Clear Cache - Option in the editor

[klepto2]

I promote this suggestion because:

In the latest weeks you made a great progress with the editor, but while testing the editor with lots of files i found some things which could be made easier if a small clear cache function is integrated: Also this function is more or less a very easy one to implemnt.

• In the latest updates you suggested multiple times to delete the thumbnail folder
• The overall cache can grow extremely in size and to easily clean it up from the editor would be handy
• the clear cache should be optionally global or per project

I am pleased this worked perfectly. Just place this Lua file somewhere in Ultra Engine/Scripts/Start:

 

local extension = {}

function extension.NukeDir(path, extension)
    local files = LoadDir(path)
    for n = 1, #files do
        local filepath = path.."/"..files[n]
        if FileType(filepath) == 2 then
            extension.NukeDir(filepath, extension)
        else
            DeleteFile(filepath)
        end
    end
    DeleteDir(path)
end

function extension.hook(event, extension)
    if event.id == EVENT_WIDGETACTION then
        if event.source == extension.menuitem then
            local path = GetPath(PATH_PROGRAMDATA).."/Ultra Engine/Thumbnails"
            if FileType(path) == 2 then
                extension.NukeDir(path, extension)
            end
            Print("Thumbnail cache cleared.")
            return false
        end        
    end
end

-- Add menu item
--------------------------------------------------------------------

local menu = program.menu:FindChild("Scripting", false)
if menu == nil then
    Print("Error: Could not find \"Scripting\" menu.")
    return
end

local submenu = menu:FindChild("Utilities", false)
if submenu == nil then
    submenu = CreateMenu("Utilities", menu)
end
extension.menuitem = CreateMenu("Clear thumbnail cache", submenu)

ListenEvent(EVENT_WIDGETACTION, extension.menuitem, extension.hook, extension)
