
        st.object.rotation = st.object.rotation + Vector3( 0, st.speed, 0 ) * delta
        if st.object.rotation.y >= 45 then
            st.speed = -st.speed
        elseif st.object.rotation.y <= -45 then
            st.speed = -st.speed
        end
    end
end

--================================================================================================
--BIND - this function called when object binded with script and allow register all desired callbacks
--================================================================================================
function script:bind_to_object( st, binder )--object storage and callback binder
    
    --declare per object variables
    st.speed = 10 --degree in sec
    
    --register callback in array of active callbacks
    binder:add_callback( CALLBACK_GLOBAL, "on_frame_update", st.object.id, update )
    --callback class
    --callback type
    --object id
    --function that will be used as callback
end
--====================================================================================================
--script registration
db.script_list["sc_object_cctv"] = script

 

 

 

Partial examples of failed attempts that lock/disable all scripts until restart. These 'should' work, but don't. --- Any suggestions would be welcome.

Attempt 01 ------------------------------------------------------------------------------------------------------

    local st = db.storage[id]
    if st then
        local currentRotation = st.object.CFrame:toEulerAnglesXYZ()
        st.object.rotation = currentRotation + Vector3( 0, st.speed, 0 ) * delta
        if st.object.rotation.y >= 45 then
            st.speed = -st.speed
        elseif st.object.rotation.y <= -45 then
            st.speed = -st.speed
        end
    end
end

Attempt 02 ------------------------------------------------------------------------------------------------------

    local st = db.storage[id]
    if st then
        local currentRotation = st.object.CFrame:toEulerAnglesXYZ()
        local newRotation = CFrame.Angles(0, currentRotation.y + st.speed * delta, 0)
        st.object.CFrame = st.object.CFrame * newRotation
        if currentRotation.y >= math.rad(45) then
            st.speed = -st.speed
        elseif currentRotation.y <= math.rad(-45) then
            st.speed = -st.speed
        end
    end
end

Attempt 03 -------------------------------------------------------------------------------------------------------

    local st = db.storage[id]
    if st then
        local currentRotation = st.object.CFrame:toEulerAnglesXYZ()
        local newRotation = CFrame.fromEulerAnglesXYZ(0, currentRotation.y + st.speed * delta, 0)
        st.object.CFrame = st.object.CFrame * newRotation
        if currentRotation.y >= math.rad(45) then
            st.speed = -st.speed
        elseif currentRotation.y <= math.rad(-45) then
            st.speed = -st.speed
        end
    end
end
